Atmospheric factor fa Clause Samples
The 'Atmospheric factor fa' clause defines how atmospheric conditions are quantified and factored into a contract or agreement. Typically, this clause specifies the method for measuring relevant atmospheric variables—such as temperature, humidity, or air pressure—and outlines how these measurements impact obligations, performance standards, or risk allocation between parties. By establishing a clear metric for atmospheric influences, the clause helps ensure that both parties understand how weather or environmental conditions may affect the execution of contractual duties, thereby reducing disputes related to unforeseen atmospheric changes.

Atmospheric factor fa. This factor indicates the effects of environmental conditions (pressure, temperature and humidity) on the air drawn in by the engine. The atmospheric factor formula differs according to the type of engine.

5.4.2.1.1. Naturally aspirated and mechanically pressure charged engines 99 T 0.7 fa = p * 298 s
5.4.2.1.2. Turbocharged engines with or without charge air cooling 99 0.7 T 1.5 fa = p * 298 s 1 The tests may be carried out in air-conditioned test rooms where the atmospheric conditions may be controlled. In the case of engines fitted with automatic air temperature control, if the device is such that at full load at 25 °C no heated air is added, the test shall be carried out with the device fully closed. If the device is still operating at 25 °C then the test is made with the device operating normally and the exponent of the temperature term in the correction factor shall be taken as zero (no temperature correction).
