Dear list members,
I am working from home and so I don't have access to all my
documentation.
Is there a manufacturing standard, applicable in the UK, requiring that
the laser footswitch be shrouded?
I am sure that it is in the MDA Guidance because John Parsons and I
wrote it, but that is essentially guidance for users.
I don't think it is in 60824-1.
Is it in 60601-2-22?
Regards
Harry Moseley
