YY/T 0693-2008 Standard guide for characterization and presentation of the dimensional attributes of vascular stents

1.1 This standard includes the identification of vascular prosthesis size attributes related to clinical performance and effectiveness, as well as recommended testing methods. This standard also includes the packaging and special markings of the delivery system during stent placement. 1.2 This standard only specifies the size characteristics of stents. It does not address the material properties and functional characteristics of stents. All size characteristics described in this standard refer to in vitro test ("bench test") characteristics. Due to various factors in patients, such as vascular compliance, there may be slight differences in actual in vivo test characteristics.

YY/T 0695-2008 Standard test method for conducting cyclic potentiodynamic polarization measurements to determine the corrosion susceptibility of small lmplant devices

1.1 This test method utilizes cyclic (forward and reverse) electrochemical polarization to evaluate the corrosion sensitivity of small metal implantable medical devices or their components. The devices that can be evaluated using this test method include, but are not limited to, the following products: vascular stents, urethral stents, filters, supporting components of intravascular grafts, heart occluders, aneurysm clips and ligature clips, U-shaped nails, etc. 1.2 This test method is used to evaluate implantable devices in their final finished form. These small devices should be tested in their complete form. The upper limit of the device size depends on the maximum output current of the testing instrument (see Chapter 6). It is assumed that test methods such as ASTM G 5 and ASTM G 61 can be used for material screening tests.

YY/T 0700-2008 Clothing for protection against contact with blood and body fluids—Determination of the resistance of protective clothing materials to penetration by blood and body fluids—Test method using synthetic blood

This standard specifies the test method for determining the resistance of protective clothing materials to penetration by blood and body fluids. This test method uses the test instruments specified in YY/T 0699 to continuously expose protective clothing materials to synthetic blood under a set of specified conditions.
This test method may not be effective for protective clothing materials with thick, easily absorbent synthetic blood linings.

YY/T 0702-2008 Control material for hematology analyzer

This standard specifies the terms and definitions, naming and classification, technical requirements, test methods, inspection rules, marking, labels and instructions, packaging, transportation, and storage of quality control materials (hereinafter referred to as quality control materials) for blood cell analyzers. This standard does not provide technical requirements for the white blood cell classification diagram of quality control materials.
This standard applies to quality control materials for blood cell analyzers, which are used to monitor or evaluate the accuracy of the detection results of blood cell analyzers (also known as hematology analyzers).

YY/T 0704-2008 Ultrasonics—Pulsed Doppler diagnostic system—Test procedures to determine performance

This standard specifies: — Test methods for measuring the performance of pulsed Doppler ultrasound systems; — Doppler test pieces used for conducting these tests. This standard applies to: — Testing of complete pulsed Doppler ultrasound systems that have not been disassembled into subsystems or had their interconnections disconnected; — Testing of pulsed Doppler ultrasound systems, which may be standalone or part of other ultrasound instruments. This standard does not address electrical safety, acoustic safety, and electromagnetic compatibility (EMC). In general, it would be impractical to conduct all the aforementioned tests, so it is expected that a subset will be selected for routine use. However, it is still necessary to gather experience to guide the selection process and serve as the subject of ongoing research.
