**Abstract**
 A discussion is presented of factors which need to be considered in the design and testing of a new biocide for plastics applications. In Europe, biocides are becoming more tightly regulated under the Biocidal Products Directive, which requires a significant data package for the registration of new actives and existing formulations. Once the issue of compatibility has been addressed, the antimicrobial efficiency has to be established. Prior to selection of a test method to demonstrate such efficacy, consideration is given to whether the substrate should be pre-conditioned to simulate end-use conditions, e.g., by artificial leaching or weathering. Advantages and disadvantages of traditional test methods are discussed, and an alternative method for the evaluation of biocidal performance is presented, which is claimed to be more representative of end-use conditions.
