适用范围：This European Standard specifies mechanical test methods for determining the stability, strength anddurability of office work chairs.This European Standard does not specify 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, aswell as misuse that might reasonably be expected to occur.The tests are designed to evaluate properties without regard to materials, design/construction ormanufacturing processes.The test results are only valid for the article tested. When the test results are intended to be applied to othersimilar articles, it is important that the 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 givesatisfactory service in its intended environment. The safety requirements are specified in EN 1335-2 andadditional loads, masses and cycles for functional tests can be found in Annex C (informative).The tests have been developed for units/components that have not been in use. However, when properlyjustified, they may be used for fault investigation.Assessment of ageing and degradation is not included. The tests are not intended to assess the durability ofupholstery, i.e. filling materials and covers.Data are given for the design of seat-loading pads in Annex A (normative) and for the design of stabilityloadingpad in Annex B (normative).
