23、ection 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 two planes perpendicular to the core axis, and
24、 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 free rotating support rollers mounted side by
25、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 10 mm, a rod which transmits the vertical moveme
26、nt 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 between one pair of support rollers. The other m
27、easuring head (5) is moveable parallel to the rack.

28、mplingSampling shall be carried out in accordance with ISO 11093-1.5.2 Test piecesFor cores less than 3 200 mm long, the complete undamaged core shall be tested.For cores more than 3 200 mm long, a test piece from 1 200 mm to 3 200 mm long shall be cut. If there is an obvious difference in warpage b
29、etween 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 11093-2.2 ISO 2016 All rights reservedBS ISO 11093-5:2016ISO 11093-5:2016(E)6 Measuring procedure6.1
30、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 supportAdjust the distance between the two support rollers
31、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 length. Position the core centrally on the support rollers.6.3 M
32、easuring 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 core through 360 and record the highest and lowest readings
33、 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 foot of the moveable measuring head in contact with the co
34、re 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 record the highest and lowest readings of the gauge to an ac
35、curacy 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 deviation, in mm;x is the measured difference, in mm.6.4.2 P
36、recision of the measurement systemProvided that the rack has the stiffness needed, the precision of the measurement system is sufficient for cores which have a straightness deviation 0,3 mm/m.
