Introduction
Domestic sprinklers are primarily intended for use in dwelling units. These sprinklers are specifically
designed to discharge water in a manner that is expected to prevent flashover within the compartment
of fire origin and improve the chance for occupants to escape or be evacuated in dwelling units such as
homes, apartments, condominiums, and hotel sleeping rooms. While domestic sprinklers are designed
to protect against injury and loss of life, the use of these sprinklers has demonstrated the ability to
provide property protection as well. Other types of sprinklers are addressed in the separate parts of the
ISO 6182 series.
These sprinklers characteristically have a very flat spray pattern. This allows for the sprinklers to wet the
walls of the compartment which reduces the potential for the vertical surfaces to substantially contribute
to a flashover condition. These sprinklers also discharge water in a manner that provides a relatively
uniform distribution of water on the protected floor area. Obstructions can pose a significant obstacle
to domestic sprinklers because of the flat spray pattern. Domestic sprinkler installation guidelines
need to account for the flat spray pattern when considering the distances between obstructions and the
sprinkler.
Product standards, such as this one, can provide a minimum level of safety in the built environment as
well as a level of quality to the products on the market.

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.

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.

3,4 MPa (34 bar) for at least 2 s.
4.3 Glass bulb integrity test

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.
