A PP-R submittal comes back with one line circled: fire rating. The importer who quoted the job must now answer a question the pipe standard never asked and the certificate folder does not contain.<\/p>\n

The short version is this. Polypropylene burns. Under EN 13501-1:2018 a pipe carries a reaction-to-fire class only where a specific product has a classification report behind it, and a product with no report sits in class F. The class B2 that suppliers quote comes from DIN 4102-1:1998-05, a German national standard, and it does not convert into a Euroclass. Neither number decides whether the pipe is allowed on the job. Two other things do: the sealed penetration where the pipe crosses a rated wall, and the system the pipe serves.<\/p>\n

That second point is the boundary page one misses. PP-R carrying potable hot and cold water is plumbing with a firestopping detail. PP-R inside fire-fighting piping is settled by listing, not by fire class.<\/p>\n\n
