NOTE 1 Where it is impracticable for the mass to hit the profile in accordance with 7.2 due to

14、its geometry, other impact positions for the falling mass should be agreed upon between the profile manufacturer and the testing laborahq. NOTE 2 When due to its geometry, the profile tends to tilt sideways at the impact of the falling mass, any tilting should be prevented, by attaching additionai s

NOTE 3 During the test care should be taken to prevent multiple impacts of the faiiing mass on the test piece. 8 Expression of results The number of test pieces tested and the number of test pieces broken shall be reported for each type of main profile. 9 Tbst report The te
