Standard Guide for Developing Specifications for Masonry Units

Standard Guide for Developing Specifications for Masonry Units

SIGNIFICANCE AND USE
5.1 This guide is intended to provide guidance for developing ASTM unit specifications for nontraditional masonry units. The user of this guide is encouraged to review the Form and Style for ASTM Standards as well as the referenced unit specifications and test methods. Note that not all items presented in this guide are necessarily applicable or appropriate in all cases.  
5.2 ASTM specifications are not intended for proprietary products, but rather for a class of products that multiple manufacturers can produce, and are intended to ensure performance using those constituent materials or processes. Therefore, specific attributes that only relate to a specific brand should be avoided.  
5.3 This guide does not identify the complete range of considerations that may be required for a masonry unit manufactured using a non-traditional material. Traditional masonry units possess intrinsic properties that are commonly associated with masonry including but not limited to strength, fire resistance, durability, thermal and acoustical attributes.  
5.4 Non-traditional masonry unit products may meet all the physical property requirements of an existing ASTM standard unit specification, when tested using ASTM standard test methods. Nevertheless, performance of non-traditional masonry units is not assured since the intrinsic properties that are associated with traditional masonry units and assemblies may not be specifically evaluated through testing for specification compliance. Additionally, compliance with the physical properties in existing unit specifications does not mean that non-traditional units are in compliance with those specifications as traditional unit standards are only applicable to units produced with those materials and processes defined within that specification (refer to Appendix X1).
SCOPE
1.1 This guide provides general guidance for developing ASTM unit specification for masonry units manufactured with constituent materials, manufacturing methods, and combinations thereof, that are not included in a current ASTM standard. This guide shall not be construed as permitting the use of a product conflicting with requirements of the governing building code.  
1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Practice for Installation Methods for Cement-based Adhered Masonry Veneer

SCOPE
1.1 This practice is intended to provide accepted procedures to designers and installers of cement-based adhered masonry veneer in residential and commercial construction. This information is meant to complement the specific installation instructions provided by manufacturers of cement-based adhered masonry veneers and recognized building codes, but is not meant to replace them. This practice does not address installation methods or techniques for all materials in the building envelope. This practice covers the installation of cement-based adhered masonry veneer units for application as adhered veneer to exterior and interior walls, columns, landscape structures and other structures suitable to receive adhered veneer. The units included in this practice are manufactured to meet the requirements of Specification C1670/C1670M or C1877. This practice is limited to the installation of units. This practice does not cover all flashing or moisture management requirements. Refer to the applicable building code and project documents for additional flashing and moisture management requirements.
Note 1: The National Concrete Masonry Association (NCMA) publication Installation Guide and Detailing Options for Compliance with ASTM C1780 for Adhered Manufactured Stone Veneer provides generally accepted methods and details for installation and flashing for manufactured stone veneer.
Note 2: This standard was developed for the installation of cement-based adhered veneer units manufactured from wet-cast concrete or dry-cast concrete. Refer to Guide C1242 for installation of adhered natural stone veneer.  
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.3 All workmanship and materials related to the installation of cement-based adhered masonry veneer units shall meet the requirements of the contract documents and building code having jurisdiction over the project.  
1.4 The text of this standard references notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. (Warning—Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure.2)  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Test Methods for Strength of Anchors in Masonry

SIGNIFICANCE AND USE
4.1 These test methods are intended to provide reproducible data from which acceptance criteria, design data, and specifications can be developed for anchors intended to be installed in masonry assemblies.
SCOPE
1.1 These test methods address the tensile and shear strengths of post-installed and placed-during-construction anchors in masonry test specimens made of masonry assemblies. Environmental exposures include freezing and thawing, moisture, decreased and elevated temperatures and corrosion. These test methods provide basic testing procedures for use with product-specific evaluation and acceptance standards and are intended to be performed in a testing laboratory. Product-specific evaluation and acceptance standards may add specific details and appropriate parameters as needed to accomplish the testing. Only those tests required by the specifying authority need to be performed.  
1.2 Loadings include quasi-static, dynamic, fatigue and shock. Environmental exposures include freezing and thawing, moisture, decreased and elevated temperatures and corrosion.  
1.3 These test methods are intended for use with post-installed and placed-during-construction anchors designed for installation projecting from the surface of a masonry test specimen.  
1.4 This standard prescribes separate procedures for static, dynamic, fatigue and shock testing. Nothing in this standard, however, shall preclude combined tests incorporating two or more of these types of loading (such as dynamic, fatigue and shock tests in series).  
1.5 The text of this standard refers to notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.  
1.6 Both inch-pound and SI units are provided in this standard. The testing may be performed in either system and reported in that system and the results converted to the other. However, anchor diameters, threads, and related testing equipment shall be in accordance with either inch-pound or SI provisions.  
1.7 Units—The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.  
1.8 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.9 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM C1531-22(Test Method)
Standard Test Methods for In Situ Measurement of Masonry Mortar Joint Shear Strength Index

SIGNIFICANCE AND USE
5.1 This test method provides a means of evaluating the horizontal in-plane shear behavior of mortar joints in existing unreinforced masonry assemblies (see Note 2).
Note 2: The masonry mortar joint shear strength index obtained by this test method can be related to the masonry wall shear strength by relationships contained in referencing Codes and Standards. For example, formulas relating shear index to wall shear strength are found in Chapter A1 of the International Existing Building Code and Chapter 11 of the Seismic Evaluation and Retrofit of Existing Buildings, ASCE Standard ASCE/SEI 41. The user of this standard is cautioned that these shear strength relationships are typically empirical relationships based on tests of early 20th-century unreinforced brick masonry. These relationships typically assume that wall shear strength is limited by shear of the mortar joints rather than shear through the units  
5.2 For hollow ungrouted or solid unit masonry construction the shear strength index is measured only for the mortar bed joints vertically adjacent to the unit being tested. When testing hollow ungrouted masonry construction, the shear strength index is based on the horizontal interface between the mortar and the test unit and the masonry above and below the test unit. In the case of multi-wythe construction, the measured mortar joint shear strength index is applicable only to the wythe in which the test unit is located; no headers shall exist immediately above or below the test unit. The contribution of any existing collar joint mortar to the measured shear strength index is neglected, and this may lead to an overestimate of the shear strength index (see Note 3).
Note 3: Some documents that reference this test method, including ASCE/SEI 41, include a reduction factor to account for the contribution of a filled collar joint to the measured shear strength index.  
5.3 The test procedure listed for Method A may be conducted as an extension of Test Method C1...
SCOPE
1.1 These test methods cover procedures for the determination of the average in situ mortar joint shear strength index in existing unreinforced solid-unit and ungrouted hollow-unit masonry built with clay or concrete units. Three methods are provided:  
1.1.1 Method A (with Flatjacks Controlling Normal Compressive Stress)—For determining mortar joint shear strength index when the state of normal compressive stress at the test site is controlled during the test using the flatjack method described in Test Method C1197. Horizontal displacement of the test unit is monitored throughout the test. The test setup for Method A is shown in Fig. 1.
FIG. 1 Test Setup—Method A  
Note 1: A paper2 by Francesco Graziotti et. al of Univ. of Pavia included in ASTM STP 1612 discusses alternative methods for interpreting Method A testing results.  
1.1.2 Method B (without Flatjacks Controlling Normal Compressive Stress)—For determining mortar joint shear strength index when using an estimate of the normal compressive stress at the location of the test site. Horizontal displacement of the test unit is not monitored during this procedure. The test set up for Method B is shown in Fig. 2.
FIG. 2 Test Setup—Method B  
1.1.3 Method C (with Flatjack Applying Horizontal Load)—For determining mortar joint shear strength index using an estimate of the normal compressive stress at the location of the test site, as shown in Fig. 3. Horizontal displacement of the test unit is generally not measured during this procedure.
FIG. 3 Test Setup—Method C  
1.2 The text of this standard refers to notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.  
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for informat...

Standard Practice for Selection, Removal, and Shipment of Manufactured Masonry Units and Masonry Specimens from Existing Construction

SIGNIFICANCE AND USE
4.1 Masonry specimens are sometimes removed as part of an assessment of the condition of masonry construction. Such specimens are commonly prepared for shipment to a laboratory where the specimens are assessed with visual techniques, petrographic techniques, or standard test methods. The process of selecting, removing, and shipping the specimens can have an effect on test results. This practice provides procedures for selecting, removing, and shipping masonry specimens removed from existing construction.  
4.2 The selection and removal processes described in this practice are primarily intended for walls. Selection and removal of masonry specimens from locations other than walls requires user judgment in order to obtain appropriate specimens.  
4.3 This practice also covers reporting of the selection, removal, and shipping processes. This information allows interested parties to assess the impact of these processes on test results.  
4.4 This practice does not address the use of test results conducted on removed masonry specimens. This practice does not determine whether the removed masonry materials met original specification requirements.
SCOPE
1.1 This practice covers the process of selection, removal, and shipment of masonry specimens from existing construction that are intended for testing. These specimens can be either individual masonry units or assemblages. Assemblages are a portion of existing masonry, typically consisting of masonry units, mortar, grout, reinforcing steel, collar joint, and masonry accessories. The specimens may be taken from single- or multiple-wythe construction, or portions thereof. This practice also covers procedures for reporting as part of this process.  
1.2 The text of this standard refers to notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.  
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Test Method for Field Determination of Water Penetration of Masonry Wall Surfaces

SIGNIFICANCE AND USE
4.1 This non-destructive test method contains procedures and equipment requirements to quantitatively determine the surface penetration of water at a single location on a masonry wall. The test method is not designed to determine the overall water penetration and leakage of a masonry system.  
4.2 Excessive water penetration of masonry may degrade masonry wall performance with respect to thermal conductivity, durability, efflorescence, staining, corrosion of embedded metal items, and water leakage.  
4.3 This test may be used to measure the rate of surface water penetration for in-situ masonry and field mockups. Common applications of this method have been comparison of water penetration rates of walls before and after repairs, and testing the efficacy of coatings. Alternative procedures are also provided to simulate the effect of local climatology on water penetration of masonry wall surfaces.  
4.4 The outer surface of all masonry walls will experience water penetration when subjected to wind-driven rain. The resistance to water penetration is dependent on materials, workmanship, design, and maintenance. Some wall types accommodate large volumes of water penetration, without deleterious effects, through the presence of properly designed and installed drainage systems including flashing and weep holes. Use of this standard without consideration of the overall wall system may lead to incorrect conclusions regarding performance.  
4.5 It is the intent of this standard that a sheet of water be developed and maintained on the wall surface during testing. In some cases, due to the surface texture of the masonry, the application of a coating, or other factors, a sheet of water will not consistently form. In those cases, results of this test method will likely be inaccurate.  
4.6 This test method is similar to but distinct from the laboratory Test Method E514/E514M. This standard is a field test method designed to test in-situ walls and measures water penetration of...
SCOPE
1.1 This test method covers the field determination of water penetration of a masonry wall surface under specific water flow rate and air pressure conditions. This test is intended for use on any masonry wall surface that can be properly instrumented and tested within the requirements of this standard. This test method is not identical to and the results are not the same as laboratory standard Test Method E514/E514M. Test Method E514/E514M measures through-wall water penetration, whereas this test method only measures surface water penetration.  
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM C1715/C1715M-22(Test Method)
Standard Test Method for Evaluation of Water Leakage Performance of Masonry Wall Drainage Systems

SIGNIFICANCE AND USE
5.1 This test method is suitable for use on walls to determine the ability of masonry wall drainage systems to collect water penetrating the exterior wythe and to direct this water back to the exterior surface of the exterior wythe. Removal of a portion of the interior wall finishes is desirable to observe leakage into backup walls. Even with removal of interior finishes, in many cases it is not practical to observe surfaces behind spandrel beams, columns, or other obstructions. Potential areas where leakage may occur but that are not visible during the test shall be considered when interpreting the results of the test and shall be recorded in the report.  
5.2 This test method is suitable for use on mock-up walls to determine the performance of masonry wall drainage systems.  
5.3 This test method is suitable for evaluating the effectiveness of flashing repairs.
SCOPE
1.1 This test method describes a standard procedure for determining the ability of masonry wall drainage systems to collect water that penetrates the exterior masonry wythe during rainstorms and to direct this water back to the exterior surface of the wall.  
1.2 This test method is applicable to wall systems that contain an exterior masonry wythe with a drainage zone on the interior face of the exterior wythe. It is not applicable to single-wythe drainage walls.  
1.3 This test method is not applicable to masonry barrier walls or other masonry walls that are designed without drainage zones behind the exterior wythe.  
1.4 This test method covers the application of the testing using either inch-pound or SI units. The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, the inch-pound units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

Standard Test Method for Water Penetration and Leakage Through Masonry

SIGNIFICANCE AND USE
4.1 This test method provides information that aids in evaluating the effect of four principal variables: materials, coatings, wall design, and workmanship.  
4.2 Water penetration and leakage through masonry is significantly affected by air pressure in the test chamber. Data from tests made at different pressures are not comparable.  
4.3 The performance of a masonry wall is a function of materials, construction, wall design, and maintenance. In service the performance will also depend on the rigidity of supporting structure and on the resistance of components to deterioration by various causes, such as corrosion, vibration, thermal expansion and contraction, curing, and others. It is impossible to simulate the complex conditions encountered in service, such as variations in wind velocity, negative pressure, and lateral or upward moving air and water. Factors such as location, exposure, and wall openings should be considered.  
4.4 Given the complexity of variables noted above, this test method establishes comparative behavior between various masonry wall constructions in a given laboratory.  
4.5 Even when a single laboratory tests the same wall design utilizing the same wall materials and the same construction practices, variables such as the level of skill of the mason building the specimen, the temperature and humidity in the laboratory at the time of construction, curing of the specimen, the moisture contents of the materials used to build the specimen, and even the use or lack of use of a lime and water wash on the back of the specimen can affect the results of the test making reliable comparisons dubious. For these reasons and the multi-variables listed in 4.1, 4.2, and 4.3, a meaningful, useful, absolute wall leakage rating standard is impractical and discouraged.  
4.6 This test method is similar to but distinct from field Test Method C1601. This standard is a laboratory test method designed to test laboratory fabricated wall specimens and measures th...
SCOPE
1.1 This laboratory test method2 provides a procedure for determining the resistance to water penetration and leakage through unit masonry subjected to wind-driven rain. This test method is not identical to and the results are not the same as field standard Test Method C1601. This test method measures through-wall water penetration, whereas Test Method C1601 only measures surface water penetration.  
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For a specific hazard statement, see Section 6.

Standard Guide for Developing Specifications for Masonry Units

SIGNIFICANCE AND USE
5.1 This guide is intended to provide guidance for developing ASTM unit specifications for nontraditional masonry units. The user of this guide is encouraged to review the Form and Style for ASTM Standards as well as the referenced unit specifications and test methods. Note that not all items presented in this guide are necessarily applicable or appropriate in all cases.  
5.2 ASTM specifications are not intended for proprietary products, but rather for a class of products that multiple manufacturers can produce, and are intended to ensure performance using those constituent materials or processes. Therefore, specific attributes that only relate to a specific brand should be avoided.  
5.3 This guide does not identify the complete range of considerations that may be required for a masonry unit manufactured using a non-traditional material. Traditional masonry units possess intrinsic properties that are commonly associated with masonry including but not limited to strength, fire resistance, durability, thermal and acoustical attributes.  
5.4 Non-traditional masonry unit products may meet all the physical property requirements of an existing ASTM standard unit specification, when tested using ASTM standard test methods. Nevertheless, performance of non-traditional masonry units is not assured since the intrinsic properties that are associated with traditional masonry units and assemblies may not be specifically evaluated through testing for specification compliance. Additionally, compliance with the physical properties in existing unit specifications does not mean that non-traditional units are in compliance with those specifications as traditional unit standards are only applicable to units produced with those materials and processes defined within that specification (refer to Appendix X1).
SCOPE
1.1 This guide provides general guidance for developing ASTM unit specification for masonry units manufactured with constituent materials, manufacturing methods, and combinations thereof, that are not included in a current ASTM standard. This guide shall not be construed as permitting the use of a product conflicting with requirements of the governing building code.  
1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM C1780-23a(Practice)
Standard Practice for Installation Methods for Cement-based Adhered Masonry Veneer

SCOPE
1.1 This practice is intended to provide accepted procedures to designers and installers of cement-based adhered masonry veneer in residential and commercial construction. This information is meant to complement the specific installation instructions provided by manufacturers of cement-based adhered masonry veneers and recognized building codes, but is not meant to replace them. This practice does not address installation methods or techniques for all materials in the building envelope. This practice covers the installation of cement-based adhered masonry veneer units for application as adhered veneer to exterior and interior walls, columns, landscape structures and other structures suitable to receive adhered veneer. The units included in this practice are manufactured to meet the requirements of Specification C1670/C1670M or C1877. This practice is limited to the installation of units. This practice does not cover all flashing or moisture management requirements. Refer to the applicable building code and project documents for additional flashing and moisture management requirements.
Note 1: The National Concrete Masonry Association (NCMA) publication Installation Guide and Detailing Options for Compliance with ASTM C1780 for Adhered Manufactured Stone Veneer provides generally accepted methods and details for installation and flashing for manufactured stone veneer.
Note 2: This standard was developed for the installation of cement-based adhered veneer units manufactured from wet-cast concrete or dry-cast concrete. Refer to Guide C1242 for installation of adhered natural stone veneer.  
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.3 All workmanship and materials related to the installation of cement-based adhered masonry veneer units shall meet the requirements of the contract documents and building code having jurisdiction over the project.  
1.4 The text of this standard references notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. (Warning—Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure.2)  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
