Solid biofuels - Determination of total content of sulfur and chlorine (ISO 16994:2016)

ISO 16994:2016 describes methods for the determination of the total sulfur and total chlorine content in solid biofuels. It specifies two methods for decomposition of the fuel and different analytical techniques for the quantification of the elements in the decomposition solutions. The use of automatic equipment is also included in ISO 16994:2016, provided that a validation is carried out as specified and that the performance characteristics are similar to those of the method described in ISO 16994:2016.

Biogene Festbrennstoffe - Bestimmung des Gesamtgehaltes an Schwefel und Chlor (ISO 16994:2016)

Diese Internationale Norm beschreibt Verfahren zur Bestimmung des Gesamtgehaltes an Schwefel und an Chlor in biogenen Festbrennstoffen. Diese Internationale Norm legt zwei Verfahren für den Aufschluss des Brennstoffs und verschiedene Analysenverfahren für die quantitative Bestimmung der Elemente in den Aufschlusslösungen fest. Der Einsatz automatischer Geräte ist in dieser Internationalen Norm ebenfalls enthalten, sofern eine Validierung, wie im Dokument festgelegt, durchgeführt wird, und die Leistungsdaten denen des in dieser Internationalen Norm beschriebenen Verfahrens ähnlich sind.

Biocombustibles solides - Détermination de la teneur totale en soufre et en chlore (ISO 16994:2016)

L'ISO 16994 :2016 décrit des méthodes de détermination de la teneur totale en soufre et en chlore des biocombustibles solides. Elle spécifie deux méthodes de décomposition du combustible et différentes techniques d'analyse pour la quantification des éléments présents dans les solutions de décomposition. Elle englobe également l'utilisation d'équipements automatiques sous réserve que la validation soit effectuée conformément aux spécifications et que les caractéristiques de performance soient similaires à celles de la méthode décrite dans l'ISO 16994 :2016.

Trdna biogoriva - Določevanje celotnega žvepla in klora (ISO 16994:2016)

Ta mednarodni standard opisuje metode za določevanje celotnega žvepla in klora v trdnih biogorivih. Ta mednarodni standard določa dve metodi za razkrajanje
goriva in različne analizne tehnike za kvantifikacijo elementov v
rešitvah razkrajanja. V tem mednarodnem standardu je vključena tudi uporaba avtomatske opreme pod pogojem, da je potrjevanje izvedeno, kot je opredeljeno, in da so lastnosti podobne lastnostim metode, opisane v tem mednarodnem standardu.

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.
For an explanation on the meaning of ISO specific terms and expressions related to conformity
assessment, as well as information about ISO’s adherence to the WTO principles in the Technical
Barriers to Trade (TBT) see the following URL: Foreword - Supplementary information.
The committee responsible for this document is ISO/TC 238, Solid biofuels.
This second edition cancels and replaces the first edition (ISO 16994:2015), of which it constitutes a
minor revision.
