ASTM E145-19 applies to the design and performance requirements of gravity convection and forced ventilated ovens. The standard specifies common performance metrics for ovens in laboratory and industrial environments, including key parameters such as Temperature uniformity, time constants, and ventilated rates. The standard defines four oven types (Type IA, IB, IIA, IIB) in detail, with specific requirements for their Temperature range, control accuracy, and Stability. Gravity convection ovens are suitable for the Temperature range of 20 ° C to 200 ° C, while forced ventilated ovens are suitable for the Temperature range of 20 ° C to 500 ° C. Temperature uniformity testing methods are also provided, such as measurement using nine calibrated Thermocouples to ensure equipment performance meets specifications. The standard does not cover safety requirements involving flammable gases or vapors and is suitable for oven performance evaluation in general purpose test operations.
