40、quipment4.1 GeneralThe choice of measuring equipment for the measurement of dimensions is influenced by the characteristics of the specimen being measured and by the requirements on the accuracy.NOTE Each material will differ in its response to test method parameters, which include, but cannot be li
41、mited to the rate of loading, the ultimate load, the dwell time and the dimensions of the contact points between the measuring instrument and the test specimen (presser foot and anvil, or other geometries). For a specific plastics material, these responses can cause measurements made using one metho
42、d to differ significantly from measurements made using another method. The compressibility of the material will have greater influence when comparing measurements taken with non-contact apparatus and spring-loaded micrometers.Care shall be taken to ensure that the measuring equipment used does not l
43、eave on the measured surface any marks, scratches or cracks which could influence the results of the measurement.International Standards for measuring equipment do not specify limits on errors but demand that the manufacturers data sheet supply all the necessary information. The requirements on inst
44、rument capabilities given in this International Standards enable the user to select the appropriate instrument.4.2 MicrometersMicrometers shall conform to the requirements of ISO 3611 where appropriate.Micrometers that are equipped with a system which ensures that a preset load is applied during mea
45、surement shall exert a force at the measurement faces of between 5 N and 15 N.4.3 Vernier callipersVernier callipers shall conform to the requirements of ISO 13385-1. Digital-reading callipers can be used provided they comply with the relevant requirements of these standards.4.4 Dead-weight dial gau
46、ge micrometers and electronic digital indicator gauges4.4.1 Dead-weight dial gauge micrometers shall conform to the requirements of ISO 463 or, if applicable, ISO 9493. For electronic digital indicator gauges ISO 13102 applies. Micrometers and electronic indicator gauges shall have the following fea
47、tures (if applicable):a) a presser foot that moves in an axis perpendicular to the anvil face;b) presser foot and anvil surfaces (those which contact the specimen) that are parallel to within 5 m;c) a vertical dial spindle;d) a dial indicator that is essentially friction-free and capable of repeatab
48、le readings within 10 m at zero setting or on a steel gauge block;DIN EN ISO 16012:2016-02 EN ISO 16012:2015 (E) 6 e) a frame, housing the indicator, of such rigidity that a load of 15 N applied to the dial housing will produce a deflection of the frame not greater than the smallest scale division on the indicator dial.The dial shall be graduated continuously to read directly to the nearest 2,5 m or
