2012 CTL Plenary Meeting Question
Is it acceptable to issue CB Test Certificate for miniature fuse-links with dimensions deviating from the Standard Sheets of IEC 60127?
Examples:
1. The sub-miniature fuse-link of Standard Sheet No. 4 of IEC 60127-3, with shape and dimensions as specified in Standard Sheet No. 2;
2. The length and/or diameter of cartridge fuse-link is longer or less than those specified in the Standard Sheets of IEC 60127-2;
3. The sub-miniature fuse-link of Standard Sheet No. 3 of IEC 60127-3, with shape and dimensions as suggested by the manufacturer.
Decision
It is not allowed to issue a CB Test Certificate for miniature fuse-links with shape and dimensions that do not comply with the dimensions specified in the standard, even though all other requirements are met.
Rationale:
It is not appropriate to accept non-standardized specifications to issue a CB Test Certificate, which is to confirm compliance with internationally validated IEC standards.
