- Laser classification (1, 1M, 2, 2M, 3R, 3B, 4)
- Accessible emission limits
- Protective housing, interlocks
- Labeling compliance
Packaging & Shelf Life Testing
- ISO 11607-1, -2: Sterile barrier packaging
- ISO 11135: EO sterilization validation
- ASTM D4169: Distribution simulation
- ASTM F1980: Accelerated aging
