ISO 846 Evaluation of the Effect of Microorganisms on Plastics

ISO 846 Evaluation of the Effect of Microorganisms on Plastics

ISO 846 Evaluation of the Effect of Microorganisms on Plastics is a standardized method used to assess the resistance of plastic materials to microbial attack, including bacteria and fungi. ISO 846 Evaluation of the Effect of Microorganisms on Plastics is critical for materials used in humid and biologically active environments.

Purpose

• Evaluate microbial growth on plastics
• Assess biodegradation and surface damage
• Test antimicrobial properties
• Determine material durability

Test Methods

• Method A: Fungal growth
• Method B: Bacterial action
• Method C: Growth with nutrient source

Test Conditions

• Temperature: 28–30°C
• High humidity (>90%)
• Duration: 2–4 weeks

Conclusion

ISO 846 Evaluation of the Effect of Microorganisms on Plastics ensures material resistance to microbial degradation and supports long-term performance validation.
