Fragment classification and measurement procedures.

Number	Category	Size (mm)	Measurement procedures	Goal
1	Largest-sized fragment	>50	(1) Count the number of fragments; (2) Measure the three-dimensional size of fragments with a Vernier caliper; (3) Weigh the fragments with an electronic balance	(1) Number of fragments; (2) Size feature; (3) Mass distribution
2	Large-sized fragment	30～50
3	Medium-sized fragment	20～30
4	Medium and small-sized fragment	10～20
5	Small-sized fragment	4.75～10
6	Large-sized particle	2～4.75	Weigh with an electronic balance	Total mass
7	Medium-sized particle	1.18～2
8	Fine-sized particle	0.6～1.18
9	Microsized particle	<0.6
