Ozone Exposure Testing as per ASTM D1149
Ozone Exposure Testing as per ASTM D1149
The ASTM D1149 test standard describes the ozone exposure testing procedure to measure how well different rubber products withstand exposure to ozone at varying levels. This standardized test is helpful for product research and development since it can tell whether a rubber product is ready for consumer use. After testing, the resistance of a rubber material is assessed based on its outward appearance and the severity of any surface cracks.
The sample is placed in ozone test chambers to conduct the test. These regulate the atmosphere and precisely gauge ozone levels. It is then put to the test either by using a dynamic strain method or a static strain method. These validated testing procedures subject your material to either a continuous strain for a predetermined amount of time or a single, variable maximum tensile strength level. At the conclusion of the test, the content is examined for integrity.
Materials that frequently go through ASTM D1149 testing include:
- Rubber vulcanized
- Molded or extruded soft rubber
- Compound rubber
- Components of electricity
Pairing tests for ASTM D1149 include the following:
- Testing for Salt Fog, ASTM B117
- Exposure of Non-Metallic Materials Test, ASTM G155
- UV Lamp Test for Nonmetallic Materials, ASTM G154 Exposure
- Sediment in Crude & Fuel Oils Test, ASTM D473
- Fungal Defacement Test, ASTM G21
