Unless otherwisespecified tolerances shall be ± 5%. Unless otherwise stated tests shall be carried out at room temperature withwater between 10 °C and 30 °C. If the designed water temperature is higher than 30 °C, the designed temperatureshall be used for the test.8.2 Mechanical Performance8.2.1 Bending strength of the body8.2.1.1 PrincipleThe mechanical bending strength of the body is tested by a bending moment test, in which a force is applied for apredetermined period.SIST EN
