    1、86 NFPA Standard for Ovens and Furnaces 2019IMPORTANT NOTICES AND DISCLAIMERS CONCERNING NFPA STANDARDS NOTICE AND DISCLAIMER OF LIABILITY CONCERNING THE USE OF NFPA STANDARDS NFPA codes, standards, recommended practices, and guides (“NFPA Standards”), of which the document contained herein is one,

    2、are developed through a consensus standards development process approved by the American National Standards Institute. This process brings together volunteers representing varied viewpoints and interests to achieve consensus on re and other safety issues. While the NFPA administers the process and e

    3、stablishes rules to promote fairness in the development of consensus, it does not independently test, evaluate, or verify the accuracy of any information or the soundness of any judgments contained in NFPA Standards. The NFPA disclaims liability for any personal injury, property, or other damages of

    4、 any nature whatsoever, whether special, indirect, consequential or compensatory, directly or indirectly resulting from the publication, use of, or reliance on NFPA Standards.

NFPA 86 Standard for Ovens and Furnaces 2019 Edition This edition of NFPA 86, Standard for Ovens and Furnaces,

    32、 was prepared by the Technical Committee on Ovens and Furnaces. It was issued by the Standards Council on May 4, 2018, with an effective date of May 24, 2018, and supersedes all previous editions. This edition of NFPA 86 was approved as an American National Standard on May 24, 2018. Origin and Devel

    33、opment of NFPA 86 The history of the NFPA standards for ovens and furnaces goes back to NBFU 34, Regulations of the Board of Fire Underwriters for Finishing Processes (other than paint spraying) Dip Tanks, Hardening and Tempering Tanks, Flow Coat Work, Japanning and Enameling Including Ovens as Reco

    34、mmended by the National Fire Protection Association, issued in 1926. Subsequently, the ovens part of NBFU 34 was separated and issued as NBFU 86, Regulations of the National Board of Fire Underwriters for Ovens For Japan, Enamel, and Other Flammable Finishes as Recommended by the National Fire Prote

    35、ction Association, in 1931. In 1948, NBFU 86 became NFPA 86-T, Tentative Standards for Class A Oven Design, Location and Equipment. The document was issued as a standard in 1950 and titled NFPA 86, Standards for Class A Ovens and Furnace Design, Location and Equipment. The 1985 edition of NFPA 86 wa

    36、s the rst edition of the standard in its current form. It was created from the combination of the former NFPA 86A, Standard for Ovens and Furnaces Design, Location and Equipment, and NFPA 86B, Standard for Industrial Furnaces Design, Location and Equipment. The committee introduced changes in the de

    37、nitions of Class A and Class B ovens, which were published in the 1982 edition of NFPA 86B and added as a tentative interim amendment in 1983 to the 1977 edition of NFPA 86A. The changes in the denitions eliminated the principal differences between the two standards, except for the ventilation requi

    38、rements in NFPA 86A. By providing a separate chapter for ventilation requirements in the 1985 edition (Chapter 5), the committee found it was no longer necessary or desirable to maintain two separate documents that addressed the same subjects. Changes that were incorporated into the 1985 edition inc

    39、luded the following: (1) A new chapter dealing with low-oxygen atmosphere ovens was added. (2) The denitions of subjects in the text were updated and new denitions provided. (3) The text was rened in an effort to make the document more understandable. (4) The material was rearranged to comply with t

    40、he NFPA Manual of Style. The 1995 edition of NFPA 86 correlated with NFPA 86C, Standard for Industrial Furnaces Using a Special Processing Atmosphere, and NFPA 86D, Standard for Industrial Furnaces Using Vacuum as an Atmosphere. Revisions also rened and updated the standard to more current technolog

    41、ies, provided increased requirements in several areas, and expanded the explanatory material in the appendices. The 1999 edition of NFPA 86 included changes to the technical requirements in several areas and many renements that claried the technical requirements. Changes were also provided to more c

    42、learly distinguish mandatory requirements from nonmandatory recommendations and explanatory material. Nonmandatory notes were relocated to the appendices. The 2003 edition of NFPA 86 was a complete revision that incorporated NFPA 86C, Standard for Industrial Furnaces Using a Special Processing Atmos

    43、phere, and NFPA 86D, Standard for Industrial Furnaces Using Vacuum as an Atmosphere. This new, combined document provided one standard for ovens and furnaces of all types. Also, in accordance with the Manual of Style for NFPA Technical Committee Documents, referenced publications were listed in Chap

    44、ter 2 and all denitions moved to Chapter 3.OVENS AND FURNACES 86-2 2019 Edition The 2007 edition of NFPA 86 continued to bring the standard into compliance with the Manual of Style for NFPA Technical Committee Documents and to update requirements. Requirements for logic systems and programmable logi

    45、c controllerbased systems replaced the requirement that programmable logic controllers be listed specically for combustion safety service, since listed controllers were no longer available. Unenforceable text was (1) revised to be enforceable, (2) deleted, or (3) relocated to Annex A. Where appropri

    46、ate, repetitive text was replaced by tables. The former Chapter 14, Inspection, Testing, and Maintenance, was renumbered and renamed as Chapter 7, Commissioning, Operations, Maintenance, Inspection, and Testing. Requirements for operations and maintenance throughout the standard were then relocated

    47、to that chapter. In the 2011 edition, the scope of NFPA 86 was claried to exclude uid heaters, and reference was made to the new NFPA 87, Recommended Practice for Fluid Heaters. All requirements for re protection were relocated to Chapter 9. Chapter 13, which covers Class C furnaces, was revised to

    48、clarify the requirements for the introduction and removal of special atmospheres. The requirements for repeated preignition purge were revised to recognize the unique characteristics of ovens using pulse ring of burners. In addition, the requirements were claried for safety shutoff valves that must

    49、close when a burner experiences a loss of ame signal. The 2015 edition of NFPA 86 includes several changes to Chapter 3 due to the addition of denitions for burner management system, ame failure response time, ame detector, hardwired, combustion safeguard, and types of pressure regulators. The committee also deleted requirements from Chapter 12 applicable to arc melting furnaces (or electric arc furnaces) because the provisions have not been maintained and the committee no longer has the relevant expertise. The committee added procedur
