AS 2118.8-1997 Automatic fire sprinkler systems, Part 8: Minor modifications
Standards Australia
Reconfirmed by: AS 2118.8-1997 Rec:2013 Automatic fire sprinkler systems, Part 8: Minor modifications
This Standard is the result of a consensus among representatives on the Joint Committee to produce it as an Australian Standard.
The objective of this Standard is to provide requirements to apply when an existing sprinkler system of light or ordinary hazard classification is to be subjected to minor modifications such as the removal, alteration or addition of sprinklers, or the modification or addition of ranges and distribution pipes of limited size.
Product and installation Standards are kept separate. The AS 2118 series, Automatic fire sprinkler systems, and the related series AS 4118, Fire sprinkler systems, comprise the following:

Most fire sprinkler systems will undergo minor modifications, especially ordinary hazard systems installed in shopping centres and multistoried office blocks where ongoing changes in tenancy require that changes in the location of walls, partitions, lights, or to the decor require the relocation, addition or deletion of sprinkler heads. It would be uneconomical for the installation design drawings and hydraulic calculations to be fully revised when minor modifications can be done effectively by site personnel possessing a knowledge of the original system design criteria and of the requirements and limitations as set out in this Standard.
This Standard assumes that any existing system intended to be modified, as distinct from the proposed modification, fully complies with the requirements of the Standard to which it was originally designed and installed. In circumstances where the original system does not comply with the appropriate design and installation Standard, the areas which do not comply together with the proposed modifications should be approved by the appropriate regulatory authority prior to commencement of the proposed modification work.

First published as AS 2118.8-1997.
This Standard sets out the requirements and limitations pertaining to minor modifications which may be required to existing light hazard and ordinary hazard automatic sprinkler systems only. Modifications to high hazard, wall-wetting, deluge, residential and domestic systems are subject to design analysis before work commences and are not covered by this Standard.
