Full title and description

Fire protection — Automatic sprinkler systems — Part 17: Requirements and test methods for pressure reducing valves. This International Standard specifies performance requirements, marking and methods of test for pressure reducing valves (both pilot‑operated and direct‑acting) intended to reduce downstream water pressure in piping for water‑based fire protection systems.

Abstract

This document defines the required characteristics, constructional features and test procedures for pressure reducing valves used in automatic sprinkler systems. It covers nominal sizes, connection requirements, rated working pressure, materials and strength, leakage and durability tests, production testing and marking. It excludes performance requirements for other auxiliary components or attachments to the pressure reducing valve itself.

Scope

The standard applies to pressure reducing valves intended to reduce downstream water pressure in the piping of water‑based fire protection systems. It covers both pilot‑operated and direct‑acting pressure reducing valves and specifies nominal sizes, connection types, rated working pressure, materials, constructional and maintenance provisions, performance limits (leakage and deformation), and required type and production tests. It does not set requirements for other auxiliary components or attachments to the pressure reducing valve.

Key topics and requirements

• Nominal sizes and tolerances (sizes specified from DN40 up to DN300 and related tolerances).
• Connection types and dimensions to be compatible with relevant international or national standards.
• Rated working pressure — valves shall be rated for not less than 1.2 MPa (12 bar) unless specifically marked otherwise for lower pressures.
• Materials and corrosion resistance — body and cover materials equivalent to cast iron or better; restrictions on non‑metallic body parts.
• Strength/hydrostatic testing — body assembly tests (e.g., withstand 4× rated working pressure for specified time) and diaphragm strength tests.
• Access and serviceability — design for maintenance and inline servicing; parts intended for servicing should be reassembled without incorrect installation or provide visual indication if misassembled.
• Leakage, deformation and durability tests — static leakage limits, operational cycle testing and verification of sealing assemblies and springs/diaphragms.
• Production testing and quality control requirements and marking/identification information for traceability.

These requirements are presented with associated test methods and acceptance criteria in the standard's clauses and test sections.

Typical use and users

Used by manufacturers of pressure reducing valves and sprinkler system components, product test laboratories, certification bodies, fire protection system designers, consulting engineers, installers and authorities having jurisdiction responsible for specifying, installing, testing and approving automatic sprinkler systems and their components. The standard provides criteria for design verification, type testing and production control.

Related standards

ISO 6182 is a multipart series on automatic sprinkler systems. Relevant related parts include (examples): ISO 6182‑2 (requirements and test methods for alarm and check valves, water motor alarms, retard devices and accelerators), ISO 6182‑12 (grooved‑end components for steel pipe systems), and ISO 6182‑16 (requirements and test methods for fire pump relief valves). Users should consult the full ISO 6182 series and national/regional regulations for complementary requirements.

FAQ

Q: What is this standard?

A: ISO 6182‑17:2020 is an International Standard that specifies performance requirements and test methods for pressure reducing valves used in water‑based automatic sprinkler systems (pilot‑operated and direct‑acting types).

Q: What does it cover?

A: It covers nominal sizes and tolerances, connection and material requirements, rated working pressure, strength and hydrostatic tests, leakage and durability testing, production testing and marking. It does not cover auxiliary components or attachments that are not integral to the pressure reducing valve’s basic performance.

Q: Who typically uses it?

A: Manufacturers, test laboratories, certification bodies, fire protection designers and installers, and regulatory/approval authorities use the standard for product development, type testing, production control and conformity assessment.

Q: Is it current or superseded?

A: ISO 6182‑17:2020 is the first published edition of this part (2020). Users should check the ISO catalogue or national standards bodies for any amendments or revisions since 2020 to confirm current status.

Q: Is it part of a series?

A: Yes — it is one part of the multipart ISO 6182 series covering automatic sprinkler systems and associated components; other parts address different valves, fittings and components used in sprinkler systems.

Q: What are the key keywords?

A: Pressure reducing valve, sprinkler system, test methods, performance requirements, rated working pressure, hydrostatic strength, durability, pilot‑operated, direct‑acting.
