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. SIST EN 459-1:2010

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.

For quicklime these values correspond to the finished product; for all other forms of lime (hydrated lime, lime putty and milk of lime) the values are based on the product after subtraction of its free water and bound water content. The values for available lime (calcium oxide for quicklime, calcium hydroxide for hydrated lime) refer to the product when tested in accordance with EN 459-2. a MgO content up to 7 % is permitted if the soundness test in accordance with EN 459-2 is passed. b A higher content of CO2 is permitted, if all other chemical requirements in Table 2 are satisfied and the test frequency satisfies the requirements in Table 7. c Higher values of available lime may be requested.
