This British Standard describes a method of estimating the concentration of disinfectant which may be recommended for environmental disinfection in hospitals under \'dirty\' conditions.
NOTE1. The overall result is determined using information obtained for contact times of 8min and 18min only. The method described in this standard makes reference also to a contact time of 28min and the procedure relating to this contact time may be omitted. However operators often find it useful to apply the method as described especially if the recommended concentration of the disinfectant under test is unknown.
NOTE2. The titles of the publications referred to in this standard are listed on the inside back cover.
