ASTM D2574
ASTM D2574 Standard Test Method for Resistance of Emulsion Paints in the Container to Attack by Microorganisms
What is ASTM D2574?
ASTM D2574 is the Standard Test Method for Resistance of Emulsion Paints in the Container to Attack by Microorganisms. This method evaluates the susceptibility of water-based paints and coatings to microbial growth, such as bacteria, yeasts, and molds, when stored in closed containers. Ensuring resistance to microbial attack is essential for product quality, shelf life, and regulatory compliance.
Why Test for Microbial Resistance?
- Prevent Spoilage: Avoid paint spoilage, odor, discoloration, and viscosity changes caused by microbial contamination.
- Ensure Product Stability: Maintain paint properties and performance over the intended shelf life.
- Protect Brand Reputation: Deliver consistently high-quality products to your customers.
Our ASTM D2574 Testing Process
- Sample Preparation: Representative paint samples are collected and prepared according to ASTM D2574 protocols.
- Inoculation: The paint is inoculated with a mixed culture of microorganisms known to cause spoilage in water-based coatings.
- Incubation: Samples are incubated at 30oC for up to two weeks.
- Evaluation: After incubation, our experts inspect samples for visible signs of microbial growth, changes in appearance, odor, or consistency.
