Pierre, UL783 (Battery Operated Flashlights and Lanterns) is not the standard for intinsic safety. It is the standard used if your head lamp is used in non-hazradous environments. For intrinsic safety, you must use UL913 (standard for intrinsicaly safe equipment).

Reading your messages, I understand that no EMC or safety standards applied to the basic products. Only the product with switch mode power supply could be tested against EMC standard, if any applied. I understand Gary will check this point. Furthermore, when intrinsic safety is wanted, I have to comply with UL 783 safety standard. Am I right ? I thank you a lot for your cooperation, Best regards, Pierre Selva >Messsage du 21/11/2002 20:22 >De : Gary McInturff <[email protected]> >A : Peter Merguerian <[email protected]>, Pierre SELVA <[email protected]>, <[email protected]> >Copie à : >Objet : RE: EMC and safety for Head Lamp > > > Seems like they can have a switch mode supply of some sorts. I would look under digital devices in the FCC regs to see if they are exempted.
