Solid biofuels - Determination of particle size distribution for uncompressed fuel- Part 2: Vibrating screen method using sieves with aperture of 3,15 mm and below (ISO 17827-2:2016)
This international standard describes method for determination of the the size distribution of particulate biofuels by the
horizontally oscillating screen method. It applies to particulate uncompressed fuels with a nominal top size of 1 mm and
above such as wood chips, hog fuel, olive stones etc. A sample is subjected to sieving through horizontally oscillating
sieves, sorting the particles in decreasing size classes by mechanical means.The sieving operation shall be horizontally
oscillating (one or two dimensional), using an appropriate stroke-frequency according to the type of material. The number of
sieves and the aperture sizes of the sieves shall be chosen according to the size specification of the actual sample material.
Biogene Festbrennstoffe - Bestimmung der Partikelgrößenverteilung für unkomprimierte Brennstoffe - Teil 2: Vertikales Rüttelsiebverfahren mit Sieben zur Klassifizierung von Proben mit einer Höchst-Sieb-Lochgröße von 3,15 mm und darunter (ISO 17827-2:2016)
Dieses Teil der ISO 17827 legt ein Verfahren zur Bestimmung der Größenverteilung von biogenen Brennstoffen als Schüttgut durch das Rüttelsiebverfahren fest. Das beschriebene Verfahren ist ausschließlich für biogene Brennstoffe als Schüttgut vorgesehen, d. h. Materialien, die entweder in ihrer Größe reduziert worden sind, so wie die meisten Holzbrennstoffe, oder die als Schüttgut vorliegen. Dieses Teil der ISO 17827 gilt für unkomprimierte Brennstoffe in Form von Schüttgut mit einer nominellen Siebgröße von 3,5 mm und weniger (z. B. Sägespäne).
Biocombustibles solides - Détermination de la distribution granulométrique des combustibles non comprimés - Partie 2: Méthode au tamis vibrant d'ouverture de maille inférieure ou égale à 3,15 mm (ISO 17827-2:2016)
ISO 17827-2:2016 spécifie une méthode de détermination de la distribution granulométrique des biocombustibles particulaires à l'aide d'un tamis vibrant. La méthode décrite est destinée uniquement aux biocombustibles particulaires, c'est-à-dire à des matériaux qui ont été fragmentés, comme la plupart des combustibles ligneux, ou qui se présentent physiquement sous forme particulaire. La présente partie de l'ISO 17827 s'applique aux combustibles particulaires non comprimés de dimension supérieure nominale inférieure ou égale à 3,15 mm (par exemple la sciure).
Trdna biogoriva - Določevanje porazdelitve velikosti delcev za nekomprimirana goriva - 2. del: Metoda z vibracijskim sitom z odprtinami 3,15 mm in manj (ISO 17827-2:2016)
Ta mednarodni standard opisuje metodo za določanje porazdelitve velikosti delcev biogoriv z metodo z vodoravno nihajočim sitom. Uporablja se za nestisnjena goriva z nazivno zrnatostjo vsaj 1 mm, kot so lesni sekanci, drobljenci, olivne koščice itd. Vzorec se preseje skozi vodoravno nihajoča sita, ki mehansko razvrstijo delce po velikosti od največjih do najmanjših. Sejanje mora potekati z vodoravno nihajočim premikanjem (eno- ali dvodimenzionalno) in uporabo ustrezne frekvence sunkov skladno z vrsto materiala. Število sit in velikosti njihovih odprtin je treba izbrati v skladu s specifikacijo velikosti dejanskega vzorčnega materiala.

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

mm and below
1 Scope
This part of ISO 17827 specifies a method for the determination of the size distribution of particulate
biofuels by the vibrating screen method. The method described is meant for particulate biofuels only,
namely, materials that either have been reduced in size, such as most wood fuels, or are physically in a
particulate form. This part of ISO 17827 applies to particulate uncompressed fuels with a nominal top
size of 3,15 mm and below (e.g. sawdust).
