1.1This 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.

1.2It is applicable to gravity convection ovens designed to operate over all or part of the temperature range from 20°C above ambient room temperature to 200°C.

1.3It is applicable to forced ventilation ovens designed to operate over all or part of the temperature range from 20°C above ambient room temperature to 500°C.

1.4This specification does not include safety requirements that are essential for ovens used in the presence of combustible materials.

1.5The values stated in SI units are to be regarded as the standard. The values given in parentheses are for reference only and may be approximate.

1.6Calibration ovens to this standard are necessary to assure their operative performance under typical conditions of use and shall be performed periodically, either according to the manufacturer’s recommendations, the quality requirements of the end user, their customers, or suppliers.

1.7This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
