3 Terms and Definitions
For the purposes of this standard, the following terms and definitions apply.
3.1 Explosive substance
Substance that could have violent chemical reaction with external actions (such as heating and impact), generate a large amount of gases and heat in a second and make urgent rise of ambient pressure leading to explosion and damaging the ambient environment. In this standard, explosive substance refers to the one specified in GB 12268, exclusive of civil blasting material.
3.2 Chemical toxic substance
Chemicals with extreme acute toxic hazards, including artificially synthesized chemicals and their mixture (including pesticide) and natural toxin. In this standard, chemical toxic substance refers to the one listed in "List of Acute Toxic Chemicals" of State Administration of Quality and Technical Supervision (SAQTS) Announcement.
3.3 Actual capacity of tank
In normal temperature, the water capacity of that fills up the tank.
