The Particle Science and Technology Laboratory is ISO/IEC 17025-accredited by the American Association for Laboratory Accreditation to calibrate devices that measure particles as small as 10 nanometers in diameter. Recent mask testing at SwRI revealed more than two-thirds of KN95 respirator samples submitted by health care and government clients did not meet U.S. standards for filtration efficiency.
