SIST EN ISO 15876-2:2017 PDF

Overview

EN ISO 15876-2:2017 - Plastics piping systems for hot and cold water installations - Polybutene (PB) - Part 2: Pipes - is the CEN-adopted ISO system standard that specifies the characteristics and test parameters for polybutene-1 (PB-1) pipes used in building hot and cold water and heating systems. The document applies to PB pipes (including homopolymer PB-H and random copolymer PB-R), with or without thin barrier layers, and covers a range of application classes, design pressures and temperatures referenced to ISO 15876‑1. It is intended for use where water is conveyed within buildings, whether or not for human consumption.

Key topics

• Scope and applicability
  • Defines intended uses (domestic water and heating systems) and limits tied to ISO 15876‑1 (design pressures/temperatures).
  • Notes purchaser/specifier responsibility to select appropriate application class and comply with national regulations.
• Material and product requirements
  • Material designation (polybutene/PB) and distinction between PB-H and PB-R.
  • Applicability to pipes with or without barrier layers; design stress met by base polymer for thin barriers.
• Geometrical, mechanical and physical characteristics
  • Requirements for dimensions, wall thickness tolerances and appearance.
  • Mechanical performance and long-term hydrostatic strength considerations.
• Test parameters and methods
  • Specifies test parameters for referenced methods, including: ISO 1133-1 (MFR/MVR), ISO 1167 (internal pressure resistance), ISO 2505 (longitudinal reversion), ISO 3126 (dimensions), ISO 7686 (opacity), ISO 9080 (long-term hydrostatic strength).
• Marking and performance
  • Minimum marking requirements and performance criteria to ensure fitness for purpose within the system standard framework.

Applications

Who uses EN ISO 15876-2:2017:

• Manufacturers of PB pipes and multilayer PB products for domestic and heating systems.
• System designers and specifiers selecting pipe dimension classes, application classes and design pressures/temperatures.
• Installers and contractors requiring product conformity and marking information.
• Testing laboratories and conformity assessment bodies applying the specified test parameters.
• Authorities and consultants assessing compliance with national regulations and building codes.

Practical value:

• Ensures consistent quality and predictable long-term performance of PB piping in potable water and heating installations.
• Facilitates product selection and compliance checks across CEN/ISO markets.
