What strength adhesive do you use to adhere a seal to a container? What about a thin film to the top of a tray? What about securing pharmaceuticals in blister packs? All of these adhesive attachments need to be tested. We tested a well know potato chip manufacturer’s package.
Choosing the right testing machine can help lower costs and accelerate product development. Whether a company is buying its first testing system or is looking for a different type of system to perform tests on a new product, purchasing a testing system is an important decision. We’ve put together 10 easy steps to help you select the perfect system for your testing application.
ASTM D1894 is a testing standard designed to measure the friction of plastic film and sheeting. This post should help you understand the basics of the test procedure and help you choose the right equipment to perform this test accurately. For complete instructions and before testing your products to ASTM D1894, please refer to the official specification.
Procedure:
ASTM D903 is one of the most commonly performed adhesive strength tests. An adhesive is bonded to a material and peeled back at 180 degree angle to measure average peel strength. This post is intended to help you understand the basic test procedure and the equipment needed to perform this test with certainty. When you are ready to test your adhesives to this standard, please refer to and follow the steps in the official ASTM D903 specification.
Procedure:
Materials that adhere living tissues together are being used more frequently in surgical procedures as adjuncts to sutures or as replacements. ASTM F2458 – 05 is a standard test method for determining the comparative wound closure strength of tissue adhesives. With the appropriate substrate, F2458 can also be used in quality control testing of tissue adhesives. This test method can be used to compare adhesives for chance of fatigue, type of failure, and environmental changes.
ASTM F2256 describes in detail how to prepare and test tissue adhesives. This standard describes the methods used to compare and characterize different types of adhesives and for manufacturing quality control of the tissue adhesive based medical devices.
Medical professionals are now using tissue adhesives in place of, or in addition to, the standard sutures or staples to close wounds, surgical openings, and other bandage or wound applications. Defining the adhesive strength of these products determines where, how, and when the adhesive can be used in a medical procedure.
Similar to ISO 844, ASTM D1621 is a testing standard designed to measure the compressive properties of rigid cellular plastics (i.e. foam). This post is intended to help you understand the basic test procedure and the equipment needed to perform this test with certainty.
