12、shall be subject to the applicablerequirements of the Standard for Key Locks, UL 437 as specified in Table 4.1 of UL 294.RATIONALE FOR DECISION:The decision for this change was made based on the intent of UL 294 to provide a tiered performanceapproach to multiple categories. In order to allow for ti

13、ered attack levels in single point locking devices,Section 33.2.2 and Table 4.1 are being modified to align the tiered destructive attack tests with a tieredkey lock attack tests per UL 437. As UL 437 does not explicitly detail the tiered approach in the sameformat as UL 294, an additional line was

14、added in UL 294 Table 4.1 to address the discrepancy.Copyright 2014 Underwriters Laboratories Inc.UL, in performing its functions in accordance with its objectives, does not guarantee or warrant thecorrectness of Certification Requirement Decisions it may issue or that they will be recognized or ado
