CID or Control by inspection ?

A CID, or Control by detailed inspection is a visual check, carried out without disassembly, of all the components in the vehicle’s high-pressure system. Tanks, valves, pipes and fittings, shut-off and safety devices, pressure gauges, etc. operating at a working pressure of 200 bar are subject to specific monitoring and regular inspections to prevent any risk of fire or explosion.

Current regulations for NGV vehicles ?

Under the Order of 12 July 2010 and UNECE Regulation R110, the French Minister for Transport has made it compulsory for all heavy goods vehicles to undergo a CID of their CNG system every 4 years, and again in the event of an accident, when the tanks have been replaced or the system has been significantly modified, or when the vehicle has been exposed to excess pressure or involved in a fire, etc.
In France, only COFREND*-certified inspectors are authorised to carry out a CID, in compliance with a strict regulatory framework, and to issue official reports.
