The concept
The specification of forced circulation wind furnace, оцена отпорности на топлоту за електричне изолационе материјале. The oven shall be classified according to the ventilation way: type I and type II. Ventilation rate, set temperature, temperature change, and thermal log time characteristics should be determined using the specified test method.

Обим
1.1 This specification covers mandatory convection wind power heating furnaces that can operate in all or part of a temperature range from 20°C to 500°C above ambient temperature and is used for heat resistance assessment of electrical insulation materials.

1.2 The specification requirements for Type I ovens are based on and technically identical to IEC Publication 60216-4-1. The requirement of type II oven with D2436 specification requirements are basically the same. This specification and the associated test method D5374 have replaced specification D2436.

1.3 Although the ovens covered by this specification are primarily used for thermal durability assessment, their characteristics make them suitable for other applicable applications.

1.4 Values expressed in SI units should be considered standard values. This standard does not include other units.

1.5 Овај стандард није намењен решавању свих безбедносних питања, ако их има, повезана са његовом употребом. Одговорност корисника овог стандарда је да успостави одговарајућу безбедност, здравствене и еколошке праксе и да се утврди применљивост регулаторних ограничења пре употребе.

1.6 this international standard is the technical barriers to trade, according to the world trade organization committee issued “about setting international standards, guidelines and recommendations of the decision of the principle of” the establishment of the internationally recognized principles of standardization.
