8. Limitations of E2109-01

Not suitable for very soft PSAs (e.g., gel adhesives) that creep excessively before failure.
Does not account for cyclic or dynamic loads.
Does not predict failure under humidity or chemical exposure directly (requires separate conditioning).
The standard was reapproved in 2012 but not updated to 2023 version; some users now reference ASTM D3654/D3654M-22.

Method A – Time-Kill (Dynamic Contact) Test

Purpose: To determine the rate and extent of microbial kill over specific time intervals (e.g., 0, 6, 24, 48 hours, 7 days, 14 days, 28 days).
Procedure: A known concentration of antimicrobial agent is mixed with a standardized bacterial or fungal suspension under continuous agitation (dynamic conditions).
Outcome: Log reduction in viable microorganisms compared to a neutralizer control.

Purpose: To monitor the effects of spray parameters and evaluate the suitability of a coating for its intended use by quantifying voids or "linear detachments" within the material. Measurement Methods: astm e2109-01 pdf

If you absolutely need the 2001 edition, buy it from ASTM International. The $60 investment ensures you have a legally admissible, error-free document. Never rely on free downloads—misplaced decimal points, missing pages, or incorrect neutralizer formulas can cause failed audits or product recalls. The Mysterious Document 8

ASTM E2109-01(2021) defines standard test methods for evaluating the area percentage porosity in thermal sprayed coatings, covering both manual comparison and automated image analysis. This standard is crucial for quality control in surface engineering, allowing for the assessment of coating density and conformity to specifications.
