20、cument specifies requirements relating to the construction, performance and methods of testing for mechanical filters for the removal of suspended matter in drinking water installations inside buildings. It applies to filters with a filtration rating from 1 m up to less than 80 m and which are inten
21、ded for use in systems with a minimum pressure rating of PN 6, connections between DN 15 and DN 100 and service temperature of less than 30 C. This document is applicable to back-washable filters, integral filters and those designed for replaceable cartridges. It only concerns units that are permane
22、ntly connected to the mains supply at point of entry or point of use. Part 1 of this standard (EN 13443-1) is a separate document and deals with filters with a particle rating between 80 m and 150 m. 2 Normative references The following referenced documents are indispensable for the application of t
