[0002] Protective equipment inside hazardous chemical workshops, underground projects, and explosion-proof areas must undergo resistance testing. This testing primarily focuses on ensuring the equipment remains undamaged by explosions and impacts, maintains its function under pressure, and prevents the backflow of toxic media. The testing is highly targeted. By measuring the structural integrity, material toughness, and functional retention of the equipment under different explosion intensities, distances, and shock wave types, the safety and reliability under actual use conditions are ensured. The testing covers multiple dimensions, including material mechanical properties, structural impact resistance, sealing performance, and environmental durability.
