CAN/CSA-ISO 19743:21 PDF

CSA Preface 

This is the first edition of CSA ISO 19743, Solid biofuels - Determination of content of heavy extraneous materials larger than 3,15 mm , which is an adoption without modification of the identically titled ISO (International Organization for Standardization) Standard 19743 (first edition, 2017-04). This Standard specifies a method for the determination of content of heavy extraneous materials larger than 3,15 mm by the use of sink-and-float separation combined with elutriation. This Standard is applicable to woody biomass in accordance with CSA ISO 17225-2:15, Solid biofuels - Fuel specifications and classes - Part 1: General requirements. This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group. 

Scope 

This document specifies a method for the determination of content of heavy extraneous materials larger than 3,15 mm by the use of sink-and-float separation combined with elutriation. This document is applicable to woody biomass in accordance with ISO 17225-1:2014, Table 1. 

NOTE 1 This method is designed to determine the level of impurities larger than 3,15 mm top size with a specific density >1 g/cm3 such as stones, glass, rubber, metal and certain types of plastics. 

NOTE 2 During the processing of the sample, hand sorting of light impurities with a specific density less than or equal to 1 g/cm3 (e.g. plastic foil) can also be done.
