3. Cooling towers that do not work with surface water

Cooling towers that have been in service for a whole year: sample 1 between 1 April and 31 May. sample 2 between 15 July and 15 September. Cooling tower that has been in service for a limited period: sample 1: at least two weeks after initial operation. sample 2: in the middle of the operating period.

FAQ

Frequently asked questions

A witness audit is an independent evaluation to assess whether a certification or inspection body correctly applies the relevant standard during audits or inspections.

It clarifies differences in how standards are interpreted, identifies bottlenecks in the audit process, and highlights areas for improvement.

The findings help standard owners and bodies to improve auditor training, strengthen the audit system, and — if needed — create and follow up on an improvement plan.
