32、 EN 16475-7:2016-05 EN 16475-7:2016 (E) 7 1 Scope This European Standard specifies requirements and test methods for rain caps that are used as components, subject to flue gas, in order to protect against rain entry into the chimney flues. Rain caps which are part of components of a system chimney o

33、r other components of a chimney such as terminals, are not covered by this European Standard. It also specifies the requirements for marking, manufacturers instruction, product information and attestation and verification of constancy of performance (AVCP). NOTE Rain caps according to this standard

34、are suitable for both dry and wet chimney applications. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
