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 document 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).

ISO takes no position concerning the evidence, validity or applicability of any claimed patent rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a) patent(s) which may be required to implement this document. However, implementers are cautioned that this may not represent the latest information, which may be obtained from the patent database available at www.iso.org/patents.

This document was prepared by Technical Committee ISO/TC 238, Solid biofuels and pyrogenic biocarbon, in collaboration with the European Committee for Standardization (CEN) Technical Committee CEN/TC 335, Solid biofuels and pyrogenic biocarbon, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).

This second edition cancels and replaces the first edition (ISO 17828:2015), which has been technically revised.

The main changes are as follows:

— introduction has been revised;
— dimensions of the small standardised container were modified to better reflect industry standard equipment, its volume has not changed;
— scope has been expanded to cover coarse fuels having a nominal top size larger than 63 mm;
— procedure for measuring bulk density of the newly included coarse fuels has been added;
— for newly included coarse fuels, a new measuring container has been defined;
— for fuels having a nominal top size of 63 mm and below, the optional use of an apparatus for controlled shock exposure is described; an example of such apparatus is added as informative Annex B;
— option to use a spill prevention aid has been included;
— rule for rounding reported result in the test report has been changed;
— test report clause has been revised.

Any feedback or questions on this document should be directed to the user’s national standards body. A complete listing of these bodies can be found at www.iso.org/members.html.
