Solid biofuels - Determination of content of heavy extraneous materials larger than 3,15 mm (ISO 19743:2017)

This International Standard specifies a method for the determination of stone content of solid biofuels by the use of sink-and-float separation combined with elutriation. This International Standard is applicable to uncompressed solid biofuels, especially woody biomass (according to EN ISO 17225-1, Table 1), like wood chips and hog fuel.

Biogene Festbrennstoffe - Bestimmung des Gehaltes an schweren Fremdstoffen mit einer Partikelgröße von mehr als 3,15 mm (ISO 19743:2017)

Biocombustibles solides - Dosage de la teneur en matériaux lourds exogènes de dimension supérieure à 3,15 mm (ISO 19743:2017)

L'ISO 19743 :2017 spécifie une méthode de détermination de la teneur en matériaux lourds exogènes de dimension supérieure à 3,15 mm à l'aide d'une séparation par sédimentation et suspension avec élutriation. Le présent document est applicable à la biomasse ligneuse conformément à l'ISO 17225‑1:2014, Tableau 1.
NOTE 1    Cette méthode est conçue pour déterminer la teneur en impuretés de dimension supérieure à 3,15 mm et avec une masse volumique spécifique supérieure à 1 g/cm3 comme les pierres, le verre, le caoutchouc, le métal et certains types de matières plastiques.
NOTE 2    Lors du traitement de l'échantillon, un triage à la main des impuretés légères de masse volumique spécifique inférieure ou égale à 1 g/cm3 (par exemple une feuille plastique) peut également être effectué.

Trdna biogoriva - Določevanje tujih snovi, večjih od 3,15 mm (ISO 19743:2017)

Ta mednarodni standard določa metodo za ugotavljanje vsebnosti kamnin trdnih biogoriv z uporabo ločevanja s pomočjo težkih tekočin v kombinaciji z izpiranjem. Ta mednarodni standard se uporablja za nestisnjena trdna biogoriva, zlasti lesno biomaso (v skladu s standardom EN ISO 17225-1, preglednica 1), kot so lesni sekanci in drobljenci.

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.
