This document describes the method of determining the moisture content of a test sample of solid biofuels by drying in an oven and can be used when high precision of the determination of moisture content is necessary. The method described in this document 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 Biomass materials can contain small amounts of volatile organic compounds (VOC) which can evaporate when determining moisture content by oven drying (see References [1] and [2]). The release of such compounds is quite small relative to the overall moisture content as determined by this method and is disregarded in this document.
Abstract
Overview
EN ISO 18134-1:2022 - "Solid biofuels - Determination of moisture content - Part 1: Reference method" - is the CEN-adopted reference for measuring moisture in solid biofuels by oven drying. Intended where high-precision moisture determination is required, the method applies to all solid biofuels and requires results to be reported on a wet basis (moisture as received, relative to total sample mass). The procedure is internationally harmonized (ISO 18134-1:2022) and supersedes the 2015 edition.
Key Topics and Requirements
- Principle: Dry a test portion in an air atmosphere oven at (105 ± 2) °C until constant mass is reached; calculate moisture from mass loss.
- Apparatus: temperature-controlled drying oven (air changes 3–5/h), non-corrodible trays, and a balance readable to 0.1 g.
- Sample preparation:
