Beam testing
Manufacturers are required to draw up technical files for the machinery they make. These must include:
■ drawings of the machinery and its control circuits;
■ the specifications and standards used in the design; and
■ information about relevant test results and other data.

Technical reports and certificates from other organisations may also be included as well as the Declaration of Conformity or Declaration of Incorporation (for the individual items of machinery that make up an assembly).
Technical files demonstrate how machinery meets relevant essential health and safety requirements and, as such, are useful for both manufacturers and national enforcing authorities. We can supply a proof load test report for your technical file.
