This Technical Specification (CEN/TS) was approved by CEN on 31 October 2011 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, 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 16305:2012) has been prepared by Technical Committee CEN/TC 260 “Fertilizers
and liming materials”, 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.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to announce this Technical Specification: Austria, Belgium, Bulgaria, Croatia, 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, Turkey and the United Kingdom.
Introduction
A standard method for the determination of the dust content of granulated liming materials is required to
indicate the stability and quality of the product and to simulate the dust produced during handling and storage.
A rotating device is used to simulate the abrasion caused by handling.
1 Scope
This European Standard specifies a method for the determination of the amount of dust in granulated liming
materials, both before and after simulated handling conditions.
This method applies to all granulated and screened liming materials.

references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.

4 Principle
Dry sieving of a granulated liming material using a mechanical sieve. Abrasion using a Mechanical Rotating
Device (MRD). Dry sieving of the product from the MRD using a mechanical sieve. Determination of the
content of dust (i. e. material below 1 mm) before and after abrasion.
