Fatigue Testing Stent Materials and Structures. Traditional testing of stent and stent grafts (to standards such as ASTM F2477) involves subjecting complete devices to pressure pulsation simulating blood flow for a pre-specified number of cycles. Even if the device has not fractured, a simple pass/fail criterion is used for the test to succeed.

The user should justify the appropriate testing for the specific absorbable material and device. 1.4.1 While the primary purpose of this guide is to address absorbable stent-related issues specific to the tests described in 1.4, additional testing (for example, radial strength) will likely also be needed.
ASTM F88 is a test method that covers the measurement of the strength of seals in flexible barrier materials and can also be conducted on seals between a flexible material and a rigid material. This test method measures the force needed to separate a seal and figures out the mode of specimen failure. Tensile testing seal strength is a method ...
December 4, 2023. Compressive strength is a fundamental parameter that informs the safety, quality and durability of a particular mix of concrete. Testing according to ASTM C39 is central to the QA/QC process. For over 80 years, ASTM C39 has been the industry standard test method for testing the compressive strength of concrete cylinder …

The ASTM E8/E8M standard is one of the most influential standards in material testing, specifically in tension testing of metallic materials. This method is used for quality control, material comparisons, and alloy development to evaluate the mechanical properties of metals. ASTM E8/E8M assesses uniaxial tensile strengths and ductility of …
The annexes in this standard provide absorbable-specific testing recommendations for evaluations where an ASTM test method for durable (that is, non-absorbable) stents is already available. ... pulsatile durability (F2477), FEA of stents (F2514), three-point bending (F2606), ... additional testing (for example, radial strength) will likely also ...
Scope. 1.1 This test method determines the flatwise tensile strength of the core, the core-to-facing bond, or the facing of an assembled sandwich panel. Permissible core material forms include those with continuous bonding surfaces (such as balsa wood and s) as well as those with discontinuous bonding surfaces (such as honeycomb).
1. Scope* 1.1 These test methods cover the tension testing of metallic materials in any form at room temperature, specifically, the methods of determination of yield strength, yield point elon- gation, tensile strength, elongation, and reduction of area. NOTE1—A complete metric companion to Test Methods E 8 has been developed, therefore, no ...
The stent design or intended use might dictate the need to address functional requirements identified in both ISO 25539-1 and this document (e.g. stents used in combination with endovascular prostheses, stents used to treat aortic aneurysms). Balloons integral to the stent system are within the scope of this document.
