ED Decision 2003/18/RM
A minimum of three specimens must be tested and the results averaged. For fabrics, the direction of weave corresponding to the most critical flammability conditions must be parallel to the longest dimension. Each specimen must be supported vertically. The specimen must be exposed to a Bunsen or Tirrill burner with a nominal 9.5 mm (0.375 inch) I.D. tube adjusted to give a flame of 38.1 mm (14 inches) in height. The minimum flame temperature measured by a calibrated thermocouple pyrometer in the centre of the flame must be 843°C (1550°F). The lower edge of the specimen must be 19 mm (0.75 inch) above the top edge of the. burner. The flame must be applied to the centre-line of the lower edge of the specimen. The flame must be applied for 60 seconds and then removed. Flame time, burn length, and flaming time of drippings, if any, must be recorded. The burn length determined in accordance with paragraph F5 of this Appendix must be measured to the nearest 2.5 mm (0.1 inch).
