CISPR 11, “Industrial, scientific and medical equipment – Radio-frequency disturbance characteristics – Limits and methods of measurement,” has been updated. The new Edition 6.0 is available in paper format, for pdf download or as a redline edition from Document Center Inc. This new 2015 update replaces both the Edition 5.0 from 2009 and it’s Amendment 1 from 2010. It is a technical revision.
Your CISPR 11 is the go-to document for emission limits for RF disturbances in the frequency range of 9 kHz to 400 GHz for what’s termed ISM equipment (Industrial, Scientific and Medical.) This type of equipment is designed to generate and/or use locally radio-frequency energy. IEC notes that this equipment can include RF lighting equipment and UV irradiators, however induction cooking appliances are covered in CIRPR 14-1.
What’s new in CISPR 11 2015? Here’s what IEC says:
“It introduces and permits type testing on components of power electronic equipment, systems and installations. Its emission limits apply now to low voltage (LV) a.c. and d.c. power ports, irrespective of the direction of power transmission. Several limits were adapted to the practical test conditions found at test sites. They are also applicable now to power electronic ISM RF equipment used for wireless power transfer (WPT), for instant power supply and charging purposes. The limits in the range 1 GHz to 18 GHz apply now to CW-type disturbances and to fluctuating disturbances in a similar, uniform and technology-neutral way. For these measurements, two alternative methods of measurement are available, the traditional log-AV method and the new APD method. It has the status of a Product Family EMC standard in accordance with IEC Guide 107, Electromagnetic compatibility – Guide to the drafting of electromagnetic compatibility publications (2014).”
For many of our customers, just knowing the basics of what types of changes are in a document is not enough. With the stringent requirements of GAP analysis these days, having a redline edition makes the line-by-line analysis of a new update much more exacting. This is why IEC is making a redline edition available for CIRPS 11. This copy has all the changes from the previous edition to the new one marked clearly. However, you do want to know that this redline edition is not an official edition of the document. It is being providing for your information only. You still need the official Edition 6.0 copy in order to be compliant.
