Request for Standards

I read in sci.electronics.design that corlioni1976 wrote (in ) about 'Request for Standards', on Thu, 20 Jan 2005:

There are no free downloads of any of these. The DIN standards you can buy through the DIN web site. The IEC standards you can buy through the IEC web site. But your list has a large number of errors:

2) IP43 is a code defined in the next standard;

3) This is now IEC 60529;

4) This is the same as 3). You don't need both; 6) 'Class B' is something defined in EN 55081-1, but this standard is out of date. You could buy the standards from BSI as BS EN 50081-1 and - 2, but you may need the later BS ENs in the 61000-6 series instead;

8) From BSI as BS EN 55022. Be careful! The revision status of this standard is a confusing mess;

9) You can buy this from the FCC web site;

10) See 6); the same advice applies;

11) to 15): These are all out of date and indeed some of them were never published. They have all been replaced by standards in the IEC/EN/BS EN 61000-4 series.

I suspect you need more detailed advice before you spend about GBP1000 on those standards. You can get further (limited) free advice if you email me at:

The good news is that nothing is compulsory.
The bad news is that everything is prohibited.

Hi Corlioni,

Many standards are not available for download but must be purchased. IEC, or organizations such as IEEE and VDE are good places to start. Remember that standards can be expensive, depending on volume. I paid around $200 just for one (IEC601). Sometimes there are member discounts but on this one there wasn't.

It is free.

Presumably it's free since it's a US government regulation ( law ) and not strictly a standard as such.
