Embodiment 3
[0093] Tensile rate test of flat belt and safety belt for working at heights
[0094] Use the stretch rate test device of the flat belt and high-altitude operation safety belt to test the expansion ratio of the flat belt and high-altitude operation safety belt, which can be carried out according to the following methods:
[0095] (1) The two ends of the sample to be tested are respectively fixedly connected to the first clamping part and the second clamping part; usually, the sample to be tested can be pretreated so that the sample to be tested can obtain a set initial measurement state; for example, it can be Place the sling or high-altitude safety belt in the air with a relative humidity of less than 10% for more than 24 hours, then place it in an environment with a temperature of 20°C and a relative humidity of 65% for more than 72 hours, and then cut a certain length of test sample. For example 4000mm;
[0096] (2) Adjust the distance between the first clamping part and t...
