BS EN 1275 Fungicidal and Yeasticidal Activity Testing for Chemical Disinfectants
Airmid Healthgroup provides independent, ISO/IEC 17025-accredited BS EN 1275 testing services — delivering quantitative fungicidal and yeasticidal efficacy data for disinfectant and antiseptic manufacturers seeking European market access, BPR regulatory compliance, and third-party validated product claims.
European Regulatory Standard for Fungicidal Claims
BS EN 1275 is the harmonised European standard for evaluating the basic fungicidal and yeasticidal activity of chemical disinfectants and antiseptics. It is a core requirement under the EU Biocidal Product Regulation (BPR) for any product making fungicidal or yeasticidal claims in European markets.
Scope of BS EN 1275
BS EN 1275 specifies a quantitative suspension test method for the evaluation of basic fungicidal or yeasticidal activity of chemical disinfectant products. It is applicable to products used in food, industrial, domestic, and institutional areas.
The standard uses Candida albicans as the primary test organism — a clinically relevant yeast and opportunistic pathogen — to assess the ability of a disinfectant to achieve a defined reduction in fungal viability under standardised conditions.
BS EN 1275 Testing Protocol
How the BS EN 1275 Test Works
- Product Preparation: The disinfectant product is prepared at the intended use concentration and assessed for compatibility with the test method.
- Fungal Suspension Preparation: A standardised suspension of Candida albicans is prepared and quantified to ensure a defined starting concentration of viable organisms.
- Contact Exposure: The product is mixed with the fungal suspension under controlled temperature conditions for the specified contact time, with an appropriate interfering substance to simulate clean or dirty use conditions.
- Neutralisation: The reaction is stopped immediately after the contact period by adding a neutralising agent — preventing any further disinfectant activity during subsequent analysis.
- Enumeration: The surviving fungi are recovered, serially diluted, and plated on appropriate agar. Colony forming units (CFUs) are counted after incubation to determine the number of viable organisms remaining.
- Log Reduction Calculation: The fungicidal/yeasticidal efficacy is expressed as the log₁₀ reduction in viable organisms compared to the untreated control — a ≥4 log₁₀ reduction is required to pass.
Why BS EN 1275 Testing Matters
BPR Regulatory Compliance
BS EN 1275 data is required for EU Biocidal Product Regulation (BPR) dossier submissions for products claiming fungicidal or yeasticidal activity — essential for legal market access in Europe.
Professional Procurement
Healthcare, food processing, and institutional buyers require independently validated fungicidal data for procurement decisions and infection control protocols.
Claims Substantiation
Third-party validated fungicidal data supports marketing claims, enabling manufacturers to substantiate “kills fungi,” “antifungal,” and “yeasticidal” product statements.
Competitive Differentiation
Independent validation differentiates products in the market — demonstrating fungicidal performance against clinically relevant organisms under standardised, repeatable conditions.
Products That Can Be Tested
- Household and commercial disinfectants and sanitisers
- Food contact surface disinfectants
- Healthcare and hospital-grade disinfectants
- Industrial and manufacturing facility disinfectants
- Mould and mildew removal products
- Bathroom and kitchen cleaning products

Accreditation & Third-Party Validation
Airmid Healthgroup’s ISO/IEC 17025-accredited, GLP-compliant laboratory delivers independently validated results accepted by the EU BPR authority, EPA, and FDA. All testing is conducted in strict accordance with cGLP regulations.
On passing BS EN 1275 testing, products can be labelled as independently tested by Airmid Healthgroup to BS EN 1275 standards — supporting fungicidal and yeasticidal claims in marketing, regulatory submissions, and professional procurement specifications.

Frequently Asked Questions
What is the difference between fungicidal and yeasticidal activity?
Fungicidal activity refers to the ability of a product to kill filamentous fungi — moulds such as Aspergillus and Penicillium. Yeasticidal activity refers to the ability to kill yeasts such as Candida albicans. BS EN 1275 specifically evaluates yeasticidal activity using Candida albicans as the test organism, which is broadly accepted as representative of basic fungicidal performance for disinfectant classification purposes.
Why is the contact time longer for BS EN 1275 than for BS EN 1276?
Fungi and yeasts are generally more resistant to chemical disinfectants than bacteria — requiring a longer contact time to achieve the required log reduction. BS EN 1275 uses a 60-minute contact time compared to the 5-minute contact time used in BS EN 1276 for bactericidal testing, reflecting this difference in organism susceptibility.
Can BS EN 1275 be combined with BS EN 1276 bactericidal testing?
Yes. Airmid routinely conducts BS EN 1275 alongside BS EN 1276 and other EN standard tests as part of an integrated disinfectant efficacy programme — providing manufacturers with a complete antimicrobial profile from a single testing programme.
What log reduction is required to pass BS EN 1275?
A ≥4 log₁₀ reduction (99.99% kill rate) in viable Candida albicans is required within the specified contact time to achieve a fungicidal/yeasticidal claim under BS EN 1275.
What will I receive after BS EN 1275 testing?
You will receive a full GLP-compliant test report detailing the methodology, test conditions, log₁₀ reduction calculations, pass/fail conclusion, and all raw data — ready for use in BPR dossiers, regulatory submissions, and marketing claims.
