technique, provided a barrier to blood and body fluids, provide filtration of sub-micron particles, and provide a tight face fit. Uses include, but are limited to, laser surgery where exposure to laser plume is expected, surgical procedures that generate blood aerosols, and areas in the hospital where masks providing a tight face fit are desirable.

Salient characteristics. Mask, Surgical (Sub-Micron), shall be a disposable, cup shaped, molded design, with two elastic bands secured with staples. The area of the body of the mask which fits over the bridge of the nose shall have an aluminum malleable nose-piece centrally located on the mask 1/4 in. (6mm) from the perimeter seal and firmly cemented to the outside surface. A foam strip that fits over the bridge of the nose shall be attached on the inside of the mask. The nose-piece shall be easily formed to the contour of the wearer’s nose to minimize the loss of expired air between the mask and the face in this area. The filtering efficiency of the mask shall not be less than 99% when tested by the method of Greene and Vesly (J.Bacteriol., vol. 83, No. 3, p. 663, March 1982), and no less than 80% efficiency (20% penetration) when tested by DOP (dioctyl phthalate) submicron filtration efficiency test, ASTM D2986-71. Delta P shall not be more than 2.2 ± 0.2 (MMH20). The mask shall be fluid resistant as defined by meeting the following requirement when tested in accordance with hydrostatic pressure test method ASTM D583-63 Method II (AATCC 127-1985):

Minimum average – 6.0 cm

Sample size – 15 Masks
