Foreword

GB/T 28799 "Heat-resistant Polyethylene (PE-RT) Piping System for Hot and Cold Water" is divided into the following parts.

---Part 1.General Provisions;

---Part 2.Pipes;

---Part 3.Pipe fittings;

---Part 5.System applicability.

This part is Part 5 of GB/T 28799.

This section was drafted in accordance with the rules given in GB/T 1.1-2009.

This part adopts the redrafting method to refer to ISO 22391-5.2009 "Heat-resistant polyethylene for plastic piping systems for cold and hot water (PE-RT)

Part 5.System Applicability", the degree of consistency with ISO 22391-5.2009 is not equivalent.
