Bending Testing

Our Service

Meditronics (a brand of STEMart) offers accurate and reliable bend testing in accordance with leading international standards, ensuring compliance with FDA, ISO 13485, and MDR requirements. Our testing services include:

• ISO 14125 (Fiber-Reinforced Plastic Composites – Determination of Flexural Properties)
  Method: Three-point or four-point bending test to measure flexural strength and modulus.
  Results: Flexural stress-strain curve, elastic modulus, and failure mode analysis.
  Application: Orthopedic implants, prosthetics, and reinforced medical devices.
• ASTM F2606 (Standard Guide for Three-Point Bending of Balloon-Expandable Vascular Stents)
  Method: Cyclic bending to simulate vascular movement and assess fatigue resistance.
  Results: Number of cycles to failure, coating integrity, and deformation limits.
  Application: Cardiovascular stents and endovascular implants.
• ISO 7438 (Metallic Materials – Bend Testing)
  Method: Mandrel or free-form bending to evaluate ductility and surface defects.
  Results: Minimum bend radius, crack formation, and fracture toughness.
  Application: Surgical tools, metal implants, and guidewires.
• ASTM E290 (Standard Test Methods for Bend Testing of Material for Ductility)
  Method: Guided bend test (180° or 90°) to assess material flexibility.
  Results: Pass/fail criteria based on crack formation after bending.
  Application: Metallic alloys used in medical devices.
• ISO 178 (Plastics – Determination of Flexural Properties)
  Method: Three-point bending to measure stiffness and strength.
  Results: Flexural modulus, yield strength, and strain at break.
  Application: Polymer-based medical components (e.g., syringes, casings).
• ASTM D790 (Standard Test Methods for Flexural Properties of Unreinforced and Reinforced Plastics)
  Method: Three-point or four-point bending with controlled strain rates.
  Results: Flexural stress, strain, and modulus for rigid/flexible plastics.
  Application: Medical packaging, catheters, and disposable devices.
• ASTM D7264 (Flexural Properties of Polymer Matrix Composite Materials)
  Method: Four-point bending to evaluate interlaminar shear strength (ILSS).
  Results: Flexural strength, stiffness, and failure mechanisms.
  Application: Composite-based implants and surgical instruments.
