Superseeded by:
Significance and Use:

5.1 This practice should be used to determine if an antimicrobial preserves pigment suspensions, dye solutions, pulp slurries, starch solutions, polymers, sizing agents, latex emulsions, and other aqueous-based materials used in the paper industry from bacterial spoilage.

Note 1Control of fungal spoilage of similar products can be evaluated by Test Method E875.
Note 2Slimicides for control of fungal or bacterial slime can be evaluated by Test Method E1839.

1.1 This laboratory practice is used to determine the efficacy of an antimicrobial for preventing bacterial spoilage of in-process aqueous-based products used in the paper industry. For information on fungal spoilage, see Test Method E875. This practice should be performed by persons who have had basic microbiological training.

1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. (See 40 CFR Part 160.)
