If the manufacturer’s production control system is deemed suitable documented system, 1399-1 evidence, performed initial type tests and tests necessary for production monitoring the IMK issues an FPC certificate in accordance with the Construction Products Regulation CPR.
New version of BS EN – Andrews Fasteners Ltd
Once certified the manufacturer wn issue a Declaration of performance DoPand to affix the CE mark on its products. An integral part of the manufacturer’s production control system is the implementation of initial type tests and tests for the monitoring of production.
Bolting material tests can be performed at IMK in an accredited laboratory.
Initial type tests include: Comprehensive testing of bolting assemblies elements 13499-1, nuts, washers according to the following standards: Certification of manufacturers of bolting assemblies. Non-preloaded structural bolting assemblies – Part 1: General requirements, EN High strength structural bolting assemblies for preloading – Part 1: Testing of the screw material An 1439-1 part of the manufacturer’s production control system is the implementation of initial type tests and tests for the monitoring of production.
