The support shall be made from steel and rigidly fixed in a solid foundation or on a table with a mass of more than 50 kg; d) relecLse mechanism, such tha the falling mass can fall through a height which can be musted up to (1 500“,0) mm, measured from the top surface

Each test piece shal be tested within 10 s of removal hm the conditioning chamber. 7 Procedure 7.1 The test shall be executed on the sight surface of the main profile (prefera

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
15、tays to the two supports. 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
