Experts: One of my clients has a process tool for use in a controlled EMI environment, that incorporates a plasma generator for cleaning housings before glue is applied. The plasma electron density is typically around 1011 cm-3
There are two parts to this question: * an EMC test house told them that because it had a plasma generator it would need to be EMC tested to EN 60974-10 which is for arc welders and associated equipment. This scope of this standard says, in part, "IEC 60974-10:2014 specifies a) applicable standards and test methods for radio-frequency (RF) emissions; b) applicable standards and test methods for harmonic current emission, voltage fluctuations and flicker; c) immunity requirements and test methods for continuous and transient, conducted and radiated disturbances including electrostatic discharges. This standard is applicable to equipment for arc welding and allied processes, including power sources and ancillary equipment, for example wire feeders, liquid cooling systems and arc striking and stabilizing devices." o So the question is to continue to use EN 61000-6-2 and EN 61000-6-4 if classified as machinery, or EN 61326-1 if classified as MCE equipment, or have a separate report done for EN 60974-10? o The individual tests still use the EN 61000-4-x series, but with some modification. It also requires testing to EN 61000-3-2, and 3-3, which would normally be done for machinery or MCE. * The second part is safety evaluation of the complete product. There is nothing in EN 61010-1 or EN 60204-1 that has the word 'plasma'. Operator safety meets requirements. I am not aware of any special consideration that needs to be given to the plasma generator. In fairness I have not contact the plasma generator manufacturer yet to see what if any standards their units are, I assume, approved to. Thought and comments greatly appreciated. - ---------------------------------------------------------------- This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
