European foreword
This document (prEN 459-2:2019) has been prepared by Technical Committee CEN/TC 51 “Cement and
building limes”, the secretariat of which is held by NBN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 492-2:2010.
In comparison with EN 459-2:2010, the following modifications have been:
— description of fusion with lithium tetraborate;
— a new Clause 4.1 included;
— amendments for the determinations of CaO and MgO;
— change of the order of methods for determination of CO ;
2
— Phenolphtalein as indicator replaced by thymolphtalein;
— 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.

Introduction
The objective in this document has been to adopt as many European standardized methods as possible,
and where this has not been possible, to use other appropriate proven methods.
Unless otherwise stated, tolerance class m of ISO 2768-1 apply (Indications on drawings by “ISO 2768-
m”).
All dimensions are in millimetres.

1 Scope
This document describes the test methods for all building limes covered by EN 459-1.
This document specifies in Table 2 the methods used for the chemical analyses and the determination of
physical properties of building limes.
This document describes primary methods of chemical analyses. The reference methods and, in certain
cases, alternative methods in this document can be considered to be equivalent.
