CSA ISO 18134-1:15 (R2020)

CSA Preface This is the first edition of CAN/CSA-ISO 18134-1, Solid biofuels — Determination of moisture content — Oven dry method — Part 1: Total moisture — Reference method , which is an adoption without modification of the identically titled ISO (International Organization for Standardization) Standard 18134-1 (first edition, 2015-09-01). This Standard is one of three Standards developed by ISO/TC 238 on Solid Biofuels that are being adopted by CSA Group under the series Determination of moisture content – Oven dry method, which consists of the following: a) ISO 18134-1, Part 1: Total moisture – Reference method; b) ISO 18134-2, Part 2: Total moisture – Simplified method; and c) ISO 18134-3, Part 3: Moisture in general analysis sample. This Standard describes the method of determining the total moisture content of a test sample of solid biofuels by drying in an oven and should be used when high precision of the determination of moisture content is necessary. The method described in this Standard is applicable to all solid biofuels. The moisture content of solid biofuels (as received) is always reported based on the total mass of the test sample (wet basis). This Standard was reviewed for Canadian adoption by the CSA Technical Committee on Solid Biofuels, under the jurisdiction of the CSA Strategic Steering Committee on Fuel Burning Equipment, and has been formally approved by the Technical Committee. 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 part of ISO 18134 describes the method of determining the total moisture content of a test sample of solid biofuels by drying in an oven and may be used when high precision of the determination of moisture content is necessary. The method described in this International Standard is applicable to all solid biofuels. The moisture content of solid biofuels (as received) is always reported based on the total mass of the test sample (wet basis). NOTE The term moisture content, when used with biomass materials, can be misleading since untreated biomass frequently contains varying amounts of volatile compounds (extractives) which might evaporate when determining moisture content by oven drying (see References [2] and [3]).
