Electrical appliances and power tools – safety

Electrical appliances and power tools – safety, regulations, and the latest Standards

Australian and New Zealand joint electrical Standards developed by EL-002, the ‘Joint Australian/New Zealand committee on the safety of household and similar electrical appliances, tools, small power transformers, and power supplies’, are used by manufacturers, regulators, and testing houses to ensure that appliances and power tools that come into New Zealand are constructed and tested properly, safe to use, and approved for sale.

A large number of these Australian/New Zealand (AS/NZS) Standards for electrical appliances and tools listed in Schedule 4 of the Electrical (Safety) Regulations 2010.

Ensuring safety and local input into international Standards – EL-002 committee

EL-002 is a ‘mirror’ committee of two IEC technical committees (TC); the IEC TC 61 ‘Household and other similar appliances’ committee that develops IEC Standards for appliances, and the IEC TC 116 ‘Safety of hand-held motor-operated electric tools’ committee that develops IEC Standards for power tools. Being a ‘mirror committee’ means that EL-002 can provide local input into the development of these IEC Standards and ensure that New Zealand and Australia align with these IEC Standards.

The EL-002 committee aims to reduce a number of safety risks such as electrical shock and burns to users of household appliances. The committee considers many safety factors when preparing Standards for appliances and tools. These safety factors include personal protection against electric shock, effects of excessive temperature radiation, explosion, moisture resistance, clearances, mechanical stability, hazardous moving parts, and protection against fire.

Since 2000, the Secretariat for EL-002 has resided in New Zealand. Chaired by New Zealander Derek Johns, EL-002 won the 2009 Standards New Zealand ‘Outstanding Committee of the Year Award’ – its five New Zealand members and 25 Australian members represent a wide range of industry and government stakeholders.

Publishing IEC Standards as AS/NZS Standards

EL-002 reviews IEC Standards and sets priorities to adopt these Standards as Australian/New Zealand Standards. In those cases where an appropriate IEC Standard is not available and a specific issue needs to be addressed, EL-002 develops the required Standard then recommends it to the relevant IEC committee for development as an international Standard.

‘Adopted’ IEC Standards are published as joint Australian/New Zealand Standards with or without variations as follows:

-Identical (IDT) – the AS/NZS Standard is identical to the IEC Standard and is adopted and published as an AS/NZS Standard without any variations.
-Modified (MOD) – the AS/NZS Standard is adopted with modifications to meet the local conditions and is published as an AS/NZS Standard with variations.
