YY/T 0506 consists of the following parts under the general title Surgical drapes, gowns and clean air suits for patients, clinical staff and equipment: ——Part 1: General requirements for manufacturers, processors and products; ——Part 2: Performance requirements and test methods; ——Part 4: Test method for linting in the dry state; ——Part 5: Test methods for resistance to dry microbial penetration; ——Part 6: Test method to determine the resistance to wet bacterial penetration; ——Part 7: Test methods for determination of cleanliness-microbial; ——Part 8: Special requirements for products. This is Part 8 of YY/T 0506. This part is developed in accordance with the rules given in GB/T 1.1-2009. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. The issuing body of this document shall not be held responsible for identifying any or all such patent rights. This part was proposed by the National Medical Products Administration of People’s Republic of China. This part is under the jurisdiction of Shandong Quality Inspection Center for Medical Devices. Introduction The YY/T 0506 standard series specify the requirements for single-use and reusable coverings (i.e., surgical gowns, surgical drapes, and clean air suits) for patients, clinical staff and equipment. These products, as medical equipment, are designed to prevent the transmission of infectious agents between patients and clinical staff during traumatic operation. During the implementation of the published YY/T 0506 standard series, it was found that the requirements specified in YY/T 0506.2-2016 focused on requirements for fabrics, while surgical drapes, surgical gowns and clean air suits meeting the requirements of YY/T 0506.2-2016 does not necessarily mean that they also meet the relevant clinical requirements, such as special requirements on structure, seams, fluid control, etc. Therefore, developing this part of YY/T 0506 is necessary. This part of YY/T 0506 is designated to: ——further standardize the requirements for surgical drapes, surgical gowns and clean air suits on the basis of Parts 1 and 2 of YY/T 0506; ——provide further guidance to manufacturers of surgical drapes, surgical gowns and clean air suits (specified in YY/T 0506) for their design of products. Note: See YY/T 0506.1 for further information on the products covered by this part. The requirements for the surgical drapes specified in this part of YY/T 0506 are applicable to but not limited to: general surgical drapes, neurosurgical surgical drapes, thoracic surgical drapes, abdominal surgical drapes, urological surgical drapes, gynecologic surgical drapes, intraocular surgical drapes, head and neck surgical drapes, orthopedic surgical drapes, limb surgical drapes, joint replacement surgical drapes, cardiovascular surgical drapes, cardiovascular intervention surgical drapes, caesarean surgical drapes, cystoscope surgical drapes, thyroid surgical drapes, breast surgical drapes, hip surgical drapes, spine surgical drapes, shoulder joint surgical drapes, hernia surgical drapes, lithotomy surgical drapes, etc. Surgical drapes, gowns and clean air suits for patients, clinical staff and equipment - Part 8: Special requirements for products 1 Scope This part of YY/T 0506 specifies the special requirements for surgical drapes, gowns and clean air suits for patients, clinical staff and equipment. This part is applicable to surgical drapes, gowns and clean air suits that are used in operations with high requirements for purification and where the full body of the patient is required to be fully covered. Note: The surgical drapes specified in this part do not include single-use and reusable surgical drapes that are used in small operations with small wound openings and low requirements for purification. The clinical requirements for surgical drapes, gowns and clean air suits used in the operating room depend on the size of the surgical wound and the purification level of the clean operating room. 2 Normative references The following referenced documents are indispensable for the application of this document.
