This new edition of ANSI/UL 62 has been published to update the ANSI approval of the standard and includes:
Revised reference publications.
Removal of specific material requirements for tape or yarn used as a separator.
Clarified construction requirements for range and dryer cords and added mm2 size designations.
Clarified substitutability of materials of higher temperature ratings.
Changed "%" to "percent" and better defined how diameter (D) under braid is to be used and measured.
Added a requirement for testing of bare copper wire shields with thermoset insulations.
Clarified the required flame test requirements for SPT cords used in Mexico.
Added HSJW and HPNW to permit use of heater cords exposed to sunlight and water|.
Revised wording to clarify the requirements for insulations used in duplex units of elevator cables.
Added NISP-1, NISP-2, NISPE-1, NISPE-2, NISPT-1, NISPT-2 to clarify that these types are not required to be subjected to the Tightness of Insulation test.
Clarifed the AC Leakage Current Test for Low Leakage Cord.
Clarified oil resistant types that can have an "O" in the type designation and those types that are required to be oil resistant, but are not permitted to have an "O" in the type designation.
Added a requirement for caution marking on single conductor CXWTc.
Added new types CXTW-S and CXTW-IS that can be shown to have the equivalent strength to the breaking strength of a 2-conductor, twisted 22 AWG CXTW (UL 588, 13.2.4), or to the breaking strength of a single conductor CXTW twisted with a supporting rope (UL 588, 81A.2).
Added the "-X" suffix for Type CXTW in sizes smaller than 22 AWG that are equivalent in breaking strength to a 22 AWG,
Added Types LXT and LXTW used in decorative lighting products, and added "-X" suffix for constructions that are equivalent in breaking strength to 22 AWG.
Added testing and marking requirements for cords incorporating the overall braid.
Added the missing Spark Test voltage in Table 46.
Added 20 AWG DPT and DPTW types.
Added grounding conductor size for cables containing 9 AWG circuit conductors.
Added 1000 V electric vehicle cable.
Clarified the definition of Neutral Conductor.
Added thermoplastic oil resistant compound like an SVTO as an optional jacket for elevator cables.
Added Annex D to provide a list of cord types by country.
Added a note to Table 22 for single conductor CXWT used in two conductor CXWT twisted lighting strings.
Revised Table 20 to allow SPT-1W and SPT-2W for use in Canada and Mexico.
Added applicable tests for conductors containing fibrous strength members.
Added harmonized type designations for Flexible Cords and Cables and Electric Vehicle Cables using TPE insulation and jacket.
Added the abbreviation "w/thrd" to shorten the required marking for those products containing a thread in the conductor.
Revised the Cold Impact Test temperature required on all electric vehicle cables.
Added Type YXTW for use in year-round lighting strings.
Revised requirements for data and signal conductors used in Electric Vehicle Cables.
