Listed below are some commonly used electrical standards and approved codes of practice. Additional standards and codes of practice would generally be needed to satisfy a specific application – it is the responsibility of the specifier to select and apply these. You should ensure that the standard you use is the current one.
The standards are organised into a number of topic areas and are ordered with the lowest number at the top of each table:
- Electrical and Power
- Electrical Appliances
- Electromagnetic Compatibility
- Flammable Atmospheres
- Machinery
