SPÉCIFICATION TECHNIQUE

TECHNISCHE SPEZIFIKATION
May 2013
ICS 13.030.01
English Version
Sludge, treated biowaste and soil - Determination of specific
electrical conductivity
Boues, biodéchets traités et sols - Détermination de la Schlamm, behandelter Bioabfall und Boden - Bestimmung
conductivité électrique spécifique der spezifischen elektrischen Leitfähigkeit
This Technical Specification (CEN/TS) was approved by CEN on 16 July 2012 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, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and United
Kingdom.

Foreword
This document (CEN/TS 15937:2013) has been prepared by Technical Committee CEN/TC 400 “Project
Committee - Horizontal standards in the fields of sludge, biowaste and soil”, the secretariat of which is held by
DIN.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights.
The preparation of this document by CEN is based on a mandate by the European Commission (Mandate
M/330), which assigned the development of standards on sampling and analytical methods for hygienic and
biological parameters as well as inorganic and organic determinants, aiming to make these standards
applicable to sludge, treated biowaste and soil as far as this is technically feasible.
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, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

Introduction
The determination of the specific electrical conductivity is carried out to obtain an indication of the content of
water-soluble electrolytes in soil, treated biowaste and sludge.
WARNING — Persons using this Technical Specification should be familiar with usual laboratory
practice. This Technical Specification does not purport to address all of the safety problems, if any,
associated with its use. It is the responsibility of the user to establish appropriate safety and health
practices and to ensure compliance with any national regulatory conditions.
IMPORTANT — It is absolutely essential that tests conducted according to this Technical
Specification be carried out by suitably trained staff.
