2.4.12.1.4 Component and materials compatibility

The Approval Body shall examine the design of the product and make an assessment, using well-established principles, of the suitability of materials in contact. It is impossible to prescribe all the possible risk areas but these include the possibility of bi-metallic corrosion, the effects of over-painting etc.

2.4.12.2 Method of assessing and judging

2.4.12.2.1 Materials/products covered by a standard

When the material/product (e.g. metal parts or other components) meet the relevant requirements given in the standards referenced they are considered being durable.

2.4.12.2.2 Materials/products not covered by a standard

Basically, to achieve a positive assessment of durability no change in the assessed property is allowed. However, as repeatability and reproducibility of most of the test methods to determine relevant properties are unknown a deviation of the mean values of the property assessed before and after exposure of not more than 15% may be taken as a positive result of the durability assessment.

In case of high scatter of the test results an alternative is to take a statistical approach, using an appropriate high number of test specimens. This approach may be used to demonstrate that the mean value of the property after exposure does not deviate from the mean value before exposure.
