UL 498 covers attachment plugs and receptacles and section 114 gives the specifics on the plug retention tests. For UL, retention is tested with a whole plug and there is no requirement for testing each pole separately in this standard. If the receptacle is designed for either a two wire or three wire plug, it must be tested with both.
For non-locking receptacle, the plug must be held in place by a pull of no less than 3 pounds force (13 N). It must release with a pull of no more than 15 pounds force (67 N). This test is not applied to locking receptacles.

[email protected] m To: [email protected] Sent by: cc: owner-emc-pst Subject: CSA C22.3 #42-99 [email protected] 11/09/00 11:53 PM Please respond to rbusche I had a question posed to me by a fellow engineer with regard to the design of an electrical outlet to be used in ITE equipment. He is following the requirements identified in CSA standard C22.2 #42-99 where each pole and ground pin is individually subjected to a weighted pullout test. The question was whether or not this is also part of the equivalent UL requirements for electrical outlets. An engineer from a reputable power cord manufacturer told him that UL did not require this test. Unfortunately I have no expertise with either standard and could not help. Could someone let me know what the equivalent UL standard is and whether this is a true statement. If someone could contact me off line I would appreciate it. Thanks in advance...
