ASTM D1149 - 16是關于《臭氧可控環境中橡膠變壞龜裂的標準試驗方法》現行標準版本修訂于2016年，取代原先的ASTM D1149 - 15使用。
1.1 These test methods are used to estimate the effect of exposure, under surface tensile strain conditions, either dynamic or static, in an atmosphere containing specified levels of ozone concentration, expressed as partial pressure (refer to Note 1), on vulcanized rubber, rubber compounds, molded or extruded soft rubber, and other specified materials, or as may be determined empirically. The effect of naturally occurring sunlight or light from artificial sources is excluded.
1.2 Previously published ASTM documents Test Method D518 and Test Methods D3395 have been included in these test methods, D1149, in 2007. Please refer to Note 2.
