completely detonate after immersion in not less than 12 inches of water for not less than 72
hours.
3.9 Solar radiation (applicable to Type I and II). The detonating cord shall show no
change in physical characteristics such as form, color, and diameter after exposure to 130°
± 5°F with 360 ± 47 Btu/ft2/hr simulated solar radiation for a minimum of 4 hours.
