New IEEE C63.7 2015 Edition

IEEE C63.7, “American National Standard Guide for Construction of Test Sites for Performing Radiated Emission Measurements,” has just been updated.  The 2015 Edition is available now from Document Center Inc. in either paper format or for pdf download.  It can also be included in our Standards Online subscription service for multi-user access.  The EMC standard is ANSI approved (the document used to be known as ANSI C63.7).  It’s been updated so that it can be used with the latest edition of IEEE C63.4 (“American National Standard for Methods of Measurement of Radio-Noise Emissions from Low-Voltage Electrical and Electronic Equipment in the Range of 9 kHz to 40 GHz” 2014 Edition).

Why would you use IEEE C63.7?  The standard provides you with the requirements for building test facilities to measure radiated emissions.  The facilities will be appropriate for testing electromagnetic emissions in the frequency range of 30 MHz to 40 GHz.  It is intended to be used with the other C63 series EMC standards.

Is there only one option for this type of testing facility?  No, you have several options depending on the frequencies you’ll be testing.  For 1 GHz and below, you’ll get the requirements for an open-area test site (OATS) and a semi-anechoic chamber (SAC).  For 1 GHz and above, you can choose from an OATS with absorber material or a SAC again with absorber material, in a number of surface configurations (one of which is called a fully anechoic room (FAR)).

What are the changes in this new 2015 Edition for IEEE C63.7?  The committee has highlighted the following areas where updates have occurred:

  • OATS with weather protection coverage are now included.
  • New provisions are introduced for SACs and FARs.
  • There’s updated to grounding for radio frequency low impedance and for human safety.
  • Of course, the coverage of the document has been expanded from 1 GHz to 40 GHz.
  • Links to useful URL’s are now included.
  • Annex C has been added (it cites the occurrences of “test site” in the C63.4 and C63.5).
  • Annex D, the bibliography, has also been expanded.
