The standard practices defined in the ASTM D499 standard developed by the American Society for Testing and Materials (ASTM) cover the specific procedures and test conditions applicable to the exposure of plastics in filtered open-flame carbon arc devices operated in accordance with ASTM G151 and ASTM G152 standards. This practice also includes the preparation of test specimens, appropriate test conditions for plastics, and evaluation of test results.
This standard, whose full name is "ASTM D1499-13 Standard practice for filtered open flame carbon arc exposure of plastics", does not cover closed carbon arc exposures of permitted plastics. Exposure of plastics to closed carbon arc is described in ASTM D6360 and ASTM G153 which gives requirements for the exposure of non-metallic materials in closed carbon arc devices.
Advanced laboratories provide multiple tests to measure the degradation of a material in light, heat and water environments. Carbon arc testing is a test method that provides information on material changes in properties under conditions of accelerated exposure to weathering conditions such as artificial light, sunlight, humidity, and heat.
The carbon arc decomposition system provides more UV exposure at wavelengths below 300 nm than natural sunlight alone. The open-flame carbon arc light source tests the light-fastness durability of materials and coatings using three pairs of carbon rods that emit ultraviolet, visible, and infrared radiation when an electric current is passed between them. It uses temperature control with carbon arc, black panel sensor and sample conditioning water.
The ability of a plastic material to resist degradation of its electrical, mechanical, and optical properties caused by exposure to light, heat, and water is crucial for many applications. This practice aims to cause property changes associated with end-use conditions, including the effects of sunlight, humidity, and heat.
Among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors, our organization also provides standard testing services for filtered open flame carbon arc exposure of plastics, within the scope of ASTM D1499-13 standard, with its trained and expert staff and advanced technological equipment. .
