33、item or part of an item used for a test 4 Principle The linear dimensions of a test specimen are measured using an apparatus giving the required degree of accuracy. 5 Apparatus 5.1 Flat surface, larger than the largest dimensions of the test specimen. 5.2 Dial gauge, permitting reading to at least 0

34、05 mm. The measuring surface shall be of such a size that the total resultant measuring pressure is 1 kPa. The measuring pressure of the dial gauge can be reduced by removing the spring. The dial gauge, or any other electrical or optical measuring instrument having at least the same accuracy, can b

35、e fixed to a device to adapt the testing equipment to the size of the test specimen. 5.3 Micrometer, permitting readings to at least 0,05 mm. A micrometer shall only be used if it incorporates a device which indicates the onset of the force applied by the micrometer when it contacts the test specime

36、n surface. An example of such a device is an electrical circuit, consisting of a flexible wire, battery, lamp and an aluminium plate exerting a pressure of (50 1,5) Pa on the test specimen. An example of such an apparatus is given in Figure 1. 5.4 Sliding caliper, permitting readings to at least 0,1

37、 mm. The sliding caliper shall only be used if it does not cause any deformation of the test specimen. 5.5 Metal rule or metal tape, graduated in millimetres and permitting reading to at least 0,5 mm. Any test equipment which provides the same result with at least the same accuracy may be used. DIN

40、f measuring equipment shall be in accordance with the required accuracy of the measured value as given in the relevant test method standard or any other European Technical Specification. Where no such standard or specification exists, the required accuracy shall be agreed between parties, but it sha

41、ll correspond to the dimensions to be measured. DIN EN 12085:2013-06 EN 12085:2013 (E) 7 If the required accuracy of the dimension is expressed in millimetres, the choice of the equipment shall be as shown in Table 1.

44、e. Table 2 shall be used to provide the means for the selection of the equipment to be used where the accuracy is expressed in percentage terms. The choice depends on both the required accuracy and on the test specimen dimensions. Table 2 Choice of equipment related to required accuracy in percent R

47、o better than that of the metal tape or rule. 7.3 Number and location of measurements The number of the measuring locations shall depend on the size and the shape of the test specimen, but shall be at least two. The locations shall be as widely separated as possible, in order to give a good mean val

48、ue. If the median of three readings at each position is taken, the mean shall be calculated from the two or more median values. NOTE The median value at each position is taken because it is easier to keep in mind the majority of the measured values instead of noting all single values and calculating

49、 the mean value. 7.4 Measurement with dial gauge The measurement shall be made with the test specimen placed on a flat surface. DIN EN 12085:2013-06 EN 12085:2013 (E) 8 The measurements shall be made with and without the test specimen. The difference between the two measurements gives one reading. All readings shall be made to the nearest 0,05 mm. The mean value calculated shall be rounded to the nearest 0,1 mm. 7.5 Measurement with micrometer
