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).
Any trade name used in this document is information given for the convenience of users and does not

expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see www .iso

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 6182-4:1993), which has been technically
revised.

Fire protection — Automatic sprinkler systems —
Part 4:
Requirements and test methods for quick opening devices
1 Scope
This document specifies the performance and testing requirements for accelerators used with dry pipe
valves in fire protection systems to hasten the operation of the valves when one or more sprinklers
operate.
2 Normative references
The following documents are referred to in the text in such a way that some or all of their content
constitutes requirements of this document. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any amendments) applies.
ISO 49, Malleable cast iron fittings threaded to ISO 7-1
ISO 898-1, Mechanical properties of fasteners made of carbon steel and alloy steel — Part 1: Bolts, screws
and studs with specified property classes — Coarse thread and fine pitch thread
ISO 898-2, Mechanical properties of fasteners made of carbon steel and alloy steel — Part 2: Nuts with
specified property classes — Coarse thread and fine pitch thread
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:
— IEC Electropedia: available at http: //www .electropedia .org/
— ISO Online browsing platform: available at http: //www .iso .org/obp
3.1
accelerator
quick-opening device which hastens the operation of a dry pipe valve using mechanical means other
than by reducing installation pipework pressure
Note 1 to entry: For the purposes of this document, the term accelerator refers to an accelerator and any (internal
or external) antiflooding device (3.2).
3.2
antiflooding device
device intended to prohibit excessive water or other foreign matter from entering any relevant part or
parts of the accelerator where this might prevent subsequent operation
3.3
corrosion-resistant material
metallic material of bronze, brass, copper-nickel alloys metal, austenitic stainless steel, or equivalent,
or plastic material conforming with the requirements of this document

3.4
rated working pressures
maximum service pressure at which an accelerator is intended to operate
3.5
service pressure
static water pressure at the inlet to a dry pipe valve when the accelerator and the dry pipe valve are in
the ready condition
3.6
holding chamber
chamber pressurized with system air pressure which actuates an accelerator upon a sufficient rate of
loss of system air pressure
4 Requirements
4.1 Rated working pressure
The rated working pressure shall be not less than 1,2 MPa (12 bar).
4.2 Leakage test (see 6.4)
4.2.1 There shall be no leakage of an accelerator when a pneumatic pressure of 0,7 MPa (7 bar) is
applied for 1 min in accordance with 6.4.1.
4.2.2 There shall be no leakage of an accelerator when an internal hydrostatic pressure of twice the
rated working pressure is applied for 5 min when tested in accordance with 6.4.2.
4.3 Bodies and covers
4.3.1 Accelerator bodies and covers shall be made of a material having a corrosion resistance at least
equivalent to cast iron.
4.3.2 The dimension of all connections shall conform with the applicable requirements of international
standards. If international standards are not applicable, national standards shall be permitted to be used.
4.3.3 Non-metallic materials, other than gaskets and pipe seals, or metals with a melting point of
