An Available Superseded Standard is one, which has been made available for a period of time although it has been formally superseded by another Standard. Its availability is maintained where it is referenced in legislation/regulations or in other Standards and its use should be restricted to where so referenced. No responsibility is taken by Intertek Inform as to the ongoing technical validity of such a Standard, the responsibility resting with the referencing authority.

This Standard sets out a method for determining the most probable number (MPN) of spores of sulfite-reducing anaerobes (clostridia) including C.perfringens in water, using a multiple tube dilution technique, with a confirmation procedure for identifying C.perfringens.

This Standard sets out a method for determining the most probable number (MPN) of sporesof sulfite-reducing anaerobes (clostridia) including C.perfringens in water, using a multipletube dilution technique, with a confirmation procedure for identifying C.perfringens.Refer to AS 4276.1 for a description of the general procedure for estimating the MPN ofmicroorganisms.MPN procedures may be used for the examination of all water samples and are particularlyapplicable for samples containing sufficient suspended material to make filtrationprocedures impractical.NOTE: A flow diagram of the procedure is shown in Appendix A.
