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. ## Special Controls *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. ## Predicate Devices - Disposable Surgical Gown GD524ME65 ([K212869](/device/K212869.md)) ## Reference Devices - 35g Standard SMMS Surgical Gown ([K221819](/device/K221819.md)) - 35g Reinforced SMMS Surgical Gown ([K221819](/device/K221819.md)) - 43g Standard SMMS Surgical Gown ([K221819](/device/K221819.md)) - 43g Reinforced SMMS Surgical Gown ([K221819](/device/K221819.md)) - 50g Standard SMMS Surgical Gown ([K221819](/device/K221819.md)) - 50g Reinforced SMMS Surgical Gown ([K221819](/device/K221819.md)) - BVB Surgical Gown ([K221819](/device/K221819.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

The type GD524ME65 in K212869 is selected as the predicate device, and the BVB Surgical Gown (Sterile) in K221819 is {10}------------------------------------------------ selected as the reference device. The indications for use for the proposed device, predicate device and reference device are the same. Table 4 Safety and Effectiveness Comparison {11}------------------------------------------------ ## Different - Weight per square The weight per square for the proposed device is different from the predicate device and reference device. However, the difference in the weight per square will not affect the intended use. In addition, the performance testing results demonstrated that the proposed device can meet the barrier protection level 4 requirement as required by PB70. Therefore, this difference will not affect the safety and effectiveness of the proposed device. ## Different - Size The size for the proposed device is different from the predicate device and reference device. The proposed devices are available in 5 product sizes, including S, M, L, XL and XXL. However, the difference in the size will not affect the device performance. Different size can be selected by surgeon's condition. Therefore, this difference will not affect the safety and effectiveness of the proposed device. ## Different - Breaking strength The breaking strength for the proposed device is different from the predicate device and reference device. Although the longitude and latitude breaking strength of the proposed device are smaller than the predicate device and reference device, the longitude and latitude breaking strength of the proposed device meets ASTM F2407-20's requirement of greater than 30N. Therefore, this difference will not affect the safety and effectiveness of the proposed device. ## Different - Tearing strength The tearing strength for the proposed device is different from the predicate device and reference device. However, the longitude and latitude tearing strength of the proposed device meets ASTM F2407-20's requirement of greater than 10N. Therefore, this difference will not affect the safety and effectiveness of the proposed device. ### Different - Seam Strength The seam strength for the proposed device is different from the predicate device and reference device. The shoulder seam strength, sleeve seam strength and armhole seam strength were conducted on the proposed device. The sleeve seam strength and armhole seam strength of the proposed device are smaller than the predicate device, while these seam strengths are similar to the reference device. And {12}------------------------------------------------ these seam strength of the proposed device meets ASTM F2407-20's requirement of greater than 30N.
