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. This document supersedes EN 459-1:2010. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association. For relationship with Regulation (EU) No. 305/2011, see informative Annex ZA, which is an integral part of this document. EN 459, Building lime, consists of the following parts: — Part 1: Definitions, specifications and conformity criteria; — Part 2: Test methods; — Part 3: Conformity evaluation. The requirements in EN 459-1 are based on the results of tests on building lime determined in accordance with EN 459-2.

According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: 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. SIST EN 459-1:2015

EN 459-1:2015 (E) 4 Introduction The revision of this European Standard for building lime was initiated by Decision 4 taken by CEN/TC 51 “Cement and building limes” in 2013. Different sources of raw materials and different climatic conditions have led to different developments in building construction and civil engineering practices and materials and therefore to different kinds of building lime in different regions of Europe. The inclusion of a wider range of building lime which exists in Europe has made it necessary to establish a number of classes. The previous national standards for building lime generally also formed the basis for different areas of application (see Annex C (informative)). The classification chosen therefore also takes into consideration these circumstances as far as possible. For a better understanding, the standard makes a clear distinction between air lime (Clause 4) and lime with hydraulic properties (Clause 5). Depending on the composition and characteristics of the products, each clause is then divided into sub-paragraphs (calcium lime and dolomitic lime for air lime; natural hydraulic lime, formulated lime and hydraulic lime for lime with hydraulic properties) containing the appropriate definitions, specifications and conformity criteria. SIST EN 459-1:2015

EN 459-1:2015 (E) 5 1 Scope This European Standard applies to building lime used for: — preparation of binder for mortar (for example for masonry, rendering and plastering); — production of other construction products (for example calcium silicate bricks, autoclaved aerated concrete, concrete, etc.); — civil engineering applications (for example soil treatment, asphalt mixtures, etc.). It gives definitions for the different types of building lime and their classification. It also gives requirements for their chemical and physical properties which depend on the type of building lime and specifies the conformity criteria. Terms of delivery or other contractual conditions, normally included in documents exchanged between the supplier and the purchaser of building lime, are outside the scope of this European Standard. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

Reaction with atmospheric carbon dioxide is part of the hardening process. Lime with hydraulic properties is divided into three sub-families, natural hydraulic lime (NHL), formulated lime (FL) and hydraulic lime (HL). 3.5 allowable probability of acceptance CR for a given sampling plan, allowed probability of acceptance of building lime with a characteristic value outside the specified characteristic value 3.6 sampling plan specific plan which states the (statistical) sample size(s) to be used, the percentile Pk and the allowable probability of acceptance CR 3.7 characteristic value value of a required property outside which lies a specified percentage, the percentile Pk, of all the values of the population 3.8 specified characteristic value characteristic value of a strength, physical or chemical property which in the case of an upper limit is not to be exceeded or in the case of a lower limit is, as a minimum, to be reached 3.9 single result limit value value of a strength, physical or chemical property which − for any single test result − in the case of an upper limit is not be exceeded or in the case of a lower limit is, as a minimum, to be reached 3.10 spot sample sample taken at the same time and from one and the same place, relating to the intended tests Note 1 to entry: It can be obtained by combining one or more immediately consecutive increments (see EN 459–2). 3.11 autocontrol testing continual testing by the manufacturer of building lime spot samples taken at the point(s) of release from the factory/depot 3.12 control period period of production and dispatch identified for the evaluation of the autocontrol test results 4 Air lime 4.1 General Air lime is used for the preparation or the production of materials used in building construction as well as in civil engineering. SIST EN 459-1:2015

EN 459-1:2015 (E) 7 Air lime (see 3.3) when appropriately batched and mixed with water, forms a paste that improves the workability (values of flow and penetration) and water retention of mortars. The carbonation of hydrates in contact with atmospheric carbon dioxide forms calcium carbonate which develops strength and contributes to the durability of mortars containing building lime (hence the name of air lime). Sub-families and forms of air lime are given in 4.2 and 4.3 respectively. 4.2 Sub-families of air lime 4.2.1 Calcium lime (CL) Calcium lime is an air lime consisting mainly of calcium oxide and/or calcium hydroxide without any hydraulic or pozzolanic addition. 4.2.2 Dolomitic lime (DL) Dolomitic lime is an air lime consisting mainly of calcium magnesium oxide and/or calcium magnesium hydroxide without any hydraulic or pozzolanic addition. 4.3 Forms of air lime 4.3.1 Quicklime (Q) Quicklime is an air lime mainly in the oxide form which reacts exothermically on contact with water. Quicklime is available in a range of sizes from lump to powder. 4.3.2 Hydrated lime (S, S PL or S ML) Hydrated lime is an air lime mainly in the hydroxide form produced by the controlled slaking of quicklime. Hydrated lime is available as: — powder (S); — putty (S PL); or — slurry or milk of lime (S ML). Dolomitic lime is also produced as semi-hydrated dolomitic lime (S1), mainly consisting of calcium hydroxide and magnesium oxide. 4.4 Calcium lime 4.4.1 Classification of calcium lime Calcium lime shall be classified according to the notation given in Table 1 and its total (CaO + MgO) content in accordance with Table 2. SIST EN 459-1:2015

EN 459-1:2015 (E) 8 Table 1 — Types of calcium lime a Designation Notation Calcium lime 90 CL 90 Calcium lime 80 CL 80 Calcium lime 70 CL 70 a In addition, calcium lime is classified according to the form of the product, quicklime (Q), hydrated lime (S), lime putty (S PL) or milk of lime (S ML).

Conformity with this classification is assessed by means of statistical quality control as described in Annex A of this European Standard. 4.4.2 Chemical requirements for calcium lime The properties of the type of calcium lime shown in Table 2 determined in accordance with EN 459-2 shall conform to the requirements in that table. All types of calcium lime listed in Table 2 may contain additives in small quantities to improve the manufacture or properties of calcium lime.

EN 459-1:2015 (E) 11 4.4.8 Assessment and verification of constancy of performance of calcium lime 4.4.8.1 General requirements Conformity of calcium lime to this European Standard shall be continuously evaluated on the basis of testing of spot samples. The properties to be tested for the autocontrol testing by the manufacturer, test methods and the minimum testing frequencies for each type of calcium lime detailed in Table 1 are specified in Table 7. The declaration of performance by the manufacturer, shall be based on the assessment and verification of constancy of performance of building lime with this European Standard according to the scheme specified in EN 459-3. Requirements for the declaration of performance which the manufacturer should make available under the CE marking procedure are established in Annex ZA. 4.4.8.2 Conformity requirements Sampling shall take place at the point of release of the building lime. Conformity of calcium lime with the requirements concerning chemical and physical properties in this European Standard is assumed if the requirements in Tables 2 to 6 inclusive are met. The requirements in these tables shall be taken as absolute values. The evaluation procedure depends on the frequency of testing during the control period of 12 months. If the number of samples is at least one per week, the evaluation may be statistical (characteristic values) (see Annex A). Statistical evaluation is normally carried out by attributes (see Table 7 and A.1.3). If the data are normally distributed, the evaluation may be made by variables (see Table 7 and A.1.2). NOTE This standard does not deal with acceptance inspection at delivery.

If the test frequency of available lime and CO2 is higher than the required frequency (e.g. available lime > 1/week and CO2 > 1/week) then the test frequency of CaO + MgO may be reduced to twice per year. g For hydrated lime: If 30 consecutive test results are less than 10 % of the required value then the test frequency may be reduced to once per month. If any single result is higher than 10 % of the required value then return to daily testing. For quicklime: If 30 consecutive test results meet the requirement, then the test frequency may be reduced to once per month. If any single result fails the requirement, then return to daily testing. h If the data are not normally distributed the evaluation shall be made by attributes. j If the number of samples taken during the control period is at least one per week the evaluation may be made by variables. k For lime without additives this test is required only for product type determination. l See EN 459–3:2015, 4.4. m See Table 6, Footnote g. n See Table 2, Footnote b. o See Table 2, Footnote c.

FprEN 459-1:2014 (E) 3 Foreword This document (FprEN 459-1:2014) 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 Unique Acceptance Procedure. This document will supersede EN 459-1:2010. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of Regulation (EU) No. 305/2011. For relationship with Regulation (EU) No. 305/2011, see informative Annex ZA, which is an integral part of this document. The European Standard EN 459 for Building lime consists of the following parts: — Part 1: Definitions, specifications and conformity criteria; — Part 2: Test methods; — Part 3: Conformity evaluation. The requirements in EN 459-1 are based on the results of tests on building lime determined in accordance with EN 459-2.

Note: Due to fact that the Framework Partnership Agreement between the Commission and CEN and CENELEC is not signed yet, there are currently no New Approach Consultants in place for 2014. Therefore the provisions of CEN-CENELEC Guide 15 cannot be met. This shall not prevent the processing of draft standards nor the offering of harmonized standards to the Commission. In particular, draft standards can be sent to vote without Consultant assessment. This note will be removed from the Foreword of the finalized publication.

FprEN 459-1:2014 (E) 4 Introduction The revision of this European Standard for building lime was initiated by Decision 4 taken by CEN/TC 51 “Cement and building limes” in 2013. Different sources of raw materials and different climatic conditions have led to different developments in building construction and civil engineering practices and materials and therefore to different kinds of building lime in different regions of Europe. The inclusion of a wider range of building lime which exists in Europe has made it necessary to establish a number of classes. The previous national standards for building lime generally also formed the basis for different areas of application (see Annex C (informative)). The classification chosen therefore also takes into consideration these circumstances as far as possible. For a better understanding, the standard makes a clear distinction between air lime (Clause 4) and lime with hydraulic properties (Clause 5). Depending on the composition and characteristics of the products, each clause is then divided into sub-paragraphs (calcium lime and dolomitic lime for air lime; natural hydraulic lime, formulated lime and hydraulic lime for lime with hydraulic properties) containing the appropriate definitions, specifications and conformity criteria. kSIST FprEN 459-1:2014

FprEN 459-1:2014 (E) 5 1 Scope This European Standard applies to building lime used for: — preparation of binder for mortar (for example for masonry, rendering and plastering); — production of other construction products (for example calcium silicate bricks, autoclaved aerated concrete, concrete, etc.); — civil engineering applications (for example soil treatment, asphalt mixtures, etc.). It gives definitions for the different types of building lime and their classification. It also gives requirements for their chemical and physical properties which depend on the type of building lime and specifies the conformity criteria. Terms of delivery or other contractual conditions, normally included in documents exchanged between the supplier and the purchaser of building lime, are outside the scope of this European Standard. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

Reaction with atmospheric carbon dioxide is part of the hardening process. Lime with hydraulic properties is divided into three sub-families, natural hydraulic lime (NHL), formulated lime (FL) and hydraulic lime (HL). 3.5 allowable probability of acceptance CR for a given sampling plan, allowed probability of acceptance of building lime with a characteristic value outside the specified characteristic value 3.6 sampling plan specific plan which states the (statistical) sample size(s) to be used, the percentile Pk and the allowable probability of acceptance CR 3.7 characteristic value value of a required property outside which lies a specified percentage, the percentile Pk, of all the values of the population 3.8 specified characteristic value characteristic value of a strength, physical or chemical property which in the case of an upper limit is not to be exceeded or in the case of a lower limit is, as a minimum, to be reached 3.9 single result limit value value of a strength, physical or chemical property which − for any single test result − in the case of an upper limit is not be exceeded or in the case of a lower limit is, as a minimum, to be reached 3.10 spot sample sample taken at the same time and from one and the same place, relating to the intended tests Note 1 to entry: It can be obtained by combining one or more immediately consecutive increments (see EN 459–2). 3.11 autocontrol testing continual testing by the manufacturer of building lime spot samples taken at the point(s) of release from the factory/depot 3.12 control period period of production and dispatch identified for the evaluation of the autocontrol test results 4 Air lime 4.1 General Air lime is used for the preparation or the production of materials used in building construction as well as in civil engineering. kSIST FprEN 459-1:2014

FprEN 459-1:2014 (E) 7 Air lime (see 3.3) when appropriately batched and mixed with water, forms a paste that improves the workability (values of flow and penetration) and water retention of mortars. The carbonation of hydrates in contact with atmospheric carbon dioxide forms calcium carbonate which develops strength and contributes to the durability of mortars containing building lime (hence the name of air lime). Sub-families and forms of air lime are given in 4.2 and 4.3 respectively. 4.2 Sub-families of air lime 4.2.1 Calcium lime (CL) Calcium lime is an air lime consisting mainly of calcium oxide and/or calcium hydroxide without any hydraulic or pozzolanic addition. 4.2.2 Dolomitic lime (DL) Dolomitic lime is an air lime consisting mainly of calcium magnesium oxide and/or calcium magnesium hydroxide without any hydraulic or pozzolanic addition. 4.3 Forms of air lime 4.3.1 Quicklime (Q) Quicklime is an air lime mainly in the oxide form which reacts exothermically on contact with water. Quicklime is available in a range of sizes from lump to powder. 4.3.2 Hydrated lime (S, S PL or S ML) Hydrated lime is an air lime mainly in the hydroxide form produced by the controlled slaking of quicklime. Hydrated lime is available as: — powder (S); — putty (S PL); or — slurry or milk of lime (S ML). Dolomitic lime is also produced as semi-hydrated dolomitic lime (S1), mainly consisting of calcium hydroxide and magnesium oxide. 4.4 Calcium lime 4.4.1 Classification of calcium lime Calcium lime shall be classified according to the notation given in Table 1 and its total (CaO + MgO) content in accordance with Table 2. kSIST FprEN 459-1:2014

FprEN 459-1:2014 (E) 11 4.4.8 Assessment and verification of constancy of performance of calcium lime 4.4.8.1 General requirements Conformity of calcium lime to this European Standard shall be continuously evaluated on the basis of testing of spot samples. The properties to be tested for the autocontrol testing by the manufacturer, test methods and the minimum testing frequencies for each type of calcium lime detailed in Table 1 are specified in Table 7. The declaration of performance by the manufacturer, shall be based on the assessment and verification of constancy of performance of building lime with this European Standard according to the scheme specified in EN 459-3. Requirements for the declaration of performance which the manufacturer should make available under the CE marking procedure are established in Annex ZA. 4.4.8.2 Conformity requirements Sampling shall take place at the point of release of the building lime. Conformity of calcium lime with the requirements concerning chemical and physical properties in this European Standard is assumed if the requirements in Tables 2 to 6 inclusive are met. The requirements in these tables shall be taken as absolute values. The evaluation procedure depends on the frequency of testing during the control period of 12 months. If the number of samples is at least one per week, the evaluation may be statistical (characteristic values) (see Annex A). Statistical evaluation is normally carried out by attributes (see Table 7 and A.1.3). If the data are normally distributed, the evaluation may be made by variables (see Table 7 and A.1.2). NOTE This standard does not deal with acceptance inspection at delivery.

If the test frequency of available lime and CO2 is higher than the required frequency (e.g. available lime > 1/week and CO2 > 1/week) then the test frequency of CaO + MgO may be reduced to twice per year. g For hydrated lime: If 30 consecutive test results are less than 10 % of the required value then the test frequency may be reduced to once per month. If any single result is higher than 10 % of the required value then return to daily testing. For quicklime: If 30 consecutive test results meet the requirement, then the test frequency may be reduced to once per month. If any single result fails the requirement, then return to daily testing. h If the data are not normally distributed the evaluation shall be made by attributes. j If the number of samples taken during the control period is at least one per week the evaluation may be made by variables. k For lime without additives this test is required only for product type determination. l See EN 459–3:2015, 4.4. m See Table 6, Footnote g. n See Table 2, Footnote b. o See Table 2, Footnote c.
