This European Standard applies to hydraulic binder for non-structural applications in construction used as binder for preparation of mortar for masonry, rendering and plastering and other non-structural construction products. This European Standard specifies the definition and composition of hydraulic binder for non-structural applications (HB). It includes physical, mechanical and chemical requirements and defines strength classes. EN 15368 also states the conformity criteria and the related rules. Necessary durability requirements are also given. NOTE For normal applications the information given in this standard, and in the masonry specifications, EN 998-1 and EN 998-2, is generally sufficient. However, in special cases, an exchange of additional information between the producer and user can be helpful. The details of such an exchange are not within the scope of this standard but should be dealt with in accordance with national standards or other regulations or can be agreed between
