Overview

EN ISO 15874-1:2013 - Plastics piping systems for hot and cold water installations - Polypropylene (PP) - Part 1: General defines the general requirements and framework for polypropylene (PP) piping systems used inside buildings for hot and cold water distribution and heating systems. It applies to PP pipes, fittings, joints and joints to other plastic or non‑plastic components under the design pressures and temperatures defined by the applicable classes of application. The part also specifies test parameters for referenced test methods and sets out terms, definitions and system performance requirements.

Key topics and technical requirements

• Scope and applicability: Covers domestic water systems (whether or not intended for human consumption) and heating systems within buildings; users must consider relevant national regulations on potable water.
• Classes of application: Establishes a range of service conditions (classes) relating to temperature and design pressure that determine suitable PP materials and components.
• Material requirements: General material criteria for PP, including the inclusion of PP‑RCT in the 2013 edition; addresses material influence on water quality and reprocessable material.
• Geometrical and dimensional definitions: Standardizes terms such as nominal size (DN/DN/OD), wall thickness, outside diameter, ovality and pipe series (S), aligned with ISO 4065 and ISO 472 vocabulary.
• System performance: Defines performance expectations for pipes, fittings and joints to ensure fitness for purpose when combined with Parts 2, 3 and 5.
• Test parameters: Specifies test parameters used by the other parts of ISO 15874 (e.g., test conditions and durations) rather than full test procedures.
• Normative references: Cross‑references ISO 15874‑2 (Pipes), ISO 15874‑3 (Fittings), ISO 15874‑5 (Fitness for purpose) and ISO/TS 15874‑7 (Conformity guidance), plus general plastics standards (ISO 472, ISO 1043‑1, ISO 4065).

Applications

EN ISO 15874-1:2013 is intended for use in:

• Domestic hot and cold water distribution and internal plumbing systems.
• Building heating systems (hydronic distribution using PP piping).
• System specification and design, where designers select appropriate class of application and material.
• Manufacturing and quality control of PP pipes, fittings and jointing components.
• Testing, assessment and conformity activities carried out by laboratories and certification bodies.

Who uses this standard

• Building services engineers and piping system designers
• Manufacturers of polypropylene piping systems and fittings
• Installers and contractors specifying compliant pipework
• Test laboratories, certification bodies and regulators
• Procurement specialists and specifiers who must meet national codes
