This European Standard applies to building limes used as binders for preparation of mortar (for masonry, rendering and plastering) and production of other construction products. It gives definitions for the different types of building limes 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 lime, are outside the scope of this European Standard. NOTE Additional requirements are needed in special applications e. g. civil engineering.
