Bill, "Appropriate" covers a lot of ground. Especially since you didn't specify your market (country, equipment category (e.g. semiconductor machinery)). You also didn't mention if you are interested in compliance - or if you're just looking for a little light reading. If you're looking for international standards try searching: http://www.iec.ch/ Since you have not specified I'll just stick with the general standards (there may be a more suitable product family standard). IEC 60204-1 (1997-10) Electrical equipment of industrial machines - Part 1: General requirements Provides a requirement stating that machines must be capable of correct operation at 40 degress C (humidity <=50%). This requirement can be altered however by agreement with your customer (see Appendix B). You might also consider the following standards: IEC 60068-2-56 - Ed. 1.0 - Bilingual Title: Environmental testing - Part 2: Tests. Test Cb: Damp heat, steady state, primarily for equipment Publication date: 1988-12 TC: 104 (ENVIRONMENTAL CONDITIONS, CLASSIFICATION AND METHODS OF TEST) Pages: 15 Price: 36.00 CHF (price code : H). Abstract: Determines the suitability of electrotechnical products, principally equipment, for use and storage under conditions of high humidity. You would also need the IEC 60068-1 as well. I imagine a few different tests plans are described in the standard. IEC GUIDE 106 (1996-07) Ed. 2.0 CHF 27.00 17 pages Guide for specifying environmental conditions for equipment performance rating This standard is listed in the bibliography of the IEC 60204 Hope this helps.
