2、OT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL UL Standard for Safety for Thermoset-Insulated Wires and Cables, UL 44 Nineteenth Edition, Dated JANUARY 9, 2018 Summary of Topics This new edition of ANSI/UL 44 has been issued to: Add a reference to the Length of Lay

3、 test in UL 2556, CSA C22.2 No. 2556, or NMX-556-ANCE at 4.1.5.7 to specify how to determine the length of lay. Add ASTM B801, B901, and B902 to the reference publication section since these standards are referenced in Table 3. Expand the denitions in the glossary for “lled” and “unlled” require gre

4、ater specicity as to what materials beyond the characteristic constituent polymer(s) make up the ller. Revise 4.1.5.1.2 to replace 22 AWG with 24 AWG as the smallest size of aluminum strands that can be used. Revise 4.1.5.7(a) to permit compressed single input conductors to have other than reversed

5、direction of strand layers. Revise 4.1.6.1 to clarify that diameter requirements for conductor classes not referenced in Tables 5-10 do not need to be dened. Revise 4.1.7 to allow butt-spliced 8 AWG stranded conductors. Revise requirements align with the proposed new edition to Thermoplastic-Insulat

6、ed Wires and Cables, CSA C22.2 No. 75, UL 83, or NMX-J-010. Add a statement to 4.2.2 to clarify in Mexico, repairs to nished conductors are not permitted. Revise 4.5.2 to indicate Table 26 applies to both bare and insulated Equipment-Grounding Conductors. Revise 5.3.1.2 to cover cases where the cent

7、er strand consists of more than one wire and to include requirements for specimens taken from a center strand. Revise Long Term Insulation Resistance tests (5.4 and 5.5) and stability acceptance criteria for clearer interpretation of the LTIR test procedure and stability requirements. Revise the tes

8、t requirement for capacitance and relative permittivity at 5.6.1 to assign tolerances to the specied immersion temperatures. Revise the test requirement for conductor corrosion at 5.7 to specify the temperature and duration of the test. Add a country difference to the test requirement for hot-creep

9、elongation and hot-creep set at 5.13. Clarify section title for 5.14.2 to specify the requirement applies to XL insulation types only. JANUARY 9, 2018 UL 44 tr1UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL Revise the optional FV-2/VW1 vert

10、ical specimen test in 5.14.4.1 to clarify that the requirements apply only to the vertical ame aspect of the test and not the horizontal ame portion. Revise the optional weather (sunlight) resistance test in 5.15 to increase the exposure duration in Canada. Revise 5.16 5.17 to indicate that a wire t

11、hat complies with the requirements for PR II also must compy with those for PR I. Revise the optional marking requirement for gasoline and oil resistance, 5.17.1. Revise requirement in 5.18.1 for 1200 lbf crush on 14 AWG specimens “and/or” 1800 lbf crush on 2 AWG specimens to include circumstances f

12、or testing both specimen. Revise 5.22 to specify the projected elongation requirement applies to both the insulation and jacket. Add a reference to Table 5, Conductor diameter and cross-sectional area in 6.1.4 to ensure the correct mm 2 value is marked. Add new 6.1.5 to specify that wire is required

13、 to be marked when other than those with ASTM Class B, C or SIW stranding. Revise optional ame test marking requirement in 6.1.10.1(d) to include the option to use FT4/IEEE 1202 marking. Revise the note that follows 6.1.10.1 to make it clear that the CEC species this only for certain conditions and

14、cables. Add a note to 7.1 to indicate In Canada, the minus 40C rating is required as specied in the CE Code, Part I. Add 1000 V rating to the US type designations. Indicate that this option is only for use in the United States. Revise Table 2, type of stranding for aluminum to match what is specied

15、for copper. Revise Table 8 to address adding diameters for sizes 12-2 AWG and to the title to include single input wire. Expand Table 16, Thicknesses of insulation on 1000 V Types RW75, R90, and RW90 to include thickness requirements for the inner and outer layers of composite insulation and to perm

16、it the inner layer of composite insulation in RW75, RW90 and R90 to be other than silicone. Add new Table 19, Thickness of composite insulations on 1000 V Types RWU75 and RWU90. Add Annex F for requirements for rope-lay stranded exible conductors. Revise Annex K for editorial purposes in K.1, K.2.3,

17、 and K.3.1; to include extruded semi- conducting material in K.2.2; and to references back to test requirements. The new and revised requirements are substantially in accordance with Proposal(s) on this subject dated July 1, 2016, February 3, 2017, and August 25, 2017. JANUARY 9, 2018 UL 44 tr2UL CO
