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 articles1 the test specimen should be representative of the production model.
In the case of designs not catered for in the test procedures, the test should be carried out as far as possible as described, and deviations from the test procedure recorded in the test report.
Tests carried out according to this International Standard are intended to demonstrate the ability of the item to give satisfac. tory service in its intended environment. It should be understood that such tests do not ensure that structural failure will not eventually occur as a result of habitual misuse or after an excessively long period of service, or more than occasional use by persons weighing more than 100 kg.

For the purposes of this International Standard, the following definitions apply.
3.1 Strength tests (see 7.1 to 7.4 and 7.7 to 7.13)
3.1.1 static tests: Test consisting of heavy loads being applied a few times to ensure that the furniture has sufficient strength to perform its function under the highest levels of loading that might reasonably be expected to occur.
3.1.2 impact tests: Test to assess the strength of the artide under the rapid rates of loading that occasionaJly occur.
