10、the UL adoptionof the corresponding IEC standard.In its IEC-based standards, UL uses the notations indicated below to identify national difference type, andthese types are additionally noted in this document. The standard may not use all types of thesedeviations.D1 - These are deviations which are b
11、ased on basic safety principles and requirements, elimination ofwhich would compromise safety for U.S. consumers and users of products.D2 - These are deviations based on safety practices. These are deviations for IEC requirements that maybe acceptable, but adopting the IEC requirements would require
12、 considerable retesting or redesign on themanufacturers part.DC - These are deviations based on the component standards and will not be deleted until a particularcomponent standard is harmonized with the IEC component standard.DE - These are deviations based on editorial comments or corrections.DR -
13、 These are deviations based on the national regulatory requirements.Each national difference contains a description of what the national difference entails. Typically one of thefollowing words is used to explain how the text of the national difference is to be applied to the base IECtext:Addition /
14、Add - An addition entails adding a complete new numbered clause, subclause, table, figure,or annex. Addition is not meant to include adding select words to the base IEC text.Deletion / Delete - A deletion entails complete deletion of an entire numbered clause, subclause, table,figure, or annex witho
15、ut any replacement text.Modification / Modify - A modification is an altering of the existing base IEC text such as the addition,replacement or deletion of certain words or the replacement of an entire clause, subclause, table, figure,or annex of the base IEC text.MAY 14, 2018 NATIONAL DIFFERENCES F

Clarified equipment ratedCAT II, III and IV is covered by this standard.3 Terms and Definitions Terms and definitions were a
19、dded or changed. KeyChanges include:Modified “Protective Conductor Terminal” replace by“Protective Earth Terminal”Added definition of Ambient as air surrounding theequipment.Removed Hand-held equipment.5.1.5.2 Terminals Functional Earth Terminal can be IEC 60417-5017 or IEC60417-5018.5.1.8 Field Wir

21、cted and added clarification. Items circled in red, onright side, may only apply to spread of fire considerations,clause 9. Identification of each circuit e.g. Mains circuit #1and #2 are added to clarify that those items apply todifferent (separated) circuits.6.7.1.2 Clearances Linear interpolation
22、is permitted between the nearest twopoints in Table 3.6.7.2.1 Clearance and Creepage Distances Annex FF added to clarify measurement of Clearance (CL)and Creepage (Cr) distances for components mounted ona printed wiring board (PWB). The key clarification was tonote that the required Cr distance from
23、 pad to pad may bebased on the component material group (Other insulatingmaterial) and not the PWB material group depending onthe distance between the component and the PWB. Thiscould increase the required Cr distances between thepads on the printed wiring board.6.7.101 Insulation for Field Wiring T
24、erminal of CAT II Table 104 was revised to align with IEC 61131-2.Requirements of some creepage and clearance distanceswere reduced. Clarified that Annex K shall be used forCAT III and IV applications.MAY 14, 2018NATIONAL DIFFERENCES FOR UL 61010-2-2014Table Continued on Next PageUL COPYRIGHTED MATE
