The biomedical industry uses tissue adhesives for applications such as bandages, secondary dressings, wound closure, and surgical sealants. The adhesive strength of these products must be clearly defined before using in a clinical setting. If the adhesive is not strong enough, the product may lead to infection or poor healing. If the adhesive is too strong, the underlying tissue may become damaged upon removal. This standard describes a test methodology for both development and characterization of these adhesives, as well as for quality control. When developing and characterizing the material properties of these adhesives in combination with soft tissue substrates, it is important to consider the environmental conditions.
The challenges of testing to this standard are:
Testing in real world conditions
Accurately recording adhesive strength
It is important to review ASTM F2256-05(2015) to fully understand the test setup, procedure, and results requirement
