STANDARDS AUSTRALIA/STANDARDS NEW ZEALANDAustralian/New Zealand StandardIn-service safety inspection and testingof electrical equipmentSECTION 1 – SCOPE AND GENERAL1.1 SCOPEThis Standard specifies procedures for the safety inspection and testing of low voltage single phase andpolyphase electrical equipment, connected to the electrical supply by a flexible cord and/or connectingdevice, which is new equipment placed into service for the first time, is already in-service, has beenserviced or repaired, is returning to service from a second-hand sale, or is available for hire.This Standard also includes fixed RCDs and portable inverters that generate or produce low voltage.NOTE — Additional requirements for portable generators are covered by AS/NZS 3012.Typical examples of equipment covered by this Standard are:(a)(b)(c)(d)(e)(f)(g)Portable, hand-held and stationary appliances, designed for connection to the low voltage supplyby a flexible cord and plug;Cord sets, cord extension sets and outlet devices (also known as electrical portable outlet devices,EPODs or power boards);Flexible cords connected to fixed equipment in hostile environments;Portable safety isolation transformers (includes power adaptor/plug-pack, both of the transformerand switch-mode type);RCDs – portable type (PRCD), socket outlet type, and fixed switchboard type;Battery chargers including commercial and industrial;Portable and transportable heavy duty tools such as high pressure washers and concrete grinders.1.1.1This Standard does not apply to electrical equipment (such as suspended light fittings), at a height of2.5 m or greater above the ground, floor or platform, where there is not a reasonable chance of a persontouching the equipment and, at the same time, coming into contact with earth or any conducting mediumwhich may be in electrical contact with earth or through which a circuit may be completed to earth.1.1.2This Standard does not apply to equipment which would need to be dismantled to perform the inspectionand tests specified in this Standard.1.1.3NOTE — If, for some reason outside the scope of this Standard, equipment has to be dismantledto verify safety, this action is only to be performed by a technically qualified person.Functional checks are not included in this Standard.1.1.4This Standard applies only to equipment in-service at a place of work or public place, or offered for hire.1.1.5This Standard does not apply to fixed or stationary equipment connected to wiring that forms part of the5 of 46
electrical installation and falls within the scope of AS/NZS 3000.1.1.6This Standard does not apply to equipment whose nature is that of a medical device as defined inAS/NZS 3551.1.1.7This Standard does not apply to demonstration stock in retail or wholesale outlets.1.2 GENERALEquipment needs to be subjected to regular inspection and testing to detect obvious damage, wear orother conditions which might render it unsafe. Equipment shall not be dismantled to perform inspectionand testing, nor tested to destruction.NOTE — Unless otherwise specified, all a.c. voltage and current values referenced are expressed in rootmean square (r.m.s) values.1.2.1 New equipment1.2.1.1In Australia, when the equipment is new, the supplier is deemed responsible for its initial electrical safety.New equipment need not be tested but shall be examined for obvious damage. Where deemed compliantthe owner or Responsible person shall ensure it is tagged in accordance with 2.4.2.1.1.2.1.2NOTE — This clause is drawn to the attention of owners of computer and office equipment, who mayarrange for the tagging action to be undertaken by their in-house Competent person.In New Zealand, the equipment shall be inspected, tested and tagged on entry to service.1.2.2 In-service equipmentEquipment already in-service shall be inspected and tested in accordance with Section 2.1.2.3 Fixed or stationary equipmentFixed or stationary equipment connected by fixed cable or flexible cord:(a)(b)Which is not flexed in normal use or exposed to damage nor is in a hostile environment, does notnormally constitute a hazard sufficient to warrant routine in-service electrical safety testing.Accordingly, the testing of such equipment is not required by this Standard;Where the flexible cable or cord is flexed on equipment which is moved for restocking,maintenance, cleaning, for example, shall require in-service testing.1.2.4 Hire equipment1.2.4.1 Responsibility for hire equipment at the commencement of hire(a) New equipment from the supplier shall enter service in the hire industry in accordance with 1.2.1;(b)(c)The hirer has the responsibility to ensure that hired equipment complies with the requirements ofthis Standard at the commencement of hire;Hirers may combine the function of the tag specified in 2.4.2 and their in-house 'Ready for hire'tag,by colour-coding it to comply with 2.4.2.1.2.4.2 Responsibility for hire equipment during hireResponsibility for testing, inspection and tagging passes to the hiree. The appropriate time interval toretest shall be derived from Table 4, by assessing the environment in which the equipment is utilized.6 of 46
