3 Terms and definitions

The terms and definitions defined in LY/T 2483-2015 and the following apply to this document. 3.1 Bamboo charcoal powder Bamboo charcoal that has been crushed or ground to a particle size less than or equal to 1 mm. 3.2 Small pieces and crushed bamboo charcoal, bamboo charcoal with particle size greater than 1mm.

4 Test methods

4.1 Determination of density 4.1.1 Particle density 4.1.1.1 Method Summary For irregular bamboo charcoal particles, according to Archimedes principle, a solid density meter (composed of an electronic balance, density software, density accessories, etc.) is used. The density of bamboo charcoal is measured by a combination of an instrument and a charcoal granule. The larger the size of the charcoal, the more it can be broken up before measurement. The charcoal in the form of a cylinder or sheet can also be measured. ......
