About The Operating Requirements For Office Chair Durability Testers
Feb 14, 2022
In order to ensure that the mechanical equipment is always in a good technical state and can be put into operation at any time, reduce mechanical wear, prolong the service life of the machinery, reduce the cost of mechanical operation and maintenance, and ensure safe production, it must be strictly operated. So how should the office chair durability tester operate ?
Operating requirements:
1. Test environment, the temperature of the standard test environment is 15°-25°C, and the relative humidity is 40%-70%.
2. Loading requirements. During the strength test, the acceleration rate should be as slow as possible to ensure that the additional load can be negligibled. During the durability test, the acceleration rate should be slow to ensure that the specimen does not have dynamic heating.
3. Test steps.
① The test specimens shall be tested in accordance with the test steps specified in this standard. The durability test can be carried out on different test specimens, and the strength test shall be carried out on the same test specimen.
②. If the test piece does not conform to the test procedures due to the special structure, the test should be carried out according to the test procedures specified in this standard as much as possible, and the relevant differences should be recorded in the test report.
③. To determine the service life of the office chair durability tester, the test should pass each test level step by step until the test piece is destroyed.
④. If you want to check whether the mechanical properties of office chair durability tester meet the specified requirements, the test can be carried out directly according to the corresponding level of the test.
