I guess to measure the cost of compliance; you certainly need to understand the cost of non-compliance.
Safety, with regard to reputation, conscience, law suits, sleeping well at night, jail time, etc. EMC and Radio, with regard to quality, reputation, harmony within society, etc. In the USA, Canada and Europe, I see very real examples of how poor compliance rates do lead to a tightening in the requirements. So, you could also consider it an investment. Just a thought. :-) Michael. Michael Derby Regulatory Engineer ACB Europe -----Original Message----- From: Richard Nute [mailto:[email protected]] Sent: 30 March 2012 12:24 To: [email protected] Subject: [PSES] "Compliance costs too much." I once worked with an EMC engineer who measured the performance of himself and his time by the cost of the components that were used in the equipment solely for the purpose of EMC control. His objective was to reduce the cost of compliance by advising designers of careful layout so as to minimize the need for EMC components. Safety is a bit different because many safety components are also functional components. Nevertheless, a ground wire can be eliminated if double-insulation is employed. In this example, a cost trade-off between the power cord and the extra insulation. But, these days, most primary circuit designs are indeed double-insulated as transformers simply don't use internal shields. Enclosures... only needed for primary circuits and secondary circuits exceeding 30 V. (Yes, you still want an enclosure, but not for safety!) Etc. So, compliance should not cost too much. I look forward to your comments on compliance costing too much.
