NOTENormative references to International Standards are listed in annex ZA (normative).EN ISO 5084:1996 BSI 10-1998 3 1 Scope This International Standard specifies a method for the determination of the thickness

22、of textiles and textile products when under a specified pressure. It is not applicable to textile floor coverings, nonwovens, geotextiles and coated fabrics for which specific International Standards exist (seeannex B). 2 Normative references The following standards contain provisions which, through

23、 reference in this text, constitute provisions of this International Standard. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this International Standard are encouraged to investigate the possibility of applyin

24、g the most recent editions of the standards indicated below. Members of IEC and ISO maintain registers of currently valid International Standards.

25、: Metrological confirmation system for measuring equipment. 3 Definition For the purposes of this International Standard, the following definition applies. 3.1 thickness of a textile perpendicular distance between two reference plates exerting a pressure of 1 kPa or less on the textile 4 Principle T

26、he thickness of a specimen is measured as the distance between the reference plate on which the specimen rests and a parallel circular presser-foot that exerts a specified pressure on the area of the textile under test. A test specimen is placed between two reference plates which exert a known press

27、ure on the specimen. The perpendicular distance between the reference plates is measured and recorded after a specified time. 5 Apparatus 5.1 Thickness tester The confirmation system for the thickness tester shall comply with ISO 10012-1. The thickness tester shall incorporate (or be equipped with)

28、the following elements. 5.1.1 Interchangeable presser-feet, of area appropriate to the type of fabric to be tested. The recommended pressure-foot area for the test is(2 000 20) mm 2 , corresponding to a circular presser-foot of diameter (50,5 0,2) mm (seealsoannex A). If other test areas have to be

29、used, this shall be agreed by the interested parties and shall be stated in the test report. 5.1.2 Reference plate, with a plane upper surface of diameter at least 50mm greater than that of the presser-foot(5.1.1). 5.1.3 Means for moving the presser-foot (in a direction normal to the upper surface o

30、f the reference plate), so that its bearing surface is maintained horizontal and parallel to the upper surface of the reference plate (5.1.2) and so that pressures of (1 0,01) kPa and (0,1 0,001) kPa can be applied to a test specimen supported on the plate (see annex A). 5.1.4 Thickness gauge, capab

31、le of registering the distance between the bearing surface of the presser-foot (5.1.1) and the reference plate (5.1.2) to an accuracy of 0,01 mm. 5.2 Stopwatch 6 Atmosphere for conditioning and testing The textile samples shall be conditioned and the test conducted in the standard atmosphere for con

32、ditioning and testing of textiles specified inISO139. 7 Sampling, selection and conditioning of specimens 7.1 Take samples in one of the following ways, as appropriate: a) in accordance with the directions given in the relevant material specification; b) if such directions are not included in the ma

33、terial specification, in accordance with the procedure agreed upon by the parties interested in the test results. 7.2 Select test areas for samples in accordance with clause A.3. For fabrics which are sensitive to deformation, e.g. certain knitted fabrics, cut test specimens in accordance with claus

34、e A.3. If wide-width fabrics cannot be handled without distortion, cut test specimens. 7.3 Condition the samples or test specimens in the relaxed state until equilibrium is reached with the standard atmosphere for testing. NOTE 1It is recommended to condition the samples at least for16 h in the rela

35、xed state.EN ISO 5084:1996 4 BSI 10-1998 8 Procedure 8.1 Clean the presser-foot (5.1.1) and the reference plate (5.1.2). Check that the presser-foot shaft moves freely. Load the presser-foot to exert the appropriate specified pressure on the reference plate, and set the thickness gauge (5.1.4) to re

36、ad zero. An applied pressure of (1 0,01) kPa is recommended. 8.2 Raise the presser-foot and position the sample or test specimen, without tension and distortion, on the reference plate so that no part of the area to be measured is closer than 150 mm to the selvedge. Ensure that the area chosen for t

37、he test is free from creases. 8.3 Lower the presser-foot gently onto the specimen and note the gauge reading after (30 5) s. 8.4 Determine, in accordance with the procedure in8.2 and 8.3, the thickness of at least five different areas on the sample or at least five test specimens (see annex A). 9 Ex

38、pression of results Calculate the arithmetic mean of the measurements determined in accordance with clause 8 to an accuracy of 0,01mm. Calculate the coefficient of variation to the nearest 0,1 % and the 95 % confidence limits to the nearest 0,01 mm. 10 Test report The test report shall include at le

39、ast the following information: a) statement that the test was conducted in accordance with this International Standard, and date of test; b) description of the fabric; width of narrow fabrics, if relevant; c) area of the presser-foot used; d) applied pressure; e) number of tests; f) thickness of the

40、 textile or textile product, presented as the arithmetic mean, expressed in millimetres and, if required, the coefficient of variation expressed as a percentage and the 95 % confidence limits, expressed in millimetres (seeclause9); g) any deviation, by agreement or otherwise, from the procedure spec

41、ified, and the reasons for this.EN ISO 5084:1996 BSI 10-1998 5 Annex A (normative) Test area position and alternatives for presser-foot area and applied pressure A.1 Presser-foot If the test area of the presser-foot recommended in5.1.1 is not used, then use one of the following: for narrow fabrics,

42、e.g. usable width less than50 mm, test area (100 1) mm 2corresponding to a circular presser-foot of diameter (11,28 0,05) mm; for other fabrics, test area (10 000 100) mm 2corresponding to a circular presser-foot of diameter (112,84 0,5) mm. A.2 Applied pressure If the pressure recommended in 8.1 is

43、 not used, then use (0,1 0,001) kPa, e.g. for raised, pile or loop fabrics and certain knitted fabrics.
