To all,
I need some help in determining if there are any actual quantifiable hazards being presented to humans when exposed to the radiated field of the radiated immunity test such as IEC/EN 61000-4-3 or IEC/EN 61000-6-1 inside of a closed shielded or anechoic chamber. I’m asking anyone in the group with experience performing this test if they know the answer(s). Most test labs that I am aware of perform this test mandating that no one be in the chamber during testing. Is it simply normal practice to keep people out of the chamber during this test and not wanting anything in the chamber that might impact the field uniformity, or are there actual potential hazards associated with this testing? I have searched extensively for any documented requirements, restrictions, etc. from various agencies that I believe would be concerned with that, but to no avail. A concern has been floating around here for some time about the hazards to a human being that would be in close proximity to the generated EMI of a radiated immunity test. With some products, manual operation manipulation is needed to exercise portions of the product during this testing, which is where this question originates. The concern here relates to the proliferation of cases associated with close proximity to humans and any legal/ perspectives due confining a human in fully shielded and/or anechoic chamber during this test. To that end and in the USA, does OSHA impose any restrictions with this particular type of testing? Are there any maximum permissible exposure limits for this testing environment? If so, at what field intensity(ies) will precautions need to be taken? If you know of any references to any regulations, requirements and/or restrictions, please be kind enough to provide them, web links would be especially nice. All I need are references and if I need to, I will purchase them. Whatever could be provided would be greatly appreciated. I look forward to your reply.
