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.

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

Kristiaan,
The EMC regulations in Australia allow compliance with any of the following
for IT type equipment:
a) AS/NZS 3548:1995 or AS/NZS CISPR 22:2002; or
b) CISPR 22:1997 + Amdt 1:2000 or CISPR 22:1997 + Amdt 1:2000 + Amdt

Eric,
The FCC will only allow the use of a loop antenna for E-field measurements
below 30MHz.
Hope this helps.

When I think of a network analyzer, I think of a device that injects a
signal into a network, and then receives the signal after processing by the
network using a receiver tuned to the original frequency. This type of
network analyzer rejects harmonics.

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.

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

approval, particulary if a product falls under a product type identified in
the CCC catalog? I

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

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

for display screens of the Cathode Ray Tube type in order to provide
