Craig, here is my opinion. Your equipment does fall into the scope of the two standards. The exemptions are not listed in the scope. Compliance is mandatory for devices listed in the scope, but some devices are exempt from testing as noted elsewhere in the standards. Therefore, if your equipment is covered by the scope, you must list the standards on your DOC even if you are exempted from testing.
Richard Woods ---------- From: Craig Hensley [SMTP:[email protected]] Sent: Wednesday, January 03, 2001 12:50 PM To: [email protected] Cc: Craig Hensley Subject: EN61000-3-2 / EN61000-3-3 (Again) This is probably a gross over-simplification, but I want to make sure I understand the applicability of the new EN61000-3-2 (harmonic) and EN61000-3-3 (flicker) standards. In reviewing the standards as well as previous communications within this group I have arrived at the following conclusions. EN61000-3-2 - Applies only to products with input power higher than 75W. Per paragraph 7.4 of the standard, "no limits apply for equipment with an active input power up to and including 75W". EN61000-3-3 - Per paragraph 6.1 of the standard, "Tests shall not be made on equipment which is unlikely to produce significant voltage fluctuations or flicker". Per an earlier e-mail from Gert Gremmen "unlikely" means that the equipment has no variations in power supply current, or variations that cause voltage fluctuations below the most stringent level in the standard. In general: - Equipment with a power consumption below 100 VA max is unlikely to create flicker problems, and, - Most equipment under 500VA will not create flicker problems. You could actually do a simple check the 230V mains side to see if the product causes dips or fluctuations. If there are no dips there is no need to measure. If a product does not fall under the applicability of EN61000-3-2 or EN61000-3-3 per the above explanations, what is the consensus regarding referencing these standards on the DoC? Based on some earlier e-mails, it appears that a few of you are going to add these to the DoC. This should take away questions that may arise with DoC's that do not contain these standards. Based on this approach, couldn't you also reference other non-applicable harmonized standards? Recently I have been asked to sign a document from one of our distributors that states all product provided after 01/01/01 will comply with EN61000-3-2 and EN61000-3-3. However, my products fall outside the scope of these standards (per above explanations), so what I am wondering is can I say I comply because I have evaluated the standards and found they are not applicable. I face the same dilemma on the DoC's. Is it reasonable to claim compliance via non-applicability? I apologize for the conversational tone of this e-mail, but I am interested in any other views and opinions. Best Regards for 2001, Craig Hensley Iomega Corp.
