ISO 1887-2014 pdf free.Textile glass – Determination of combustible-matter content. ISO 1887 specifies a method for the determination of the combustible-matter content of products made from textile glass, such as continuous-filament yarns, staple-fibre yarns, rovings, chopped strands, milled fibres, fabrics, chopped-strand and continuous-filament mats, and other glass reinforcements. 2 Terms and definitions For the purposes of this document, the following terms and definitions apply. 2.1 combustible-matter content ratio of the mass of material removed on calcination from a dried textile glass product to the mass of the dried product Note 1 to entry: This ratio is expressed as a percentage in this International Standard. It is equal to the content of size or finish on the textile glass product when the size or finish is completely combustible without significant residue (i.e. primarily organic products). 3 Principle Test specimens. dried under prescribed conditions, are weighed before and after calcination at a temperature of 625 °C ± 20 °C or, with types of glass which are unstable at this temperature, at a temperature between 500 °C and 600 °C, also kept constant to within 20 °C. 4 Apparatus 4.1 Air-circulation oven, for drying specimens, capable of being maintained at 105 °C ±…
