Implementation recommendations

Detection system configuration

• UV light source needs to be calibrated regularly to ensure the wavelength is 365nm
• Ambient light control ≤21.5 lux (2 foot candles)
• It is recommended to use AMS2641 standard oil-based carrier

Safety precautions

This standard does not cover the toxicity protection requirements for fluorescent magnetic particles. It is recommended that:

1. Organic vapor protection equipment should be used
2. Forced ventilation should be implemented in the testing area
3. Waste should be treated as hazardous chemicals
