Impact value test determines the amount of energy absorbed by a material during fracture. This absorbed energy gives a measure of toughness of a given material and acts as a tool to study temperature-dependent brittle-ductile transition. It is used to determine whether the material is brittle or ductile in nature.

This Part of BS 812 describes the method for determining the polished stone value (PSV) of an aggregate. The PSV gives a measure of the resistance of roadstone to the polishing action of vehicle tyres under conditions similar to those occurring on the surface of a road. The test is in two parts. In part one of the test, samples of stone are ...

Abstract. Results of a European round-robin aiming to identify and quantify scattering sources impacting the polished stone value (PSV) of aggregates, and to assess the reference PSV of Herrnholzer granite, are presented and discussed. This reference value corrected against quartz dolerite control stone is calculated as PSV ref HE = 56.1 ± 0.5.

Reference Table for "U" Values "U" Value is the coefficient of transmission, i.e., the transmission of heat through the materials, which compose the building's "envelope," or outer shell. "U" Value has an inverse relationship to "R" Value. For example, a building with material with an "R" Value of R-11 converts to an "U" Value of 0.09 ( 1/R or 1/11 = 0.09).
