Medical textile barrier vs basic physical methods
Barrier methods (F1670 synthetic blood, F1671 viral-penetration, F2101 bacterial filtration) and specifications (F2100 masks, F2407 gowns, AAMI PB70 classification) address fluid protection; tensile (D5034, D5035), abrasion (D4966) and tear (D1424) address basic physical durability. They answer different questions.
Sample considerations
- ASTM F1670/F1670M: Material, seam/construction, exposure pressure sequence and pass/fail basis
- ASTM F1671/F1671M: Material, seam, exposure sequence and assay interpretation
- ASTM F2100: Mask material, intended performance level and the individual tests referenced
- ASTM F2101: Material, challenge organism/aerosol setup and flow conditions
- ASTM F2407/F2407M: Gown construction, critical zones and referenced barrier/physical tests
- AAMI PB70: Article type, barrier level sought and the referenced test methods
- ASTM D5034: Fabric, direction, specimen preparation and conditioning
- ASTM D5035: Fabric, strip type, direction and conditioning
- ASTM D4966: Fabric, abradant, pressure and endpoint criteria
- ASTM D1424: Fabric, direction, specimen geometry and instrument capacity
