Thermoplastics pipe and fitting systems for hot and cold water for domestic purposes and heating installations in buildings - Specification for polybutylene (PB) pipe and associated fittings Ingestion-build-58320 11 helps in the testing1 Scope This part of BS 7291 specifies general requirements and methods of test for polybutylene (PB) pipe and fitting systems intended for use within buildings for the conveyance of cold water, including drinking water, and heated water for use in domestic hot and cold water distribution and heating installations. These requirements supplement the general requirements in BS 72911, which are also applicable. NOTE 1 Before reading this part, it is
