General Information
Frequently Asked Questions
ISO/TC 33/WG 30 is a Working Group within the International Organization for Standardization (ISO). It is named "Determination of bulk density of granular materials (grain density)". This committee has published 1 standards.
ISO/TC 33/WG 30 develops ISO standards in the area of Information technology. Currently, there are 1 published standards from this working group.
The International Organization for Standardization (ISO) is an independent, non-governmental international organization that develops and publishes international standards. Founded in 1947 and headquartered in Geneva, Switzerland, ISO brings together experts from 170+ member countries to share knowledge and develop voluntary, consensus-based standards that support innovation and provide solutions to global challenges.
A Working Group in ISO is a specialized group responsible for developing standards or technical work within a defined scope. These bodies bring together international experts to create consensus-based standards that support global trade, safety, and interoperability.
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. Method 1 is intended as the reference method. NOTE Depending on the nature of the material tested, the three methods can give different results. Any statement of the value of a bulk density can therefore be accompanied by an indication of the method used or to be used in case of dispute. The same method can be used for the determination of the volume of the sample, for selecting and preparing the sample, for calculating the bulk density and for presenting the test report.
