Division 4.2 Ambient conditions

The test shall be conducted under ambient conditions meeting the following conditions:

Atmospheric pressure greater than or equal to 82,5 kPa,

Temperature greater than or equal to 266 K (– 7 °C) and less than or equal to the temperature determined by the following equation at the specified atmospheric pressure:

T = – 0,4514 × (101,3 – pb) + 311

where:

• T is the ambient air temperature, K

• pb is the atmospheric pressure, kPa
