9、r products”, Subcommittee SC 2 “Testing and analysis” (Secretariat: JISC, Japan). The responsible German body involved in its preparation was the Normenausschuss Materialprfung (Materials Testing Standards Committee), Working Committee NA 062-04-34 AA Prfung der physikalischen Eigenschaften von Kaut
10、schuk und Elastomeren. The following should be taken into consideration: Re Subclause 5.2: Since the surface of foam rubber test pieces is damaged after splitting or cutting, testing should be carried out on pieces having the original thickness. Re Subclause 7.1: A digital dial gauge having a resolu
11、tion of 0,001 mm should be used for this method. Thus the gauge will certainly be capable of measuring thickness with the required accuracy. The requirement that the foot is not to extend over the edge of the test piece need not be met if it is possible to adjust the specified measuring pressure to
12、the dimensions of the test piece. The test piece should lay flat on the baseplate throughout the entire measuring procedure. Re Subclause 7.2: A digital calliper having a resolution of 0,01 mm should be used. The error of measurement should be no greater than 0,1 %. Re Subclause 7.3: The error of me
13、asurement should be no greater than 0,5 % or 1 mm, whichever is the smaller. The DIN Standards corresponding to the International Standards referred to in this document are as follows: ISO 525 DIN ISO 525 ISO 3302-1 DIN ISO 3302-1 Attention is drawn to the possibility that some of the elements of th
14、is document may be the subject of patent rights. DIN shall not be held responsible for identifying any or all such patent rights. Amendments This standard differs from DIN ISO 23529:2007-01 as follows: a) a warning note relating to the safe handling of hazardous substances or waste has been included
15、; b) the standard has been editorially revised. Previous editions DIN 53502: 1956-04, 1959-11, 1972-08 DIN 53500: 1979-03, 1989-09 DIN 53534: 1984-02, 1994-05, 2000-04 DIN ISO 471: 1998-02 DIN ISO 4666-1: 1992-01, 1995-08 DIN ISO 23529: 2007-01 3 DIN ISO 23539:2012-10 National Annex NA (informative)

17、ernational Standard should be familiar with normal laboratory practice. This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user to establish appropriate safety and health practices and to ensure compliance with any n
18、ational regulatory conditions. CAUTION Certain procedures specified in this International Standard can involve the use or generation of substances, or the generation of waste, that could constitute a local environmental hazard. Reference should be made to appropriate documentation on safe handling a
19、nd disposal after use. 1 Scope This International Standard specifies general procedures for the preparation, measurement, marking, storage, and conditioning of rubber test pieces for use in physical tests specified in other International Standards, and the preferred conditions to be used during the
20、tests. Special conditions, applicable to a particular test or material or simulating a particular climatic environment, are not included, nor are special requirements for testing whole products. This International Standard also specifies the requirements for the time interval to be observed between
21、forming and testing of rubber test pieces and products. Such requirements are necessary to obtain reproducible test results and to minimize disagreements between customer and supplier. 2 Identification and record keeping Records shall be kept of the identity of each test piece so that it is identifi
22、able with the sample supplied and such that all the relevant details of preparation, storage, conditioning and measurement are traceable to each individual test piece. Each sample or test piece shall be individually identifiable by marking or segregation at each stage of its preparation and testing.
23、 Where marking is used as the method of identification, the markings shall be sufficiently durable to ensure that the test piece or sample remains identifiable until discarded. Where grain effects can be significant, the direction of the grain shall be identified on each sample or test piece. The me
24、thod of marking shall not affect the properties of the sample or test piece and shall avoid significant surfaces, i.e. surfaces which are to be directly tested (e.g. in abrasion tests) or surfaces at which fracture terminates the test (e.g. tear or tensile tests). 5 DIN ISO 23539:2012-10 3 Standard
