ISO 2286-3-2016 pdf free.Rubber- or plastics-coated fabrics – Determination of roll characteristics – Part 3: Method for determination of thickness.
This part of Iso 2286 specifies a method for the determination, at a specified pressure, of the thickness of rubber- and plastics-coated fabrics, irrespective of the type of substrate employed. It is applicable to single-face, double-face and double-texture coated fabrics, as well as materials in which an expanded layer is included in the coating.

ISO 223 1:1989, Rubber- or plastics-coated fabrics — Standard atmospheres for conditioning and testing
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1 thickness
distance between the face and the back of a coated fabric, measured as the vertical distance between a reference plate on which the fabric rests and a parallel presser foot that is applying a pressure to the fabric
3.2 usable width
width of a coated fabric, excluding the selvedge, which is consistent in its properties, uniformly finished and free from unacceptable flaws
4 Apparatus
4.1 Dial gauge, of the deadweight type, designed to register the vertical distance between the bearing surfaces of a presser foot and reference plate, and equipped with a dial graduated to give a direct readout of the thickness to the nearest 0,01 mm. The gauge shall be calibrated in such a way as to permit at least one of the pressures specified in 4.2 to be obtained using at least one of the presser foot sizes.
4.2 Circular pressure foot, with a smooth, flat surface and a diameter of not less than 9 mm, capable of applying one or more of the following pressures:
a) 2kPa±0,2kPa;
b) 5kPa±0,5kPa;
c) lOkPa±1.OkPa;
d) 24 kPa ± 2,4 kPa.
NOTE 1 In case of the pressure loot of 10 mm diameter, the force is calculated from the pressure for each.
a) 0,157N±0,016N
b) 0,393 N ± 0,039 N
c) 0,785 N ± 0,079 N
d) l,88N±0,19N
NOTE 2 The actual pressure exerted by the presser foot can be calculated in one of the following ways:
a) by determining
1) the force exerted by the presser foot assembly, using a calibrated counterbalance, and
2) the surface area of the presser foot by direct measurement. or
b) by using a tension dial gauge.
4.3 Reference plate (anvil), having a plane upper surface of diameter not less than, preferably 50 mm greater than that of the presser foot (4.2).
4.4 Means for moving the pressure foot, in a direction normal to the upper surface of the reference plate so that its bearing surface is maintained parallel to the upper surface of the reference plate.ISO 2286-3 pdf download.
