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

subject to periodic review and are kept up to date by the issue of amendments or new editions 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 publications will be found in the Standards Australi a Catalogue of Publi cations; this information is supplemented each month by the magazine ‘The Australian Standard’, which subscribing members receive, and which gives detail s of new publications, new editions and amendments, and of wit hdrawn Standards.

Suggestions for improvements to Australian Standards, addressed to the head office of Standards Australia, are welcomed Notification of any inaccuracy or ambiguity found in an Australian Standard should be made wit hout delay in order that the matter may be investigated and appropriate action taken.

This Standard was issued in draft form for comment as DR 95419.

Committee ME/62, Ventilation and Airconditioning, to supersede AS 1851.6— 1983

This Standard is the result of a consensus among representatives of the Joint Committee

to produce it as an Australian Standard

The objective of this document is to provide a Standardized basis for the maintenance ofthe fire and smoke control features of air-handling systems for use by system owners andmaintainers

The fire-precaution features of air-handling systems in buildings not only need to bedesigned, installed, commissioned and operated in accordance with AS 1668.1 — 1991,

The use of mechanical ventilation and air-conditioning in buildings , Part 1: Fire and smoke control , but also need to be maintained at an adequate level of performance to

minimizing property damage

In the preparation of this Standard, consideration was given to the following:

programs associated with building services

buildings, which implies that the detailed maintenance required varies from system

to system

particular features of an item of equipment and the environment in which it isinstalled

cases

Accordingly, this Standard is aimed at the management aspect of maintenance programs.Mandatory requirements for simple inspections are laid down For initiating more complexinspections and corrective actions, appropriate routines are suggested

The term ‘informative’ has been used in this Standard to define the application of theappendix to which it applies An ‘informative’ appendix is only for information andguidance

(a) Level 1 Functional checks by means of sensory inspection such as sight, touch,hearing or smell

NOTE: Diagnostic procedures are deemed to be an acceptable form of inspection

(b) Level 2 Level 1 plus cleaning, lubrication, simple routine maintenance andadjustment which does not necessitate taking the equipment out of service

(c) Level 3 Level 2 plus testing and measurement procedures with consequentialadjustments as necessary to ensure optimum effective performance These routinesmay require equipment to be taken out of service, but will generally enable rapidreinstatement if the need arises

(d) Level 4 Overhaul and test procedures which will normally necessitate an itembeing taken out of service, possibly for prolonged periods As a general rule, theseroutines are necessary only for the correction of defects found during Level 3routines and are not necessarily carried out at specified intervals

Operating and maintenance manuals shall include at least the following:

items of plant and equipment and operational features to be subjected to the maintenanceroutines described in this Standard It shall include the frequencies at which the relevantlevels of routines are to be carried out

which require inspection as a prerequisite to maintenance, and shall describe theirlocations within the building If not already incorporated in the operating and maintenancemanuals, the plant register shall include design data and unit capacities in sufficient detail

to order a replacement of equivalent performance

Each item of plant and equipment in the plant register shall be allocated an identityreference The identity reference allocated shall be unique within the building concernedand shall be indicated on the diagram(s)

NOTES:

1 Generally, an auxiliary item incorporated within the parent equipment need not be allocated

a separate identity reference

details of the performance (test results) of each item at commissioning or any subsequentrecommissioning

At subsequent inspections and tests the results shall be recorded and compared with theresults achieved at commissioning or any subsequent recommissioning Any defectsobserved and any repairs and modifications effected shall be recorded in the plant historyrecord
