ASTM G21: Resistance of Synthetic Polymeric Materials to Fungi
Overview page of ASTM G21
Scope of ASTM G21
ASTM G21
Standard practice for determining resistance of synthetic polymeric materials to fungi.
Products to be tested
Synthetic polymeric materials.
Description of ASTM G21 Test
- Fungi are grown on solid medium and a spore suspension is prepared from Penicillium, Aspergillus, Chaetomium, Trichoderma, Aureobasidium.
- A small volume of the pooled spore preparation is applied directly to the test samples.
- Petri dishes are sealed and incubated for up to 28 days.
- Samples are given a semi-quantitative based performance score based on fungal growth after 28 days.
Third Party Validation
On passing this test, the product can be labelled as tested by airmid healthgroup to ASTM G21 in support of any claim relating to the test and data received.
Turnaround Time

Accreditation & Compliance for ASTM G21
- iAIR Labs offers high-quality testing, inspection, compliance and certification with several regulatory systems.
- Our labs are routinely, externally audited to ensure that your data is reliable, repeatable, and scientifically accurate. We meet the requirements for submission to both the US EPA and the US FDA.
- Whether you’re interested in early R&D for your product or GLP testing for a 510k, contact us with your testing needs.
Good Laboratory Practices (GLP)
The Good Laboratory Practices were enacted as law in 1978 to ensure that all data submitted to federal regulatory agencies is performed safely and reliably. The GLPs were introduced to assure that a study is conducted by qualified personnel working in well-maintained facilities with appropriate materials and calibrated equipment, using properly designed experiments recorded with clear and complete detailed documentation, overseen by an independent Quality Assurance Unit, and safely archived for audit/inspection by regulatory agents.
EPA GLP
EPA Good Laboratory Practices (GLP) ensures the quality and integrity of test data submitted to the Environmental Protection Agency. The EPA writes regulations, provides guidance, reviews submitted data, inspects for compliance, registers toxic materials, and enforces legal action for violations.
FDA GLP
FDA GLP prescribes good laboratory practices for conducting nonclinical laboratory studies that support or are intended to support applications for research or marketing permits for products regulated by the Food and Drug Administration (FDA). This program supports customers requesting a GLP assessment, as FDA does not provide a certificate of compliance.
At iAIR Labs, we pride ourselves on adhering to the highest standards of regulatory compliance. All our testing services are conducted in strict accordance with FDA and EPA guidelines and cGLP (current Good Laboratory Practice) regulations, ensuring our clients receive results that are both reliable and recognized by regulatory bodies.
