This Technical Specification (CEN/TS) was approved by CEN on 14 May 2018 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,
Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania,
Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland,
Turkey and United Kingdom.

European foreword
This document (CEN/TS 17216:2018) has been prepared by Technical Committee CEN/TC 351
“Construction products - Assessment of release of dangerous substances”, the secretariat of which is
held by NEN.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association.
According to the CEN/CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to announce this Technical Specification: Austria, Belgium, Bulgaria,
Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia,
France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta,
Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland,
Turkey and the United Kingdom.
Introduction
This document is a Technical Specification developed under Mandate M/366 issued by the European
Commission in the framework of the “Construction Products Directive” 89/106/EEC. This document
addresses the part of Mandate M/366 which provides for the preparation of horizontal
measurement/test methods for the determination of the activity concentrations of the radionuclides
radium-226, thorium-232 and potassium-40 in construction products using gamma-ray spectrometry.
Mandate M/366 is a complement to the product mandates issued by the European Commission to CEN
under the Construction Products Directive (CPD). The harmonized product standards (hEN) developed
in CEN under mandates (and ETAs developed in EOTA for products or kits) specify construction
product(s) as placed on the market and address their intended conditions of use.
The information produced by applying this Technical Specification can be used for purposes of CE
marking and evaluation/attestation of conformity. Product specification, standardization of
representative sampling and procedures for any product-specific laboratory sample preparation are the
responsibility of product TCs and are not covered in this Technical Specification.
This Technical Specification supports existing regulations and standardized practices, and is based on
methods described in standards, such as ISO 10703 [1], ISO 18589-2 [2], ISO 18589-3 [3] and NEN 5697
[4]. In summary, the Technical Specification describes the following:
— sampling, sub-sampling and test specimen preparation;
— measurement using gamma-ray spectrometry;
— background subtraction, energy and efficiency calibration, analysis of the spectrum;
— calculation of activity concentrations with associated uncertainties;
— reporting of test results.
Determination of the activity concentration is based on the principles of gamma-spectrometry, and
procedures for all stages of the testing are provided in this document. Although the tested material
sample rarely reflects a product’s form under its intended conditions of use, the measured activity
concentration is an intrinsic property of the material, which does not vary with the construction
product’s form. Consequently, the test results reflect the radiation behaviour of the product under its
intended use. In addition, the Technical Specification is intended to be non product-specific in scope,
with only a limited number of product-specific elements.
1 Scope
This document describes a test method for the determination of the activity concentrations of the
radionuclides radium-226, thorium-232 and potassium-40 in construction products using
semiconductor gamma-ray spectrometry.
This document describes sampling from a laboratory sample, sample preparation, and the sample
measurement by semiconductor gamma-ray spectrometry. It includes background subtraction, energy
and efficiency calibration, analysis of the spectrum, calculation of the activity concentrations with the
associated uncertainties, the decision threshold and detection limit, and reporting of the results. The
preparation of the laboratory sample from the initial product sample lies outside its scope and is
described in product standards.
This document is intended to be non product-specific in scope, however, there are a limited number of
product-specific elements such as the preparation of the laboratory sample and drying of the test
portion. The method is applicable to samples from products consisting of single or multiple material
components.
