Re: Standards history

You're remembering Conrad Maheux, a major player in the integration of the North American standards and the transition to IEC. For a long time he ran Canadian Business Equipment Manufacturer's Association, later to become ITAC. Always had his bucket of commas handy. Fondly remember the dinners at A

Hi Derek Sorry, but I feel compelled to provide another point of view-about US products failing! I came to the US more than 30 years ago and quickly subscribed to Consumer Reports, which I always use as a guide to buy just about any appliance. Perhaps, as a consequence, I have had a totally differe

Bob, We test our product at a local accredited test house for CE and FCC pt 15. Initially we had certificates for passes against the various EN specs and a full FCC report with photographs. Because we make telecommunications products, most countries require a detailed telecomms submission, wi

<$0.02> I just thought I'd add my two cents worth. It's sometimes all too easy to forget WHY we perform these tests. While we are trying to comply with written requirements in order to "pass", we are also trying to ensure product performance in the real world, which can be a very hostile place fro

All, Jim Hulbert (Pitney Bowes Inc) is correct regarding his comments on ACA accepting EMC reports from a laboratory or organisation which is accredited by either A2LA or NVLAP as this is recognised by NATA (National Association of Testing Authorities Australia).

Derek, thanks for the TCF information. This brings up another question I have concerning EMC test reports in general. When there was basically only the Europe and the U.S. to be specifically tested for, we produced two test reports tailored to these areas (graphs and limit lines, test setups, l
