CSA Group Solid biofuels - Determination of total content of sulfur and chlorine (Adopted ISO 16994:2015, first edition, 2015-04-01)

Preface This is the first edition of CAN/CSA-ISO 16994, Solid biofuels - Determination of total content of sulfur and chlorine, which is an adoption without modification of the identically titled ISO (International Organization for Standardization) Standard 16994 (first edition, 2015-04-01). For brevity, this Standard will be referred to as "CAN/CSA-ISO 16994" throughout.  This Standard is one of many Standards developed by ISO/TC 238 on Solid Biofuels that are being adopted by CSA Group. Sulfur and chlorine are present in solid biofuels in varying concentrations. During the combustion process, they are usually converted to sulfur-oxides and chlorides. The presence of these elements and their reaction products can contribute significantly to corrosion and to environmentally harmful emissions.  This Standard describes methods for the determination of the total sulfur and total chlorine content in solid biofuels. This Standard specifies two methods for digestion of the fuel and different analytical techniques for the quantification of the elements in the digest solutions. The use of automatic equipment is also included in this Standard, provided that a validation is carried out as specified and that the performance characteristics are similar to those of the method described in this Standard.    Scope This International Standard describes methods for the determination of the total sulfur and total chlorine content in solid biofuels. This International Standard specifies two methods for decomposition of the fuel and different analytical techniques for the quantification of the elements in the decomposition solutions. The use of automatic equipment is also included in this International Standard, provided that a validation is carried out as specified and that the performance characteristics are similar to those of the method described in this International Standard.
