3、ional 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. Esch member body interested in a subject for which a technical committee has bee
4、n 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 (1 EC) on all matters of electrotechnical stan
5、dardization. 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. International Standard ISO 11093-5 was prepared by Technical

10、ANDARD o ISO ISO 11093=5:1994(E) Paper and board - Testing of cores - Part 5: Determination of characteristics of concentric rotation 1 Scope This part of ISO 11093 specifies a method for determining the characteristics of concentric rotation of cyclindrical board cores which meet the following crit
11、eria: - minimum wall thickness: 5mm - minimum extemal diameter: 60 mm - maximum Sample length: 3 200 mm 2 Normative references The following Standards contain provisions which, through reference in this text, constitute provisions of this part of ISO 11093. At the time of publication, the editions i
12、ndicated were valid. All Standards are subject to revision, and Parties to agreements based on this part of ISO 11093 are encouraged to investigate the possibility of applying the most recent editions of the Standards indicated below. Members of IEC and ISO maintain registers of currently valid Inte

ISO 11093-2:1994, Paper and board - Testing of cores - Part 2: Conditioning of test samples. 3 Principles 3.1 Determination of the roundness deviation (fR) by three-Point measurement Measurement between th
14、ree Points in a plane per- pendicular to the core axis where two Points are fixed in predetermined positions and the other moves in the direction of the measurement. 3.2 Determination of the straightness deviation (fs) by five-Point measurement Measurement between five Points in planes per- pendicul
15、ar to the core axis where four measuring Points are fixed in pairs in predetermined positions in two planes to the core axis and the other in a central plane perpendicular to the core axis moves in the direction of the measurement. 4 Apparatus The apparatus, shown in figure 1, consists of a rack (1)
16、 bearing two pairs of moveable supports (2). Esch pair consists of two free rotating support rollers (3) where the distance between the faces of the two tan be adjusted. The diameter of each roll shall be 85 mm * 1 mm and the face 20 mm ,t 1 mm. For example a 6209 roller bearing tan be used. Two mea
17、suring feelers are provided for carrying out the measuring. One (4) is placed above one of the pairs of supports and the other (5) is moveable between the pairs of supports on the rack. The measuring feelers are dial gauges graduated in 0,Ol mm and accurate to at least 0,015 mm, with a measuring ran
18、ge of 50 mm and a measuring strength of approximately 1,2 N. The scale shall have a minimum interval of 0,Ol mm. The feeler should be a flat surface with a diameter of 10 mm. 5 Preparation of test pieces 5.1 Sampling Sampling shall be carried out in accordance with ISO 11093-1. 5.2 Test pieces For c
19、ores less than 3 200 mm long, the complete undamaged core shall be tested. 1 Copyright International Organization for Standardization Provided by IHS under license with ISO Licensee=NASA Technical Standards 1/9972545001 Not for Resale, 04/26/2007 02:02:08 MDTNo reproduction or networking permitted w

21、 If there is an obvious differente in warpage of various positions of the long core, the Sample shall be taken from where the warpage is greatest. 5.3 Conditioning of test pieces The test pieces shall be conditioned in accordance with ISO 11093-2. 6 Measuring procedure Measuring shall be carried out
22、 in a Standard atmosphere identical to that used for the conditioning (see 5.3). The measuring feelers shall not produce any measurable deformation of the test piece during measuring. 6.1 Positioning of the support Adjust the distance between the two support rollers within both pairs so that tangent
23、s of support lines of the core form an angle of 120” t 5”. Adjust the distance between the inner faces of the support rollers of both pairs to the core length less (2OOmm*lO mm). This is the test length. Position the core centrally on the support rollers. 6.2 Measuring of roundness deviation Place t
24、he measuring feeler in contact with the core vertically above the imagined core axis and in the centre of a support roller pair within an accuracy of * 1 mm. Rotate the core through 360” and record the highest and lowest readings of the measuring feeler gauge to an accuracy of t 0,Ol mm. The differe
25、nte between the two readings is the individual value for the roundness deviation (fa), expressed in millimetres. 6.3 Measuring of straightness deviation Place the moveable measuring feeler in contact with the core vertically above the imagined core axis at a Point half-way between the two support ro
26、ller pairs. Rotate the core through 360 and record the highest and lowest readings of the measuring feeler gauge to an accuracy of * 0,Ol mm. Record the differente between the two readings. The straightness deviation if) Sr is half of the highest measured differente, determined to an accuracy of k 0
