Abstract : The AECMA working party which is drawing up a standard for the artificial weathering of aircraft transparencies has through a collaborative experimental programme shown the importance of measuring the output of ultraviolet radiation of the various lamps used in weathering chambers. A simple method of monitoring radiation below 320 nm, based on the use of polysulphone film, is described. The manufacture and properties of the film are presented along with details of its use. Variability in the output of a Xenon-arc source as a result of lamp and filter ageing is demonstrated and data on the ultraviolet intensity of different types of lamp are compared with measurements made outdoors at Dhahran, Innisfail and London.
