ASTM D1148 is a series of test standards issued by the American Society for Testing and Materials (ASTM International). Sonacme Technology's UV aging tester has high flexibility and adaptability in design and function, and can simulate a variety of natural environmental conditions, including UV radiation, temperature, humidity, etc., to meet the test requirements of ASTM D1148.

Overview of ASTM D1148

The ASTM D1148 standard is mainly used to evaluate the heat resistance, oxidation resistance and UV resistance of rubber materials. By simulating harsh environments such as high temperatures, oxidation and UV radiation, the standard can comprehensively test the changes in the performance of rubber materials under these conditions, providing an important basis for the production, material selection and quality control of rubber products.

Test Requirements for ASTM D1148

For evaluating the discolouration properties of white or light-coloured vulcanised rubber products, the ASTM D1148 standard specifies specific UV and thermal environmental conditions. These conditions typically include a certain relative humidity, haze, temperature, and intensity of UV or UV/visible light exposure. Under these conditions, rubber samples are subjected to a certain number of light cycles, and the degree of discolouration is then determined by comparing it to a comparison sample that is irradiated together. These tests help to understand the chemical stability of rubber materials in harsh environments.

Application Areas of ASTM D1148

The ASTM D1148 standard has a wide range of applications in a number of areas, including but not limited to： 

Rubber product production: To provide guidance and assurance for the production of rubber products to ensure that they perform as expected under high temperatures, oxidation and other environments.

Material Selection: as the basis for material selection, to help users choose rubber materials that meet the expected performance.

Quality control: Used in the production and quality control of rubber materials to ensure that the rubber materials produced meet the expected performance requirements.
