What is BS EN 13704 - Quantitative suspension test of chemical disinfectants about?
BS EN 13704 is applicable to chemical disinfectants. BS EN 13704 specifies a test method (phase 2/step 1) and the minimum requirements for sporicidal activity of chemical disinfectant products that form a homogeneous, physically stable preparation in hard water and that are used in food, industrial, domestic and institutional areas, excluding areas and situations where disinfection is medically indicated and excluding products used on living tissues except those for hand hygiene in the above-considered areas.
Who is BS EN 13704 - Quantitative suspension test of chemical disinfectants for?
BS EN 13704 on quantitative suspension test of chemical disinfectants is useful for:
- Processing, distribution and retailing of food of animal and vegetable origin 
- Institutional and domestic areas like catering establishments, public areas, public transports, schools, nurseries, shops, sports rooms, clinically non-sensitive areas of hospitals 
- Other industrial areas such as packaging material, biotechnology (yeast, proteins, enzymes...), pharmaceutical, cosmetics and toiletries, textiles, space industry, a computer industry 
- Testing laboratories 
Why should you use BS EN 13704 - Quantitative suspension test of chemical disinfectants?
BS EN 13704 guides you with a suspension test method for establishing whether a chemical disinfectant has a sporicidal activity in the fields.
BS EN 13704 guides you for closely simulating practical conditions of application. Chosen conditions (contact time, temperature, in suspension, etc.) reflect parameters that are found in practical situations including conditions that can influence the action of disinfectants. Each utilization concentration found from this test corresponds to defined experimental conditions.
What’s changed since the last update?
BS EN 13704:2018 supersedes BS EN 13704:2002, which is withdrawn.
EN 13704:2018 includes the following changes compared to EN 13704:2002:
- Inclusion of spore suspension susceptibility controls
- Modification of spore preparation procedures
- Inclusion of spore maturation time
- Harmonization of counting and elaboration of the results with the other cen/tc 216 current standards
- Deletion of obligatory conditions for contact time and temperature
- Inclusion of minimum and maximum conditions for contact time and temperature
- Inclusion of dirty conditions
