note : 1) Operating conditions : Cooling water / LLC 50%, Thermostat / jacked open.
2) The above judgment (evaluation) standards is to be applied in the max. ambient condition of 40°C (104°F), in case
that the ambient temperature is over 40°C (104°F), it must be judged adding the balance between the actual
temperature and 40°C (104°F) to the judgment standard.
3) Do not run a cooling test if the ambient temperature is below 24°C (75°F) because the large change in air density
and radiation from non cooling system parts give false results.
***Air To Boil (ATB) value must be calculated by using below max. temperature :
LLC 50% with 88.3 kPa (0.9 kgf/cm
special note :
1) The judgment standard > 49°C (120°F) in the above formula { ***ATB = (x) - (CWIT) + (AT) } is KUBOTA's standard.
It may change depending on applications, countries, locations, etc.,
therefor, it is better to judge under the discussion with OEM's referring their own experienced values.
