ASTM  D2574 : 2016 –  Standard Test Method for Resistance of Emulsion Paints in the Container to Attack by Microorganisms

ASTM D2574 is designed to determine the resistance of emulsion paints incorporated with biocides against microbial contamination. It is an IN-CAN biocide preservative test to check the efficacy of the biocide.

In ASTM D2574 test procedure, product sample is challenged with test microorganisms 2 times weekly.

Importance of ASTM D2574 Test

Bacterial and fungal growth on paint surfaces is not only insighty but also reduces their expected shelf life due to the process of deterioration.

In order to ensure the durability and efficacy of emulsion paints, ASTM D2574 test helps manufacturers with regard to these two things –

  • in the selection of the most effective preservatives 
  • evaluation of the efficacy of preservatives with other competitive preservatives

The accuracy of results for ASTM D2574 standard strictly depends upon laboratory techniques practiced for efficacy testing. It is advisable that manufacturers may contact the suppliers of raw materials and biocides if product sample is unable to meet acceptance test criteria.

At MIS, we carry out both standard and customized protocols for ASTM D2574 based on clients testing needs and requirements.
