NF EN 29142

<p>ISO 9142:2003 describes laboratory ageing conditions under which adhesive joints may be exposed to various environmental influences -- climatic or chemical -- for the purpose of assessing the effects of such influences on certain properties.</p> <p>The ageing conditions are applicable to bonded assemblies and may be used to constitute a set of tests for the evaluation of an adhesive.</p> <p>The results obtained using the procedures described in this International Standard are not necessarily applicable to the determination of the service life of a bonded assembly because there is no direct relation between the test results and the behaviour of a bonded assembly over a period of time under service conditions. However, for certain specific applications, experience with the procedures may enable a correlation to be established.</p>
