Evaluation criteria for test results of polymer materials

The evaluation of test results must be based on product technical specifications, procurement contract requirements, or relevant national/industry mandatory standards.

First, the raw data obtained from the experiment (such as maximum force value, deformation amount, temperature value, etc.) are used to calculate the final performance parameters using formulas specified in the standards. Then, the calculated results are compared with the preset technical requirements to determine whether they meet the specifications (pass/fail). For some performance characteristics, the evaluation criteria may be a grading system (e.g., flammability rating V-0, V-1, V-2), or require meeting a minimum value (e.g., tensile strength not less than a certain value).

The final test report should be complete and clearly presented, usually including client information, sample description, applicable standards, instruments used, test conditions, detailed test data and results, conclusions, report issuance date, and signatures of the testing personnel. The report not only provides a pass/fail conclusion, but its detailed data also serves as direct evidence for material improvement, quality traceability, and scientific research.
