Abstract
FLT85-1 is a meltblown nonwoven fabric reference material (RM) with a relative particle filtration efficiency near 0.85 (85 %). This material is intended for the determination of particle filtration efficiency for respiratory protection devices. Reference values for FLT85-1 have been established at the National Research Council of Canada (NRC). A unit of FLT85-1 contains a minimum of twenty individual sheets.
