Test method for glass-fibre reinforced cement - Cyclic weathering type test1 Scope This European Standard specifies a test method for identifying, for a given GRC formulation (constituents and their proportions in the formulation), the effect of environmental factors such as water and temperature on the change of mechanical characteristics. For other conditions of exposure, e. g. where freezing, thawing and action of thawing salt occurs, the test will be adapted.

austenitic-ferritic grade 1

The method is applicable to most woven fabrics but is unsuitable for fabrics manufactured in such a way as to render removal of the crimp from the yarns impossible or impractical under the specified straightening tension

BS EN IEC 82079-1 has also been comprehensively revised to improve its clarity and ease of use
