| Abstract: | An investigation of cone calorimeter test procedures was performed using two types of mattress composites with various specimen preparations and equipment configurations. The objective was to discover suitable procedures for testing mattress composites. Concurrent with this work a much larger and more sophisticated project known as CBUF was underway in Europe. One of CBUF's secondary objectives was to provide an appropriate test protocol for testing upholstered furniture composites, including mattresses. Most of the CBUF protocol was available at the time of this study and a modified form of the specimen preparation technique was used in this investigation. Preliminary tests found unacceptable test performance with some configurations. Subsequent testing examined variations of the established test protocols and other test procedures. The data sample was small, but observations of the data indicate trends that might be attributable to the use of the different procedures. Significantly it was determined that the edge frame used to hold specimens in place during the test does affect the test results. A modified CBUF protocol proved to be the best procedure, but it requires extensive experience with the CBUF specimen preparation method in order to be able to produce satisfactory specimens. © 1997 by John Wiley & Sons, Ltd. |
