Sorry overlooked that a bit and the problem seems gets worse as time goes on.

RE: [PSES] LVD and US Safety Workplace Requirements for products.

Painful is a relative word. We’ve seen the most painful part is the critical components. You don’t need UL R/C to get approvals outside the USA. Either change the components to be UL or plan on testing them all. From: McInturff, Gary [mailto:gary.mcintu...@esterline.com] Sent: Tuesday, June

RE: LVD and US Safety Workplace Requirements for products.

Hello Ian, There are national differences in the USA for IEC/EN 61010-1. Therefore, you need to get a copy of ANSI/UL 61010-1 and work with an established NRTL. Best regards, Ron From: emc-p...@ieee.org [mailto:emc-p...@ieee.org] On Behalf Of Ian White (UK) Sent: Tuesday, June 28

Gary If they are only spare parts for specific equipment equipment which is itself properly CE marked, and they don't affect the CE status of the complete equipment, then they do not need to be CE marked. If you still feel you need to make some statement about their status then you are free to iss

You can't issue a Declaration of Incorporation for something which is not within the scope of the Machinery Directive. Just because something is a component of a machine does not necessarily make it 'machinery' so far as the Machinery Directive is concerned. For most machinery electrical equipment
