ASTM D5589 – Antialgal Test

The ASTM D5589 method is an antimicrobial test intended to determine the algae resistance of paint films and related coatings.

Under certain environmental conditions such as lighting or temperature, painted or coated surfaces may be susceptible to algal defacement. This accelerated test allows to evaluate paint or coating film resistance to algae growth. The ASTM D5589 method allows for the evaluation of various coating formulations in order to assess their relative antialgal performance.

Test samples are placed on algal growth media and inoculated with the selected algae culture. Following inoculation, samples are placed in a high humidity environment with day and night light cycling. Algal growth is evaluated on weekly basis during a three-week testing period.
