The following IBCs are authorized: (a) Metal: 31A, 31B and 31N; (b) Rigid plastics: 31H1 and 31H2; (c) Composites: 31HZ1. Only liquids with a vapour pressure less than or equal to 110 kPa at 50 °C, or 130 kPa at 55 °C, are authorized in IBCs. …

Ammonia solutions may be transported in rigid or composite plastic IBCs (31H1, 31H2 and 31HZ1) that have successfully passed, without leakage or permanent deformation, the hydrostatic test specified in §178.814 of this subchapter at a test pressure that is not less than 1.5 times the vapor pressure of the contents at 55 °C (131 °F).

The current requirements in 6.5.6.8.4.2 regarding the hydraulic pressure test for commonly used composite IBCs (31H1, 31H2, 31HZ1, 31HZ2) define a test pressure equal to the substance vapour pressure taken at a reference temperature of 50°C or 55°C and multiplied by a safety factor of 1.75 or 1.5 respectively or twice the static pressure of ...

Many years now there is consensus among most experts involved in fire protection that a fire in warehouses storing flammable and combustible liquids in composite IBCs are difficult to control and extinguish. Tests with IBCs show that they fail in just over 1 minute to 11 minutes when exposes to a fire.
