When purchasing lime for restoration work, design engineers, restorers or businessmen, in addition to choosing products based on their own particfular experience, also check that the label says, for example, "UNI EN 459-1 CL 90 S", indicating a purely calcic slaked lime, or "UNI EN 459-1 NHL 3.5", indicating medium hydraulic lime.

Abstract

When purchasing lime for restoration work, design engineers, restorers or businessmen, in addition to choosing products based on their own particfular experience, also check that the label says, for example, "UNI EN 459-1 CL 90 S", indicating a purely calcic slaked lime, or "UNI EN 459-1 NHL 3.5", indicating medium hydraulic lime. These indications allow the buyer to be reasonably sure the product is suited to his/her needs, partly because s/he considers the label and the marking that appears on ti as a guarantee of quality. Is it correct, however, to attribuite this function to the CE markiong and the standardised designation it contains? What are the limits to the guarantee it offers? Is it really possible to be certain that the material purchased is compliant with the requisites set by ther pertinent indications and indicated on the label? The aim of the article is to highlight the implications the technical requisites and certification system established by law for building limes sold in the EU can have on choosing a lime for restoration work.
