CAN/CSA-ISO 16967:15 (R2020) ✓ Most Recent

Preface:

This is the first edition of CAN/CSA-ISO 16967, Solid biofuels — Determination of major elements — Al, Ca, Fe, Mg, P, K, Si, Na and Ti, which is an adoption without modification of the identically titled ISO (International Organization for Standardization) Standard 16967 (first edition, 2015-04-15).

For brevity, this Standard will be referred to as "CAN/CSA-ISO 16967" throughout.

This Standard is one of many Standards developed by ISO/TC 238 on Solid Biofuels that are being adopted by CSA Group.

The elements described as major elements of solid biofuels are in fact major elements of the fuel ashes more than of the fuels. The determination of these elements may be used to assess ash behaviour in a thermal conversion process or to assess utilization of ashes. Moreover, fuel contamination or process additives are indicated by high values of certain elements. Contamination of fuel with sand or soil is indicated by high values of several elements. In this Standard, wet chemical methods are described. Furthermore, this Standard describes methods for the determination of major elements of solid biofuels respectively of their ashes, which are Al, Ca, Fe, Mg, P, K, Si, Na, Ti. The determination of other elements such as barium (Ba) and manganese (Mn) is also possible with the methods described in this Standard.

This Standard includes two parts: Part A describes the direct determination on the fuel, this method is also applicable for sulfur and minor elements, Part B gives a method of determination on a prepared 550 °C ash.

Scope:

This International Standard describes methods for the determination of major elements of solid biofuels respectively of their ashes, which are Al, Ca, Fe, Mg, P, K, Si, Na, Ti. The determination of other elements such as barium (Ba) and manganese (Mn) is also possible with the methods described in this International Standard.
