Shape stability

The legislator gives great responsibility to packers of goods. The goods must always be securely packed for transport. In most European countries, the EUMOS40509 is the relevant standard for measuring the shape stability of a load. This test is also often called the acceleration test.

ESTL's core business is evaluating and optimising the shape stability of cargo units.

If goods behave in a form stable to an acceleration of at least 0.5g according to EUMOS40509, a certificate can be issued. This certificate must be presented at police checks.

The EUMOS sets a number of criteria for the deformation during the test, also known as elastic deformation. This must be limited to 10% of the height. Permanent or plastic deformation is also limited. The deformation in the lower 20 cm of the load unit is limited to 4 cm. The rest of the load may not be deformed by more than 5%. Furthermore, there must be no major permanent damage, such as from a leaking barrel.

If a load does not meet the predefined criteria, you have come to the right place to optimise its stability. For this purpose, ESTL has an extensive lab with different wrapping machines. In addition, ESTL has solid expertise in the field of wrapping film. This is due to the FPT-750 which we manufacture and sell worldwide.

Why form-stable load units?

The form stability of a unit load has the following advantages with regard to load securing:

  • Calculation formulas for the number of fuses can be used. Having a stable load is the condition for applying the formulas. No tests need to be carried out in a secured condition, which does not limit the number of degrees of freedom of your logistics.
  • Legal certainty on the way of stowing.
  • The shipper hereby complies with the requirement for "sufficiently strong transport packaging"(see Load securing RD)
  • The load does not have to be blocked over the entire height. This also makes partial loads much easier, as one does not know in advance which other pallets are in the lorry.
