Functional Fluids

Functional Fluids are defined as products that are supplied as a concentrate, diluted with water by an end-user and then circulated round an industrial plant to perform a function such as cooling, lubrication, corrosion prevention, etc. Examples of these fluids are metalworking fluids, lithographic solutions, textile spin finishes, cooling water and paper pulp etc. All of these are susceptible to microbiological attack and the biocides used in them are covered by the European Biocidal Products Regulation (BPR).

The initial objectives of the Group will be the development of simple test methods to enable the efficacy criteria of the BPR to be met. Later, more detailed investigation will be undertaken of other factors involved in the biodeterioration of functional fluids.

    Tier 1 Basic Efficacy of Biocidal Active Substances used as Slimicides in Aqueous-Based Paper Pulps
    This document describes a method for determining the basic efficacy of biocidal active substances in aqueous based paper pulps and is intended for the generation of data to enable registration of active substances. Samples containing the active substance under test are inoculated with defined suspensions of microorganisms and then incubated. The changes in the size of the populations over time are used to determine the basic antimicrobial properties of the active substances being evaluated. It is important to note that the results obtained may not describe the performance of the active substance under normal conditions of use.

    This document describes a method for determining the basic efficacy of biocidal active substances in aqueous-based cooling fluids and is intended for the generation of data to enable registration of active substances. Samples containing the active substance under test are inoculated with defined suspensions of microorganisms as consortia and then incubated. The changes in the size of the populations over time are used to determine the basic antimicrobial properties of the active substances being evaluated. It is important to note that the results obtained may not describe the performance of the active substance under normal conditions of use.

  • Standard Practice for Evaluating Water-Miscible Metalworking Fluid Bioresistance and Antimicrobial Pesticide Performance
    http://www.astm.org/Standards/E2275.htmAbstract...
    This practice provides laboratory procedures for rating the relative bioresistance of metalworking fluid formulations, for determining the need for microbicide addition prior to or during fluid use in metalworking systems and for evaluating microbicide performance.
