Yes. A DOC without EN61000-3-3 may be interpreted as incomplete. We are in the same sitiuation as you -- our products don't cause fluctuations or fllicker. Nevertheless, we write a test report for EN61000-3-3 (just a paragraph or so) citing section 6.1 -- and we list EN61000-3-3 on the DOC.
Be aware that the paranoid promulgators of the standard have seen section 6.1 to be a horrible loophole. TC77A issued 77A/303/CDV in December 1999, modified by 77A/303A/CDV in February 2000 containing the following text. Voting on these two documents closed in May 2000 and I understand they passed. An FDIS has not yet been issued. Here's the salient text from 303A/CDV : 5. Limits Replace the whole of the existing clause by the following text: The limits shall be applicable to voltage fluctuations and flicker at the supply terminals of the equipment under test, measured or calculated according to clause 4 under test conditions described in clause 6 and annex A. Tests made to prove the compliance with the limits are considered to be type tests. The following limits apply: - the value of P st shall not be greater than 1.0; - the value of P lt shall not be greater than 0.65; - the value of d(t) during a voltage change shall not exceed 3,3% for more than 500 ms; - the relative steady-state voltage change, d c , shall not exceed 3,3%; - the maximum relative voltage change d max , shall not exceed: a) 4% without additional conditions. b) 6% for equipment with : - manual switching or - automatic switching more frequently than twice per day and has a delayed restart (the delay being not less than a few tens of seconds) or manual restart after a power supply interruption. NOTE The cycling frequency will be further limited by the Pst and Plt limit. For example: a dmax of 6% producing a rectangular voltage change characteristic twice per hour will give a Plt of about 0,65. c) 7% for equipment which - is attended whilst in use (For example: hair dryers, vacuum cleaners, kitchen equipment such as mixers, garden equipment such as lawn mowers, portable tools such as electric drills.) or - is switched on automatically or is intended to be switched on manually no more than twice per day and has a delayed restart (the delay being not less than a few tens of seconds) or manual restart after a power supply interruption. In the case of equipment incorporating multiple loads, limits b) and c) shall only apply if there is delayed or manual restart after a power supply interruption; for all equipment with automatic switching which is energised immediately on restoration of supply after a power supply interruption, limits a) shall apply ; for all equipment with manual switching, limits b) or c) shall apply, depending on the rate of switching. 6 Test conditions 6.1 General - Replace « shall » by « need » in the first paragraph. - To add after the first paragraph the following paragraphs: It may be necessary to determine, by examination of the circuit diagram and specification of the equipment and by a short functional test, whether significant voltage fluctuations are likely to be produced. For voltage changes caused by manual switching, equipment is deemed to comply without further testing if the maximum r.m.s. input current (including inrush current) evaluated over each 10 ms half-period between zero-crossings does not exceed 20 A, and the supply current after inrush is within a variation band of 1.5 A. The maximum relative voltage change dmax caused by manual switching shall be measured in accordance with Annex B. John P. Wagner AVAYA Communication 11900 N.
