In the North American construction market, the most widely cited fire test for qualifying material for use as interior and exterior finish material is based on the ASTM E-84 tunnel test. This test was developed in the late 1940s. There is quite a variation in the test results when running a composite panel. A study was done to determine the effect of glass content and panel thickness on the flame spread and smoke index. Another study was also conducted to determine how glass content affects the results of ASTM E1354 Cone Calorimeter Test. It was found that the sample thickness of the panel had a very large effect on the smoke index. This effect is being investigated. It was also seen that glass content can have an affect on flame spread index and smoke values. Information will also be shown on the round robin tests that ASTM has performed showing the reproducibility of the test within a testing lab and between different testing labs. These results indicate that when choosing a material for an application, the thickness and glass content of the laminate needs to be considered to verify that the system will meet the required test results for the application.
