ASTM D2990

ASTM D2990 is a standard test method that evaluates the creep and stress relaxation properties of plastic materials under continuous load over extended periods. This test is crucial for understanding how plastic materials will perform under constant stress or load, particularly in applications where long-term durability is essential. Industries such as construction, packaging, and automotive rely on plastics to maintain their integrity over time, making ASTM D2990 a key method for ensuring product reliability.

Creep testing measures how a plastic material deforms when subjected to a constant load over time, while stress relaxation testing assesses how the material’s internal stress decreases under constant strain. These tests simulate real-world conditions where plastics are exposed to sustained pressure, heat, or other environmental factors. The results of ASTM D2990 help manufacturers predict how materials will behave during their service life, allowing for better material selection and product design.
