ISO 877-2 Plastics Methods of exposure to solar radiation
The ISO 877-2 standard is a critical method used in the testing and evaluation of plastics for their resistance to degradation under exposure to sunlight. This test protocol provides precise procedures that simulate real-world solar radiation, ensuring accurate assessment of photodegradation effects on various plastic materials.
Photodegradation is one of the primary concerns in the development and quality assurance of plastics used in textiles, electronics, automotive parts, and other sectors where prolonged exposure to sunlight can significantly impact material performance. ISO 877-2 addresses this issue by exposing specimens under controlled conditions that mimic solar radiation, thus providing a reliable method for assessing long-term durability.
The test involves two main exposure methods: one using xenon arc lamps with UV-A and UV-B light sources, and another utilizing natural sunlight filtered through glass. Both methods are designed to simulate the effects of ultraviolet (UV) rays that cause photodegradation in plastics. The standard specifies detailed procedures for setting up the test environment, including temperature control, humidity levels, and exposure time.
Specimens prepared according to ISO 877-2 undergo rigorous testing under these conditions. These tests are essential for quality assurance, as they help manufacturers and suppliers ensure that their products can withstand environmental challenges without compromising performance or safety. By adhering to this standard, companies can enhance the reliability and longevity of their plastic materials.
The standard also includes detailed acceptance criteria that define when a specimen passes or fails based on changes in physical properties such as color change, loss of tensile strength, or other measurable parameters indicative of photodegradation. Adherence to these standards ensures consistency across industries and facilitates easier compliance with international regulations.
In summary, ISO 877-2 is a vital tool for quality managers, compliance officers, R&D engineers, and procurement specialists who require precise methods to evaluate the durability of plastic materials against solar radiation. Its application in various sectors underscores its importance in maintaining high standards of product integrity and reliability.
