GB/T 9639.1

Test Materials: The GB/T 9639.1 standard specifies the use of various materials such as test specimens made from specified types of plastics or composites. These materials should be prepared according to defined dimensions to ensure consistency and accuracy during testing.

Test Process: The testing involves applying a defined load to the specimen under controlled conditions. This may include environmental factors like temperature and humidity to mimic real-world applications. The process requires specific equipment calibrated to measure the material’s response to stress accurately.

Test Result Interpretation: Results are analyzed based on the material’s ability to withstand the applied load without failure. Key parameters include the maximum load sustained and any observable deformation. The findings are compared against the criteria outlined in GB/T 9639.1 to determine compliance and material performance.
