132 - ANNEX C - SELECTION AND SEQUENCE OF THE TESTS OF CLAUSE 30.201 AS CONTAINED IN THE BODY OF THIS STANDARD
Specifies general safety requirements for household and similar electrical appliances. It is a base Standard which, when combined with a particular standard in the AS 3300/NZS 6300 series, becomes a complete standard for the particular appliance. It is based on IEC 335-1:1976, 2nd edition, including Amendments 1 to 6. It is identical with NZS 6300:1996 and produced as a Joint Australian/New Zealand Standard.
This Standard applies to electric heating appliances and electric motor-operated or magnetically-driven appliances for household and similar purposes.NOTES:1 Appliances not intended for normal household use but which nevertheless may be a source of danger to the public, such as appliances intended to be used by laypersons in shops, in light industry and on farms, are within the scope of this Standard. Examples of such appliances are appliances for hairdressers, soldering irons, glue pots, sterilizers, infra-red radiation appliances, feed boilers, water pumps and lawn mowers.2 Except in so far as this Standard deals with electric toys, it does not take into account the special hazards which exist in nurseries and other places where there are young children or aged or infirm persons without supervision; in such cases, additional requirements may be necessary.3 This Standard does not apply to -(a) appliances designed exclusively for industrial purposes;(b) appliances intended to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas);(c) separate motors;(d) appliances for high frequency heating except microwave ovens within the scope of AS 3301/NZS 6325;(e) radio and television receiving appliances within the scope of AS/NZS 3250; (f) appliances for medical purposes within the scope of AS/NZS 3200; (g) wires and cables; and (h) accessories.4 Gramophones and similar motor-operated appliances intended to be used in, or in combination with, electronic equipment are tested together with such equipment in accordance with AS/NZS 3250.5 For appliances intended to be used in vehicles or on board ships or aircraft, additional requirements may be necessary.6 For appliances intended to be used in tropical countries, special requirements may be necessary.7 Attention is drawn to the fact that in many countries additional requirements are specified by the national health authorities and the national authorities responsible for the protection of labour.
