Test duration.

An important note: extinguishers must be left for (24) hours before performing tests in order to equalize temperature.

1. Hydrostatic pressure (test pressure and burst pressure).

Duration of this test is one hour.

2. Marking.

Check that the extinguisher's color is red regardless of it's classification.
