IS 15801 vs ISO 15874: BIS Rules for PPR Pipe Imports

An Indian distributor opens a quotation for PP-R pipe from a Chinese plant. The folder holds ISO 15874 and DIN 8077 test reports, an ISO 9001 certificate and a German lab report. The purchase manager asks one question before he signs: does any of that satisfy BIS, and will the container clear without an ISI […]
PPR Pipe Fire Rating: Euroclass, B2 and GCC Codes

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.

PPR Pipe Installation Method Statement: Clause Template

The package comes back with one line against it. “Method statement not specific to the proposed system. Resubmit.” Nine sections, the right sequence of work, the right PPE list, returned inside a day. The reviewer wanted a number he could check, and the jointing clause said “fuse as per manufacturer’s recommendation”. A PP-R installation method […]
PPR Pipe Brands: How to Tell a Real One From a Relabel

A quotation lands on your desk naming one of the PPR pipe brands you keep seeing on “top 10” lists, and you have never seen that name printed on a length of pipe. You run a distribution yard, moving a container of PP-R a quarter, and the price sits under your current line. What you […]
