We designed it to meet EN61010 as it was a piece of lab equipment. It was powered by a 5 volt, 40 amp power supply. We designed/tested for single component faults, temperature, etc. In the end, a large safety testing company informed us that no testing was required at all since it was SELV.

re: CE without LVD?
Nick, Agreed it is not yet a done deal and the UK does have one or two other Member States on its side. However, unless significantly more Member States (and certain parts of industry I may add) come over to the UK way of looking at things, then it seems highly likely that the output document from the existing Commission working group will have the lower voltage limits. Of course, there are many more procedures to be gone through before the draft that is presently being discussed between the Commission and certain other interested parties sees its way into the Official Journal as a Directive (whether that be an amendment or a replacement for 73/23/EEC - TBD still). The Parliament and various other EU bodies have to have their say and so change is certainly possible. Also, once the Directive has been published there will be a period for Member States to amend their existing national legislation to bring it into line with the new version. So 'soon' is unlikely to be less than 2 1/2 years and could easily be 5 years or even longer. Therefore, many consumer products will have been placed on the market, retired and their successors also withdrawn from the market before those companies have to start worrying about complying with the amended LVD. Of course, if you make products with a very long lifetime (then about now may be time to start planning for what may happen in the future). But don't take my word for it, speak to the DTI or the Commission yourself! Richard Hughes Safety Answers Ltd.

Re: CE without LVD?
Hi David: In regards to your suggestions below, would it not be wise to take into consideration the future plans of the LVD? The original question was specific to the LVD. My response was specific to the LVD. You raise a new question with regard to a future EU directive, the requirements of which may very well be quite onerous, and possibly quite out of line with the three-block models for injury and safety, from what I've heard. Each manufacturer should keep abreast of the EU activity, and decide for himself as to what action he should take now in anticipation of a future directive.

Hi David: It is being suggested that this product does not need safety testing and does not need to include the reference to EN 60950 and the LVD in the CE DoC, since it is SELV circuits only. The LVD applies to products with voltage ratings between 50 and 1000 V ac and between 75 and 1500 V dc. SELV does not exceed 30 V ac and 60 V dc.

These other requirements include the so-called energy hazard requirements, mechanical requirements, and fire requirements. So, the product does indeed require safety testing, but not with respect to the LVD. The DoC should indicate compliance with EN 60950. Pragmatically, since you must test for compliance to EN 60950 for these other requirements, it is just as easy to indicate compliance to the LVD via EN 60950 and thereby avoid any future argument whether the LVD applies or not.

Re: CE without LVD?
Hello David, Your issue is not new. I have been in a similar situation where the same argument was made for a product powered by SELV. However, EN 60950 addresses other safety issues with products other than electrically caused fire and electrical shock. One needs to also address the mechanical and electro-mechanical safety issues as well. A good example is an SELV powered printer.

Can you provide me with references to back my point of view? Not really. If the *product* is SELV, can you find any tests in 60950 that are applicable? I suspect not, unless it contains a battery of sufficient beef that a short-circuit could create a fire hazard. In that case, even though the LVD does not apply, the manufacturer should control his product liability under the GPSD by applying the standard as far as it is relevant. The same applies if there is a high voltage generated internally in a product supplied at SELV, FELV or PELV (or any other xLV that may have been invented). HOWEVER, if the product and the external power supply are marketed together, the that is a 'system' under the EMC Directive. While there is no such concept under the Low Voltage Directive, the DOC needs to apply to both parts of the 'system', so indeed it should declare conformity to EN 60950. There is also a need to put the CE mark on the product, for the EMC Directive. The comments about the GPSD are correct, but they don't actually indicate what the manufacturer needs to do physically in order to comply with all the rules. -- Regards, John Woodgate, OOO - Own Opinions Only. http://www.jmwa.demon.co.uk Interested in professional sound reinforcement and distribution?

Hello Group, A ITE product (not ours!) is powered by an CE marked external ac-dc power supply and has only SELV ports. I believe this product must be tested to EN 60950, and that in the CE Declaration of Conformity it must declare conformity to the LVD via EN 60590. It is being suggested that this product does not need safety testing and does not need to include the reference to EN 60950 and the LVD in the CE DoC, since it is SELV circuits only. Can you provide me with references to back my point of view? Thanks, David.

Re: CE without LVD?
Hi David: It is being suggested that this product does not need safety testing and does not need to include the reference to EN 60950 and the LVD in the CE DoC, since it is SELV circuits only. The LVD applies to products with voltage ratings between 50 and 1000 V ac and between 75 and 1500 V dc. SELV does not exceed 30 V ac and 60 V dc. Therefore, the LVD does not apply to a product that operates from a SELV source of supply. (We may be able to say that the LVD does not apply to a Class III product.) However, it is appropriate to indicate in the DoC that the LVD does not apply to the product because the product voltage is below the lower limits of the LVD. HOWEVER... EN 60950 applies to products powered from a SELV source of supply. The electric shock requirements do not apply to such products, but the other EN 60950 requirements do apply to such products. These other requirements include the so-called energy hazard requirements, mechanical requirements, and fire requirements. So, the product does indeed require safety testing, but not with respect to the LVD. The DoC should indicate compliance with EN 60950. Pragmatically, since you must test for compliance to EN 60950 for these other requirements, it is just as easy to indicate compliance to the LVD via EN 60950 and thereby avoid any future argument whether the LVD applies or not. Most of our inkjet printer products are powered by an external SELV source of supply. We test to EN 60950 and declare compliance with the LVD.
