ASTM D529-04

Отменен
Standard Practice for Enclosed Carbon-Arc Exposures of Bituminous Materials (Withdrawn 2013) — 3 стр.
Причина отмены

This practice describes test conditions and procedures for enclosed carbon-arc exposures conducted according to Practices and for bituminous roofing and waterproofing materials that have a minimum softening point of approximately 95°C (200°F) as determined by Test Method . (See also Terminology .)

Formerly under the jurisdiction of Committee D08 on Roofing and Waterproofing, this practice was withdrawn in January 2013 in accordance with section 10.5.3.1 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.

Значение и использование

It is not possible to establish a precise correlation between accelerated and natural weathering because of geographical climatic variations, local weather variation from normal, and local pollutants. This weathering apparatus and procedure are used for comparing the weathering characteristics of bituminous materials against a reference material for which the outdoor weathering characteristics are known. Guide G 141 provides guidance regarding this issue.
