DIN EN ISO 1927-8:2013-04

This document describes methods for determination of the properties of unshaped refractory materials from test pieces prepared and stored in accordance with EN ISO 1927-5. The methods complement those described in EN ISO 1927-6. The methods have been adapted from standards for shaped refractory products to make them applicable to dense and insulating castables, plastic materials and ramming mixes as defined in ISO 1927-1, before and after firing.
