| Abstract: | According to the test method in GB/T 6344-2008,the tensile strength of flexible polyurethane foam was determined.The main sources of uncertainty resulted from the determination process were discussed and calculated.The results show the tensile strength of the flexible polyurethane foam was 142 kPa,and the expanded standard uncertainty of the testing results was 2 kPa when coverage factor k=2. |
