This Technical Specification (CEN/TS) was approved by CEN on 25 March 2006 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, Romania,

Foreword
This document (CEN/TS 15407:2006) has been prepared by Technical Committee CEN/TC 343 “Solid
Recovered Fuels”, the secretariat of which is held by SFS.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to announce this CEN Technical Specification: Austria, Belgium, Cyprus, Czech Republic,
Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania,
Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden,
Switzerland and United Kingdom.
Introduction
The determination of carbon, hydrogen and nitrogen is usually performed using instrumental methods. The
latter can be divided in two groups depending on the amount of test portion used. Micro instrumental methods
require few mg of sample; macro methods use grams of sample. If micro methods are used for SRF analysis,
a very homogeneous test sample needs to be prepared in order to obtain the required precision.
1 Scope
This Technical Specification describes a method for the determination of total carbon, hydrogen and nitrogen
contents in solid recovered fuels by instrumental techniques.
This method is applicable for concentrations on dry matter basis of C over 0,1 %, N over 0,01 % and H over
0,1 %.
2 Normative references
The following referenced documents are indispensable for the application of this Technical Specification. For
dated references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.

sample

3 Terms and definitions
For the purposes of this Technical Specification, the terms and definitions given in CEN/TS 15357:2006 apply.
4 Safety remarks
The safety in handling of potentially hazardous materials is dealt with in relevant national and European
regulations, which every laboratory should refer to.
In addition the following information is given:
instruments for carbon, hydrogen and nitrogen determination shall be used only by experienced
personnel, following the safety instructions of the manufacturer.
5 Principle
The method is based on the complete oxidation of the sample ("flash combustion" instruments can also be
used) which converts all organic substances into combustion products. The resulting combustion gases pass
through a reduction furnace and are swept into the chromatographic column by the carrier gas (helium) where
they are separated and detected quantitatively by appropriate instrumental gas analysis procedures (for
example by a thermal conductivity detector (TCD)). The samples are held in a suitable container (tin or other
crucible) and then dropped inside the quartz tube furnace at about 1000 °C in an oxygen stream for complete
oxidation in the presence of a catalyst layer. Excess oxygen is removed by contact with copper, while nitrogen
oxides are reduced to elemental nitrogen.
6 Reagents and calibration standards
All reagents shall be at least of analytical grade and suitable for their specific purposes.
6.1 Carrier gas: Helium, 99,99 % or other gases as specified by the instrument manufacturer.
6.2 Oxygen, free of combustion material, purity 99,95 %, or as specified by the instrument
