Abstract

Specifies performance requirements for ballasts for tubular fluorescent lamps for use in a.c. supplies up to 1000 V. This applies to complete ballasts and their allied components such as reactors, transformers and capacitors. This document should be read in conjunction with general and safety requirements of ballasts covered in AS/NZS 60920.

Scope

This standard specifies performance requirements for ballasts excluding resistance types for use on a.c. supplies up to 1000 v at 50 Hz or 60 Hz, associated with tubular fluorescent lamps with pre-heated cathodes operated with or without a starter or starting device and having rated wattages, dimensions and characteristics as specified in IEC Publications 60081 and 60901. It applies to complete ballasts and their component parts such as resistors, transformer and capacitors.
This standard should be read in conjunction with IEC Publication 60920 IEC 61347-2-8. This Standard excludes A.C. supplied electronic ballasts for tubular fluorescent lamps for high frequency operation specified in IEC Publication 60928 AS/NZS 60928.
