出版:Standards Australia

专家解读视频
This standard applies to machines having rated outputs larger than those included in BS 170 and smaller than those in BS 169 and having windings insulated with Class A material as defined in Appendix A, wound for voltages not exceeding 7,000 Volts. This standard does not apply to turbo-type machines, rotary convertors, motors for traction purposes, or to machines with flame-proof enclosure. This standard may also be applied to machines of larger ratings, by special arrangement between the manufacturer and purchaser. Continuously rated machines to this specification (other than totally-enclosed machines) have a sustained overload capacity as distinct from machines having a continuous maximum rating.
