20、f ISO 11093 specifies a method for determining the characteristics of concentric rotation of cylindrical board cores which meet the following criteria: minimum wall thickness: 5 mm; minimum external diameter: 60 mm; maximum sample length: 3 200 mm.2 Normative referencesThe following documents, in wh
21、ole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.ISO 110931, Paper and board Testing of
22、 cores Part 1: SamplingISO 110932, Paper and board Testing of cores Part 2: Conditioning of test samples3 Principles3.1 Determination of roundness deviation (fR) by three-point measurementMeasurement between three points in a plane perpendicular to the core axis where two points are fixed in predete
23、rmined positions and the third moves in the direction of the measurement.3.2 Determination of the straightness deviation (fS) by five-point measurementMeasurement between five points in planes perpendicular to the core axis where four measuring points are fixed in pairs in predetermined positions in
24、 two planes perpendicular to the core axis, and the fifth in a central plane perpendicular to the core axis moves in the direction of the measurement.4 ApparatusThe apparatus, shown in Figure 1, consists of two supports (2), a rack (1), and two measuring heads (4 and 5). Each support consists of two
25、 free rotating support rollers mounted side by side (3) where the distance between the two can be adjusted. The diameter of each roller shall be (85 1) mm and the width shall be (19 1) mm. For example, a 6209 roller bearing can be used.Each measuring head consists of a flat foot with a diameter of 1
26、0 mm, a rod which transmits the vertical movement of the foot to a dial gauge and a dial gauge graduated in 0,01 mm, accurate to at least 0,005 mm. The load exerted by each measuring foot on the test piece is approximately 1,2 N. One of the measuring heads (4) is fixed directly above the mid-point b
27、etween one pair of support rollers. The other measuring head (5) is moveable parallel to the rack.Paper and board Testing of cores Part 5: Determination of characteristics of concentric rotation DIN ISO 11093-5:2017-05 5 123456Key1 rack2 supports3 support rollers4 measuring head5 measuring head, mov

29、est piece from 1 200 mm to 3 200 mm long shall be cut. If there is an obvious difference in warpage between various positions of the long core, the test piece shall be taken from where the warpage is greatest.5.3 Conditioning of test piecesThe test pieces shall be conditioned in accordance with ISO
30、11093-2.DIN ISO 11093-5:2017-05 6 6 Measuring procedure6.1 GeneralMeasuring shall be carried out in a standard atmosphere identical to that used for the conditioning (see 5.3). The measuring heads shall not produce any measurable deformation of the test piece during measuring.6.2 Positioning of the
31、supportAdjust the distance between the two support rollers within each pair so that the tangents to the lines of the support of the core form an angle of 120 5. Adjust the distance between the inner faces of the two pairs of support rollers to the core length less (200 10) mm. This is the test lengt
32、h. Position the core centrally on the support rollers.6.3 Measuring of roundness deviationPlace the foot of the fixed measuring head in contact with the core so that it is centrally located with respect to the core axis and the line between the support-roller pair to an accuracy of 1 mm. Rotate the
33、core through 360 and record the highest and lowest readings of the gauge to an accuracy of 0,01 mm. The difference between the two readings is the individual value for the roundness deviation ( fR), expressed in millimetres.6.4 Measuring of straightness deviation6.4.1 Straightness deviationPlace the
34、 foot of the moveable measuring head in contact with the core so that it is centrally located with respect to the core axis at a point half-way between the two support-roller pairs. The measuring head placed at the half-way point is located with an accuracy of 1 mm. Rotate the core through 360 and r
35、ecord the highest and lowest readings of the gauge to an accuracy of 0,01 mm. Record the difference between the two readings. The straightness deviation ( fS) is half of this measured difference (x), determined with an accuracy of 0,01 mm, as given in Formula (1):fxS=2(1)wherefSis the straightness d
