ASTM D 518
Standard Test Method for Rubber Deterioration Surface Cracking (Withdrawn 2008)
Note: ASTM D 518 is no longer active and has been replaced by ASTM D 1149.
Please view the data sheet for more information and important exceptions.
Scope: This test method covers three test specimen procedures that estimate the comparative ability of rubber compounds to withstand the effects of normal weathering, or exposure in an atmosphere containing controlled amounts of ozone. It does not apply to testing of electrical insulation or other rubber parts where high concentrations of ozone prevail due to electrical discharge, nor to testing of material ordinarily classified as hard rubber.
