Review of Australian Standards. To keep abreast of progress in
industry, Australian Standards are subjectto periodic review and
are kept up to date by the issue of amendments or new editions as
necessary. It isimportant therefore that Standards users ensure
that they are in possession of the latest ed ition, and
anyamendments thereto.Full details of all Australian Standards and
related publications will be found in the Standards
AustraliaCatalogue of Publications; this information is
supplemented each month by the magazine The AustralianStandard,
which subscribing members receive, and which gives details of new
publications, new editionsand amendments, and of withdrawn
Standards.Suggestions for improvements to Australian Standards,

which sprinkler installations and fire hydrants are
directlyconnected shall be reticulated through the building in the
form of ring mains (one ring foreach pressure zone). Piping shall
be sized by hydraulic calculation (see AS 2118.1) subjectto the
following minimum pipe diameters (a) in buildings not exceeding 25
m effective height . . . . . . . . . . . . . . . . . . DN 100(b) in
buildings exceeding 25 m effective height . . . . . . . . . . . . .
. . . . . . . . DN 150.The vertical portions of the ring main pipes
shall be located within separate fire-rated exits(stairways) or
fire-rated riser shafts. In the case of adjoining pressure zones,
which do notshare a common horizontal cross connection, each cross
connection shall be located withinits own pressure zone.2.6.2

APPENDIX D
SYSTEM RESISTANCE CURVE FOR COMBINEDSPRINKLER AND HYDRANT
SYSTEMS
(Normative)
D1 SCOPE This Appendix sets out the method for determining
system resistance curvesfor combined sprinkler and hydrant
systems.
D2 SYSTEM RESISTANCE CURVE EQUATIONS The equations to be used
for thedetermination of the system curves are as follows:
For sprinkler only operation . . . . . . . . Ks Qs(P
sP1)0.5
For hydrant only operation . . . . . . . . . Kh QhPh
0.5
whereKs = constant for the sprinkler systemQs = maximum
calculated flow rate required for the sprinkler system (in
accordance
with the requirements of AS 2118)Ps = pressure at the sprinkler
connection to the combined sprinkler/hydrant riser
to maintain Qs aboveP1 = pressure equivalent of the height of
the hydraulically disadvantaged sprinkler
array above the hydrant connection to the combined
sprinkler/hydrant riser.Kh = constant for the hydrant systemQh =
required flow rate for the specified number of hydrantsPh =
pressure at the hydrant connection to the combined
sprinkler/hydrant riser to
maintain Qh aboveSystem resistance curves can be plotted using
the following equations:
For the sprinkler system . . . . . . . . . .
For the hydrant system . . . . . . . . . . .
The resistance curve for the combined sprinkler and hydrant
systems is obtained by plottingthe sum of the sprinkler and hydrant
flows at common pressures. See Figure D1.The pressure requirements
at the pump discharge is the sum of the required combined
systempressure, P3 and P4

centre line of the highest
sprinkler in the hydraulically most disadvantaged arrayP4 =
pressure loss due to friction in the combined riser, from the pump
discharge
to the sprinkler connection calculated at the required combined
system flowrate.

APPENDIX E
WIRING SYSTEMS RATING(Normative)
E1 PROTECTION AGAINST EXPOSURE TO FIRE All wiring systems
associatedwith the operation of combined sprinkler and hydrant
systems shall have a protection againstexposure to fire rating of
not less than 120 min. This rating is represented as WS5XW.
E2 PROTECTION AGAINST MECHANICAL DAMAGE Protection against
mechanicaldamage shall be provided as listed below. The areas
indicated should not be considered asa rigid list to be adhered to
with no deviations, rather they should be considered as a guideto
the types of areas and causes of damage to be encountered. Details
of ways to achieve thegrade of protection can be found in AS
3013.WS5XAreas where physical damage is considered to be unlikely.
Examples of these
areas are
(a) masonry riser shafts with strictly limited access;(b)
non-trafficable ceiling void areas;(c) inaccessible underfloor
areas;(d) internal domestic and office situations where cabling is
mounted on walls at
heights above 1.5 m.WS51Areas where physical damage by light
impact is considered possible. Examples of
these areas are(a) internal domestic or office situations where
cable is mounted on walls at heights
below 1.5 m; and(b) trafficable ceiling void areas where access
to building services for maintenance
purposes is required.WS52Areas where physical damage by impact
from manually propelled vehicle is
possible. Examples of these areas are(a) passageways and
storerooms in domestic, office and commercial locations where
hand trucks and barrows may be used, and cables are mounted at a
height ofless than 1.5 m;
(b) plant rooms where only minor equipment is installed; and(c)
workshops where repair and maintenance, on small equipment and
furniture or
the like is carried out, and cables are mounted at a height of
less than 2.0 m.WS53Areas where physical damage by impact from
light vehicles is possible.
Examples of these areas are(a) car parks and driveways where
cars and other light vehicles are present and
cables are mounted at a height of less than 2.0 m;(b) display
areas of items such as white goods, furniture and cars where
cabling is
mounted at a height of less than 2.0 m; and(c) storage areas
where manually operated devices, such as pallet trucks, may be
operated and cables are mounted at a height of less than 2.5
m.

WS54Areas where physical impact from vehicles with rigid frames
or rigid objects, theweight of which does not exceed 2.0 t, is
possible. Examples of these areas are(a) small delivery docks where
the cabling is mounted below a height of 3.0 m(b) warehouses with
pallet storage up to 3.0 m and use of forklift trucks; and(c) heavy
vehicle workshops.
WS55Areas were physical damage from impact by laden vehicles or
objects the ladenweight of which exceeds 2.0 t. Examples of these
areas are(a) loading and delivery docks;(b) fabrication and
maintenance areas for medium to heavy engineering; and(c) large
high pile storage warehouses with forklift trucks.
Where any WS cabling traverses areas of various protection
requirement, and it is neitherviable nor practicable to change the
degree of protection at the transition points, the installedcabling
shall comply with the highest requirement of protection.
E3 PROTECTION AGAINST HOSING WITH WATER Where the wiring system
isrequired to maintain its integrity after exposure to fire and
subsequent hosing with water, itshall have the suffix W appended to
its rating, i.e. WS5XW.
