ASTM D8199-20

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation: D8199 − 19 D8199 − 20
Standard Test Method for
Determining the Specific Strength of Hydraulically Applied
Fiber Matrix Products for Erosion Control
This standard is issued under the fixed designation D8199; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope Scope*
1.1 This standard provides a quantitative test method to determine the specific strength of hydraulically applied fiber matrix
products using dry and wet preparation methods in a laboratory setting. This method is designed for use as an index test for product
quality assurance or quality control, or both to comply with manufacturing requirements. This test method is not indicative of
product performance in the field.
1.2 Units—The values stated in SI units are to be regarded as the standard. The values given in parentheses are provided for
information only and are not considered standard. Reporting of test results in units other than SI shall not be regarded as
nonconformance with this standard.
1.3 All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice
D6026, unless superseded by this test method.
1.3.1 The procedures used to specify how data are collected/recorded and calculated in the standard are regarded as the industry
standard. In addition, they are representative of the significant digits that generally should be retained. The procedures used do not
consider material variation, purpose for obtaining the data, special purpose studies, or any considerations for the user’s objectives;
and it is common practice to increase or reduce significant digits of reported data to be commensurate with these considerations.
It is beyond the scope of these test methods to consider significant digits used in analysis methods for engineering data.
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.

3.2 Definitions of Terms Specific to This Standard:
3.2.1 fiber matrix product, n—in erosion control, hydraulically applied product providing enhanced and extended erosion
control protection.
4. Summary of Test Method
4.1 Ten specimens are prepared from a representative sample in accordance with Practice D7986. Five specimens are then tested
in the dry condition and five are tested in the wet condition. Each test specimen is clamped in a Constant Rate of Extension (CRE)
tensile testing machine and a force is applied to the specimen until it breaks.
4.2 The specific strength is calculated for each specimen as is the average specific strength of the five specimens tested in the
dry and wet conditions.
5. Significance and Use
5.1 Specific strength is a measure of the ability of a fiber matrix product to withstand force applied by a tensile machine and
is useful to understand in order to produce quality products. Specific strength is frequently related to the matrix density, fiber
quality, fiber length and chemistry and can be used as a measurement for quality assurance or quality control, or both requirements.
5.2 This method may not be applicable to all hydraulically applied fiber matrix products due to variations in product chemistry.
NOTE 1—The quality of the result produced by this standard is dependent on the competence of the personnel performing it, and the suitability of the
equipment and facilities used. Agencies that meet the criteria of Practice D3740 are generally considered capable of competent and objective
testing/sampling/inspection/etc. Users of this standard are cautioned that compliance with Practice D3740 does not in itself assure reliable results. Reliable
results depend on many factors; Practice D3740 provides a means of evaluating some of those factors.
6. Apparatus
6.1 Constant Rate of Extension (CRE) Type Tensile Testing Machine—A device conforming to Specification D76/D76M and
designed for operation at a speed of 300 6 10 mm/min (12 6 0.5 in./min).
6.2 Measuring Devices—CRE-type machines shall be equipped with a suitable device for measuring the force, and when
needed, a device to measure extension. These devices shall conform to Specification D76/D76M.
6.3 Clamping Devices—The clamping devices shall conform to Specification D76/D76M with the following specific properties.
The jaw faces shall be smooth, flat, and have a metallic surface. The jaw faces shall be parallel and have machining centers with
respect to one another in the same clamp and to the corresponding jaw face of the other clamp. The jaw faces shall measure at
least 10 mm (0.5 in.) wider than the specimen being tested and at least 25 mm (1.0 in.) in height.
6.4 Balance—Balances shall conform to the requirements of Guide D4753.
6.4.1 To determine the mass of the specimen, the balance shall have readability without estimation of 0.01 g. The capacity of
this balance will need to exceed the mass of the container plus a specimen. In general, a balance with minimum capacity of 600
g is sufficient.
6.5 Soaking Container—An aluminum, or equivalent inert container with enough capacity to hold five specimens and test water.
In general, a container with minimum dimensions of 100 by 200 by 6360 mm (4 by 8 by 2.52.4 in.) is typically sufficient.
6.6 Miscellaneous Items—Items such as wooden sticks, glass rods, spatulas, containers with tight fitting lids, paper towels, and
polystyrene foam plates may be useful.
7. Reagents
7.1 Test Water—Distilled, demineralized, or deionized water is the only permissible test fluid. The use of tap water is not
permitted.
