ASTM E875-20

Standard Practice for Evaluation of Fungal Control Agents as Preservatives for Aqueous-Based Products Used in the Paper Industry

SIGNIFICANCE AND USE
5.1 This practice should be used to determine if a fungal control agent is effective to preserve pigment suspensions, dye solutions, pulp slurries, starch solutions, polymers, sizing agents, latex emulsions, and other specific aqueous-based materials used in the paper industry. Separate evaluations should be made on a representative type for each specific class of product to be preserved.  
Note 1: Control of bacterial spoilage of similar products can be evaluated by Test Method E723.
Note 2: Slimicides for control of fungal or bacterial slime can be evaluated by Test Method E1839.
SCOPE
1.1 This laboratory practice is used to determine the efficacy of a fungal control agent to prevent spoilage of in-process aqueous-based products used in the paper industry.  
1.2 For information on bacterial control agents, see Test Method E723.  
1.3 It is the responsibility of the investigator to determine whether good laboratory practices (GLP) are required and to follow them when appropriate (see 40 CFR 160).  
1.4 A knowledge of microbiological techniques is required for these procedures.  
1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.6 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

3.2 Definitions of Terms Specific to This Standard:

of fungal spores. This term is applied to chemical biocidal or biostatic agents.

This term is applied to chemical biocidal or biostatic agents.
3.2.2 preservative, n—chemical agent used to prevent microbial spoilage of products due to microbial agent(s) added to a product
to reduce or prevent microbial growth.
4. Summary of Practice
4.1 Aqueous material to be preserved is inoculated with an appropriate fungal innoculum followed by addition of a concentration
of fungal control agent that will kill the fungi or prevent their growth for a desired period of time, or both. In addition, the agent
will also prevent fungal spore germination. Fungal growth is determined by visible signs of deterioration in the test sample, and
by obtaining fungal numbers and comparing them to a sample without any fungal control agent. The proper level of fungal control
agent is one that prevents product deterioration and reduces and keeps the organisms to an acceptable level in the test material,
as determined by the tester or user.
