Standard Practice for Accelerated Weathering Test Conditions and Procedures for Bituminous Materials (Xenon-Arc Method)

Importancia y uso:

4.1 Tests conducted according to this practice are used to compare the weathering characteristics of bituminous materials versus a control material of known outdoor durability. It is not possible to establish a single relationship that is applicable to all materials between time in accelerated tests conducted according to this practice and time in natural weathering because (1) there are geographical climatic variations, local weather variations, and variations in local pollutants, and (2) the relation between accelerated and natural weathering is material dependent with differences in acceleration factors between materials as well as for different formulations of the same material. Guide G141 provides guidance regarding variability in outdoor and accelerated weathering tests and about the use of control materials.

Note 1: It is recommended that outdoor weathering be used to validate the laboratory accelerated test in terms of performance ranking.

Note 2: This practice can be used for other than bituminous materials, but the significance and use have not been evaluated.
