Floor coatings in kitchens face grease, tomato sauce, red wine, and coffee. A flooring that fails E2109-01 would become permanently stained within months, looking unsanitary.
: High porosity often leads to lower tensile strength and fatigue resistance. Thermal Conductivity
The 2015 version does not invalidate the 2001 edition, but it supersedes it for new testing. If you are auditing a lab or writing a protocol, always check whether the client or regulator demands the 2001 or 2015 edition.
The magnification must be high enough to resolve the smallest pores of interest but low enough to capture a representative area. 5. Data Reporting According to ASTM E2109-01, a formal report should include:
: Technicians compare a cross-section of the coating under high magnification against a series of standard reference images that represent various porosity levels.
