Describes conditions under which adhesive joints may be exposed to various climatic or chemical influences for the purpose of assessing the effects of such influences on certain properties. They are not necessarily applicable to the determination of the service life of a bonded assembly. The principle consists in defining the ageing conditions that relate most closely to the application for the adhesive by reference to the preferred conditions set out in annex A to annex F. These conditions are single-variable, multi-variable, cyclic, change of heat, cold (thermal shock), humidity, dryness, immersion in water or salt solutions, exposure to chemical attack and combinations of these.
