Agreed. ---------- From: Bob Brister To: 'Product Safety Technical Forum' Subject: IEC 950 5.4.9 Compliance criteria for 5.4... List-Post: [email protected] Date: Wednesday, February 05, 1997 11:02AM
Hello, My interpretation of the criteria listed in 5.4.9 is if, under simulated fault conditions, a hole forms in the enclosure, that is not necessarily a failure of the product to remain safe. Would you agree? The criteria seems to indicate that if there is no: 1. propagation of fire beyond the product. 2. emission of molten metal, and 3. no non-compliance with another section of the standard due to enclosure deformation, the product meets the requirements. This may not be a situation you care to allow from a product quality or customer satisfaction point of view, but it is not a failure of the product to comply to the requirements. Note: The assumption is that the product does comply with 4.4.2 and 4.4.3 Regards, Bob Brister Digital Equipment Corp. Bob Brister
