ASTM E1839-07

Standard Test Method for Efficacy of Slimicides for the Paper Industry—Bacterial and Fungal Slime

SIGNIFICANCE AND USE
This test method is to be used to determine if a slime control agent has application in the paper industry for control of bacterial or fungal slime.
This test method is run in acid, alkaline, or acid and alkaline conditions to determine the efficacy of the slime control agent.
The test conditions may be modified to reflect intended use patterns in typical paper mill systems, including use of actual paper mill furnish.
SCOPE
1.1 This test method presents a procedure to evaluate the efficacy of slimicides for the control of bacterial and fungal slimes in paper mill systems and their counterparts.
1.2 It is the responsibility of the investigator to determine whether Good Laboratory Practices (GLP) are required and to follow them where appropriate (40 CFR 160).
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.
