ASTM E2562

ASTM E2562 is a laboratory standard for quantifying Pseudomonas aeruginosa biofilm grown under high shear and continuous flow using a CDC Biofilm Reactor. It provides a controlled test method for measuring biofilm development in a defined reactor environment, which helps support consistent evaluation of antimicrobial performance, biofilm control strategies, and comparative testing. By focusing on a repeatable growth and measurement approach, the standard is useful for technical work where reliable biofilm quantification matters.

What is ASTM E2562?

ASTM E2562 is a standard test method centered on the quantification of Pseudomonas aeruginosa biofilm produced with high shear and continuous flow in a CDC Biofilm Reactor. In practical terms, it describes a structured way to grow and assess biofilm under conditions that are more controlled than ad hoc laboratory methods. This makes the test method valuable when a consistent biofilm challenge is needed for product evaluation, method comparison, or quality-focused laboratory testing.

Where is ASTM E2562 used?

ASTM E2562 is commonly used in laboratory and research settings that evaluate biofilm-related performance under controlled flow conditions. It is especially relevant for testing programs involving the CDC Biofilm Reactor, where repeatable growth conditions are important for measuring Pseudomonas aeruginosa biofilm. The standard may support development work, comparative testing, and quality control activities where biofilm quantification is needed to assess cleaning, control, or treatment approaches.

Why is ASTM E2562 important?

ASTM E2562 matters because it helps create a more consistent basis for biofilm testing and interpretation. A defined test method can improve comparability between laboratories, reduce variability in results, and support more reliable product evaluation. For organizations working on biofilm control, the standard may also aid procurement decisions, performance verification, and technical compliance by providing a clear framework for quantifying biofilm grown under high shear and continuous flow conditions.
