摘要：	This report describes testing of an ignitability standard for bedding aboard commercial vessels as proposed at the International Maritime Organization (IMO). The objectives were to identify weaknesses, to qualitatively gauge the effectiveness of the standard, and to evaluate performance of domestic products. A version of the proposed standard was adopted as MO Resolution A.688(17), Fire Test Procedures for Ignitability of Bedding Components. The adopted version of the standard is only addressed in this report with regard to the pass/fail criteria. The proposed standard had three ignition sources: (1) cigarette covered by a cotton sheet, (2) cigarette covered by a cotton wool pad, and (3) a match flame (6.5 mm tube burner). The cotton wool pad and cotton sheet were 150 mm square. Test samples were made by cutting mattresses, blankets, and sheets into 450 mm by 350 mm sections; pillows were tested whole. The duration of the exposure to the ignition source is complete consumption of the cigarette and 20 seconds for the flame. The sample is considered to fail if it demonstrates progressive smoldering or flaming ignition. Progressive smoldering covers several responses including length of char. The proposed test method was followed with minor exceptions of washing the samples and using longer cigarettes. The bedding components were nine inner spring mattresses, four pillows, one pillow case, five sheets, and two synthetic blankets. The results of the testing are presented in five sections. The first section addresses how U.S. materials fared under the proposed test protocol. The second section addresses the effect of washing the sheets. The third section presents the results of testing combinations of bedding components. The fourth section addresses the appropriateness of the cotton-wool pad as a cover for the cigarette. The fifth section addresses the appropriateness of mineral wool as a substrate.
