Abstract
The full-scale International Standards Organization (ISO) 9705 Room/Corner Test is currently used to regulate compartment-lining materials in the High Speed Craft (HSC) Code. This test method involves the use of large amounts of material so that the test method is an impediment in developing new materials. Bench-scale tests like the Cone Calorimeter and the Lateral Ignition Flame Test (LIFT) Apparatus may provide indications of full-scale performance in the IS0 9705. The objective of this work is to assess if correlations and mathematical models based on bench-scale data can predict material performance in the IS0 9705 Test. The results of this project show that it is possible to learn a great deal about the expected performance of materials in the IS0 9705 Test from bench-scale tests like the Cone Calorimeter and the LIFT Apparatus. Both the simple correlations using the Flammability Parameter deduced from the Cone Calorimeter and the mathematical models using Cone Calorimeter and LIFT data provided clear insights into the burning behavior of materials in the IS0 9705 Test. The Flammability Parameter deduced from Cone Calorimeter data was able to correlate the heat release rate and time to flashover in the IS0 9705 Test. This provides the opportunity to obtain significant information concerning expected IS0 9705 performance from a few tests of small samples. It is significant that LIFT results are not required to allow correlation of the performance of U.S. Coast Guard (USCG) HSC Materials. The mathematical models performed well in predicting the heat release rate and time to flashover in the IS0 9705 Test. These more sophisticated methods provide additional confidence in the ability of bench-scale tests to be used to predict the performance of materials in the IS0 9705 Test. Further, these models have the potential to allow prediction of realistic scenarios, which differ from the ISO 9705 test method. Neither correlations from the Cone Calorimeter nor the mathematical models adequately predict the smoke generation rates in the ISO 9705 Test. The inability to predict smoke generation is particularly significant for materials that pass the heat release rate criteria in ISO 9705. Significant additional work is needed in this area. Volume 1 of this report contains the objectives, approach, test results, and conclusions. Volume 2 consists of three appendices; a) prediction based on Quintiere's model; b) evaluation of Worcester Polytechnic Institute (WPI) zone model, and c) Hughes Associates/U.S. Navy Corner Flame Spread model and comparison with USCG ISO 9705 Test results.
