Standards for Products Going into Petro Chemical Environments
If I wanted to sell an electrical/electronic device (like a PLC) into a Petro-checmical environment (pulp/paper mill, steel mill, etc.) what standards would be applicable to ensure the product can withstand such a harsh environment over a long period of time? This device would be installed in a control room located inside of one of these environments (i.e. not in the harshest spot of the factory, not the cleanest).

Obtaining Lab Accreditation
Hello Group, I have been tasked with obtaining A2LA accreditation for my internal (first party) lab. We have about ten technicians, perform all standard suite of IEC EMC tests along with vibration, shock, bump and environmental (cold, dry heat, damp heat) testing. I have attended ISO 17025 training but still have some questions. I'm wondering if there is anyone out there who has experience with ISO 17025 of ISO Guide 25 lab accreditation who can answer these questions: 1. Roughly how long did it take you to obtain the accreditation start to finish? I am thinking that it will take about one year. 2. Would you mind sharing the contents of your Quality Manual? 3. Is there a group or organization around that one could obtain example Quality Manuals from? 4. What were some of the benefits and reasons for obtaining lab accreditation? Was it worth while and why? Thanks for your input. Don -- This e-mail may contain SEL confidential information. The opinions expressed are not necessarily those of SEL.

RE: Revised EMC standards and CE Declarations.
Ghery, Is it a absolute must to test? If you have reasonable justification that your products are compliant (the new requirement is wimpy), why not just document your reasoning and continue to sell product after the DOW? Regards, Don "Pettit, Ghery" on 11/27/2001 02:09:59 PM Please respond to "Pettit, Ghery" To: "'jasonxmall...@netscape.net'" , emc-p...@ieee.org cc:(bcc: Don MacArthur/SEL) Subject: RE: Revised EMC standards and CE Declarations. Jason, You are correct. All products placed on the market in the EU must be tested to the latest standard once the magic date (DOW) for the new standard is reached. Also, keep in mind that if a product specific standard is published it takes precedence over the generic standard and the generic standard no longer applies to the product family. For example, EN 55024:1998 is the product specific immunity standard for ITE, so EN 50082-1:1997 is not used for these products. This is one more example of why I refer to the EMC Directive as The EMC Professionals Employment Act of 1989.

Hi all. EN 50082-1:1992 was replaced by EN 50082-1:1997. According to the newapproach.org website, from 1/7/2001 the old version no longer allows one to presume conformity to the EMC Directive. Does this mean I need to retest all equipment to the new standard before I can declare conformance? My guess is YES.

Manufacturing Hipot Testing
Dear Group: A Hipot standard which we must run for CE compliance requires that circuit-to-circuit and circuit-to-ground testing be performed on a routine basis. The test is applied for 10s. The products I deal with have many circuits (Inputs, outputs, etc.) so test time is excessive . To speed test time the standard allows for grouping of similar circuits and decreasing the test time to 1s (with increased voltage). There is a problem with the grouping method because faults between circuits in the group are masked. A better way of performing dielectric strength testing would be to automate a process where each individual circuit is hipot tested to ground for 1 second. The problem is that this method doesn't match what the CE standard requires. Some of you have probably been in similar circumstances. What did you do? What do you suggest? Do I meet the standard no matter the cost? What is the risk of having my CE Mark pulled and perhaps my company sued if I do not meet the entire standard?

Philosophy for old designs with new requirements.
I would appreciate some feedback on the following: Let's say I have several existing designs which meet the requirements for CE Marking today (EMC & Safety). What is the requirement for these existing designs when a new standard comes out, let's say six months from now? I think the older designs must be re-designed to meet the new requirements or not be sold into the EU. Is this true? What ammunition is out there for me to prove this fact to the higher-ups?
