CSA ISO 17827-1:17 (R2021)

CSA Preface This is the first edition of CAN/CSA-ISO 17827-1, Solid biofuels — Determination of particle size distribution for uncompressed fuels — Part 1: Oscillating screen method using sieves with apertures of 3,15 mm and above, which is an adoption without modification of the identically titled ISO (International Organization for Standardization) Standard 17827-1 (first edition, 2016-03-01). For brevity, this Standard will be referred to as "CAN/CSA-ISO 17827-1" throughout. This Standard is one of two StandardDetails developed by ISO/TC 238 on Solid Biofuels that are being adopted by CSA Group under the series Determination of particle size distribution for uncompressed fuels, which consists of the following: a) ISO 17827-1, Part 1: Oscillating screen method using sieves with apertures of 3,15 mm and above; and b) ISO 17827-2, Part 2: Vibrating screen method using sieves with aperture of 3,15 mm and below. This Standard specifies a method for the determination of the size distribution of particulate biofuels by the horizontally oscillating screen method. It applies to particulate uncompressed fuels with a nominal top size of 3,15 mm and above, e.g., wood chips, hog fuel, olive stones, etc. The method is intended to characterize material up to a particle size class of P63. For larger P-classes, the characterization is mainly done by hand sorting. This Standard has been developed in compliance with StandardDetails Council of Canada requirements for National StandardDetails of Canada. It has been published as a National Standard of Canada by CSA Group. Scope This part of ISO 17827 specifies a method for the determination of the size distribution of particulate biofuels by the horizontally oscillating screen method.
