This Technical Specification (CEN/TS) was approved by CEN on 11 January 2016 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, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia,

1 Scope
This Technical Specification specifies a method for determining the total moisture content of materials
obtained from End of Life Tyres (ELT) by drying samples in an oven. The method is applicable to chips,
granulates, powders and textile derived from the treatment of End of Life Tyres.
This document is not intended for the determination of moisture content in steel wires.

their dimension(s) and impurities and methods for determining their dimension(s) and impurities
3 Terms and definitions
For the purposes of this document, the terms and definitions given in CEN/TS 14243:2010 apply.
4 Principle
The sample of material is dried at a temperature of 105 °C in air atmosphere until constant mass is
reached. The percentage of moisture is calculated from the loss in mass of the sample. The method
includes a procedure for the correction of buoyancy effects.
5 Apparatus
5.1 Drying oven, capable of being controlled at (105 ± 2) °C (see declaration of the manufacturer)
and in which the air atmosphere changes between three and five times per hour.
The air velocity shall be such that the sample particles are not dislodged from their dish or tray (5.2).
5.2 Dishes or trays of non-corrodible and heat-resistant material and of such dimensions that they
2
are able to hold the total sample in the proportion of about 1 g of sample per 100 mm of surface area
2
of the dish or tray respectively or about 0,5 g per 100 mm for textile samples.
The surface of the dish or tray shall be such that the possibility to adsorption/absorption is minimized
(very clean and even surface).
5.3 Balance, capable of weighing the sample and dish or tray (5.2), as received, to the nearest 0,1 g.

6 Preparation of the sampling plan and laboratory sample
6.1 Principles of correct sampling
6.1.1 General
The main principle of sampling is to obtain a representative sample(s) from a lot of material from which
the moisture content shall be determined.
6.1.2 General
The objective of this procedure is to take samples in a way that is truly representative of the moisture
content of the material produced. It can be distinguished two different alternatives. Th
