Abstract��According to the test method GB/T 528-2009 Rubber,vulcanized or thermoplastic-determination of tensile stress-strain properties, tensile strength of the polyurethane elastomer were determined. The main sources of uncertainty resulted from the determination process were discussed and calculated. The expanded standard uncertainty of tensile strength determination was 1.12 MPa when the tensile strength was 49.2 MPa.
