This standard specifies test methods for determining the stability, strength and durability of office work chairs. This 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 dimensions in the tests are applicable to office work chairs intended for adult persons. 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 be expected to occur. The tests are designed to evaluate properties without regard to materials, design/construction or manufacturing processes. The test results are only valid for the article tested. When the test results are intended to be applied to other similar articles, the test specimen should 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 tests have been developed for units/components that have not been in use. However, when properly justified, they may be used for fault investigation. This standard does not give any product requirements. These should be specified in a requirements document. If this is not available, possible forces and cycles are suggested in Annex A (informative). These forces and cycles may be used for adults regardless of their weight and number of working hours. Assessment of ageing and degradation is not included. The tests are not intended to assess the durability of upholstery, i.e. filling materials and covers. Annex B (normative) includes data for the design of seat loading pads. Annex C (normative) includes data for the design of stability loading pad.
