CENELEC web site?
I recall months ago the anouncement of a CENELEC web site. Access was very limited at that time. I would be interested in checking the site again, but I have forgotten the address. Could someone please advise me of CENELEC's web site address. Also any comments on its contents and user friendliness would be appreciated. Thanks, R.

New CISPR22 requirement
The most recent issue of CISPR22 (Third edition, Nov. 1997) requires conducted emissions testing on signal cables (section 5.1). Section 9.5 provides the procedures for making such measurements. Alternative methods are suggested involving Impedance Stabilization Networks and Current Probes. All types of cables are covered (e.g. balanced/unbalanced, screened/unscreened, single pair/multiconductor, etc.). Has a CENELEC version of CISPR22-1997 been released or drafted? If not released yet, when is it expected? When would it be expected to be communicated by the Commission, and when would it become mandatory? Does it contain a requirement for conducted emissions on signal lines? Does anyone have any particular concerns regarding compliance with this standard? Thanks in advance. R.

EN41003 not applicable to ITE?
Could someone confirm that the latest version of EN41003 states that it is not applicable to ITE? I think I recall someone previously saying that this exclusion was added to the 1997 version. If this is correct, I would appreciate it if someone could fax me the page with this reference. Thanks in advance. R.

VCCI ?
Questions regarding VCCI? 1) Is VCCI for a product ever MANDATORY for it to be imported into Japan? 2) If VCCI is not mandatory, is it mandatory to meet certain emissions limits for importation into Japan? 3) If VCCI is not mandatory, for what type of products is VCCI most desirable (that is, what products won't sell without VCCI?) 3) What are the costs associated with membership, and with specific product approval?

re: German Regulations
I have obtained German BAPT standards, as well as those from other European countries, from BSI. Contact their foreign sales office at: 44-181-996-7525, 7047-fax. For BSI, ETSI, CENELEC, etc. standards contact their main customer service number at: 44-181-996-7000, 7001-fax R. Grant Pinto Alcatel Data Networks 703-724-2759 703-724-2132-fax grant.pi...@adn.alcatel.com I have been informed that Germany has adopted I-ETS 300330 with exceptions. Does anyone know where I can find an English version of 1) the German document Vfg 5/1996? 2) the formally issued German document BAPT 222 ZV 122, March 1997? ( I have a draft copy, Sept 96 version). Alternatively, can anyone point out the differences, if any, between the Sept draft and the released document? Thank you in advance for your assistance. Don Umbdenstock
What is RC10000 ?
Does anyone know of a standard numbered RC1 which may relate to environmental, quality, and/or manufacturing issues? It may be of European origin. Thanks in advance. R. Grant Pinto grant.pi...@adn.alcatel.com 703-724-2759 703-724-2132-fax
LVD and 48VDC equipment
I would appreciate your comments on the following thoughts/philosophy: The scope of the Low Voltage Directive excludes equipment with a voltage rating (means powered from) -48VDC (or -48 to -60VDC) sources (including ITE/Telecom equipment.) [Definition from EN60950 - Rated Voltage: The primary power voltage as declared by the manufacturer.] If the equipment is ITE, it is included in the scope of EN60950. EN60950 has no lower voltage limit and specifically includes equipment intended to be connected to a telecommunications network. If the equipment is ITE and not Telecom, the equipment could be tested to EN60950 as this is a relevant standard. Of course the equipment must be CE marked persuant to the EMC directive. The Declaration of Conformity (DOC) should refer to the EMC directive, but not the Low Voltage Directive. If the equipment is ITE/Telecom hybrid, the TTE directive requires (Article 4) that the equipment satisfy requirements for user safety and safety of employees of public telecom networks operators. It also requires that the equipment satisfy requirements for the protection of the public telecom network from harm. Whether the LVD applies or not, safety is required. Therefore equipment should be tested to EN60950 as this is the relevant standard. CE marking would be required for the TTE and EMC directives, but not the LVD as the DOC would show. In conclusion, 48VDC ITE/telecom equipment should be tested to EN60950, but CE marking, and the associated DOC, should not include reference to the LVD. Thanks, R.

Source for 120 ohm E1 cable?
I am looking for a manufacturer of cable suitable for carrying the European 120 ohm E1 (CEPT1) signal (2 or 3 twisted pairs). It should be UL/CSA listed/recognized/certified or listable/recognizable/certifiable (that is, meets the FT4 flame tests), be double shielded (braid/foil) and should be dimensionally suitable for the RJ48 8 position modular connector. It would be similar to CAT5 cable except 120 ohms. I am not looking for a custom solution, but an existing product - probably manufactured by a European company (none of the big US cable manufactures have it). Any suggestions would be appreciated.

EN61000-3-2 applicability ?
Now that EN61000-3-2 is applicable under the EMC directive, I have the following thoughts and questions: 1) The scope of this standard indicates it is applicable to equipment having an input current up to and including 16 A per phase. The first paragraph in section 7 states that the limits for high-power equipment (1kW) for professional use are kept under consideration. A single phase equipment operating at 230V and 16 A may draw as much as 3680W. a) Does kept under consideration mean no limits are provided? b) What limits apply to such equipment rated at 1000-3680W? c) To what profession is this standard referring? (Section 3.15 defines professional equipment as that equipment for use in trades, professions, or industries and which is not intended for sale to the general public. Wouldn't many types of equipment fall within this (vague) definition? 2) Section 7.4 and Annex C.10 (for Class D ITE) both state that equipment shall be tested at rated load condition. a) If Class D ITE equipment is rated higher than 16 A, is this standard applicable to such equipment? b) If the Class D ITE equipment rated higher than 16 A can be legitimately configured such that it operates at less than 16 A, does this standard apply to such equipment? If so, would it only need to comply at currents up to 16 A? At what current should the equipment be tested? c) If EN61000-3-2 does not apply to such equipment, what standard does? My own opinions are that I would ignore the first paragraph in section 7 with respect to the reservations on limits for high power equipment (because otherwise it would be to easy to simply declare a product as professional equipment; and I would interpret the 16 A limitation of the scope to mean that this standard is NOT applicable to equipment that is rated higher than 16 A even if it can be configured to operate at less than 16 A. Please let me know your opinions. Thanks, R. Grant Pinto rgpi...@telenet.com 703-689-6270
