| BSI | 2020 | 32 |
This European Standard specifies requirements and test methods for rain caps that are used as components, subject to flue gas, in order to prevent rain entry into the chimneys. Rain caps already tested together with system chimney products or other chimney components, e.g. terminals, are not covered by this standard. Rain caps incorporating a bird guard are also included. It also specifies the requirements for marking, manufacturers’ instruction, product information and evaluation of conformity.
