ASTM F3505-21 - Standard Test Method for Stent and Endovascular Prosthesis Kink Resistance

1.1 This standard addresses the kink resistance of stents and endovascular prostheses (for example, stent grafts). The standard may also be applicable to scaffolds.

1.2 Test methods presented herein address the kink resistance of stents and endovascular protheses when exposed to bending in a single plane. While concurrent influences (for example, torque) are recognized to influence kinking properties, test methods other than single-plane bending are not addressed.

1.3 Test methods presented herein do not specifically address kink resistance of branched (for example, bifurcated) or multicomponent endovascular prostheses, but some aspects of this standard may be applicable to their application.

1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
