This document is to achieve consistency in the drafting of symbols and drawing sets to be used for electrical layouts, including drawings for isolation, earthing and bonding and High Voltage.

While this standard was developed for AS 7650 compliance, the process can be used for compliance with any standards.

The onset of computer aided design (CAD), the increase in application of geospatial and building information modelling (BIM) and requirement for data interoperability has increased the need for consistent standard and efficient ways of drawing and representation of symbols across industry in every discipline to ensure quality drawings that meet current and future industry needs.

This Standard aims to provide guidelines towards the definition of a common format to express content, applicability and purpose of site-specific layout drawings and equipment level symbols for: isolation, earthing and bonding, and High Voltage.
