ISO 6097:1989 PDF

Scope: This International Standard specifies a method of testing the performance of heating and ventilation. systems in closed cabs of tractors and self-propelled machines for agriculture. The method allows comparison of cab heating and ventilation systems and determination of the climate inside the cab with respect to specified requirements for temperature and air velocity. This can be achieved by two different, but equivalent, procedures : a) testing in a cold-chamber; b) testing without a cold-chamber. In the latter case, it is essential that the requirements for air velocity (see clause 5) are observed (this may be achieved, for example, by the use of fans) and that the results of the test are not influenced by ambient radiant energy (for example direct sunlight). The two basic principles of heating systems are also con- sidered : a) heating independent of the engine : in this case, the heating system is adjusted in accordance with the manufac- turer’s instructions; b) heating dependent on the engine: in this case, the heating system is tested with the engine loaded under specified conditions (see 5.4.5), corresponding approxi- mately to the engine load of a tractor with an empty trailer travelling on a road.
