Biological examination and assay of metalworking fluids Available to Purchase

Some of the mechanisms involved in the microbial colonisation and biodeterioration of metalworking fluids are described in an attempt to design a more realistic and meaningful laboratory assay procedure. The history of bioassay techniques is reviewed and the nature and composition of metalworking fluids is examined. Maximisation of the performance of biocides against micro‐organisms and the influence of tramp oil contamination is assessed.
