How can I know the quality of the office chair? How can we know that the office chair has no safety hazards? How can I know if there is a problem with the office chair? At this time, you need to test the reliability of the office chair by pushing the back!
So what is the push back test of an office chair?
The push-back test relies on the push-back test machine to apply a certain force to the back of the chair to squeeze the office chair back. Its main purpose is to test the ability of each part of the office chair to withstand squeezing.
In addition, according to the applied force, we divide the office chair backrest test into two types: destructive test and functional test.
The force applied for the destructive test was 138 kg and the duration was 1 minute. If all parts of the office chair are severely deformed, damaged or broken after the test, the test fails.
The force applied by the functional test is 92 kg and the duration is 1 minute. If all parts of the office chair are deformed, damaged or broken after the test, the test will fail.
In this way, the quality and safety issues of office chairs can be well distinguished, and the hidden dangers of office chairs can be avoided to a large extent!
