Professional Mould Growth and Fungal Resistance Testing
PRIDE TESTING LAB provides support for Mould Growth Testing in Delhi NCR for manufacturers, OEMs, product developers, electrical and electronic equipment manufacturers, material suppliers, railway and industrial product companies, and other organizations that need to evaluate the effect of fungal or mould exposure on products and materials.
Mould growth can affect products used, stored, or transported in warm and humid environments. Depending on the material and application, fungal exposure may contribute to surface deterioration, material degradation, staining, changes in physical properties, or functional concerns.
The applicable test method should always be selected according to the product type, material, intended environment, applicable standard, customer specification, and acceptance criteria.
What Is Mould Growth Testing?
Mould growth testing, also called fungal growth testing or fungus resistance testing, evaluates whether a product or material can support mould growth and how fungal exposure may affect its performance or other relevant properties.
For electrotechnical products, IEC 60068-2-10:2005+A1:2018 provides Test J and guidance for mould growth. It evaluates the extent to which products support mould growth and how that growth may affect performance and other relevant properties.
For synthetic polymeric materials, ASTM G21-15(2021)e1 is a recognized practice for determining resistance to fungi and may evaluate effects on physical, optical, mechanical, and electrical properties, as applicable.
Why Is Mould Growth Testing Important?
Products intended for warm and humid environments may be exposed to conditions favourable for fungal growth.
Depending on the product and material, mould exposure may contribute to:
- Surface growth
- Discoloration
- Material deterioration
- Coating degradation
- Changes in physical properties
- Changes in optical properties
- Electrical insulation concerns
- Electrical performance changes
- Surface contamination
- Functional reliability concerns
ASTM G21 notes that, for polymeric materials, fungal attack may be associated with susceptible components such as plasticizers, cellulosics, lubricants, stabilizers, or colorants rather than the polymer itself.

- Material composition
- Technical datasheet
- Product application
- Intended operating environment
- Storage conditions
- Applicable testing standard
- Customer specification
- Required acceptance criteria
2. Selection of the Applicable Test Method
The appropriate test method depends on the specimen and testing objective.
Relevant standards may include:

- Customer-specific requirements
The exact edition required by the customer, contract, or product specification should always be confirmed before testing.
3. Specimen Preparation
The test specimen is prepared according to the applicable test method.
Preparation may consider:
- Specimen identification
- Material condition
- Product configuration
- Surface condition
- Preconditioning requirements
- Electrical or functional setup, where applicable
For mould testing under IEC 60068-2-10, the applicable method includes defined specimen preparation, fungal inoculation, and incubation requirements.
4. Fungal Inoculation and Controlled Exposure
Depending on the selected method, specimens may be exposed to defined fungal spores and controlled incubation conditions.
The environmental conditions are designed to promote fungal germination and growth according to the applicable standard.
IEC 60068-2-10 describes test approaches involving inoculation and incubation, while ASTM G21 evaluates fungal effects on applicable synthetic polymeric materials.
5. Incubation Period
The specimen remains under the required controlled conditions for the period specified by the applicable test method.
The required duration should not be assumed from a generic testing schedule.
For IEC 60068-2-10:2005+A1:2018, the incubation duration was reduced from the earlier 84-day approach to 56 days as part of changes described by IEC.
6. Inspection and Evaluation
After the required exposure period, specimens may be evaluated according to the applicable standard or specification.
Evaluation may include:
- Visible mould growth
- Surface condition
- Discoloration
- Material deterioration
- Product functionality
- Electrical characteristics
- Mechanical properties
- Other product-specific performance parameters
The applicable acceptance criteria should be defined by the governing standard or product specification.
7. Test Documentation
Depending on the agreed testing scope, documentation may include:
- Product or specimen identification
- Applicable test method
- Test configuration
- Test conditions
- Exposure or incubation period
- Inspection observations
- Measurements, where applicable
- Acceptance criteria
- Final results
Mould Growth Testing Standards
IEC 60068-2-10
IEC 60068-2-10:2005+A1:2018 covers environmental testing for mould growth under Test J.
The method is intended to determine the extent to which electrotechnical products support mould growth and how such growth may affect performance and other relevant properties. IEC lists the consolidated 2018 version as valid.
ASTM G21
ASTM G21-15(2021)e1 is a standard practice for determining the resistance of synthetic polymeric materials to fungi.
It covers applicable moulded and fabricated polymeric materials, including tubes, rods, sheets, and films, with relevant changes in material properties evaluated through applicable methods.
A revision work item exists, so customers should verify the edition required by their project or specification before testing.

Frequently Asked Questions About Mould Growth Testing
What is mould growth testing?
Mould growth testing evaluates whether a product or material can support fungal growth and assesses the effect of that growth on relevant product or material properties.
What is the difference between mould testing and fungal resistance testing?
The terms are often used in related contexts. Mould growth testing may focus on the extent of fungal growth and its effects on a product, while fungal resistance testing may focus on how well a material resists fungal attack.
The exact method depends on the applicable standard and product.
Which standards are used for mould growth testing?
Commonly referenced standards include IEC 60068-2-10 for mould growth of applicable electrotechnical products and ASTM G21 for resistance of synthetic polymeric materials to fungi.
How long does mould growth testing take?
The duration depends on the applicable test method and specification. IEC’s mould growth method describes a 56-day incubation duration in the current consolidated IEC 60068-2-10 version.
Which products may require mould growth testing?
Electrical, electronic, industrial, railway, polymeric, insulated, coated, and other products intended for humid environments may require mould or fungal resistance testing, depending on their applicable specification.
Is mould growth testing the same as humidity testing?
No. Humidity testing evaluates product performance under controlled temperature and humidity conditions. Mould growth testing specifically evaluates fungal growth and its effects under conditions designed to support such growth.
