Review of Australian Standards To keep abreast of progress in industry, Australian Standards are subject

to periodic review and are kept up to date by the issue of amendments or new editi ons as necessary It is important therefore that Standards users ensure that they are in possession of the latest editi on, and any amendments thereto.

Full detail s of all Australian Standards and related publi cati ons wil l be found in the Standards Australi a Catalogue of Publications; this information is supplemented each month by the magazine ‘The Australi an Standard’, which subscribing members receive, and which gives detail s of new publications, new edit ions and amendments, and of withdrawn Standards.

Suggesti ons for improvements to Australian Standards, addressed to the head off ice of Standards Australi a, are welcomed Notif ication of any inaccuracy or ambiguit y found in an Australi an Standard should be made without delay in order that the matter may be investigated and appropriate action taken.

This standard was issued in draft form for comment as DR 92189.

in these losses due to the difference in static pressure between the level

of the sprinkler in the top storey shall be shown as x in Column 7 of Figure 2.1

(D) For high hazard systems using the piping arrangements of Tables 11.4.2.2(A) to 11.4.2.2(C) in AS 2118.1, the total pressure loss

in the various runs of distribution piping between each design point and the control assembly shall be related to the residual pressure available from the water supply when tested under the appropriate flow rate The pressure required at the design point and the static head loss due to the height of the highest sprinkler, in the particular array, above the control assembly shall be included in these calculations
