Test method Ingestion-build-59651 the second using a systemWhat is PAS 2424 Disinfectant test methods 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. However because the surface is undisturbed following application, such a test may not reflect reality. PAS 2424 by contrast
