In-house testing of straps and components

Testing straps takes place at our headquarters in The Netherlands where we have our own testing facility. We do this because we care about quality and road safety. As our mission says: “We want to make transport more safer and efficient.”. Therefore, we not only test our own straps, but we do also from our competitors. This we do only to make transport companies aware of possible risks and dangers. From our own experience we see that not every brand meet the European requirements.

Our straps always meet the strict standards as described in the European norm EN-12195-2. To make sure our quality stays at the highest level, we randomly test straps we produce (according the ISO 9001 norm).

HOW WE TEST OUR STRAPS

We test our straps thoroughly on:

  • Webbing
  • Hardware
  • And the complete assembly 

Webbing

In the European norm straps are not allowed to elongate more than 7%, while the LoadLok norm is based on 4% elongation (apart from a few exceptions).The webbing of a strap has to withstand a force tension force of at least 3 times the LC value. So a the webbing of a standard LC2500 daN lashing only breaks at 7500daN+!

Before production of the lashing, these tests are performed in order to make sure the webbing is according to the norm.These tests are made on a calibrated, certified load cell and routinely expected to ensure the usage of the GS sign.

Hardware

End fittings have to be thoroughly inspected on sharp edges and burrs, to ensure no injuries will occur to the operators hands.
There is no specific requirement for corrosion resistance, however the most common method used is the NSS-test as specified in ISO 9227.
For the tensioning devices, the same rules apply and more. Parts of the additional tests consist of; the cyclic loading test, ability of the device to be released under tension and the recoil test.

Complete assembly

After a visual inspection of the complete lashing, ensuring that no sharp edges and burrs come into contact with the webbing or the operators hands, the product is ready to be force tested. The lashing is loaded to 1,25 times the LC value and maintained in that position for 1 minute.
All load bearing parts of the complete product are not allowed to show deformations or defects that affect the function of the lashing.
Any permanent deformation of the rotating axes of the tensioning device has to be less than 2% of the webbing width, that is for 50mm lashing only 1mm! After this test, the complete assembly is subjected to a force of 2 times LC.

A test report for each strap

After all proper testing, a LoadLok test report according to EN 12195-2 will at least consist of the following results: 

  • If the complete product fails during the test.
  • If damages have occurred to the surface of the webbing
  • Any signs of deformation on both the fittings and the ratchet
  • Maximum tensile force applied and illustrated
  • No failures occur at force of two times LC
  • mean value of the pre-tension force and the level obtained
  • results of the cyclic loading test
  • result of the handle strength test
  • result of re-tests
