Hi folks,
i have some questions abaut international standards.

If a company produces electronic products for the international market,
to which standards have this product to complie ?

Who controls this ?

Start with the ISO and IEC standards and then look at those applicable in
Europe, USA, Australia, NZ and Russia. You will find that most of them are
closely related to the ISO (although some of the RF bands may be different
for EMI testing purposes). Certainly many of the European standards are
drafted close to the ISO/IEC standards. You will have to purchase many of
these standards but a trip to a decent library should assist you determine
the ones that are most suitable for your product. I know that if you happen
to mention what your product is others here could provide a reference for
the exact standards that you should comply to.

Hi,

For instance, the plugs in the US or Australia could not even make it to
market in Europe, they are not safe enough. I mean, it's way too easy to
touch the metal part if the plug is not fully inserted.

I notice that most 3-pin sockets in the U.S. have the ground pin
at the bottom which is opposite to the U.K. norm. From a safety angle
I would have thought this to be a 'no-no'. Turning it round would
put the ground pin where 'little fingers' and dropped objects would
be most likely to make contact instead of the live pin as now.

Am I missing something then, apart from numerous brain cells?

You're not missing anything. I don't think there is a "standard" nor

is it written into code that the ground pin shall be on the bottom. It
just sorta works out that way. A my POE the ground pins are up, as you
expect. Indeed they're up on both sites (different states) I've worked
in, though an informal poll of sites across the country showed that
some were up and some down, by edict even. It seems that cords are
made assuming the pin is down though. With the pin up some tend to
work loose from the wall.

Yeah ? Just curious.

In the UK we have the ground pin *up* by default. Irrelevant when you use a
power strip extension though.

Oh and our power pins are often sheathed for much of their length too as of
some date well in the past, although this seems to be optional.

YOU CONTROL THIS. FIRST IF YOU DONT KNOW WHICH STANDARD OR STANDARDS
YOU NEED TRY AND GET AHOLD OF UL, CSA OR TUV AND SEE IF THEY CAN HELP.
NEXT YOU CAN LOOK UP SAFETYLINK TO CE, CB SCHEME, EC, IEEC, AND CHECK
OUT STANDARD SECTIONS. IS YOU PRODUCT FOR CE OR OTHER COUNTRIES. THEN
YOU WOULD NEED TO CHECK OUT CB TYPE COUNTRIES CHINA, JAPAN, KOREA, ETC.
OR CHECK OUT PRODUCT SAFETY TEST LABS IN YOUR AREA MAYBE THEY CAN HELP.
IF YOU STILL CANT FIND HELP YOU CAN EMAIL ME AND I WILL TRY AND HELP.

I once dropped a metal ruler on a plug that was not all the way in it's
socket. Caused a loud band, tripped the breaker, and burnt/melted
parts of the plug and ruler. Ever since, I've wondered why they don't
put the ground prong up.

I read on another discussion board that electricians (in U.S.) tend to
put the ground plug up on switched outlets, and down on unswitched
outlets. It's just a convention, to make it easy to tell which outlets
are tied to a switch. It's not dictated by any code, though, and I
notice that a switched outlet in my house has ground pin down like all
the rest.

Receptacle orientation ("does the ground prong go up
or down?") is an age old debate. Here's my solution:

---------
| 0 |
| | | |
| |
| * |
| |
| | | |
| 0 |
---------

:)

Actually, whatever points either side of the debate
make are moot when you consider that a receptacle
can be installed sideways. Then the debate will be
"does the ground prong go left or right?" :)
