ABSTRACT: The author’s development of an alternative design for a fireworks mortar coincided with the restructure of regulations concerning display fireworks in the State of Queensland, Australia. This new Code of Practice for the Display of Outdoor Fireworks has a requirement for manufacturers of equipment to develop performancebased tests that will prove the safety and suitability of plant and equipment used. The authorities proposed that a mortar tube was to be given a service life of five years. This article describes a protocol that has been successfully put into practice to test the new mortar tube. The protocol is called the Five Year Accelerated Test Program or “FYATP”.
Keywords: mortar, plastic tube, service life, polyethylene
