Launching a disinfectant product without scientifically validated efficacy can delay product registration, affect customer confidence and create regulatory challenges. Manufacturers need independent laboratory evidence that their products perform as claimed before entering the market.
Envirocare Laboratory provides ISO/IEC 17025:2017 SANAS-accredited disinfectant efficacy testing using recognised South African National Standards (SANS). Our laboratory performs SANS 51276 bactericidal testing and SANS 51650 fungicidal and yeasticidal testing, helping manufacturers demonstrate product performance for regulatory submissions, quality assurance and commercial confidence.
For most routine projects, testing can be completed with a turnaround time of approximately five working days, allowing manufacturers to move products to market more quickly.
Why Accredited Disinfectant Testing Matters
Independent laboratory testing provides objective evidence that a disinfectant consistently achieves the required microbial reduction under controlled conditions.
Accredited testing helps manufacturers:
- support product registration
- demonstrate regulatory compliance
- validate antimicrobial claims
- satisfy customer and retailer requirements
- support GMP and quality management systems
- compare new formulations against existing products
Using an accredited laboratory also ensures testing is performed using validated methods with full traceability.
SANS 51276 – Bactericidal Efficacy Testing
SANS 51276 is the recognised South African standard for evaluating bactericidal activity in food, industrial, domestic and institutional environments. It is harmonised with the European EN 1276 standard.
Testing evaluates a disinfectant against important bacterial organisms including:
- Escherichia coli
- Staphylococcus aureus
- Pseudomonas aeruginosa
- Enterococcus hirae
To comply, products are expected to achieve the required bacterial log reduction under specified clean and soiled test conditions.
SANS 51650 – Fungicidal and Yeasticidal Testing
SANS 51650 evaluates whether disinfectants effectively eliminate fungi and yeasts commonly encountered in food production, pharmaceutical manufacturing and industrial facilities. It is based on the internationally recognised EN 1650 method.
Typical challenge organisms include:
- Candida albicans
- Aspergillus brasiliensis
Successful testing demonstrates that a product delivers effective fungicidal and yeasticidal performance under defined laboratory conditions.
