Division 3.3 Ambient conditions

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

1. 3.3.1.

   Atmospheric pressure shall be equal or greater than 82,5 kPa;

2. 3.3.2.

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

   T = – 0,4514 * (101,3 – p_b) + 311

   where:

   • T is the ambient air temperature, K,

   • p_b is the atmospheric pressure, kPa.
