description abstract	This standard shall apply to ovens and furnaces operating above ambient temperatures to over 5000 °F (2760 °C) and at pressures normally below atmospheric to 10(-8) torr (1.33 × 10(-6) Pa). (Footnote )Types of Furnaces. The user's requirements for vacuum processing shall determine the type of furnace walls, the size of the furnace, the special atmospheres required, or the reduction from normal atmosphere down to a special vacuum of 10(-8) torr (1.33 × 10(-6) Pa). Purpose. Because the heat processing of materials can involve a serious fire and explosion hazard that can endanger the furnace and the building in which the process is located and possibly the lives of employees, adequate safeguards shall be provided as appropriate for the location, equipment, and operation of such furnaces. Footnote - NOTICE: An asterisk (*) following the number or letter designating a paragraph indicates that explanatory material on the paragraph can be found in Appendix A.
