Which LVD harmonised standard[s]?

Udtwmc
Hi all,


I'm new to designing electrical equipment for 'test rigs', equipment I wouldn't define as machinery. On these rigs there may be measurement instrumentation, a low voltage control panel with a PLC, switchgear and control gear along with emergency stop circuits, The plant may have pipelines containing non-hazordous liquids/gases and control valves and pumps, but no external moving parts. 


So i'd like to know if there is a definitive LVD harmonised standard that I can buy with the aim of CE marking this equipment (obviously there's the EMC directive to condider but i'm just thinking in terms of the LVD as I don't beleive the Machinery Directive is relevant here, but maybe i'm wrong). Can for example EN60947-5-1 cover the LVD or is there a host of other standards I've not considered?


Also, where can the IET wiring regs BS7671 be of use for the purpose of CE marking electrical equipment?


Thanks in advance

    The LVD does effectively “trump” the LVD, not because it is more important, but because it has inbuilt the requirements of the LVD.

    They are mutually exclusive effectively.


    If you look at the definition of machinery, coming from the machinery directive, or HSE it does not require the moving part to be accessible to be covered under the machinery directive, it is more to do with the hazards that are posed and the definitions.


    I doubt also that you will find a c-type for a test rig!


    Try here for links to the directives and listings of harmonised standards for all the directives.

    Don’t forget 13850 for e-stops too! ;)
