Standard Practice for Determination of 2 % Secant Modulus for Polyethylene Geomembranes
N D5323
Annotation
This practice presents a technique for calculating the 2 % secant modulus for polyethylene geomembranes between 0.5 and 5 mm (20 and 200 mil) using Test Method D638.
This practice will facilitate modulus comparisons of similar materials by standardizing the method for deriving the points on the stress-strain curve from which the calculations are performed.
The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
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 consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Общепринятая практика для определения 2%-го секущего модуля для полиэтилена Geomembranes
Эта практика представляет метод для вычисления 2%-го секущего модуля для полиэтилена geomembranes между 0.5 и 5 мм (20 и 200 mil) использование Метода испытаний D638.
Эта практика упростит сравнения модуля подобных материалов путем стандартизации метода для получения пунктов на кривой "нагрузка-удлинение", от которой выполняются вычисления.
