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