National Differences For UL 61010-1 Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use - Part 1: General Requirements
|Publication Date:||12 July 2004|
This document provides a single listing of the technical National Differences included in the UL adoption of the corresponding IEC standard. Editorial national differences (those marked DE) are not included in this technical compilation.
In its IEC-based standards, UL uses the notations indicated below to identify national difference type, and these types are additionally noted in this document. The standard may not use all types of these deviations.
DR - These are deviations based on the National Electrical Code (NEC) and other U.S. Regulatory Requirements.
D1 - These are deviations which are based on basic safety principles and requirements, elimination of which 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 may be acceptable, but adopting the IEC requirements would require considerable retesting or redesign on the manufacturer's part.
DC - These are deviations based on the component standards and will not be deleted until a particular component standard is harmonized with the IEC component standard.
DE - These are deviations based on editorial comments or corrections
