1.1 ,This specification covers the performance requirements for general-purpose air ovens ordinarily used in testing operations, which have a testing chamber up to 0.6 m3 (25 ft3) in volume. It is applicable to gravity-convection ovens designed to operate over all or part of the temperature range from 20 ,°,C above ambient temperature to 200 ,°,C and to forced-ventilation ovens designed to operate over all or part of the temperature range from 20 ,°,C above ambient temperature to 500 ,°,C.
Note 1: ,Ovens are designed for maximum operating temperatures of about 200 ,°,C, 300 ,°,C, and 500 ,°,C, the thermal insulation and cost of the oven being dependent on the maximum temperature required.
