This specification covers the performance requirements for general-purpose ovens used in testing laboratories. These ovens are used for:
This is arguably the most critical metric. It measures the difference between the highest and lowest temperatures inside the oven chamber at any given time. astm e 145
The standard organizes ovens into based on their target temperature uniformity performance and mechanical design: Airflow Mechanism Temperature Uniformity Tolerance Performance Tier Type IA Gravity Convection Tight (High Precision) Precision Laboratory Grade Type IB Gravity Convection Relaxed (Standard Precision) General Purpose Utility Type IIA Forced Ventilation Ultra-Tight (Maximum Precision) High-Performance Industrial Type IIB Forced Ventilation Standard Production Testing 3.
