I tried to send a message out on 9/6 re. Doug Henderson's question on standards dealing with acoustic pressure for medical lab equipment. I got back an undeliverable message with addresses from outer space (at least I didn't type them). Anyhow, that leaves me without Doug's address, but I hope he monitors and gets this.....
I suggest you reference IEC 1010, Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use. Clause 12.5.1 indicates that equipment shall not produce a sound pressure level above 85 dbA when measured both at the operator's position and at 1 meter from the position with the highest sound pressure. I have been away from IEC 601.1 (Medical Electrical Equipment) for awhile, but my last recollection is that requirements were under consideration only and currently not included in the standard. Hope this helps. _________________________________________________________________ Bob M. Miller Underwriters Laboratories Inc.
