Latest Edition of ‘NFPA Standards’ Includes Many Changes to Examine

NFPA 86, Standard for Ovens and Furnaces, was first issued in its current form in 1985. It has been updated regularly every four years by the Technical Committee on Ovens and Furnaces.

The 2015 edition of NFPA 86 has also been prepared and updated by the Committee. It was issued by the Standards Council on April 29, 2014, and was put into effect on May 19.

In our future blog posts, Industrial Furnace Service Hub (IFSH) will identify and examine each of these individual changes, as we seek to be in complete compliance and also assist furnace concerns with their understanding of the changes to codes and requirements – ultimately improving safety and operation within the industrial furnace industry!

According to the introduction to the 2015 edition of NFPA 86:

  • It includes several changes to Chapter 3 due to the addition of definitions for burner management system, flame failure response time, flame detector, hardwired, combustion safeguard and pressure regulator types.
  • The committee also deleted requirements from Chapter 12 applicable to arc melting furnaces (or electric arc furnaces) as the provisions have not been maintained the committee no longer has the relevant expertise.
  • The committee added procedures for placing equipment into service based on purging practices in NFPA 54 and NFPA 56. Committee modified the standard to clarify the types of acceptable devices used for combustion safety service.
  • The committee added a requirement prohibiting manifolding vent lines from different pressure levels.
  • As a result of introducing definitions for burner management system and combustion safeguard, the committee modified requirements in Chapter 8 for logic systems for both BMS logic and programmable logic controller (PLC) systems. The committee modified requirements for Class A and Class C ovens and furnaces, including the development of new requirements on fire protection and safety ventilation for Class A ovens.
