FCC part 15 section 109
Hello group, Part 15, section 109, states that as an alternative to the radiated emission limits shown in paragraphs (a) and (b) of this section, digital devices may be shown to comply with CISPR22 3rd ed. Further-on is stated that the testmethods of part 15 (referring to ANSI C63.4) apply. Question: If a lab performs Part 15 measurements for Class B devices below 1000MHz according to CISPR22:1997 with - the limits of CISPR22 - the procedures of CISPR22 - at a 10 meter distance as per CISPR22, Are these measurements performed in an correct way? Regards, Kris Carpentier
Australian compliance to ARE: creepage v breakdown voltage
Hello, According to the latest version of the Telecommunication Labelling Notice 2001, products in the Category A50 are deemed to comply with ACA TS-001-1997 and AS/ACIF S043-2001. No problem for TS-001, but S043 needs Compliance level 3 only since January 1rst 2002. The general approach is that testing for S043 must be done by a Recognised Testing Authority. After verifying the latest list of RTA´s http://www.nata.asn.au/downloads/rtalist.pdf of March 7th, only 1 lab seems to be listed as RTA and it is not even located in Australia, but in the US. From my reading of the Labelling Notice, Schedule 3 seems to give however other possibilities to comply, like a Certification or Competent body. Any-one can shed some light on this issue? Regards, Kris Carpentier
Re: New Generic ENs
Richard, EN 61000-6-1 has common deviations in clause 2, 3.5, Table 1 and Table 5. EN 61000-6-3 has common deviations in clause 2, 4, 9, Table 1 and Annex A. Both standards have an Annex ZA showing comparison between international and EN/HD standards. Hope this helps.

noise immunity on mains powered equipment
Hello, Has any-one ever heard about a standard (non-military) that describes noise immunity of mains powered equipment. Testing seems to be done by the current bulk injection method. the standard is not IEC 61000-4-6.

Re: TNV-2 to Earth requirement
Ed, I do not know your specific application. Therefore - if your TNV-2 circuit is connected to a telecom network - EN60950, 2nd ed/A4 andNorway/Sweden requires SI for the mains. (see EN60950:1992/A4:1997, AnnexZB) SI means clearance, creepage, DTI and dielectric strength for 230V mains. Why don's you use EN60950, 3rd edition? SubClause 6.2.1.2 asks for an insulation between earth and a telecom network, tested only with 1.5kV insulation test. As I read the standard, additional requirements exist - for Norway Sweden - but only for DTI (ref. EN60950:2000, Annex ZB). Regards, Kris Carpentier All, I have a DC to DC filter which is rated 32 - 72 VDC input and output which I am considering to be TNV-2 according to EN60950/IEC60950 2nd edition. This filter has a metal chassis which is earthed, and it will be installed in a service access area only by qualified service personnel. It is not permanently connected or pluggable type B, and does not have a provision for a permanently connected earthing conductor. With all this considered, it seems that Norway and Sweden are the only Countries that require Supplemental insulation for a primary circuit between this TNV-2 circuit and earth. Is there any way around this requirement due to this filter operating at 72VDC and not being directly connected to mains? Any help would be appreciated.

Standards applicable to crane equipment
Dear all, The product concerned is a metal box located on the (metal) roller bridge of a crane and controls the movement of that bridge. It is powered by min. 48Vac and receives commands from an operator with a battery powered hand-held radio transmitter command box. The 48V ac power supply is connected to the metal frame of the roller bridge. The crane nor roller bridge are connected to ground by means of a fixed connection. All additional metal parts are connected to the fixed or moving part of the crane. Questions: 1.- What standards and regulations are applicable to both products for EMC, Safety and Radio, for US and EU market? 2.- Can the metal frame be considered as reliably connected to PE?

high temperature circuitbreaker
Hello group, Circuit breakers and residual current operated circuitbreakers for house-hold applications are typically cetified at 40 degree Celcius. If these types are built into other products, they do not comply with their temperature rating as specified in the safety certificate. Does any-one know about references to circuit-breakers(230V ac, 10A) that can work safely at higher temperatures (70...90 degrees) Regards, Kris Carpentier --- This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.

Question on FCC part 15
Hello group, A data acquisition board for building into a PC has been tested to the European standard EN 55022, class B by an accredited testlab in Europe. This configuration is not meant for a residential market and I suppose FCC part 15 is applicable. Which procedure should be followed for part 15, DoC or verification? Compliance required to Class A or Class B? If the board can be built in different kind of PC's, how is testing performed? To determine the max. frequency to test for, do I need the max. internal PC frequency or the max. internal freq. of the board? Will the EN 55022 results be accepted by an FCC lab?, can a European CAB do the testing? Any help is appreciated.
