1 Scope
This British Standard specifies a method of determining the disinfection capability
of processes for enclosures in the human health, veterinary, food, industrial and
institutional sectors using ultraviolet (UV) radiation.
The objective of the processes concerned is to disinfect the surfaces of the overall
area, including the external surfaces, of the equipment contained in such enclosures.
This British Standard is applicable to UV disinfection systems for which microbicidal
activity is claimed against the following types of microorganism:
-
• vegetative bacteria, including mycobacteria;
-
• bacterial spores;
-
• yeasts;
-
• fungal spores;
-
• viruses; and
-
• bacteriophages.
Air disinfection products and water disinfection-based systems are excluded from the
scope of this British Standard.
Manually-applied (i.e. hand-held) UV systems are excluded.
Continuous throughput conveyor type systems, such as food packaging systems, which
typically achieve low decimal log reductions are also excluded.
