Hi,
I have a question on clause 6.3 and clause 1.4.11 of IEC60950-1.
6.3 Protection of the telecommunication wiring system from overheating
Equipment intended to provide power over the telecommunication wiring system to
remote equipment shall limit the output current to a value that does not

Some locations in China, particularly those near Shanghai, require
certification from the Shanghai Research Institute of Chemical Industry
(SRICI).http://www.msds.gov.cn/index.aspx?menuid=19type=introductlanmuid=98language=en
I can’t point to a specific regulation. As far as I know, this
All,
Since I move between equipment types regularly it's a good time to
review the EU Directives that apply to ITEq and confirm which are needed on
the DoC.
Of course the LVD has ben applicable all along as has bhe EMC
Dirctive. Please confirm the date the RoHS is a CE DoC
RoHS 2, 2011/65/EU, became effective 3 Jan uary 2013 as a CE marking directive.
Different scope extensions become effective through 2019. More substances are
under consideration for restriction; some reports on this are due in the summer
of 2014, as I recall.

Esteemed body of knowledge,
Today I learned about a China customs regulations requiring UN38.3 T1-T8
certification for all lithium batteries: Lithium-ion, Lithium-polymer, and
lithium-metal. This is applicable to single use as well as rechargeable
batteries. The certifications cannot be
Hi Richard,
Yes, we have been dealing with this for awhile. For China shipments, the
testing must be done by one of the government approved labs. Even as a test
lab, we have to use the government lab down the street. If your shipment does
not have the correct certificate with it, the
Jody,
Is it the case that you can, in the US, do the requisite crush tests etc, of
UN38 completely within you own facility and self verify the ATA requirements,
and do other regulators also accept in house data - rather than independent
verification? The typical (and there are only a small
Yes, Richard, this is a fun one! It is related to a so-called
“safe-for-transport certificate” (very rough English translation). If an item
looks like it could be a DG you need to get a cert saying that it is not. Li
batteries are particularly difficult.
Only certain recognized labs/companies
Gary,
China is the only region in the world that I am aware of with such regulations.
I agree with your assessment of the rest of the world.

Hi, group
I plan to measure the servo motor for emc test
so i looking for a device that can be to measure the Immunity in IEC
61800-3 is a relevant standard
Measurement immunity items is;
- commutation nothes (IEC 60146-1-1)
- Harmonics ralating to IEC 61000-2-4
- Voltage changes, dips,
Thanks for John's reply
The contents of clause 6.3 and 1.4.11 of IEC60950-1 are moved to IEC60368-1 1st
edition
6.2.2.4 PS1
PS1 is a circuit where the power source, (see Figure 40) measured according to
6.2.2, does not exceed:
�C 500 W measured during the first 3 s; and
�C 15 W measured after
Kim:
It is usually best to start out in EMC testing by taking your device to a
local test lab and watching very closely what they do, how they do it, and
what they use. After you see it up close once, then you can determine if you
really want to develop the internal expertise and hardware
