Full title and description

St ISO 17885-2021 — Plastics piping systems — Mechanical fittings for pressure piping systems — Specifications. This International Standard specifies requirements and test methods for mechanical fittings used to join plastic pressure piping systems, including transition fittings to metal pipes, for applications such as gaseous fuels, drinking water, pressure drainage/sewerage, irrigation and industrial uses.

Abstract

The standard defines performance, design and testing requirements for mechanical fittings intended for plastic pressure piping systems. It establishes applicable materials, dimensional and mechanical criteria, test procedures and marking/identification expectations. The document excludes flanges and does not apply to mechanical fittings specifically intended for hot/cold water systems inside buildings or for district heating.

Scope

ISO 17885:2021 applies to mechanical fittings intended to join plastic pressure piping systems, including transition fittings to metal pipes, for supply of gaseous fuels, supply of water for human consumption (including raw water prior to treatment), underground drainage and sewerage under pressure, irrigation and industrial applications. The standard is applicable only for fittings with operating-temperature and pressure limits indicated in the relevant system standards; flanges are excluded. Mechanical fittings for hot and cold water systems inside buildings and for district heating applications are not covered. Annex A lists system standards for which these mechanical fittings can be used.

Key topics and requirements

• Design and dimensional requirements for mechanical fittings to ensure interchangeability and correct assembly.
• Material and construction criteria addressing durability, corrosion resistance and compatibility with plastic pipe materials.
• Performance test methods, including pressure, leakage and mechanical strength tests under specified temperature/pressure conditions.
• Requirements for transition fittings to metal pipes (where applicable) and restrictions on applications and temperature/pressure ranges.
• Marking, identification and documentation requirements for traceability and safe installation.
• Exclusions and application limits (e.g., flanges; fittings for building hot/cold water and district heating are not covered).

Typical use and users

Manufacturers of mechanical fittings and plastic pipe systems, product designers, testing and certification bodies, quality assurance engineers, procurement/specification authors, utilities and contractors involved in installation of pressure piping for gas, potable water, irrigation and industrial systems. Regulators and standards committees reference the standard when specifying acceptable mechanical fitting performance.

Related standards

ISO 17885:2021 replaces ISO 17885:2015 (and its 2016 amendment). Related documents include system standards for plastic pipes and piping systems referenced in Annex A of ISO 17885 (national and sectoral pipe standards that set applicable operating temperatures and pressures). National adoptions/identical publications (for example BS ISO and ÖNORM versions) exist.

FAQ

Q: What is this standard?

A: ISO 17885:2021 is an international standard that specifies requirements and test methods for mechanical fittings used in plastic pressure piping systems, including transition fittings to metal pipes for various applications such as gas, potable water, irrigation and industrial services.

Q: What does it cover?

A: It covers design, material, performance and testing requirements for mechanical fittings, plus marking and documentation. It excludes flanges and fittings specifically for hot/cold building water systems and district heating. Applicability is bounded by the operating-temperature and pressure limits given in the relevant system standards.

Q: Who typically uses it?

A: Manufacturers, test laboratories, conformity assessment bodies, engineering and installation contractors, utilities, specifications authors and standards committees working with plastic pressure piping systems.

Q: Is it current or superseded?

A: The 2021 edition (Edition 2) is the current published edition and it replaces the 2015 edition (and its 2016 amendment). Users should confirm national adoptions or corrigenda that may apply in their country.

Q: Is it part of a series?

A: It is part of the body of ISO standards addressing plastics piping systems (ISO/TC 138 work) and is referenced alongside other ISO and national standards that specify pipe materials, system requirements and application-specific limits; Annex A of ISO 17885 lists relevant system standards.
