ISO/CD 13385

Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.  Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. ISO shall not be held responsible for identifying a ny or all such patent rights. ISO 13385 was prepared by Technical Committee ISO/TC 213, Dimensional and geometrical product specification and verifikation . This first edition cancels and replaces ISO 3599:1976 and ISO 6906:1984 which have been technically revised.

5.3 Error of indication indication (MPE) The requirements on the error of indication apply to any indication based on the zero setting stated in 5.1. These requirements apply independently of the measuring range of the instrument. The error of indication must not be greater than the maximum permissible error given by the manufacturer. NOTE NOTE

As a result result,, the limi limits ts of perm permis issib sible le error error may may be greate greaterr than the the digita digitall step step or the vern vernier ier or the the scale scale inter interval val..

5.3.1 Small surface contact error (MPE 1) Error in the indicated value when the measurement is performed by using partial measuring surfaces at any position along the jaw and at any position of the measuring range. (see A.2.1)

5.3.2 Scale shift error (MPE 2) Error in the indicated value when using other measuring faces than the measuring faces for external measurement provided that a full contact of the measuring f aces is given. NOTE Scale shift includes e.g. error of straightness of the measuring faces for depth measuring and change of the direction of measuring force.

6 Calibration of metrological characteristics The methods shall evaluate the performance of the instrument within its measuring range. The global calibration of each scale point or each digital step over the measuring range will necessitate a large number of readings to be taken. When it is considered that the intended use of the instrument does not warrant global calibration, partial calibration or task related calibration should be taken into consideration. For the determination of the indication errors according to table 2 and table 3 a suitable number of intervals which are dependent on the scale interval or digital step, the total measuring range and the used measuring range are necessary. By these values calibration curves with a fixed zero can be recorded (see figure 5 in ISO 14978). It is possible to perform a modified global calibration by using a suitable sampling technique but this will result in an increase in the uncertainty of measurement.

Annex A (informative)

Error tests

A.1 Test methods The methods should evaluate the performance of the instrument throughout its measuring range. The methods described below do not purport to be the only valid test methods, but they are recommended to be used.  A calibration curve provides the simplest means of evaluating the performance of the instrument under test (see ISO 14978). Such a curve also provides useful certification evidence of calibration.

A.2 Error of Indication The error of indication may be tested with suitable instruments or material measure with an appropriate uncertainty for example with gauge blocks according to ISO 3650, step blocks or setting ring gauges.

A.2.1 Small surface surface contact error  The small surface contact error may be tested by measuring a material measure with small surfaces e.g. gage blocks, at different positions along the jaws at any position of the measuring rang (see figure A.1). NOTE NOTE

Parall Paralleli elism sm and and form form devia deviatio tion n of the the measur measuring ing surf surface ace of of the jaw jaws s as well well as scale scale erro errors rs are are includ included ed

Figure A.1 — Test arrangement for small surface contact error 

A.2.2 Scale shift error  The scale shift error may be tested by measuring a gauge block of e.g. 25mm with the measuring faces for external measuring and after that with a setting ring gauge of the same size with the measuring faces for internal measuring. For universal calliper with crossed knife edges this test method may be performed by using a gauge block and a setting ring gauge of 4mm.

NOTE NOTE 1

The diamete diameterr of the the setting setting ring gauge gauge for for testing testing universal universal callipe callipers rs shall shall not not below below 4mm. 4mm.

NOTE 2 The same test method may be used for testing the scale shift error between measuring faces for external measuring and the depth measuring rod.

A.2.3 Line contact contact error  The line contact error may be tested by measuring cylindrical material measure, e.g. cylindrical measuring pins, of a small diameter (approximately 10 mm) at different positions along the jaws, perpendicular to the plane of jaws (see figure A.2) NOTE NOTE

The test test of of the line line conta contact ct error error is is impor importan tantt to detec detectt worn worn measu measurin ring g surfac surfaces es for for used used calli calliper pers. s.

The non parallelism shall not be taken into account because it may be tested by small surface contact (see clause  A.2.1).

Annex B (informative)

Advice on application

The calliper does not adhere to the conditions prescribed in the Abbe Principle. There is a tilt in the slider caused by the clearance fit between slider and beam as well as by the pressure of the movable measuring face against the part to be measured. This results in angular deviations which influence the measuring value and the error of indication. To reduce this influence, the workpiece should contact the measuring surfaces of the calliper as close as possible to the beam. For this reason, the undercut of the jaw shall be as short as possible. Temperature and deformation factors have length-oriented influence. As a result, the smallest possible uncertainty of measurement is larger than the smallest fraction of a millimetre which is indicated. This has to be taken into consideration when evaluating the last fraction of a millimetre i n a measured result. In the case of digital indications, attention is to be paid to environmental factors, e.g. magnetic fields, electrical fields, dampness, etc. which could affect the functions of the electronic components of the instrument. The base of depth gauges extends to both the right and left sides of the beam. In either case of using one side or both sides of the base, set the base measuring face in close contact with the face of measur ing object, pressing the base squarely so that there will be no looseness of contact between the two during measurement.
