30、Growth2015 EditionThis edition of NFPA 286, Standard Methods of Fire Tests for Evaluating Contribution of Wall andCeiling Interior Finish to Room Fire Growth, was prepared by the Technical Committee on FireTests. It was issued by the Standards Council on November 11, 2014, with an effective date ofD
31、ecember 1, 2014, and supersedes all previous editions.This edition of NFPA 286 was approved as an American National Standard on December 1,2014.Origin and Development of NFPA 286The 2000 edition was the first edition of this standard. This document was developed inresponse to activities associated w
32、ith the regulation of interior finishes in NFPA 101, Life SafetyCode. The Fire Safety Technical Committee on Furnishings and Contents had proposed modi-fications to NFPA 265, Standard Methods of Fire Tests for Evaluating Room Fire Growth Contributionof Textile Wall Coverings, for the 1997 edition of
33、 NFPA 101. These modifications would haveestablished a test protocol that was not appropriate to the scope of NFPA 265. NFPA 286addresses those concerns associated with interior finishes that do not remain in place duringtesting to NFPA 265 test protocols.The 2006 edition included a complete editori
34、al rewrite for compliance with the Manual ofStyle for NFPA Technical Committee Documents. Further organizational and editorial changes weremade to improve the application of the test method, particularly with regard to the testprocedure. The purpose of the document was revised to clarify the documen
35、ts intent. Tech-nical changes addressed recording and documentation of the fire test.The 2011 edition expanded the scope of the document to include provisions for all walland ceiling interior finish. A new annex section addressing acceptance criteria was added.The 2015 edition includes a new section
