UL 2360-2000 pdf free download.Test Methods for Determining the Combustibility Characteristics of Plastics Used in Semi-Conductor Tool Construction. 3 General 3.1 The plastic material covered by this standard shall be subjected to: a) Four cone calorimeter ignition response tests, see 4.1 ; b) Three cone calorimeter combustibility tests, see 4.2; and c) Three large scale parallel panel tests, see Parallel Panel Test, Section 5. When the average flame propagation index is less than 6, as determined by the cone calorimeter tests,then the large scale parallel panel test is not required to be conducted. 3.2 When the Cone Calorimeter Tests, Section 4, and the Parallel Panel Test, Section 5, indicate different performance classifications, then the parallel panel test results shall be utilized in determining the classification of the plastic material tested. 4 Cone Calorimeter Tests 4.1 Cone calorimeter ignition response test 4.1 .1 Four cone calorimeter ignition response tests are to be conducted in accordance with ASTM E1 35497 a using a sample size of 3.9 by 3.9 inches (1 00 mm by 1 00 mm) with a thickness representative of the final product, up to 2 inches (50 mm) thick. a ASTM E1 354-97 – Standard Test Method for Heat and Visible Smoke Release Rates for Materials and Products Using an Oxygen Consumption Calorimeter, American Society for Testing and Materials, Phildelphia, PA. 4.1 .2 The cone calorimeter ignition response tests are to be conducted using the following conditions: a) Horizontal orientation of samples; b) Samples tested using an edge frame sample holder, and c) The test conducted with a radiant heat flux setting of 20, 35, 50 and 75 kW/m 2 . The cone calorimeter ignition response tests are terminated when sustained ignition has occurred. When ignition does not occur at values below 75kW/m 2 , then intermediate radiant heat flux values shall be selected so that at least four cone calorimeter ignition response tests have flame ignition test results. See 4.3 for test calculations. 4.2 Cone calorimeter combustibility tests 4.2.1 Three cone calorimeter combustibilty tests are to be conducted in accordance with ASTM E1 35497 b using a sample size of 3.9 by 3.9 inches (1 00 mm by 1 00 mm) with a thickness representative of the final product, up tro 2 inches (50 mm) thick. b ASTM E1 354-97 Standard Test Method for Heat and Visible Smoke Release Rates for Materials and Products Using an Oxygen Consumption...
