On successful completion of the pattern approval process you will be issued with a certificate of approval  (also known as a pattern approval certificate) which is valid for five years and contains an approval number. Certificates of approval are usually comprised of three sections:

• a certificate which consists of the advice and conditions of approval
• a technical schedule which describes the pattern and any variants
• a test procedure which specifies the tests (which are not covered by other published test procedures) for verification and the maximum permissible errors

To find a particular certificate:

• use the Search facility (top right)
• enter the certificate of approval number (use a solidus to separate the numbers, e.g. 12/1/20) in the Publication Search (in the top navigation bar)
• select the correct approval category (below) and sub-category (where certificates are listed in numerical order)
