Hello Eric, Some companies have environmental test programs that subject their products to all types of power line conditions that are not covered in regulatory requirements. As far as line voltage tolerance testing, this depends on the specifications you publish externally for your products. However, what tolerance you test to internally may be greater than what you publish with a product specification.
It just so happens, when I was with the old Hewlett-Packard, we usually tested to +/- 12% for test and measurement products when the published tolerance was +/- 10%. However, these products were intended for light industrial and laboratory environments. Finally, to the best of my knowledge, I haven't heard of Japanese line voltages dropping below 90 Vac.

For safety we are testing up to - 10%: 90 V. However for some situations in Japan , it seems you can even expect 85 V. So we are planning to define a general rule that a product for Japan must handle 85 V. Is this low voltage rule known or common use in your company? best regards, Van Compernolle Eric Reliability Manager Barco Projection Systems Noordlaan 5 8520 Kuurne Phone:+32 56 368 373 Fax:+32 56 368 355 mailto:eric.vancomperno...@barco.com http://www.barco.com > ------------------------------------------- This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.
