The medical surgery mask mask is intended to be worn to protect and healthcare personnel from transfer of microorganisms, body fluids and particulate material. These masks are in infection control practices to reduce the potential exposure to blood and body fluids. This is a single use, disposable device(s), provided non-sterile.
The medical surgery mask is pleated three-layer mask with ear loops and nose piece. The outer layer is made of spun-bonded polypropylene (PP) non-woven fabric. The middle layer with filtration function is made of melt blown polypropylene (PP) fabric. The inner layer contact with face is made of spun-bonded polypropylene (PP) non-woven fabric. The medical surgery mask is only the outer layers' color is blue (colorant: Pigment Blue 15:3/Model:147-14-8), which is held to cover the users' mouth and nose by two spandex elastic bands ultrasonic welded to the medical surgery mask.The inner layer is white. The elastic ear loops are not made with natural rubber latex. The nose piece contained in the medical surgery mask is in the middle layer of medical surgery mask to allow the user to fit the medical surgery mask around their noses, which is made of malleable aluminum wire.
The dimensions of each medical surgery mask are length 175±5 mm and width 95±5 mm, The dimensions of nose piece is length 120±10 mm, and the ear loop is length 180±10 mm. The mask model 2626-7 meets level 3 performance requirements in ASTM F2100.The medical surgery masks are sold non-sterile and are intended to be single use,disposable devices.
The provided text describes the acceptance criteria and the study that proves a medical surgery mask meets these criteria, specifically for a 510(k) premarket notification (K220067) for the Medical Surgery Mask, Model: 2626-7.
Here's a breakdown of the requested information:

§ 878.4040 Surgical apparel.
(a)
Identification. Surgical apparel are devices that are intended to be worn by operating room personnel during surgical procedures to protect both the surgical patient and the operating room personnel from transfer of microorganisms, body fluids, and particulate material. Examples include surgical caps, hoods, masks, gowns, operating room shoes and shoe covers, and isolation masks and gowns. Surgical suits and dresses, commonly known as scrub suits, are excluded.(b)
Classification. (1) Class II (special controls) for surgical gowns and surgical masks. A surgical N95 respirator or N95 filtering facepiece respirator is not exempt if it is intended to prevent specific diseases or infections, or it is labeled or otherwise represented as filtering surgical smoke or plumes, filtering specific amounts of viruses or bacteria, reducing the amount of and/or killing viruses, bacteria, or fungi, or affecting allergenicity, or it contains coating technologies unrelated to filtration (e.g., to reduce and or kill microorganisms). Surgical N95 respirators and N95 filtering facepiece respirators are exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to § 878.9, and the following conditions for exemption:(i) The user contacting components of the device must be demonstrated to be biocompatible.
(ii) Analysis and nonclinical testing must:
(A) Characterize flammability and be demonstrated to be appropriate for the intended environment of use; and
(B) Demonstrate the ability of the device to resist penetration by fluids, such as blood and body fluids, at a velocity consistent with the intended use of the device.
(iii) NIOSH approved under its regulation.
(2) Class I (general controls) for surgical apparel other than surgical gowns and surgical masks. The class I device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to § 878.9.
