Overview
This document specifies three methods for the determination of the bulk density of granular refractory materials (grain density) having a grain size larger than 2 mm: - Method 1: mercury method with vacuum; - Method 2: arrested water absorption method; - Method 3: vacuum method with spin dryer option according to ISO 5017. The responsible German standardization committee is Working Committee NA 062-02-57 AA "Ungeformte, dichte geformte und wärmedämmende feuerfeste Erzeugnisse und Werkstoffe" ("Unshaped, dense shaped and insulating refractory products and materials") at DIN Standards Committee Materials Testing (NMP).
