Abstract
The test procedure covered by this standard was developed prior to 1920 by Underwriters Laboratories Inc. The test procedure was put in standard form by the E5 Committee on Fire Standards of the American Society for Testing and Materials, adopted by ASTM as a tentative standard in 1955, and revised in 1956. It was adopted by the NFPA on May 22, 1958, on recommendation of the Committee on Fire Tests and was subsequently published as NFPA 256, in May 1958. It was adopted by ASTM as a standard later in 1958 and publihsed by ASTM as E 108-58. It was also published by Underwriters Laboratories Inc., as No. 790, September 1958. Revised NFPA editions were published in 1964, 1970, 1976, 1981, and 1987. The 1993 edition of NFPA 256 was revised editorially to bring this document into conformance with its ASTM and UL counterparts. The 1998 edition adds a new chapter 13, "Report of Results." This was done to clarify and to identify the required elements that relate to both specimen preparation and test results.
