ISO 14607:2024 Annex E – Cohesion testing*

Kohäsionsprüfung ISO 14607:2024 BrustimplantateWe offer cohesion testing of silicone gel according to ISO 14607:2024 Annex E. In this test, only the filling is examined, not the shell. The silicone filling material is poured into a funnel with standardized dimensions and surface roughness. The gel is allowed to flow freely through the funnel’s lower opening for a duration of (30.0 ± 0.1) minutes.

During the test, it is observed whether the flowing filling material separates from the remaining volume in the funnel. If the material remains cohesive as a whole, the length of the portion hanging below the funnel is measured. We would be happy to provide you with a quotation for this test.

ISO 14607:2024 Annex C.3 – Endurance load test / FDA Docket No. 2004D-0124

FDA Docket No. 2004D-0124 Dauerschwingversuch*ISO 14607:2024 Annex C.3 and the document Docket No. 2004D-0124 from the U.S. Food and Drug Administration (FDA) describe fatigue tests on breast implants aimed at developing a Wöhler (S–N) curve. Unlike the fatigue tests under shear stress according to ISO 14607, the implants in the FDA guideline Docket No. 2004D-0124 are subjected to cyclic compressive loading. Sinusoidal load cycles with defined upper and lower loads are applied up to a run-out level of 6.5 million cycles. We offer this test together with static rupture tests according to ISO 14607:2007.

ISO 14607:2024 Annex C.2 – Impact testing*

Aufprallprüfung BrustimplantateFor the impact test according to ISO 14607:2024 Annex C.2, INNOPROOF has developed and built a custom drop rig that ensures a standard-compliant test. Depending on the mass and projection height of the breast implant, the required drop height is calculated. A weight of 4.4 kg is held by an electromagnet, and the drop height is set using a measuring device. The test specimen is placed centrally on the test table. When the electromagnet is switched off, the weight is released, initiating the impact.

After the impact test, the breast implant undergoes a visual inspection. To pass the test, no damage to the shell may be visible.

ISO 14607:2024 Annex C.1 – Fatigue testing*

Ermüdungsprüfung BrustimplantateISO 14607:2024 describes in Annex C.1 the fatigue testing of breast implants under shear stress. The implant is placed between two horizontally arranged plates, and a static load of 50 N per implant is applied. Using an eccentric drive, one of the plates is moved back and forth, applying shear stress to the implant. The test is conducted over 6.5 million cycles at a frequency of 3.33 Hz. Afterwards, an optical rupture inspection is performed.

We offer this test as a service and can test six breast implants of various sizes simultaneously on our test rig. We would be happy to provide you with a quote.

ISO 14607:2024 Annex B – Shell testing*

Prüfverfahren Brustimplantat ISO 14607:2024 Anhang B Prüfung der HülleAs part of our testing services for breast implants, we offer, among other things, tests to assess the integrity of the shell in accordance with ISO 14607:2024, Annex B. These include tests of the shell’s elongation, measurement of tensile set after sustained elongation, and testing of seam strength.

For the shell tests mentioned above, specimens are first prepared using a standardized die. INNOPROOF has a corresponding cutting die in accordance with ISO 37:2017, Type 2, enabling us to obtain specimens directly from the breast implants. All tests are performed under tensile loading using our Zwick universal testing machine. We would be pleased to provide you with a quotation for these testing services.

Mechanical testing of sports shoes

Which mechanical tests on sports shoes does our laboratory offer?

In the sole fatigue test, the running behavior of a jogger performing hundreds of thousands of steps is simulated. The sole is repeatedly loaded and unloaded to realistically reproduce long-term use. Afterwards, the ability of the sole to recover and return to its original shape is evaluated. In addition, changes in cushioning, stiffness, and other mechanical properties caused by long-term cyclic loading are analyzed.

In this test, various sole materials such as EVA, TPU, or PEBA are subjected to defined impact loads. The objective is to objectively measure the cushioning behavior and energy absorption of the individual foam materials. After the loading tests, the materials are compared with respect to their mechanical properties. This makes it possible to determine which foam provides the best performance under identical conditions.

Impact and drop tests simulate hard impact loads such as those occurring during running or jumping. In particular, the heel area is subjected to defined impact forces. Measurements determine how effectively the shoe absorbs and distributes impact energy. In addition, the tests evaluate whether material damage or permanent deformations occur.

In bending and torsion tests, the shoe is repeatedly bent and twisted to replicate natural foot movements. These tests show how flexible or stiff the shoe is in both longitudinal and transverse directions. At the same time, it is evaluated whether materials or bonded joints begin to separate over time. The results provide important information about the stability and wearing comfort of the shoe.

Shear testing evaluates how well materials and material joints withstand lateral forces. Controlled shear forces are applied to the sole or to bonded interfaces between different layers. The objective is to assess adhesion strength and structural stability. This makes it possible to determine whether materials shift or separate under lateral loading.

Which types of sports shoes are tested?

  • Running shoes (road, trail, competition)
  • Football boots (natural grass, artificial turf, indoor)
  • Basketball shoes
  • Handball shoes
  • Volleyball shoes
  • Tennis shoes
  • Fitness and training shoes
  • Hiking shoes
  • Climbing shoes
