RE: World-wide approvals radio transmitters
I thought Japan - VCCI was for ITE equipment only? or am I wrong? I believe that Japanese safety standards are JIS - #.

RE: Certificate of Incoorporation???
Andy, I have never heard of the term certificate of incorporation. However, Article 4(2) and Annex IIB of the Machinery Directive (98/37/EC) reference a document that has been referred to as a declaration of incorporation. That might be what your vendor was referring to. The wording in the directive indicates that it is for machinery that is intended to be incorporated into machinery or assembled with other machinery I also have an example of this document (from a UL Seminar on CE Marking) if you want to take a look at it. It states that this type of machinery is not allowed to be put into operation until the end product machinery has been properly evaluated. Let me know if you want me to e-mail you a copy of the example declaration or the applicable pages from the directive. Hope this helps! Best regards, Mark A.

Re: Pre-amps for EMC Use
I have used Miteq or Mini-Circuits preamps with a custom box (Al project box) and a 15Vdc regulator. These had around 20dB of gain which was sufficient at 3 or 1 meter for most frequencies between 1 - 18 GHz. The exact model that we used has been discontinued though and I am unsure if a replacement has been designed. I believe the cost for these preamps was between $1k - $3k, so they were pretty cheap if you are handy enough to build your own box to protect/power it.

Re: Certificate of Incoorporation???
Hi Andy, A certificate of incorporation is what should be issued with a sub-assembly that cannot operate on its own, and will be incorporated into a larger machine once shipped into the EU. See the machinery directive 98/37/EC, article 4, para 2, for the requirement for an article of incorporation, and see annex II, section B for the information to list on the article of incorporation. In general, an article of incorporation is exactly like the DOC with these exceptions: 1. At the top, you list Article of Incorporation instead of Declaration of Conformity :-) 2. You do not have to list any directives or standards, as the item is not required to comply with any AT THIS TIME. 3. You must include the statement This machine must not be put into service until such time as the machinery into which it is incorporated has been declared in conformity with the provisions of the Machinery Directive 98/37/EC, or something very similar. Note that an interesting point is that at the time of import, the equipment does not have to comply with the machinery directive nor any technical standards. It must comply eventually, when the equipment is incorporated and the larger assembly is declared to be in compliance. The machine also should not be CE marked under the machinery directive when this route is used. An second interesting aside is that while the machinery directive has provision for a declaration of incorporation, the EMC directive and LVD directives do not. A purist would insist that while MD compliance can be delayed, compliance with the others can not. However, in practice, we delay compliance with all three if needed until incorporation time.

Andy, Certificate of Incorporation usually is the piece or paper from the Secretary of State of the state your company is incorporated in as a business.

Re: Conducted Emissions Test in Telephones
In a message dated 6/28/01, Geoff Lister writes: EN55022:1998 section 9.5 indicates that measurements must be made on telecommunication ports, and covers, in great detail Hi Muriel: Geoff has provided a succinct answer to the question you posed. I just want to add that you will also have to test for immunity per EN 55024 if you plan to CE mark your product. This standard includes about seven different immunity tests (static discharge, lightning, etc.). Of the tests included in EN 55024, perhaps the most difficult is the conducted immunity test. For this test, common mode RF signals of 3 VRMS, 150 KHz to 80 MHz, are applied to the phone line. The RF carrier is 80% AM modulated at 1 KHz to simulate an AM radio station. Limits are placed on the amount of demodulated 1 KHz that appears on the phone line and in the handset. My experience with this new test suggests that most conventional telephone designs will have difficulty passing. You may need to add some special filtering in strategic locations order to pass.

RE: Reconditioned Equip
No, if the equipment was placed on the market prior to 2001 and was compliant with the requirements in place at that time. Refurbished equipment may be resold forever based upon the CE requirements at the time is was placed on the market. Richard Woods -- From: Bill Wilson [SMTP:wilsonassocia...@mediaone.net] Sent: Thursday, June 28, 2001 9:13 AM To: Treggers Subject: Reconditioned Equip I'm sure this questioned has been asked and answered before. If I recondition equipment in the UK that is CE Marked to pre 2001 EMC requirements and I sell it later this year, do I have to retest to the new 2001 EMC requirements? Any input will be appreciated.

Re: Examples of EMC problems in the real world

RE: Conducted Emissions Test in Telephones
Muriel, EN55022:1998 section 9.5 indicates that measurements must be made on telecommunication ports, and covers, in great detail how this should be done. Section 8.2 starts with The operational conditions of the EUT shall be determined by the manufacturer according to the typical use of the EUT with respect to the expected highest level of emission. So, you should check both at standby and active for the highest levels. Other CISPR 22 related specifications may differ, but you will need to test for countries using the EN specs.

RE: Voltage Range in Asia
Judd, Thanks for the comment. We intend to keep the information at its present site until a more permanent site is available. This new site will be provided by the emc-pstc folks. It is not in operation yet but stay tuned as I'm sure they will announce it when it does happen. Like I said though, we intend to keep it where it is until then. Thanks to Jim Bacher for his support.

It would be a higher performance server. Would this be OK with you? Would you mind keeping it up to date once it is there?
