Do international standards for hygienic handrubs reflect realistic usage

Hygienic handrubs are widely used in healthcare to reduce the probability of pathogens being spread via the hands. International standards such as EN 1500[1] have been developed to ascertain the efficacy of handrubs claiming antimicrobial action. This standard compares a reference product (2 x 3ml applications of 60% v/v isopropanol (IPA) over 60 seconds) with a test product(s). However, as WHO guidelines[2] recommend that drying times are limited to 30 seconds, does the standard represent realistic usage?
