14、atory equipment, was submitted to the IEC-CENELEC parallel vote and was approved by CENELEC as EN 61010-2-020 on 2006-07-01. This European Standard supersedes EN 61010-2-020:1994 + A1:1996. It has been updated to provide more specific wording for some of the instructions or subclauses, and the langu
15、age has been updated to reflect current terminology used in the industry today. This Part 2-020 is to be used in conjunction with EN 61010-1:2001, Safety requirements for electrical equipment for measurement, control and laboratory use Part 1: General requirements. Consideration may be given to futu
16、re editions of, or amendments to, EN 61010-1. This Part 2-020 supplements or modifies the corresponding clauses of EN 61010-1:2001 so as to convert it into the European Standard “Safety requirements for laboratory centrifuges“. Where a particular clause or subclause of Part 1 is not mentioned in thi
17、s Part 2-020, that clause or subclause applies as far as is reasonable. Where this part states “addition“, “modification“ or “replacement“, the relevant text of Part 1 is to be adapted accordingly.
