Medical Laboratory Testing: Mildew, Mold, and Fungi
Mildew, mold, and fungi testing shows how well materials resist fungal growth in humid conditions. The test inoculates specimens, incubates them in high humidity, and rates visible growth and damage. For medical manufacturers, strong antifungal performance helps protect products, improve hygiene, and reduce infection risk.
Healthcare environments often stay warm and humid, so fungi grow easily on textiles and polymers. Even minor growth can weaken barriers, create odors, and raise cleanliness concerns. Applus+ Reliable Analysis offers accredited fungal resistance testing that supports water repellency, humidity, and barrier performance programs.
These evaluations support key standards for protective apparel and reusable medical products. Manufacturers use the data to qualify materials that stay clean, functional, and durable after moisture exposure. Reliable Analysis delivers consistent, reproducible results under ISO/IEC 17025 accreditation.
Common Mildew, Mold, Fungi Medical Testing Standards:
AATCC 30 Antifungal Activity Mildew and Rot Resistance of Textiles
AATCC 30 evaluates the resistance of textiles to mildew and rot by inoculating specimens with specific fungal strains and incubating them under high-humidity conditions. After a set period, the test rates the amount of fungal growth and any loss of strength. This method is widely used for surgical gowns, drapes, scrubs, and medical textiles to ensure materials resist fungal colonization in humid clinical or storage environments, helping maintain barrier performance and reduce infection control risks.
ASTM G21 Determining Resistance of Synthetic Polymeric Materials to Fungi
ASTM G21 tests how well synthetic polymers, plastics, coatings, and foams resist fungal growth. The standard inoculates specimens with mixed fungal spores and incubates them under warm, humid conditions. It rates visible growth from 0, meaning no growth, to 4, meaning heavy growth.
This test helps verify that medical device housings, cushioning pads, tubing, and positioning aids will not support mold or mildew. It also helps preserve structural integrity and cleanliness over time.
ISO 16869 Plastics Assessment of the Effectiveness of Fungistatic Compounds
ISO 16869 determines the effectiveness of fungistatic additives in plastics by inoculating specimens with fungal spores and evaluating growth after incubation. The standard provides a clear rating system for fungal resistance. It is particularly relevant for medical plastics, flexible components, and coated materials used in devices that may be exposed to humid conditions, helping manufacturers ensure long-term resistance to mold and mildew while maintaining biocompatibility.
