Standard Test Method for Failure End Point in Accelerated and Outdoor Weathering of Bituminous Materials
 N D1670/D1670M

Annotation

This test method covers the use of a spark generating apparatus for determination of failure due to cracking of bituminous materials undergoing accelerated or outdoor weathering on electrically conductive backings.

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.

Метод стандартной пробы для конечной точки неудачи в ускоренном и наружном наклоне битумных материалов

Этот метод тестирования покрывает использование генерирующегося аппарата искры для определения отказа вследствие взламывания битумных материалов, подвергающихся ускоренному или наружному наклону на электрически проводящих поддержках.
