Solid biofuels - Determination of moisture content - Oven dry method - Part 1 : total moisture - Reference method

ISO 18134-1:2015 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]).

Solid biofuels - Determination of moisture content - Oven dry method - Part 1 : total moisture - Reference method

Le présent document décrit la méthode de détermination de la teneur en humidité totale d'un échantillon de biocombustibles solides par séchage à l'étuve. Cette méthode est utilisable lorsqu'une détermination avec une précision élevée est recherchée et peut être employée pour tous les combustibles solides. La teneur en humidité totale des biocombustibles n'est pas une valeur absolue et il est nécessaire de normaliser les conditions de sa détermination afin de permettre la réalisation de déterminations comparables.

Solid biofuels - Determination of moisture content - Part 1 : Reference method

<p>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).</p> <p>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.</p>

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
