1 Quantitative leakage testing is optional for ASTM F3502. Leakage is reported as a ratio of the particle concentration outside the face covering over particle concentration inside the face covering. Higher leakage ratios indicate less leakage.

2 See Making Enhanced Performance Barrier Face Coverings for requirements for Enhanced Performance and Enhanced Performance Plus masks. Quantitative leakage criteria are required in addition to the ASTM F3502 requirements for particulate filtration efficiency and breathability.

3 Three Barrier Face Coverings meeting NIOSH recommendations before June 2023 were labeled “MEETS WORKPLACE PERFORMANCE” and “MEETS WORKPLACE PERFORMANCE PLUS.”
