At a minimum, the two parties should take a group of test specimens which are as homogeneous as possible and which are from a lot of material of the type in question.

Further use of this table is de? In cases of dispute, take a sample that will exclude fabric from the outer wrap of the roll or the inner wrap around the core. Comparative tests as directed in 5. Tensile strength, elongation, initial and secant modulus, and breaking toughness of the test specimen can be calculated from machine scales, dials, recording charts, or an interfaced computer.

The intersection point A9 is the zero elongation point from which elongation is measured. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Determine the number of specimens as follows: Likewise, label a second point, P1 at a speci?

At any point on this tangent line, measure the force and the corresponding elongation with respect to the zero force axis.

If a bias is found, either its cause must be found and corrected or the purchaser and the supplier must agree to interpret future test results in light of the known bias. In any event, the procedure described in Section 10 of this test method for obtaining wide-width strip tensile strength must be maintained.

The sample may be taken from the end portion of a roll provided there is no evidence it is distorted axtm different from other portions of the roll.

ASTM D Wide-Width Tensile Test Equipment for Geotextiles

aetm Test 2 Method D for the determination of the wide-width d45995 tensile properties of geotextiles may be used for the acceptance testing of commercial shipments of geotextiles but caution is advised since information about between-laboratory precision is incomplete Note 6.

The wide-width strip technique has been explored by the industry and is recommended in these cases for geotextile applications. In some cases, it may also be caused by a concentration of stress in the area adjacent to the jaws because they prevent the specimen from contracting in width as the force is applied. In those cases, mm 4-in. Approximately equal force increments should be used throughout the application of force having the?

ASTM D – Wide-Width Geotextiles

A time of at least 24 h has been astk acceptable in most cases. This width, by contrast, is greater than the length of the specimen. Within this limitation, the procedures in Test Method D has no known bias.

The determination 4d595 the wide-width strip force elongation properties of geotextiles provides design parameters for reinforcement type applications. Test Method D for the determination of the wide-width strip sstm properties of geotextiles may be used for the acceptance testing of commercial shipments of geotextiles, but caution is advised since information about between-laboratory precision is incomplete Note 6.

As a minimum, the two parties should take a group of test specimens which are as homogeneous as possible and which are from a lot of material of the type in question.

Comparative tests as directed in 5.

This is particularly the case for nonwoven geotextiles. This intersection, point B, is the zero elongation point from which elongation is measured. Historical Version s – view previous versions of standard.

This is particularly the case for nonwoven geotextiles. In these cases, a break near the edge of the jaws is inevitable and shall be accepted as a characteristic of the particular method of test.

Some fabrics used in geotextile applications have a tendency to contract neck down under a force in the gage length area. This test method is applicable to most geotextiles that include woven fabrics, nonwoven fabrics, layered fabrics, knit fabrics, and felts that are used for geotextile application. NOTE 5—Some clamping arrangements may lead to slack in the specimen within the gage area.
