CENELEC members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard the status of a national standard without any alteration. Up-to-date lists and bibliog

10、raphical references concerning such national standards may be obtained on application to the Central Secretariat or to any CENELEC member. This European Standard exists in three official versions (English, French, German). A version in any other language made by translation under the responsibility

11、of a CENELEC member into its own language and notified to the Central Secretariat has the same status as the official versions.

13、asuring, control, and laboratory 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 o

14、r subclauses, and the language 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. Conside

15、ration may be given to future 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 Par

16、t 1 is not mentioned in this 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. The following dates were fixed: latest date by which the EN has to be imple

17、mented at national level by publication of an identical national standard or by endorsement (dop) 2007-04-01 latest date by which the national standards conflicting with the EN have to be withdrawn (dow) 2009-07-01 In this standard: 1) the following print types are used: requirements: in roman type;

18、 NOTES: in small roman type; conformity and tests: italic type; terms used throughout this standard which have been defined in Clause 3: SMALL ROMAN CAPITALS; 2) subclauses, figures, tables and notes which are additional to those in Part 1 are numbered starting from 101; additional annexes are lette
