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.
2 Normative reference
The following documents, in whole 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 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 42 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) 2 kPa土0,2 kPa;
b) 5 kPa+ 0,5 kPa.ISO 2286-3 pdf free download.
