Standard Test Methods for Physical Testing of Gypsum Panel Products

ABSTRACT
These test methods cover the physical testing of gypsum panel products. The test methos appear in the following order: (1) flexural strength (Method A); (2) core, end, and edge hardness (Method A); (3) nail pull resistance (Method A); (4) humidified deflection; (5) end squareness; (6) nominal thickness; (7) recessed- or tapered-edge depth; (8) width; (9) length; (10) water resistance of core-treated water repellant gypsum panel products; and (11) surface water resistance of gypsum panel products with water-repellant surfaces. For use in these test methods, a sample shall consist of gypsum panel products. Flexural properties of gypsum panel products are evaluated by supporting the specimen near the ends and applying a transverse load midway between the supports. The core, end, and edge hardness of gypsum panel products is evaluated by determining the force required to push a steel punch into the area of test. The ability of gypsum panel products to resist nail pull-through is evaluated by determining the loaded required to push a standard nail head through the product. The humidified deflection of gypsum panel products is evaluated by supporting a specimen that has been cut with the long dimension perpendicular to the machine detection, supported horizontally, and subjected to high humidity.

Standard Guide for Waterproofing Repair of Concrete by Chemical Grout Crack Injection

SIGNIFICANCE AND USE
4.1 This guide is intended to be used in the selection and installation of chemical grout to seal leaks in concrete walls, floors, and ceilings. The procedure described in this guide focuses on the injection of through-wall cracks, but may be adapted to cold joints, control joints, voids associated with penetrations, and other voids contributing to water intrusion through concrete elements. This guide is intended to assist the building owner, owner’s representative, architect, engineer, contractor, or authorized inspector, or combinations thereof, during the selection, specification, or installation, or combinations thereof, of chemical grout for waterproofing repair.  
4.2 Prior to attempting any repair, it is important for all parties to have a clear and mutual understanding of the limitations of the repair and the iterative nature of the process. Injection of chemical grout does not affect the source of a leak. The repair obstructs the infiltration of water at a specific location only. The flow of water will be diverted elsewhere, and it is common for water to subsequently appear at a different location that was previously dry. A successful campaign at a given location can significantly reduce the amount of water infiltration, but may not fully prevent leakage. Given the nature of the materials and application technique, and depending on the conditions, the repairs should be periodically monitored and additional repair installations may be required.  
4.3 This guide is applicable to installations at below-grade walls and slabs. At above-grade elements, temperature variation on a daily or seasonal basis may lead to significant or more frequent changes, or both, in the width of a crack or joint. The use of injected chemical grout may be appropriate for many above-grade applications, but this guide does not specifically address installation of grout in dynamic cracks or joints.  
4.4 Cracks in below-grade walls may be a sign of structural distress. Prior to the i...
SCOPE
1.1 This guide describes the selection of materials, installation methods, and inspection required for sealing leaks at cracks in concrete building walls and slabs using chemical grout. The process discussed in this guide is a waterproofing repair in which voids in a concrete element are sealed with a reactive solution, installed by pressurized injection through drilled or surface-mounted ports.  
1.2 This guide does not address the use of chemical grout for waterproofing by curtain grouting or injection into preplaced permeable waterstop tubes. Injection of masonry elements presents additional factors beyond the scope of this guide. This guide does not address the use of injectable materials for structural repairs or for geotechnical applications such as soil stabilization.  
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 information only and are not considered standard.  
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.

Where fire resistance or shear resistance is not required, and when metal lath and Portland cement plaster are to be applied as the exterior cladding over gypsum sheathing installed over framing members and the metal lath shall be installed after the gypsum sheathing, the gypsum sheathing shall be permitted to be applied and fastening of the gypsum sheathing shall be completed with the attachment of the self-furred metal lath.
SCOPE
1.1 This specification covers the minimum requirements for and methods of application of exterior gypsum panel products that are specifically designed for use as a substrate for exterior cladding.  
1.1.1 This specification does not cover gypsum panel products that are specifically designed for interior applications.  
1.2 Details of construction for a specific assembly to achieve the required fire resistance shall be obtained from reports of fire-resistance tests, engineering evaluations, or listings from recognized fire testing laboratories.  
1.2.1 This specification shall govern where it is more stringent (size or thickness of framing and size and spacing of fasteners) than the fire-rated construction.  
1.3 Where sound control is required for a gypsum panel product assembly, the details of construction shall be in accordance with the acoustical test report of an assembly that has met the required acoustical value(s).  
1.3.1 This specification shall govern where it is more stringent (size or thickness of framing and size and spacing of fasteners) than the sound-rated construction.  
1.4 Where resistance to racking loads or shear is required for a gypsum panel product assembly, the details of construction shall be in accordance with the racking or shear test report of an assembly that has met the required racking or shear value(s).  
1.4.1 This specification shall govern where it is more stringent (size or thickness of framing and size and spacing of fasteners) than the racking or shear-tested construction.  
1.5 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.  
1.6 The text of this standard references notes which provide explanatory material. These notes shall not be considered as requirements of the standard.  
1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use.
