In order to get my facts straight on a probable dispute with a supplier of a 'piece of equipment' they have supplied, please can my learned friends guide me on the following? The 'piece of equipment' they have arranged together and have supplied to us is: 1) an electric motor attached to 2) a pump that is controlled by 3) a throttle to control the pump using hydraulic oil from 4) a tank to an outlet and inlet valves in order to test a hydraulic system we assemble. With that should the item be CE marked and or include other documentation to satisfy the relevant regulations? I think I know the right answer, but would like another educated opinion too. Thanks,

if the individual components are CE marked then it always was that the "sum of the parts" should be considered OK - personally I would prefer the essential safety requirements consideration of the resultant machine - ie risk assessment to have considered the effect of putting the parts together for example it sounds like there there may be a pressure increase and will all the pieces take that ir will they burst?

Sorry Bruce, you are wrong, johnmann is correct. Also, there was a motor mentioned, now unless this is one huge & I mean huge motor, then it will be low voltage, thus the LVD will almost certainly apply. It does require CE marking. The directives and standards that apply will depend on the detail of the machine. The paperwork will either be a declaration of conformity or a certificate of incorporation depending on the exact detail. I have not checked & I often get the declaration & certificate bits swapped over! It's one of those receive, recieve things to me. Anyway it does need CE marking, and should meet the requirements of the MD & the LVD, thus the CEMD also. There may be others as well depending on the exact detail. It should therefore be built to the recognised standards that are written to assist in meeting these standards, e.g. BS EN 60204-1 for the electrical systems.
