DIN EN ISO 2286-2:2017-01

The total mass per unit area of a material, the mass per unit area of the substrate cloth and the mass per unit area of the coating are quantities which define the basic quality of a coated fabric and determine many of its physical properties. The substrate cloth mass determined by these methods does not necessarily represent the mass of the substrate cloth in the uncoated state. For example, in the case of coated fabrics in which a bonding agent has been used, the substrate cloth mass determined may be substantially higher than the uncoated mass because the prescribed treatment has not removed the entire coating. This will be particularly so in cases where the substrate cloth is made from multifilament or spun-fibre yarns. Dimensional changes in the substrate cloth during processing may also occur. This part of ISO 2286 specifies methods of determining the total mass per unit area, the mass per unit area of the coating and the mass per unit area of the substrate cloth of a rubber- or plastics-coated fabric. Methods for removing coatings of specific compositions are described in Annex A. The responsible German standardization committee for this standard is Working Committee NA 054-04-04 AA "Kunststoff-Folien und kunststoffbeschichtete Flächengebilde (Kunstleder); allgemeine Eigenschaften" ("Plastic films and plastics-coated fabrics (artificial leather); general characteristics") at DIN Standards Committee Plastics (FNK).
