English version
Solid biofuels - Method for the determination of ash content
Feste Biobrennstoffe - Verfahren zur Bestimmung des
Aschegehaltes
This Technical Specification (CEN/TS) was approved by CEN on 5 February 2004 for provisional application.
The period of validity of this CEN/TS is limited initially to three years. After two years the members of CEN will be requested to submit their
comments, particularly on the question whether the CEN/TS can be converted into a European Standard.
CEN members are required to announce the existence of this CEN/TS in the same way as for an EN and to make the CEN/TS available
promptly at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in parallel to the CEN/TS)
until the final decision about the possible conversion of the CEN/TS into an EN is reached.
CEN members are the national standards bodies of Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France,
Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia,
Slovenia, Spain, Sweden, Switzerland and United Kingdom.

1 Scope
This document specifies a method for the determination of ash content of all solid biofuels (CEN/TS 14588).
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.

prCEN/TS 14780, Solid Biofuels – Methods for sample reduction

3 Terms and definitions
For the purpose of this document, the terms and definitions given in CEN/TS 14588:2003 and the following
apply.

3.1
Ash content, dry basis
Mass of inorganic residue remaining after ignition of a fuel under specified conditions expressed as a
percentage of the mass of the dry matter in the fuel

4 Principle
The ash content is determined by calculation from the mass of the residue remaining after the sample is
heated in air under rigidly controlled conditions of time, sample weight and equipment specifications to a
controlled temperature of (550±10) °C.
NOTE Difference in the ash content determined at a higher temperature, 815 °C, according to ISO 1171-1997,
compared to 550 °C can be explained by the loss of volatile inorganic compounds, further oxidation (higher oxidation
state) of inorganic compounds and the decomposition of carbo
