CSA ISO 18134-2:21

CSA Preface This is the second edition of CSA ISO 18134-2, Solid biofuels — Determination of moisture content — Oven dry method — Part 2: Total moisture — Simplified method , which is an adoption without modification of the identically titled ISO (International Organization for Standardization) Standard 18134-2 (second edition, 2017-01). It supersedes the previous edition, published in 2015 as CAN/CSA-ISO 18134-2 (adopted ISO 18134-2:2015). 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 second edition constitutes a minor revision with the following changes: — the source has been deleted in Clauses 3.2 and 3.3; — a few subclauses have been rephrased; — the last sentence of Clause 7.2 has been deleted; and — in Clause 10, the last two items have been renumbered e) and f). This Standard describes the method of determining the total moisture content of a test sample of solid biofuels by drying in an oven and is used when the highest precision is not needed, e.g., for routine production control on site. The method described in CSA ISO 18134 (all parts) 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 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 describes the method of determining the total moisture content of a test sample of solid biofuels by drying in an oven and is used when the highest precision is not needed, e.g. for routine production control on site. The method described in ISO 18134 (all parts) 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 [1] and [3]).
