Test methods evaluating the water resistance of garments will be discussed later in this document.CONSTRUCTION MATERIALS TESTING TEST METHOD SELECTION LIST Consequently, some test methods that use water as a challenge agent may not be representative for evaluating the barrier effectiveness of the healthcare PPE and may overestimate the effectiveness of the PPE for blood-borne pathogens. This is because liquids with higher surface tension, like water (0.070–0.072 N/m), are more likely to bead on a surface than liquids with lower surface tension, which are more likely to wet and penetrate through the garment. Within the context of gowns and coverall testing, the surface tension of the challenge liquid is critical. Synthetic blood has a surface tension (0.042 ± 0.002 Newton per meter ) and viscosity representative of blood and some body fluids (see Table 2 for surface tension of the body fluids). The synthetic blood used for these tests is a mixture of cellulose, coloring, buffer solution, and stabilizing agents.
#ASTM STANDARDS LIST ISO#
ASTM F1670 and ISO 16603 are “screening-tests” that evaluate the resistance of a material to synthetic blood penetration.
