CSA Preface

This is the first edition of CAN/CSA-ISO 18134-3, Solid biofuels — Determination of moisture content — Oven dry method — Part 3: Moisture in general analysis sample, which is an adoption without modification of the identically titled ISO (International Organization for Standardization) Standard 18134-3 (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 moisture in the analysis test sample by drying in an oven. It is intended to be used for general analysis samples in accordance with EN 14780. 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 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 moisture in the analysis test sample by drying in an oven. It is intended to be used for general analysis samples in accordance with EN 14780. The method described in this part of ISO 18134 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).

Since biofuels in small particle size are very hygroscopic, their moisture content will change with humidity in the atmosphere and therefore, the moisture of the test portion is determined simultaneously with determination of for example calorific value, carbon content, and nitrogen content.

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 can evaporate when determining the moisture content by oven drying (see References [1] and [2]).
