ASTM D1171 – Standard Test Method for Rubber Deterioration—Surface Ozone Cracking Outdoors (Triangular Specimens)
Description:
Significance and Use
4.1 Molded or extruded rubber products must withstand the effects of ozone cracking and outdoor weathering for satisfactory use. This test enables a simple comparison of performance to be made under specified test conditions in an outdoor test. No direct correlation between test performance and service performance can be claimed due to the wide range of service conditions.
Scope
1.1 This test method permits the estimation of the relative ability of rubber compounds used for applications requiring resistance to outdoor weathering.
1.2 This test method is not applicable to materials ordinarily classed as hard rubber, but is adaptable to molded or extruded soft rubber materials and sponge rubber for use in window weatherstripping as well as similar automotive applications.
