In 5.2.7, the base plus fog density has been reviewed and a maximum level has been set for the point of manufacture. to use in order to set the expiry date of the product. In 7.3, in recognition that background radiation can reduce the expiry date of a film, information to this effect has been included. In Table 1, the requirements for C speed film have been removed, as use of this film is no longer justified on radiological and clinical grounds. In 7.2, the requirements for film sizes have been rationalized to conform with current manufacturing practice In 7.1, no requirement for a colour coding system for films has been included; instead it is the responsibility of the manufacturer to provide a clear explanation in the instructions if a colour coding system is used. In 7.1, films requiring the use of an external attenuation device have been included. ii license from IHS Not for Resale
