The objective of this Standard is to specify a method, using membrane filtration, for enumerating coliforms, Escherichia coli (E. coli) and thermotolerant coliforms in water other than packaged water.

The major changes in this edition are as follows:

(a) Combine the methods of AS/NZS 4276.5 with AS/NZS 4276.7.

(b) Incorporate chromogenic selective media that are capable of enumerating coliforms, Escherichia coli and thermotolerant coliforms in a more timely manner.

(c) Incorporate culture media and reagents.

(d) Remove reference to AS 4276.2.

(e) Update reference cultures.

(f) Update the normative and informative references.
