The concept
The specification of forced circulation wind furnace, Hitzebeständigkeitsbewertung für elektrische Isoliermaterialien. 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.

Geltungsbereich
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 In SI-Einheiten ausgedrückte Werte sollten als Standardwerte betrachtet werden. This standard does not include other units.

1.5 Diese Norm soll nicht alle Sicherheitsprobleme behandeln, wenn überhaupt, mit seiner Verwendung verbunden. Es liegt in der Verantwortung des Anwenders dieser Norm, für angemessene Sicherheit zu sorgen, Gesundheits- und Umweltpraktiken zu prüfen und vor der Verwendung die Anwendbarkeit behördlicher Beschränkungen zu ermitteln.

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.
