Hot wire tester 15014035973 Glowing / hot wire flammability test methods - Glow finished wire based test methods (IEC 60695-2-11: 2000 / GB / T5169.11-2006) glow-wire flammability test method for materials (IEC 60695 -2-12: flammable glow wire test methods 2000 / GB / T5169.12-2006) starting materials (IEC 60695-2-13: 2000 / GB / T 5169.13-2006) Terms and Definitions glow-wire flammability index GWFI GWFI - glow-wire flammabilityindex a specified thickness of the test sample in three consecutive trials highest test temperature shall meet one of the following conditions: a) within 30 seconds after removal of the glow wire test extinguish flames or burning of the sample, and placed in a test sample following packaging tissue paper no ignition; b) there is no ignition test sample. Glow-wire ignitability temperature GWIT GWIT - glow-wire ignitiontemperature than the "three consecutive tests will not cause a predetermined thickness test samples from the top of the glow-wire ignition temperature of the highest high 25K (between 900 ℃ ~ 960 ℃ high 30K)" temperature. Sample requirements Materials Laboratory test sample requirements are as follows: Sample sample should be large enough portion of the fixed-size plane, when tested in the test plane remains in a vertical position. Test samples can be made in several ways: compression molding, injection molding or casting, or finished parts from sheet metal, which are large enough to cut from the plane. Dimension plane portion should be: length: ≥60mm, width (jig inner): ≥60mm assess flammability usually requires a set number of 10 test samples in accordance with the requirements of this test. Severities 1. Glow Wire Flammability Index (GWFI) should be selected following the test temperature test temperature / ℃: 550/600/650/700/750/800/850/900/960 2. Glow-wire ignitability temperature (GWIT ) should be selected following the test temperature test temperature / ℃: 500/550/600/650/700/750/800/850/900/960 Evaluation of test results 1. Glow Wire Flammability Index (GWFI) assessment of the results if the test sample no ignition or satisfy the following two conditions is considered withstood this test a) If the test sample b extinguished flames or burning hot in the 30s after the glow wire removed) packaging tissue paper no ignition if the above is not satisfied one of two or conditions are selected from a lower test temperature, the test sample with a new test is repeated. If these two conditions are satisfied, then choose a higher test temperature, sample test is repeated with a new test. Under test shall be repeated in the test sample meets the conditions a) and b) the maximum test temperature. To determine the maximum test temperature is in three consecutive trials GWFI satisfy conditions a) and b). 2. Evaluation of the glow-wire ignitability temperature (GWIT) results should be applied to determine the ignition temperature of the sample during the glow wire test, than three consecutive trials were not caused by the maximum temperature at the top of the glow-wire ignition test samples of high 25K (900 ℃ between 960 ℃ for 30K) test temperatures recorded as GWIT.
