ISO 9727-5
ISO 9727-5 belongs to the series of ISO 9727, which set test methods to determine the performance of medical needles for use in healthcare applications. This portion of the standard is directed at assessing the needle-to-hub bonding, which is a key parameter in determining the safety and performance of sterile needle assemblies. This test measures the force needed to pull the needle from the hub under controlled conditions, which allows the manufacturer to assess the integrity of the needle in the hub. Presto products provide precision tensile testing solutions to enable accurate and repeatable bond strength testing as per ISO 9727-5.
Significance
The connection between a needle and its hub must remain secure during storage, handling, and clinical use. A poor bond can lead to needle dislodgement, putting patients at risk and decreasing product performance. The strength of this connection can be measured using a standardized procedure set out in ISO 9727-5 and the results used to determine if the assembly is sufficiently strong to withstand the forces it will experience during normal use. Test data can be used by manufacturers to verify their production processes, to ensure the quality of the products, and to ensure that the products meet the regulatory and industry standards. Manufacturers of medical devices depend on this kind of testing to help guarantee the safety, reliability, and uniformity of manufacturing. Scope ISO 9727-5 covers the determination of the force required to separate a needle tube from its hub using a tensile testing procedure under specified laboratory conditions. The standard applies to all sterile medical injection, infusion, and other needle-based devices for healthcare use. Test results may be used to monitor quality control, facilitate product development, validate processes, and qualify suppliers. Presto's tensile testing devices provide precision and repeatability for manufacturers to ensure assembly integrity and compliance with international medical device standards.
