NFPA 86D provides requirements for safeguarding against fire and explosion hazards in Class D furnaces that operate at above ambient temperatures to over 5000 degrees F (2760 degrees C), and at pressures normally below atmospheric to 10(to the minus 8) torr (1.33 x 10(to the minus 6) Pa). It includes the many common safety requirements covered by NFPA 86D, such as for location, construction, heating system, safety equipment, testing, maintenance and fire protection. This important document also covers the more unique features associated with vacuum furnaces.
