The following changes in requirements are being proposed:
1) For Preliminary Review Only: The proposed first edition of UL 1004-1, Rotating Electrical Machines - General Requirements, including the following changes: a) Addition of UL 840, the Standard for Insulation Coordination Including Clearances and Creepage Distances for Electrical Equipment as a means for evaluating the adequacy of spacings; b) Elimination of the Locked Rotor Cycling Test as an alternative to UL 1692, the Standard for Polymeric Materials - Coil Forms, as a means of evaluating the efficacy of Class A insulation systems; c) Revision of the method for evaluating nonmetallic functional motor parts used in rotating machines; d) Means to evaluate motors suitable for Field (as opposed to factory) installation; e) Clarification of the requirement for a normal temperature and ratings test for rotating machines; f) Updating of requirements for capacitors used in motors to reflect current capacitor technology; g) Documentation of the requirements for compatibility of oil used in rotating machinery as a cooling medium; h) Reduction in the potential required for dielectric testing of low-voltage rotating machinery; i) Glossary and term revisions
