This part of YY/T 0606 is applicable to sodium alginate used in the preparation of tissue engineering medical products and surgical implants.
This standard specifies the graphical symbols for dental equipment, which will be used in the corresponding equipment components and in the documentation of the corresponding dental equipment components, such as the user manual. All dental equipment has specific symbols. Most of the symbols come from relevant IEC and ISO international standards.
This standard specifies the performance and safety requirements for high-capacity and medium-capacity suction systems, as well as their testing procedures. It also includes requirements for the user manuals, marking, and packaging of the production plants. This standard applies to high-capacity and medium-capacity suction systems that form part of dental equipment. Where applicable, when the provisions of this standard are specified, the requirements of this standard shall take precedence over the general standard GB 9706.1—2007. This standard does not apply to low-capacity suction systems.
This standard specifies the requirements and testing methods for the materials, design, and structure of the water and gas supply systems for dental treatment units, to ensure that the quality of the water and gas supplied to dental treatment units is up to standard, including provisions to prevent the reflux of oral fluids into the water supply of dental treatment units. This standard does not specify measures to prevent the contamination and/or spread of dangerous microorganisms (such as bacteria, viruses, etc.).
This standard specifies the basic requirements and test methods for handheld frame-type and head-mounted indirect ophthalmoscopes.
This standard does not apply to the condenser lens used in indirect ophthalmoscopes and its accessories.
This standard does not apply to table-mounted instruments such as Gullstrand ophthalmoscopes and derivative instruments of this type, nor to ophthalmoscopes used for image capture and/or processing, such as those employing laser scanning technology.
This standard specifies the requirements for the information provided by manufacturers for reagents used in biological staining. This standard applies to manufacturers, suppliers, and retailers of dyes, staining agents, luminescent reagents, and other reagents used in biological staining. In all fields of biological staining, the requirements for information provision by manufacturers specified in this standard are a prerequisite for obtaining comparable and reproducible results.
This standard specifies the general requirements for passive surgical implants (hereinafter referred to as implants). This standard does not apply to dental implants, dental restoration materials, implant-fixed devices implanted into dental pulp and roots, and intraocular lenses. Regarding safety, this standard stipulates requirements for expected performance, design attributes, materials, design evaluation, manufacturing, sterilization, packaging, and manufacturer-provided information, as well as tests to verify compliance with these requirements. Other tests are provided in secondary and tertiary standards.
This standard applies to medical diagnostic ultrasound fields within the frequency range of 1 MHz to 15 MHz.
This part of YY/T 0651 specifies the relative angular motion between the joint components in the wear test of total hip prostheses, the test load diagram, the test speed and duration, the shape of the specimen, and the requirements for the test environment.
This part of YY/T 0651 specifies the methods of evaluating the wear of the acetabular component using the mass method and the volume method after conducting the wear test of the total hip joint prosthesis according to YY/T 0651.1.
This standard specifies the sampling method for particles generated from total joint prostheses implanted in the human body or from joint wear testing machines. The standard also prescribes methods for separating polymer and metal particles, as well as instruments, reagents, and testing methods for characterizing and quantitatively analyzing these particles, which originate from tissues around prostheses removed during revision surgery or autopsy, or from the liquid test medium in joint wear testing machines. The methods specified in this standard do not quantitatively grade the wear of joint prostheses, nor do they determine the specific amount of wear on the joint surface. This standard does not cover the biological effects of particles or provide methods for evaluating the biological safety of particles. The methods listed in this standard are not applicable to measuring polymethyl methacrylate (PMMA) particles.
This standard specifies the terminology and definitions, classification, requirements, test methods, labels and instructions for use, packaging, transportation, and storage of blood analyzers. This standard applies to blood analyzers (hereinafter referred to as analyzers) that conduct qualitative and quantitative analysis of formed elements in human blood and provide related information. This standard does not apply to reticulocyte analyzers.
