The revisions dated August 17, 2007 were issued to incorporate the following new and revised requirements and to reflect the August 17, 2007 ANSI recognition of the standard:
(1) Addition of test requirements to address corrosion protection for zinc plated, ferrous metal fittings for use with liquid-tight flexible metal or nonmetallic conduit when installed directly in earth
(2) Addition of requirements when using a direct bearing setscrew type fitting intended for installation with extra-reduced-wall flexible aluminum cable or conduit
(3) Addition of alternative torque test to verify compliance of attachment requirements for conduit body covers of conduit bodies
(4) Clarification of thread engagement requirements for fittings and conduit to align the requirements with the corresponding requirement for threads in UL 514A, Metallic Outlet Boxes
(5) Modification of installation requirements for bushings for metal studs to prevent damage to conduit, tubing, or cable
(6) Addition of assembly torque requirements to allow manufacturers to specify torque assembly torque where specific assembly techniques are required
(7) Modification of marking requirements to require that a fitting for armored cable or aluminum sheathed cable be marked with the smallest and largest cable diameter for which the fitting is intended to be used
(8) Deletion of marking requirements for fittings of the 1-1/2 (41) or larger trade size for use with liquid-tight flexible metal conduit to clarify that these fittings are suitable for use as a grounding means
(9) Clarification of marking requirements for expansion fittings intended for use with external bonding jumpers to specify that the requirements are not applicable in Canada and to delete the word "outdoor" as the requirement applies to all expansion fittings
(10) Modification of sample requirements for the wet-locations test for compression type fittings for use with EMT and installed in wet locations
(11) Clarification of ultraviolet light and water test to specify that samples are to be tested in accordance with xenon arc exposure Type A
(12) Modification of requirements applicable to expansion fittings to specify that the resistance test for expansion fittings does not apply in Canada, and that the resistance test and reciprocation test does not apply to an expansion fitting installed with an external bonding jumper or integral internal bonding jumper
(13) Addition of tests to address sealants used with conduit, tubing, or cable exposed to varying temperatures
(14) Deletion of references to the term rain tight to align with current terminology used in the National Electrical Code
(15) Modification of carton marking requirements to address fittings intended for installation with extra reduced-wall flexible metal cable or conduit
(16) Changes to correct references and to clarify requirements
