This Technical Specification (CEN/TS) was approved by CEN on 27 March 2010 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.

Introduction
The metallic aluminium in solid recovered fuels is very problematic in combustion processes. Aluminium can
form deposit on heat transfer surfaces and superheaters. For these reasons a method for the determination
of total metallic aluminium is necessary. Other metals with low melting point such as tin, lead and zinc may
cause similar problems but their content in solid recovered fuels is usually very low and then their effect is
not significant.
1 Scope
This Technical Specification specifies two different methods for the determination of metallic aluminium in
solid recovered fuels:
 method a: dissolution of metallic aluminium and analysis by Inductively Coupled Plasma Optic Emission
Spectrometry (ICP-OES) or by Flame Atomic Absorption Spectrometry (FAAS);
 method b: Differential Thermal Analysis (DTA) on the solid SRF.

NOTE This includes the metallic aluminium and some chemical forms of aluminium non-soluble in nitric acid but
easily soluble in alkaline media.
4 Safety remarks
The safety in handling of potentially hazardous materials is dealt with relevant national and European
regulations, which every laboratory should refer to.
In addition the following information is given:
 most of reagents used within this Technical Specification are strongly corrosive and toxic. Safety
precautions are absolutely necessary due to strong corrosive reagents at high temperature;
 the reaction of metallic aluminium (and other metals such as zinc, lead and tin) with NaOH solution
generates gaseous hydrogen that can form explosive mixtures in the air;
