41.1 Commentary

1. Separate Certificates:

Issue distinct certificates for design, installation, and commissioning, confirming compliance or noting variations. Each process can be handled by different organizations, but each must issue its own certificate.

2. Competence and Liability:

The certifies must be competent and ensure the validity of the certificate, as liability may arise if the certificate is issued without due care.

3. Certificate of Acceptance:

● The purchaser is satisfied with the system.

● Documentation has been provided.

● The user is instructed on system operation and maintenance.

● The purchaser may require independent inspection or testing before completing the acceptance.

4. Independent Verification: For large or complex systems, an independent verification may be arranged by the purchaser or user, with a verification certificate issued as a result. (see Clause 42).
