1.1 SCOPE
This Standard sets out requirements and test procedures for the routine service and maintenance necessary to ensure emergency lighting and exit sign systems are in a state of readiness for operation at all times.
1.2 APPLICATION
This Standard provides a systematic basis for minimum routine service applicable for emergency lighting and exit sign systems. It requires evidence, in the form of records and reports of completion of the periodic inspection (including survey), testing and preventive maintenance activities required by this Standard. It may also be used to develop specific routine service requirements for systems or equipment that are part of a performance solution. NOTE: This Standard may assist users meet other obligations. Recommendations on the removal, collection, movement, disposal or recycling of components or luminaires that may contain hazardous materials, for example, fluorescent lamps (mercury) and batteries (cadmium, nickel or lead), is included in Appendix G.
1.4 DEFINITIONS
For the purpose of this Standard, the definitions given in AS/NZS 2293.1 apply along with the following: 1.4.1 Adverse operating environments Any environment or condition that may adversely affect the performance or reliability of an emergency lighting or exit sign system. 1.4.2 Approved design The final design, as commissioned or subsequently modified. NOTES: 1 In Australia, this is the building solution as defined within the NCC. 2 In New Zealand, this is defined by the New Zealand Building Code. 1.4.3 Baseline data Data either provided by or derived from the approved design and commissioning thereof which, when and where provided serve as a basis for verification of results of inspection, test and survey. 1.4.4 Competent person A person who has acquired through training, qualification or experience or a combination of these, the knowledge and skill enabling that person to perform the required task correctly. 1.4.5 Defect classification and non-conformance 1.4.5.1 Critical defect A defect that renders a system inoperative. NOTE: A critical defect is likely to affect an entire system and is reasonably likely to have a significant adverse impact upon the safety of occupants of part, or all, of a building. Examples include, in a central battery system the failure of the battery or failure to sense loss of supply, a non-operational exit sign where it is the only available sign in a space, an impaired emergency luminaire, which is unable to provide sufficient light to an important aspect of a lighting system, i.e. at stairs, a change in floor level or direction.1.4.5.2 Non-critical defect A system impairment or faulty component not likely to critically affect the operation of the system. NOTE: Examples of non-critical defects include failure of one luminaire within an area served by multiple luminaires, functioning self-contained luminaires with an inoperative manual or automatic test system. 1.4.5.3 Non-conformance Missing information or incorrect feature that does not affect the system operation but is required to facilitate ongoing routine service. NOTE: Examples of non-conformance include inadequate baseline data, missing baseline data maintenance records or reports, no equipment location or identification shown or illegible labels. 1.4.6 Inspect/inspection Visual examination of the components to record settings, parameters, physical condition or fitness for purpose.1.4.7 Light source life (LSL) Length of time during which a population of light sources provides more than a minimum luminous flux percentage and less than the claim for failure fraction percentage under specified conditions. NOTE: For further information refer to IEC 63013. 1.4.8 Preventative maintenance Actions including cleaning, adjustment and replacement of components at a predetermined frequency, to minimize incidence of failure. 1.4.9 Rectify/rectification The repair or replacement of components found to be defective. 1.4.10 Responsible entity The entity responsible for the routine service of the emergency lighting or exit sign system. NOTE: Typically, the building owner, the building occupier or the building owner’s agent. 1.4.11 Routine service Inspection (including survey), test and preventative maintenance at specific intervals. 1.4.12 Shall Indicates that a statement is mandatory. 1.4.13 Should Indicates a recommendation. 1.4.14 Survey Visual inspection, typically conducted from floor level, to identify if the emergency lighting or exit sign system has been adversely altered, damaged or compromised by changes in the occupancy, environment, construction or building. 1.4.15 Test An action or procedure undertaken to confirm the correct operation or performance of a component or system.
