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. When the total content exceeds 0,1 %, the actual types and amounts shall be declared.

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.
