The Testing Times

A Luer fitting is the common name for a tapered fitting that adheres to ISO 594. In this case it was necessary to hold a needle which had a Luer attachment on it. this was to be used for puncture testing, so no thread was required. Used as in conjunction with S0994, this test used a range of standard needles with Luer ends. This simple needle or luer attachment could be used for any number of compression, puncture tests on components with Luer ends.

This Grip is used to test the bodies of Sharps Containers. As you might imagine, it is very important that 'sharps' cannot penetrate the sides of the container. This grip is used to hold a fine needle in one end, and a sample of the moulded box the other. There is a piece of foil underneath the specimen , this allows the system to know when the needle has punctured right through. An accurate measurement of the force required is then taken. The needle holder rotates allowing the user to insert the needle without bending over or risking hurting themselves with the needle. The base is a simple stand with hole, the connection to the foil is made with a clip.

The Tinius Olsen S0616 is used to hold a standard syringe for testing fittings. It makes use of the end of the syringe, whilst holding it in place. The plunger cannot be used whilst in this grip; this is a method of testing the end fittings not the syringe. There are a variety of fittings that attach to a standard syringe, the most common of which is a standard Luer fitting. We do a few grips to hold Luer fittings, but it’s sometimes just as easy to hold the syringe and use that as the ‘grip’ end. The materials are correct, syringes are cheap, and it’s a real world test. If there is any damage to the syringe it can be easily replaced…
