What is BS EN 1650 - Evaluation of fungicidal or yeasticidal activity of chemical disinfectants and antiseptics about?
BS EN 1650 specifies a test method and the minimum requirements for fungicidal or yeasticidal activity of chemical disinfectant and antiseptic products that form a homogeneous, physically stable preparation when diluted with hard water or - in the case of ready-to-use-products - with water. Products can only be tested at a concentration of 80 % or less as some dilution is always produced by adding the test organisms and interfering substances.
BS EN 1650 applies to products 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.
BS EN 1650 helps you to determine the bactericidal or fungicidal or yeasticidal activity of chemical disinfectants and antiseptics used in food, industrial, domestic and institutional areas.
Who is BS EN 1650 - Evaluation of fungicidal or yeasticidal activity of chemical disinfectants and antiseptics for?
BS EN 1650 on chemical disinfectants and antiseptics 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 1650 - Evaluation of fungicidal or yeasticidal activity of chemical disinfectants and antiseptics?
BS EN 1650 provides principles and laboratory conditions recommendations for suspension tests for establishing whether a chemical disinfectant or antiseptic has fungicidal or yeasticidal activity in the fields.
BS EN 1650 considers practical conditions of application of the product including contact time, temperature, test organisms and interfering substance. This helps you to influence the action of disinfectants in practical use.
Each utilization concentration of the chemical disinfectant or antiseptic found by this test corresponds to defined experimental conditions.
What’s changed since the last update?
BS EN 1650:2019 supersedes BS EN 1650:2008+A1:2013, which is withdrawn.
The main changes in relation to EN 1650:2008+A1:2013 are:
- Inclusion of hand hygiene
- Hand rub and handwash test conditions and test requirements have been harmonized with EN 13624
- Interfering substances for breweries, soft drinks, cosmetics and cleaning in place have been deleted. A sentence to allow additional interfering substances for specific applications has been added
- The obligatory conditions (temperature and contact time) have been deleted. The text has been harmonized with EN 13624 keeping specified time intervals and temperature steps
