European foreword
This document (EN 459-2:2021) has been prepared by Technical Committee CEN/TC 51 “Cement and
building limes”, the secretariat of which is held by NBN.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by January 2022, and conflicting national standards shall
be withdrawn at the latest by January 2022.
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 supersedes EN 459-2:2010.
In comparison with EN 459-2:2010, the following modifications have been made:
— description of fusion with lithium tetraborate;
— a new Clause 5.1 included;
— amendments for the determinations of CaO and MgO;
— change of the order of methods for determination of CO ;
2
— Phenolphthalein as indicator replaced by thymolphthalein;
— Amendments for the determination of available lime;
— amendments of the methods for particle size determination;
— amendment for the description of bulk density;
— amendments for the determination of reactivity;
— amendments for the Table B.1 and Table B.2 in Annex B;
— editorial changes were made and minor mistakes corrected.
EN 459, Building lime, is currently composed of the following parts:
— Part 1: Definitions, specifications and conformity criteria;
— Part 2: Test methods;
— Part 3: Conformity evaluation.
The existing standards from the EN 196 series were used as a basis for the testing of physical and
mechanical properties in EN 459-2. For the testing of chemical properties of building limes, test
methods described in EN 12485 have been incorporated into this document.
