A report is presented of studies undertaken by the Plastics Protection Working Group of the International Biodeterioration Research Group to evaluate the nutrient salts agar method as a technique for determining the effectiveness of fungicides in PVC films. 2 refs. 

Furthermore, collaborative testing was carried out by participants in the Polymer Dispersion Group of the International Biodeterioration Research Group (IBRG) in which the viability in polymer dispersions of 175 microbial species was evaluated (Gillatt, 1995) (Table 9). Sixteen representative organisms were selected from... 

A number of methods are available for evaluating the microbial resistance of polymer dispersions and biocides added to them but there are, as yet, no recognised international standards. Nevertheless, the work of the International Biodeterioration Research Group (IBRG) in this field has lead to the production of a draft method (IBRG, 2001), which, it is believed, can be used as an efficacy test for biocides within the scope of the European Biocidal Products Directive and for predicting the in-use performance of polymer dispersion biocides.
