RE: New vs. Used Instruments

Mark In order to try to give some answers to your questions, we need to know what levels of testing you do for EMC, safety (etc.), i.e.: are they: a) full standards-compliance tests, in which case the equipment is often likely to be physically /or electrically damaged and may well not be

ATEX directive questions

Hello, All, In reviewing the ATEX directive(94/9/EC), it appears that a safety and control component (overload relay, circuit breaker)located outside of a potentially explosive environment which controls a process or equipment inside a potentially explosive environment must meet the requirements

RE: IEC 60601-1 Table 16

Hi Brian I think i misinterpreted your first post, sorry. The second edition of IEC 60601-1 do not deal with the determination of working voltages (the draft third edition deals with it in the same way as IEC 60950 ). It´s because the second edition is an old standard compared to the recent

RE: IE C60601-1 table 16

Brian, If I understand you question, you are correct. IEC 60601-1 second edition does not address any voltages other than rms and DC. The draft third edition does address peaks. It is up to you and if applicable the test house, how to interpret what the rms value is. NOTE: you can

RE: New vs. Used Instruments

Mark, I think it depends on the tests that are being conducted and the amount of degradation that this may cause to the equipment. If testing for emissions, I would think in general that there would be no issues. When testing for susceptibility, that may be a different issue, especially if the
