Quantitative surface test for the evaluation of residual antimicrobial ( bactericidal and/or yeasticidal) efficacy of liquid chemical disinfectan ts on hard non-porous surfaces. Test method Ingestion-build-84997 Railway operatorsWhat is this PAS about? Many biocide products, such as liquid disinfectants, claim to have so called residual efficacy: that is they claim to be long lasting, or to offer 24 hour protection, etc. The usual test is to apply the product to a hard surface and leave it there for a defined period of time.
