Abstract: In this work， we analyzed the factors affecting the tensile experimental results of thermoplastic polyethylene pipes， which included the ambient temperature and tensile test speed. The results indicated that the tensile performance of the pipes was greatly influenced by the test speed and the test ambient temperature. The test was conducted in strict accordance with the standard conditions to minimize personnel and environmental change factors that affect the test results. Through multi?group test and data analysis， the influence of test temperature and standard test temperature of the PP pipe are presented.

Key words: polyethylene, tensile strength, fracture elongation
