Standard Test Method for Trapezoid Tearing Strength of Geotextiles
 N D4533/D4533M

Annotation

This test method is an index test used to measure the force required to continue or propagate a tear in woven or non-woven geotextiles by the trapezoid method. While useful for quality control and acceptance testing, the trapezoid tear test does not provide all the information needed for all design applications and other test methods should be used.

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 applications.

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.

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 and health practices and determine the applicability of regulatory limitations prior to use.

Стандартный метод испытаний для сопротивления раздиранию трапецоида Geotextiles

Этот метод испытаний является испытанием индекса, используемым для измерения силы, требуемой продолжить или распространить слезу в сотканном или нетканом geotextiles методом трапецоида. В то время как полезный для контроля качества и приемного испытания, испытание слезы трапецоида не предоставляет всю информацию, необходимую для всех приложений дизайна, и другие методы испытаний должны использоваться.
