Fire Testing - Moulded uPVC
To determine the performance of a material when it is subjected to the conditions of the test specified in BSEN60695-2-11 / IEC60695-2 11:2000, Fire Hazard Testing Part 2-11: Glowing / Hot- Wire Based Test Methods - Glow-Wire Flammability Test Methods for End- Products utilising the test procedure specified in Clause 8 of BEEN60695-2-10:2001 and Clause 10 of BSEN60695-2-11:2001 / IEC60695-2-11:2000. Purpose of Test Prior to the test, the specimens were conditioned for a minimum period of 24 hours in an atmosphere having a temperature between 15°C and 35°C and a relative humidity of between 45% and 75%. Conditions of Specimens
In accordancewith the standard, wrapping tissuews placed 200mmbelow thepoint of glow-wire application. A total of three specimens were tested at each temperature and the following observations were recorded: Test Results

ti = The duration from the beginning of tip application up to the time at which the specimen or the layer placed below it ignites. te = The duration from the beginning of tip application up to the time when flames extinguish during or after the period of application ta = The duration of tip application
Therefore, the results obtained demonstrate that the product, as tested, satisfactorily withstood the glow- wire test at a temperature of 650°C, with an application period of 30 Evaluation
