Re: EMC and Class 2 equipment
Hi John: Ground connections is usually nice to have when dealing with EMC. But what about EMC and a class 2 (double insulation) power supply (shall comply with MIL-STD-461E) . I'm thinking on, what to do with the regularly Y-caps, does it really have any meaning with these caps when ground is absent? No, it has no meaning. A Y-cap is earthed/grounded at one end. If there is no earth/ground, there is no Y-cap, by definition. No. According to IEC 384 (1981) Capacitor of Class Y A capacitor of a type suitable for use in situations where failure of the capacitor could lead to danger of electric shock. A Y-cap can be used between primary and secondary of a Class II product and it is still designated a Y-cap. Such construction is not uncommon for EMC suppression in Class II products. Y-caps of relatively small values are also used across the isolation barrier of a modem, e.g., from TNV circuits to SELV circuits. In such applications, the Y-cap is not connected to the primary circuit and is not connected to ground. It is a signal-carrying component used in a situation where failure of the capacitor could lead to danger of electric shock (from the telephone line).

RE: EN55022:1998
Not yet. CISPR/I is working the issue and has 3 CD's in circulation at the moment. Nothing yet, however, on non-invasive measurements using current probes and capacitive voltage clamps -- measurment method C.1.3 and C.1.4. Its on the agenda for WG3 and hopefully a CD will be forthcoming by the September meeting. Considering we have not reached the voting stage in any of these documents, it is virtually impossible to have completed amending CISPR 22 by August of 2003. We may be close, however. John P.

RE: EN55022:1998
Richard, We (I'm on CISPR SC I WG3) are still working on fixes to CISPR 22:1997 in this area. I would not expect to have the necessary amendment published by August of next year. Stranger things have happened, but I would be highly surprised. What happens with EN 55022:1998 in the meantime is up to CENELEC. Work is being done on the specifications for the ISNs that will require existing units to be re-worked by the manufacturers.

polonium sources
The issue of sending polonium static elimination devices to our customers has come up. It is my understanding that the devices in question, which are 10CFR31.3 devices (500 microcuries), can be sent, and we need to notify the federal Director of Nuclear Material Safety and Safeguards. In addition, the customer must comply with the requirements of 10CFR31.5, which deals with testing, record keeping, transfer, safety documentation, tracking, reporting theft or loss of material, among other things.

RE: Considering a rooftop OATS
Doug, Rooftop sites have a number of problems. I'm sure the folks who have actually built them can elaborate more, but one that jumps to mind is the fact that you will have a worse ambient than at ground level. The VHF and UHF signals that comprise the ambient tend to be line of sight, and raising yourself above the average terrain increases the distance at which transmitters may be received. Thus, you'll suffer interference from FM and television stations that are farther away than if you were at ground level.

RE: DSSS WLAN for Australia
Desmond, Not as simple as your questions to explain I am afraid. Below is a very brief outline and by no means should be looked upon as detailing all the issues. Hope it helps. A 2.4GHz spread spectrum device must comply with: a) ACA Radiocommunications Class Licence (Spread Spectrum Devices) requirements with respect to transmitter operation/use. The Class Licence specifies transmitter characteristics (freq of operation and eirp limits etc); and b) ACA Radiocommunications (Electromagnetic Radiation - Human Exposure) Standard 2001 (otherwise known s the HES or Human Exposure Standard) requirements with respect to radiation characteristics (SAR etc). No DoC is required regarding the Class Licence however a DoC and associated Compliance Folder etc is required with respect to the EMR regulations. NOTE: The host equipment would naturally need to comply with Australian safety, EMC and telecommunications regulations if applicable. So, very brief answers to your questions concerning EMR requirements for the spread spectrum device: 1. Australian importer or their Agent need to establish a product Compliance Folder and sign a DoC; 2. C-tick mark required in terms of EMR; 3. If overseas manufacturer/supplier of product does not have a local office in Australia or where that local office is not the direct importer of their product then the easiest solution is for:- a) overseas manufacturer/supplier (company A) to enter into agreement with Australian organisation (company B) offering Agent services to Australian importers (companies C); and b) for any Australian importer of overseas manufacturer's/supplier's product to sign an Agent agreement with company B. 4. The advantage of the arrangement outlined in 3 above is that company B (offering Agent services) already has applied to use the C-Tick mark and has been issued with a unique ACA Supplier Code to be used in association with the C-Tick mark so the product need only one compliance label for all Australian importers (otherwise, if each Australian importer assumes compliance responsibility for the product they import the overseas supplier is faced with having to label product for each importer separately - i.e. different ACA Supplier Code for each importer); 5. No fees in terms of approval submission fees if that is what you mean; 6. No approval submittals required so no lead times there. Under the approach outlined in 3 above, the lead times are dependent upon how quickly:- a) the overseas manufacturer can provide company B with the necessary product information required for the Compliance Folder and satisfy them that their product complies with all requirements; and b) Agent agreements are signed between at least one Australian importer of the product (a company C described in point 3 above) and the Agent (company B).

Re: CNS Standards
Hello All, Just one clarification regarding update of South Korea's APEC TEL MRA Annex I - this recent update does now allow for Canadian labs to be accredited with full scope of the Korean requirements. This bilateral agreement has been in place between Canada and Korea for several years, by virtue of the Korean/Canadian MRA signed in the early 90's. However, the initial agreement allowed for only one lab in either country to enter into a confidence building period. The newly updated Annex and procedures now allows for any accredited Canadian lab to add the Korean requirements to their scope, including immunity (which had been caught in the rollover from confidence building to full rollout in accordance with APEC TEL). In keeping with the APEC TEL MRA procedures, Korea has updated Annex I and their full list of technical regulations (relating to Telecom, EMC and Wireless approvals). However, this does not automatically translate into open acceptance of reports from any country. These agreements (such as the one that exists between Canada and Korea) must be in place, before Phase I can be fully implemented.

The APEC TEL MRA was sign by the DGT in Taiwan, thus allowing foreign testing lab to the EMC on telecom equipment only. The extension, in USA, of this MRA to Information Technology Equipment was negotiated separately by the FCC (actually by the means of an exchange of letters between trade office in Washington and Taipei for political reasons). The terms used in those letters states that Designated US based lab data would be recognized by BSMI for tests performed on US products. In fact, Us tests labs can only test US products. This situation made me test in Taiwan for the last two years, waiting for the Taiwan Foreign affairs to sign the same type of agreement with Canada. On the other hand, South-Korea was just (see attachment) update their Annex 1 of the APEC Tel MRA, including all EMI and EMS test. So, accredited tests labs, even American ones, if they have their scope modified to include the South-Korean requirements, could be designated. I just received mine a few days ago.

I'm sure it has the usual disclaimers on it warning that in the event of a conflict between the original and the translation, the original Chinese prevails, though. Thanks for your post detailing the MRAs. I think it helps make some sense out of it for those who aren't following it regularly. About the in-country testing required note on our web site, that's actually intended to refer to telecom testing. BSMI has recognized EMC test reports from designated labs even before the APEC TEL MRA, and DGT adopted this practice when they began evaluating EMC compliance on telecom equipment two years ago. On the telecom front, Taiwan has been ready for some time to move forward with the US on Phase I and more recently Phase II of the MRA. It's just a matter of designating labs outside of Taiwan. As far as I know, the only lab designated for any standard besides EMC is CCS. For wire line telecom, until there are labs designated outside of Taiwan to test to the standard that applies to a product, the practical advice is that it's got to be tested (for telecom) in-country. Sorry to cause confusion. -Fred Borda Compliance International www.typeapproval.com At PM 12:50 04/22/02 -0700, Barbara Judge wrote: Hi Fred, Is that an official translation of CNS 13438? By the way in visiting your website I notice that you stipulate that In-country testing is required for most equipment Under the APEC Mutual Recognition Arrangement, both Taiwan and the US being signatories, it is not required that testing be conducted in Taiwan. Testing may be conducted by a Conformity Assessment Body (CAB), in the U.S., that has been
