This European Standard does not specify
21、type approval tests for chair components. The tests are designed to be applied to an article of furniture that is fully assembled and ready for use. The tests consist of the application, to various parts of the item, of forces simulating normal functional use, as well as misuse that might reasonably

The test results are only valid for the article tested. When the test results are intended to be applied to other similar articles, it is important that t
23、he test specimen be representative of the production model. Tests carried out according to this standard are intended to demonstrate the ability of the item to give satisfactory service in its intended environment. The safety requirements are specified in EN 1335-2 and additional loads, masses and c
