Publication

Editorial policy

The standards used to research, write and update this publication.

Evidence first

Primary public sources, legislation, peer-reviewed research and recognised technical bodies are preferred. Manufacturer material is used only for claims about that manufacturer or a defined technology.

No invented authority

The publication does not claim projects, engineering experience, partners or qualifications it does not have. Technical judgements that require plant data are identified as site-specific.

Review and correction

Time-sensitive pages show review dates. Material corrections are made promptly and the source and corrections policy explains how to report an issue.
