Overview

ISO 6182-11:2019 - Fire protection - Automatic sprinkler systems - Part 11: Requirements and test methods for pipe hangers establishes construction, performance, test and marking requirements for typical types of pipe hangers used in sprinkler systems. The standard defines terminology, materials, rod sizes, material thickness limits, product consistency (manufacturer quality control), performance criteria and specified test methods to verify strength, coating thickness and vibration resistance.

Key topics and technical requirements

• Scope & purpose: Specifies construction requirements, performance requirements, test methods and marking for pipe hangers used in automatic sprinkler systems.
• Definitions: Detailed terminology for hanger and attachment types (e.g., band/loop hangers, clevis, clevis hanger, beam clamp, riser clamp, ceiling flange, cast‑in insert, expansion and undercut anchors).
• Materials: Hangers shall be made of ferrous or other non‑heat‑sensitive materials (see clause 5.1).
• Rod sizes: Nominal rod diameters are defined (Table 1) and rolled‑thread root diameters are addressed (clauses 5.2.x).
• Material thickness: Minimum uncoated flat steel thickness permitted for certain hangers is given (example: unprotected flat steel ≥ 3 mm acceptable for some clevis and band hangers when ≥ 25 mm wide and meeting strength criteria) (clause 6.1).
• Performance requirements: Includes elongation and pull requirements, criteria for concrete inserts and vibration resistance (clause 7).
• Test methods:
  • Metallic coating thickness: gravimetric, X‑ray spectrometry, magnetic methods (ISO 1460, ASTM B568 referenced) (clause 8.1).
  • Mechanical tests for rods, pipe attachments and building attachment components (clauses 8.2–8.3).
  • Vibration tests (clause 8.4).
• Marking: Requirements for hanger and factory marking to support traceability and compliance (clause 9).
• Normative references: Includes ISO 1460, ISO 2064, ISO 2178, ISO 3575, ISO 4998 and ASTM B568 among others.

Practical applications and users

ISO 6182-11:2019 is used to ensure reliable, safe and durable supports for sprinkler piping. Typical users include:

• Manufacturers of pipe hangers, clamps, rods and building attachment components for sprinkler systems.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/patents).

This document was prepared by Technical Committee ISO/TC 21, Equipment for fire protection and fire
fighting, Subcommittee SC 5, Fixed firefighting systems using water.
This second edition cancels and replaces the first edition (ISO 6182-11:2003), which has been technically
revised.
The main changes compared to the previous edition are as follows:
— The seismic requirements and testing have been removed from this document and will be addressed
in a separate standard.
