Test Arrangements
–-Many items require a form of testing by law eg LOLER,
or MoD Contracts especially where lifting loads or
significant pressures are to be encountered.
–PED design and draw bespoke test arrangements,
procedures & detail drawings for the likes of adaptors,
beams, links etc. which are required to perform the tests.
– PED also have the capability to design & draw test rigs
when needed upon request.
