Characterization of the Burning Behaviour of Plastics by a New Method

A method is described, that allows a quick and simple testing of the burning behaviour of plastics. It takes into account ignition time as well as afterflame time; properties that are characteristic for the burning behaviour of a particular plas-tic material. The procedure is easy to perform, it does neither require injection-moulded samples nor expensive equip-ment. The method provides a classification of the burning behaviour. It is especially suitable for a screening of plastic materials complementing established methods like UL-94, GWFI and LOI, and may find application in the development of flame retardants
