3. Chemical Safety Testing (Part 3)
3.1 Heavy Metal Migration Testing
3.2 Specific Chemical Substance Restrictions
3.3 Food Sanitation Act Related Testing
1. Mechanical and Physical Properties Testing (Part 1)
Small parts testing, edge and point sharpness, moving parts clearance, projectile kinetic energy, cord length restrictions, sound level testing, stability and strength testing. Test methods are essentially consistent with EN 71-1 and ISO 8124-1.
The above Food Sanitation Act tests use water (40 °C, 30 minutes) or 4 %% acetic acid as extraction solution.
