When the relevant EN dealing with general requirements, such as General requirements for external systems and components (CEN/TC 164/WG 1) Materials in contact with water (CEN/TC 164/WG 3) and Structural design (CEN/TC 164/165/JWG 1) are adopted, the present standard shall be revised, wh
35、ere appropriate, in order to ensure that these requirements comply with the relevant ENs. To the present standard, are attached: Annex A (informative): Notation of main parameters; Annex B (informative): Span pipe calculations. 1 Scope This European Standard specifies common requirements for the fol

In a homogenous environment, they perform satisfactorily. However where a heterogenous environment exists special arrangements may be necessary and agreed between purchaser and manufacturer. In some cases, the environment may require specific arrangements for example:
