We are facing the same challenge. The way we address it is essentially the TCF route, including a Competent Body involvement. Our installation contains some equipment qualified for residential environment only, which wouldn't meet the industrial immunity test levels by itself. We add filters in the power distribution path, shield the data paths, and so on, to pass some of the required tests. For some other, we use exceptions permitted by the standards. For example, an installation which draws more than 16A, fed by a transformer sub-station dedicated to that facility, can be exempted from certain immunity tests. We also had to buy industrial-grade equipment for parts of our installation where commercial one would have done the job. If you need more info, we can continue this discussion via private email.
Alexandru Guidea CAE Inc. -----Original Message----- From: Gordon,Ian [mailto:[email protected]] Sent: Tuesday, April 30, 2002 4:57 AM To: 'IEEE EMC & SAFETY PSTC' Subject: CE MARKING A SYSTEM Can anyone advise the course of action in applying a CE mark as regards EMC to a system some of whose component parts are not built by us and whose D of C's claim light industrial immunity. However, the system has been running in very harsh environments e.g. plasma etch applications at customer sites and we wish to claim industrial level immunity for the system. The system is obviously "fit for purpose" in the intended environment. We have performed radiated testing to this level on the whole system. Unfortunately if we surge test these "light industrial" components which form part of the system we are certain they will fail at the appropriate levels. One component is an "industrial" PC. Does anybody have any suggestions as to what action to take to allow us to apply the CE mark and claim industrial immunity?
