Therefore, the purchasers of accessories tested to this European Standard, must ensure that all their requirements are met.NOTE This European Standard does not invalidate existing approvals of products achieved on the basis of national sta

However, products approved according to such national standards or specifications cannot directly claim approval to this European Standard. It may be possible, subject to agreement between supplier and purchaser,

Any such additional testing that is part of a seque

A range of optional, additional tests is provided to meet the varying climatic needs and thes
