Using this method to determine Vickers hardness from smaller indentations is outside the scope of this document as results would suffer from large uncertainties due to the limitations of optical measurement and imperfections in tip geometry

Determination of the uplift resistance of clay or concrete tiles for roofing. Roof system test method Ingestion-build-71203 and ISO 14520-1:20151 Scope This document specifies a test method to establish the uplift resistance of installed clay or concrete tiles for roofing, complying with the relevant product standard, EN 490 or EN 1304, which are unfixed or mechanically fixed to the substructure. NOTE The test method has been developed for clay or concrete tiles for roofing but may apply to other discontinuously laid small elements, such as: slates; fibre cement slates; and, stones. The test
