The pressure standards of empty aerosol tin cans are roughly divided into: ordinary pressure, medium pressure, and high pressure.
There are also DOT pressure standards used in the United States: 2N, 2P, 2Q

Ordinary pressure:Deformation pressure ≥1.20MPa, burst pressure ≥1.40MPa

Medium pressure:Deformation pressure ≥1.60MPa, burst pressure ≥1.80MPa

High pressure:Deformation pressure ≥1.80MPa, burst pressure ≥2.00MPa

2Npressure:Deformation pressure ≥1.00MPa, burst pressure ≥1.45MPa

2P pressure:Deformation pressure ≥1.10MPa, burst pressure ≥1.65MPa

2Q pressure:Deformation pressure ≥1.24MPa, burst pressure ≥1.86MPa
