Popis
BS ISO 23028:2019
This standard BS ISO 23028:2019 Aluminium oxide primarily used for the production of aluminium. Preparation and storage of test samples is classified in these ICS categories:
- 71.100.10 Materials for aluminium production
This document describes methods for the sample preparation of smelter-grade aluminium oxide. It covers the reduction of a bulk sample between 1 kg and 20 kg to produce a sample that is suitable for chemical and physical analysis. The reduced sample produced will be representative of the initial bulk sample. The bulk sample is considered to be from one source.
The methods are suitable for dry, free-flowing aluminium oxide.
As the moisture content will influence many physical analyses, the method aims to minimize the exposure of the sample to the atmosphere to avoid water absorption.
