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.

Introduction
In the International Standards covering the analysis of solid biofuels, it is generally specified that the
determination is intended to be carried out on the air-dried or in air-equilibrated general analysis test
sample prepared according to ISO 14780. However, in making use of these analyses, it is necessary to
express the results on dry basis and sometimes, also on some other basis. The bases in common use for
solid biofuels are “air-dried” (sometimes stated as “as determined”), “as received” (sometimes stated
“as sampled” or “as delivered”), “dry”, and “dry, ash free”.

4 Principle
In order to convert an analytical result expressed as one basis to another basis, it is multiplied by a
factor calculated from the appropriate formulae (see Table 1), after insertion of the requisite numerical
values into the formula in question.
5 Calculations for analyses of solid biofuels
5.1 General
Most analytical values on a particular basis can be converted to any other basis by multiplying it by a
factor calculated from the appropriate formula given in Table 1, after insertion of the requisite numerical
values into the formula in question. However, for some parameters, there is a direct involvement of the
moisture content. In these cases, a correction (as specified in 5.2) of the air-dried result shall be carried
out before calculation to dry basis or dry, ash-free b
