Sheng Jing Tang Surgical Mask is intended for use in healthcare settings, procedures during which a face mask is necessary to protect both patient and healthcare personnel from transfer of body fluids, microorganisms, and particulate material. The device is indicated to be over-the-counter use. Adult only. The device is disposable and is indicated for single use. The device is not provided sterile.
The Sheng Jing Tang Surgical Masks are composed of 3-layers and are flat-pleated provided blue color, the mask materials consist of an outer layer (Spun-bond polypropylene), Inner layer (Spun-bond polypropylene), Middle Layer filter (Polypropylene Melt-blown Cloth), Ear-loops (Spandex + Nylon, Ear Loops way for wearing) and Nose piece (a Polyethylene + Galvanized Iron wire nosepiece to provide a firm fit over the nose and then to secure the mask over the users' mouth and face). The Sheng Jing Tang Surgical Masks are single use, disposable device, adult only, provided non-sterile.
This document describes the premarket notification (510(k)) for the Sheng Jing Tang Surgical Mask. The "acceptance criteria" and "study that proves the device meets the acceptance criteria" refer to the non-clinical performance and biocompatibility testing conducted to demonstrate substantial equivalence to a predicate device.
Here's the breakdown of the information requested, based on the provided document:

§ 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.
