Solid biofuels - Determination of self-heating of pelletized biofuels - Part 1: Isothermal calorimetry (ISO 20049-1:2020)

This document:
a)   specifies a general test procedure for quantification of the spontaneous heat generation from solid biofuel pellets using isothermal calorimetry;
b)   specifies a screening test procedure for wood pellets using an instrument temperature of 60 °C;
c)   establishes procedures for sampling and sample handling of solid biofuel pellets prior to the analysis of spontaneous heat generation; and
d)   gives guidance on the applicability and use of isothermal calorimetry for calculation of the net reaction rate of the heat producing reactions of solid biofuel pellets.
The test procedure given in this document quantifies the thermal power (heat flow) of the sample during the test, it does not identify the source of self-heating in the test portion analysed.
Data on spontaneous heat generation determined using this document is only associated with the specific quality and age of the sample material. The results are product specific.
This document is applicable to solid biofuel pellets only.
The information derived using this document is for use in quality control and in hazard and risk assessments related to the procedures given in ISO 20024:2020.

b)    spécifie un mode opératoire d'essai de présélection pour les granulés de bois utilisant une température d'appareil de 60 °C;
c)    établit des procédures d'échantillonnage et de manipulation des échantillons de granulés de biocombustibles solides avant l'analyse de la production spontanée de chaleur; et
d)    fournit des recommandations relatives à l'applicabilité et à l'utilisation de la détermination calorimétrique isotherme pour le calcul de la vitesse de réaction nette des réactions productrices de chaleur des granulés de biocombustibles solides.
Le mode opératoire d'essai fourni dans le présent document quantifie la puissance thermique (flux thermique) de l'échantillon pendant l'essai; il n'identifie pas la source de l'auto-échauffement dans la prise d'essai analysée.
Les données relatives à la production spontanée de chaleur déterminées à l'aide du présent document sont uniquement associées à la qualité et à l'âge spécifiques de l'échantillon de matériau. Les résultats sont propres au produit.
Le présent document s'applique exclusivement aux granulés de biocombustibles solides.
Les informations déduites à l'aide du présent document sont destinées à être utilisées dans le contrôle qualité et dans l'identification des dangers et l'évaluation des risques associés aux procédures fournies dans l'ISO 20024:2020.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/ patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
