ISO 23028 is applicable to aluminium oxide that describes methods for the sample preparation of smelter-grade aluminium oxide.
ISO 23028 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.
Note-
The methods are suitable for dry, free-flowing aluminium oxide.
ISO 23028 on preparation and storage of test samples of aluminium is useful for:
Aluminium oxide is used for the production of aluminium.
ISO 23028 provides you with principles, apparatus and procedures for the preparation and storage of test samples of aluminium.
The methods described in ISO 23028 helps you to minimize the exposure of the sample to the atmosphere to avoid water absorption.
