The information in Sub-clauses 2.1, 2.2 and 2.3, although not necessarily applicable to all the summaries, is of gene

5、ral application. 2.1 Guidance Many of the standards in Publication 68-2 contain guidance on the application of the testing procedure and much of this is of particular value to specification writers and others who are not required to have a knowledge of the detailed provisions of a Test. In the case

6、of these standards, the summaries will make no specific reference to guidance. STD-BSI BS EN bUb-4-ENGL 177b m Lb24bb7 0582b4 999 Page 4 EN 60068-4 : 1996 There are other cases, for example solar radiation testing (Publica- tion 68-2-51, where guidance is to be found in another standard in the Publi

7、cation 68-2 series (Publication 68-2-9 in the case of the example), or - and then described as background information - in a standard in the Publication 68-3 series. In these cases, reference is made in the summary to the other standards concerned irrespective of their degree of relevance for specif

8、ication writers in order that they can indicate fully in their specifications the sources of detailed information which laboratories will require. The standard will then be listed in Clause 5. 2.2 Storage Guidance on the application of Tests in the Publication 68-2 series to simulate the effects of

9、storage, from short-term to long-term, is given in Publication 68-2-48, to which reference should be made in appro- priate cases. 2.3 Mounting The mounting requirements for specimens to be subjected to certain of the vibration and shock tests covered by the summaries, .namely shock and bump (Test Ea

10、, Publication 68-2-27; Test Eb, Publica- tion 68-2-29), sinusoidal and random vibration (Test Fc, Publication 68-2-6; Test Fd, Publications 68-2-34, 68-2-35, 68-2-36 and 68-2-37) and steady-state acceleration (Test Ga, Publication 68-2-7), are the subject of Publication 68-2-47, to which attention s

11、hould be drawn in relevant specifications. This applies also, of course, when dealing with combined or composite tests, as defined in Clause 3, embodying one or more of the tests mentioned. 3. Definitions The following list of generally-applicable definitions is based, with some editing, on those gi

12、ven in Publication 68-1. For other definitions, refer to Publications 68-1 and 68-2. 3.1 Test Complete series of operations implied by its title, normally comprising the following operations, when required: a 1 b) initial examination and measurements; c) conditioning; d) recovery; e) final examinati

13、on and measurements. Note.- Intermediate measurements may be required during conditioning p re- con d i t ion i n g ; and/or recovery. STD.BS1 BS EN bb8-q-ENGL 277b ZbZLibb 0582b75 825 Page 6 EN 60068-4 : 1996 3.1.1 Pre-conditioning Treatment of a specimen with the object of removing or partly count

14、eracting the effects of its previous history. 3.1.2 Conditioning Exposure of a specimen to environmental conditions in order to determine the effect of such conditions on the specimen. 3.1.3 Recovery Treatment of a specimen, after environmental conditioning, in order that the properties of the speci

15、men may be stabilized before measurement. 3.2 Specimen Product designated to be tested in accordance with the procedures of IEC 68. Note. - The term “specimen“ includes any auxiliary parts or systems that are integral functional features of the specimen, for example systems for cooling and heating.

16、3.2.1 Heat-dissipating specimen Specimen with the hottest point on its surface, measured in free air conditions and under the air pressure specified in Sub-clause 5.3.1 of IEC 68-1, more than 5 OC above the ambient temperature of the surrounding atmosphere after tem- perature stability has been reac

17、hed. 3.2.2 Non-heat dissipating specimen 3 -3 3.4 3.5 3.6 Specimen other than as defined in Sub-clause 3.2.1. Relevant specification Set of requirements to be satisfied by a product, indicating the procedure(s) necessary to determine whether the requirements given are satisfied. Severity Set of para

18、meters for the conditioning of the specimen. Combined test simultaneously. Composite test Test in which two or more test environments act up n the specimen Test in which the specimen is exposed to two or more test environments in close succession.
