3 Terms and Definitions
For the purposes of this Standard, the following terms and definitions apply.
3.1
Silica proppant
Solid particles matters with high-strength and used for the support of fracturing operation, also referred to as fracturing proppant. Native silica sand and artificial sintered bauxite ceramsite may be served as fracturing proppant.
3.2
Sphericity
Particle sphericity is a measure of how closely a sand particle or grain approaches the shape of a sphere.
