This standard encompasses a test method for measuring the contribution of climate control, heating, and ventilation systems operated under specific environmental conditions to the temperature and humidity of the operator environment for tractors and self-propelled machinery used in agriculture and forestry. Due to the influence of heat load from external sources (e.g., solar heating), the method may not fully determine the climate conditions of the environment where the operator is situated.

EN 14269-5

This standard aims to pressurize the interior of the operator cabin for tractors and self-propelled machinery used in agriculture and forestry. The objective of this test is to increase the pressure within the operator compartment of tractors and self-propelled machinery. The pressurization system within the operator compartment is utilized. The pressurization system must be entirely powered by standard equipment in the motor-driven test machine operated at the declared speed.
