YY/T 0694-2008 Standard test method for measuring intrinsic elastic recoil of balloon-expandable stents

1.1 The purpose of this test method is to quantify the expansion diameter of the stent on the balloon and the post-decompression diameter of the stent after the balloon is removed, as well as the stent diameter retraction rate. This test method is suitable for stents made of materials that can undergo plastic deformation under mechanical action before and after expansion. This test method can be carried out at room temperature, unless certain materials have special temperature requirements. The test temperature should be specified in the report (if applicable). 1.2 This standard does not cover all safety issues related to use. It is the responsibility of the users of this standard to determine its applicability by establishing appropriate safety and health evaluation mechanisms before use.

YY/T 0688.1-2008 Clinical laboratory testing and in vitro diagnostic test systems—Susceptibility testing of infectious agents and evaluation of performance of antimicrobial susceptibility devices—Part 1:Reference method for testing the in vitro activity of antimicrobial agents against rapidly growing aerobic bacteria involved in infectious diseases

This part of YY/T 0688 introduces a reference method for determining the MIC value of antimicrobial agents—the broth microdilution method. The MIC value only reflects the antibacterial activity of the antimicrobial agent under the specified in vitro test conditions. When formulating a medication regimen, doctors should not only refer to the MIC results, but also consider other factors such as the pharmacokinetic/pharmacodynamic parameters of the drug in the human body and the bacterial resistance mechanisms to the antimicrobial agent. For a certain antimicrobial agent, the corresponding test bacteria can be divided into "sensitive (S)", "intermediate (I)" and "resistant (R)" according to the results of the in vitro sensitivity test (MIC value). In addition, the MIC value can be used to determine whether the test strain is a wild-type or non-wild-type. Although interpreting the clinical significance of the MIC value is beyond the scope of this part, it is necessary to adjust the basic content of the method according to different combinations of antimicrobial agents and bacteria to meet clinical needs. These adjustments are reflected in the following tables. To ensure the comparability and reliability of the test results, other antimicrobial susceptibility testing methods (such as conventional methods or antimicrobial susceptibility testing equipment) should be compared with this reference method to determine their accuracy.
