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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.

Fire protection — Automatic sprinkler systems —
Part 10:
Requirements and test methods for domestic sprinklers
1 Scope
This part of ISO 6182 specifies performance requirements, test methods and marking requirements for
domestic sprinklers.
These sprinklers are intended to provide control of fires in domestic occupancies, to prevent flashover (total
involvement) in the room of fire origin and to improve the probability for successful escape or evacuation of
the occupants.

---------------------- Page: 9 ----------------------
DIS ISO 6182-10:2012(E)
Example The bubble in each glass bulb shall be examined at room ambient temperature. The sprinkler shall
then be heated in a circulating air oven or liquid bath to 5°C below the minimum operating temperature range of the
sprinkler. The bubble shall then be examined to determine the bubble size has been reduced in accordance with the glass
bulb manufacturer's specifications. After cooling, the bubble size shall again be examined to determine the bubble
returned to the original size within the tolerance allowed by the glass bulb manufacturer.
5 Product assembly
5.1 General
All domestic sprinklers shall be designed and manufactured in such a way that they cannot be readily adjusted,
dismantled or reassembled.
NOTE This requirement does not apply to units intended for assembly/adjustment on site, e.g. combinations of
sprinkler and escutcheons or the assembly of the cover plate to concealed sprinklers.
5.2 Dynamic O-ring seals
The closure of the water seat shall not be achieved by the use of a dynamic O-ring or similar seal (an O-ring
or similar seal that moves during operation or is in contact with a component that moves during operation).
5.3 Dry Sprinklers
When installed with the intended fittings specified in the manufacturer’s installation instructions, dry sprinklers
installed in dry systems shall be constructed to minimize the potential to accumulate water, scale, and
sediment on the sprinkler inlet. The sprinkler inlet shall also be constructed not to significantly obstruct the
flow path.
5.4 Dezincification
Consideration should be given to the possible weakening of brass components of the sprinkler due to
dezincification processes when the components are in constant contact with water. Annex D contains a
procedure to prove that the selected materials are suitable.
NOTE Caution should be exercised when using a piping system that exchanges its water inside more frequently,
and/or, when using non-corrosive piping material such as resin piping material.
5.5 Stainless steel components
Consideration should be given to the possible weakening of stainless steel components of the sprinkler due to
the environment of installation. Annex E contains a procedure to prove that the selected materials are
suitable.

with the horizontal- and vertical-surface water-distribution requirements described in 6.4.2.2 and 6.4.2.3.
6.4.2.2 Horizontal surfaces
When installed in accordance with the manufacturer's design and installation instructions and tested as
described in 7.5.1.1 through 7.5.1.4, a sprinkler shall distribute water over a horizontal surface such that the
discharge density collected in any single 300 mm  300 mm collection pan within the design area shall be at
least 0,8 mm/min, except that
a) no more than four collection pans in each quadrant shall be allowed to be at least 0,6 mm/min for upright
and pendent sprinklers; and
b) no more than eight collection pans shall be allowed to be at least 0,6 mm/min for each half (split along the

6.4.2.3 Vertical surfaces
When installed in accordance with the design and installation instructions and tested as described in 7.5.2, a
sprinkler shall distribute water over vertical surfaces as follows
a) Walls within the coverage area shall be wetted to at least 700 mm of the ceiling with one sprinkler
operating at the specified design flow rate.
b) For square coverage areas, each wall within the coverage area shall be wetted with at least 5 % of the
