Re: CCC query
Ron-san CNCA has the rule of exemption to the CCC certification. It is No. 8th public notice of 2002 of CNCA. It is written in Chinese at the WEB of http://www.cnca.gov.cn/board/25.html I do not know where its English version is. Maybe Some agents for CCC in your country know it. The NO. 8 public notice says as follows; 1: Exemption 1; No need to apply for Exemption Products for Exibition use, Products for personal use carried with the person 2. Exemption 2; Need to apply for exemption ; Products to Study or to measure for producing products Parts for produce products for export only Products to use in the production line to examine the technology etc. Note) My translation is not so precise.

Re: Using a network analyser for EN61000-3-2 6 testing
I don't know which machine Derek has, but an HP4195 covers 5 Hz - 500 MHz, and it can be used in network analyzer mode, or spectrum analyzer mode. In network mode you can look at amplitude response, or amplitude and phase. If you are just wanting to measure harmonic currents drawn by some non-linear load, you could use the machine as a spectrum analyzer. It has RBW down to 1 Hz, per my recollection.

RE: 508kHz Intentional Radiator FCC
Eric, Robert is correct. The FCC requires the use of a loop antenna for measurements below 30MHz. The test distance required may put you in a bind, so Part 15 says for frequencies below 30MHz you can use lesser test distances and correct for the distance using a 40dB/decade conversion, as opposed to a 20dB/decade correction for frequencies above 30MHz. In addition, if by taking readings at a minimum of two different test distances you can prove a fall off ratio other than 40dB/decade, that can be used if documented in the report. The FCC does caution against making measurements in the near field. See Part 15.31 for further guidance.

Re: LCD Displays and Safety
I read in !emc-pstc that Crabb, John jo...@exchange.scotland.ncr.com wrote (in 1D4B655D707B2549AFCD8C686631657508AC2BC2@SGBDUN200) about 'LCD Displays and Safety' on Tue, 9 Sep 2003: I spoke to some committee members who seemed to think it was included because LCDs couldn't withstand the impact test ! I believe that was the prime cause for asking for the matter to be considered. The real issue, however, is whether there is a hazard in the LCD display that requires a degree of protection. I am aware of 2 possible hazards : High voltage present at the lamps within the LCD. In all the LCDs we use in our Automated Teller Machines (ATMs), I perform the limited current test and prove that the circuitry used meets the requirements for a limited current circuit. I would also conduct a short circuit test on the driver circuit for the lamp(s) - usually an oscillator feeding thru a transformer - but typically the power output is so low that the oscillator shuts down when a short is applied to the output transformer. The second possible hazard might be considered to be the chemicals present in the LCD. This has been the subject of some debate, the conclusion (based on information from LCD suppliers) being that there is no chemical hazard present. If you want any further details, let me know and I can probably recover something from my files. These are the results of the consideration, i.e. that the fragility of the LCD does not result in a hazard. -- Regards, John Woodgate, OOO - Own Opinions Only. http://www.jmwa.demon.co.uk Interested in professional sound reinforcement and distribution?

Re: Using a network analyser for EN61000-3-2 6 testing

This type of network analyzer rejects harmonics. There are some inexpensive network analyzers that use broadband detectors. These detectors receive the total signal coming out of the network, fundamental and harmonics. I know that Agilent Technologies (and probably others) now make network analyzers that can be configured to not only receive the fundamental of the excitation, but can be set to receive harmonics and offset frequencies (for testing mixers). I don't see what the advantage of using a network analyzer would be, unless there is some information to be gained by knowing the phase of the harmonics.

RE: Approvals Matrix
Alex, I think your matrix is a great idea but for Australia and NZ (Australia in particular) it is not that simple to cover all the compliance issues for your product categories in a matrix this simple. Joe Randolph was correct about PSTN standards for Australia and NZ (AS/ACIF S002 and PTC 200). Concerning safety, ACA TS001:1997 is the present requirement. This should change very soon however to allow compliance with either AS/NZS 60950:2000 or TS001. AS/NZS 60950:2000 = IEC 60950 + Australian national deviations. There is likely to be a brief transitional period where compliance with either standard is acceptable then TS001 will be withdrawn and compliance with AS/NZS 60950:2000 will be required. For Australia and NZ there is a large amount of information required to be added concerning your major categories: - If Modem - ISDN - If Wireless - Short Range - Bluetooth - If Wireless - Short Range - 433 MHz - If Wireless - Long Range - GSM - If Wireless - Long Range - CDMA Unfortunately I can not spare the time here to populate your matrix for you for Australia and NZ. Sorry. If you really want to work on adding more information for Australia and NZ please contact me direct.

CCC query
Hi to all, To those that are familiar with the CCC approval process and regulatory structure in China: I was just asked if it is legally possible to import shipment(s) of products into China w/o CCC approval, particulary if a product falls under a product type identified in the CCC catalog? I personally would advise against it, but management would consider it as anyone could well imagine. I could not answer this question, so I'm putting it to the expertise of the group. Is it legally possible? Please note that we are currently beginning this approval process and would appreciate knowing of any options that might be available until formal CCC approval is granted. I look forward to your replies. Best regards, Ron Pickard rpick...@hypercom.com This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.

RE: AS/NZS 3548 = AS/NZS CISPR 22:2002
Hi Kevin, I am aware of the situation in Europe but was not aware of that link between the Australian and European legislation. If my interpretation is correct, then I understand that I can ignore the Australian deadline of 21 Jan 2004 to use the AS/NZS CISPR 22:2002 standard (with more requirements) and just continue testing my products to EN55022:1994 (with lesser requirements). Is this assumption correct?

In July I prepared a table identifying what standards were acceptable in Australia and until what dates they were acceptable. I have attached this information in a PDF file. Please note it reflects the then official OJ listed cessation date for EN 55022:1994 (i.e. Aug 03). Now the OJ has officially revised this date to Aug 05 this standard would be acceptable until then.

RE: LCD Displays and Safety
You will have noted in IEC 60950-1 Clause 4.2.5 Impact Test, that it states the test is not applied to flat panel displays or to the platen glass of equipment (for example, copying machines). The waiver for flat panel displays appeared in the third edition of IEC 60950 - some time ago I trawled back through all my IEC committee papers trying to find the justification for this change - but couldn't find anything. I spoke to some committee members who seemed to think it was included because LCDs couldn't withstand the impact test ! The real issue, however, is whether there is a hazard in the LCD display that requires a degree of protection. I am aware of 2 possible hazards : High voltage present at the lamps within the LCD. In all the LCDs we use in our Automated Teller Machines (ATMs), I perform the limited current test and prove that the circuitry used meets the requirements for a limited current circuit. I would also conduct a short circuit test on the driver circuit for the lamp(s) - usually an oscillator feeding thru a transformer - but typically the power output is so low that the oscillator shuts down when a short is applied to the output transformer. The second possible hazard might be considered to be the chemicals present in the LCD. This has been the subject of some debate, the conclusion (based on information from LCD suppliers) being that there is no chemical hazard present. If you want any further details, let me know and I can probably recover something from my files.

As far as safety goes, you'll need to meet Hazardous location standards. The UL standards numbers vary by protection method used, UL 1203, 913, 1604, 2279, NFPA 496. Canada has similar requirements, in CSA 30, 157, 213, and E79, as well as incorporating NFPA 496. For the IECEx scheme, see IEC 60079 series, as well as some product specific Class 1, Zone 1 2 requirements in IEC 62086-1. Europe has EN 50284, 50015 through 50021, 50028. As far as EMC goes, When in doubt, err on the overkill side, especially when testing something that, when it fails, could lead to a news flash (pardon the pun), and nasty injuries. And of course, anything that disturbs the gasoline flow (even at one pump) raises the cost of gas by at least a nickel/gallon nationwide. (convert at will for petrol) Another fault to look for is billing - make sure the flow meter and billing amounts aren't disturbed. Or if they are, let me know which brand pump it is, and what frequency and power level stops/slows the billing.
