SUGGESTED INTERNATIONAL TEST FOR DISINFECTANTS.

Evaluation of a Virucidal Quantitative Carrier Test for Surface Disinfectants

Surface disinfectants are part of broader preventive strategies preventing the transmission of bacteria, fungi and viruses in medical institutions. To evaluate their virucidal efficacy, these products must be tested with appropriate model viruses with different physico-chemical properties under conditions representing practical application in hospitals. The aim of this study was to evaluate a q...

Testing disinfectants for efficacy.

Testing under laboratory conditions is undoubtedly useful in assessing the activity of disinfectants. However, such testing must be regarded as no more than a preliminary to field trials. This not only indicates the unreliability of laboratory tests, but also poses the wider problem of how any laboratory evaluation can be correlated with the field requirements. Many attempts have therefore been...

International Test Conference Monday

1.1 1:30 p.m. "An Efficient Self-Test Structure for Sequential Machines" S.Z. Hassan Rolm Mil-Spec Computers In this paper, a BIST structure for sequential machines is presented. The approach requires augmentation of the machine by the addition of an extra input and some logic. The test sequence is independent of the function implemented and depends only on the number of input combinations and ...

Should test methods for disinfectants use vertebrate viruses dried on carriers to advance virucidal claims?

izontal surfaces in the rooms of patients with C. difficile infection. It would be obtuse to assume that in vitro experiments precisely simulate in vivo conditions. Similarly, relying solely on an antimicrobial agent's minimum inhibitory concentration to predict its clinical efficacy against a particular infecting pathogen is ill-advised. Thus, it is standard practice to employ in vitro models ...
