ActiveRotational moulding—Test method for low temperature impact
滚塑成型 低温冲击试验
Application Summary AI generated
This standard specifies a test method for evaluating the low-temperature impact resistance of rotationally moulded plastic products. It is applied in the quality control and material selection processes for manufacturers producing large hollow plastic items, such as chemical storage tanks, marine buoys, and automotive fuel tanks, where the finished parts must withstand brittle fracture under cold environmental conditions.
