In a Test Report (Example)

"Stain resistance was evaluated according to ASTM E2109-01. Three specimens of each floor covering were tested using the seven staining agents specified in Section 7 of the standard. Results were rated using the ASTM gray scale for staining, where 5 = no staining and 1 = severe staining."

4. Procedure Overview

1. Conditioning: Specimens and panels at 23°C ± 2°C, 50% ± 5% RH for at least 24 hours.
2. Bonding: Apply PSA to panel with roller, ensuring no air bubbles.
3. Dwell: Allow bond to stabilize under no load.
4. Loading: Hang the specified weight from the free end of the specimen.
5. Timing: Record time from load application to failure (complete separation).
6. Repeat: Minimum 5 replicates per condition.
7. Reporting:
   • Individual failure times
   • Mean, median, range
   • Failure mode (adhesive/cohesive)
   • Test temperature and humidity
   • Load magnitude

ASTM E2109-01 is a critical technical standard used to determine the area percentage porosity astm e2109-01 pdf

in thermal sprayed coatings (TSCs). It provides a systematic approach for evaluating the density and quality of coatings produced by methods like Atmospheric Plasma Spraying (APS), High-Velocity Oxy-Fuel (HVOF), and Cold Gas Spray (CGS). ResearchGate Core Purpose and Scope

The standard outlines procedures for rating the porosity of metallographic specimens prepared according to ASTM E1920

. Porosity is a vital metric because it directly influences a coating's mechanical properties, such as hardness and wear resistance, as well as its corrosion protection and thermal insulation capabilities. Key Methodology The standard details two primary measurement techniques: Method A (Manual Comparison): The Complete Guide to ASTM E2109-01: Understanding the

Porosity is assessed by direct comparison of the specimen's microstructure against a set of standard referential images. Method B (Automated Image Analysis):

This more common modern approach uses computerized algorithms and software (such as

) to calculate the area fraction of pores from digital micrographs. ResearchGate Measurement Process Test Method Selection:

To ensure statistical accuracy, the following steps are typically followed in professional labs:

TEST REPORT: DETERMINATION OF AREA PERCENTAGE POROSITY

Reference Standard: ASTM E2109 – 01 (Reapproved 2020)

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.
