    Abstract

    This specification covers performance requirements for general purpose air ovens ordinarily used in testing operations, which have a testing chamber up to 0.6 cu. m (25 cu. ft.) in volume. It applies 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, as well as forced ventilation ovens designed to operate over all or part of the temperature range from 20°C above ambient room temperature to 500°C.

    Included in this specification are the test procedures addressing temperature uniformity and rate of ventilation.

    This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

    1. Scope

    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.

    1.2 It 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.

    1.3 It 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.

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

    1.5 The 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.

    1.5.1 The SI base unit of the expression of temperature is Kelvin (K), the unit of measure used in this specification is Celsius (°C) and has been derived mathematically.

    1.6 Calibration 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.

    1.7 This 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.
