1. Sampling: Conduct sampling mechanically or manually according to standards to ensure representativeness.

2. Sample Preparation: Crushing, splitting, and grinding to achieve the desired particle size for analysis.

3. Laboratory analysis: physical testing, chemical analysis, and hazardous substance testing.

4. Data review and reporting: Compare with ISO, GB, or trade contract limits, and issue test certificates in both Chinese and English.
