ASTM D5374-22 PDF Download

The ASTM D5374-22 standard provides procedures for evaluating the characteristics of forced-convection laboratory ovens that are used for the thermal endurance evaluation of electrical insulation materials. These ovens are operated at temperatures ranging from 20°C above the ambient temperature to 500°C.

The standard is based on the IEC Publication 60216-4-1 and is technically identical to it. This means that the test methods outlined in ASTM D5374-22 are consistent with the international standards set by the IEC.

It is worth noting that this standard and the associated specification, D5423, have replaced the previous Specification D2436. This indicates that the ASTM D5374-22 standard is an updated version of the older specification, aligning with current industry practices and advancements in laboratory testing for electrical insulation materials.
