IMO the same logic applies >to emissions. No-one is advocating wilful ignorance. I pointed out that the situations with safety and EMC are somewhat different. For safety, it may well be necessary to investigate temperatures, **whoever** puts the products into the rack. With regard to leakage current, the total value of current does not depend on whether the products are in a rack or not. > >IMO, even if one is not legally required to test, -- as in the sale of >components direct -- one might well find himself in violation of >implied warranty of serviceability should a customer find himself >forbidden because of emissions to use what we sold him. I really think this is beyond sensible. The emission limits have been set, **taking into account that one product is very rarely use in an environment where there is no other product operating and emitting.** The overall level of emissions cannot possibly be affected by whether it was the user or the manufacturer that put a set of compliant products into a rack. -- OOO - Own Opinions Only.
