Test types

Further or specific test types in this section

breakaway (slip) torque

Friction keeps a closure secure, and reduces as a screw thread is turned.

bridge torque

Where a tamper-evident collar or band is employed, these are often attached by a series of ‘bridges’, pulled apart as the cap

reverse ratchet torque

In two-part CRCs, the outer shell engages the inner with a one-way ratchet when pressed down.

strip torque

A closure may be over-tightened, rendering the seal ineffective, damaging the thread, or making it either too difficult to op

"Mecmesin's Tornado testers are very easy to use. Even people who had no experience in this area found them simple to operate. We achieved very reliable results and found that the Tornadoes were easily adapted to test many different bottles and pots. The machines produced printed paper results or a digital file and we found this was a very easy way of keeping opening torque records. They are a very useful instrument for packaging."

"Mecmesin, through their Portuguese supplier Egitron, presented us with a good solution: reliable equipment and user-friendliness that was adequate for our needs. All our operators are capable of using this equipment because it is very simple to operate. I enjoy dealing with Egitron because they offer excellent technical support."

The Mecmesin penetrometer provides accurate low strength data (up to 1 MPa) as soon as you can start testing. This data can immediately be shared with the Shotcrete crews working underground. The instrument and accessories have brought benefits through easy transportation and has the ability to be used for shotcrete trials, where the samples are shot to be cored at a later date. This has eliminated the need to transport additional samples.

The Millennium Seed Bank had a need to quantify the tightness of screw capped glass bottles used for long term storage of wild plant seed. Having established the optimum torque, the Orbis 6 N.m is used routinely to maintain the correct tightness of the bottles. The design of the Orbis makes it simple to use and easy to adapt to different containers.

"We perform a variety of tests on our pump products. One of which is to evaluate their release torque. In order to precisely apply torque to screw and unscrew the pumps, we use Mecmesin equipment. These instruments prove their value to us through their ease-of-use and accuracy."
