3 Terms and Definitions
3.1
When immersed in water, the water can penetrate into the pores.
3.2
When immersed in water, the water can not penetrate into the pores.
3.3
In addition to the quality of dried material in the apparent volume (3.4) results obtained.
3.4
Volume compact, its size is determined by the volume of water after dipping alternatives saturated water surface drying determined.
Note. The apparent volume including the volume of solid compact, open porosity (3.1) and closed pores (3.2) volume.
3.5
Mass of dry matter in the openings (3.1) absorbed water mass fraction of dry material representation.
4 Sampling and Sample Preparation
Hot briquette iron (HBI) sampling and sample preparation should follow the general and basic principles GB/T 10322.1 and the ISO 10835. Test samples should
Ensure that sufficient quantities should contain at least 100 hot briquette iron.
