Quick answer: EUMOS 40509 is a European test method for how stable a wrapped pallet load is. The load is put on a platform that speeds up and brakes sharply, and the test measures how far the load leans or deforms. To pass, it mustn’t deform by more than 10% of its height during the test, mustn’t stay more than 5% out of shape afterwards, and mustn’t show any damage to the goods or packaging. Most businesses never need a formal test, but the same things that pass it, such as a strong base, even tension and the right film, make any pallet safer on the road.

If you ship goods abroad, or supply customers with strict packaging rules, you may have come across EUMOS 40509. It sounds like dense technical jargon, but the question it answers is simple. Will your load stay put when the lorry carrying it brakes hard or takes a sharp bend?

What EUMOS is

EUMOS is the European Safe Logistics Association, a group that writes standards for load safety. EUMOS 40509 is its test method for the rigidity of a load unit, which in practice usually means a wrapped pallet. It’s used by manufacturers, packaging suppliers and some large shippers who want proof that their pallets hold together in transport.

How the test works

The wrapped pallet is placed on a test platform, usually a sled on rails. The platform speeds up and then brakes to create a set pulling force on the load, like a vehicle stopping hard. Sensors and cameras measure how far the load leans and deforms while this happens, and whether it goes back into shape afterwards.

To pass, the load must meet three conditions:

While the force is applied, it mustn’t deform by more than 10% of its height.
Afterwards, it mustn’t stay out of shape by more than 5% of its height.
There must be no visible damage to the goods or the packaging.

Testing needs specialist equipment and is usually done by a small number of test centres. Results are specific to the exact load and wrapping pattern tested.

How it links to UK load security rules

On UK roads, the law says loads must be secured so they don’t move in a way that’s dangerous. The DVSA’s guidance on securing loads on HGVs and goods vehicles says a load securing system should be able to hold the full weight of the load forwards, and half of it backwards and to each side.

Straps, bars and the vehicle’s body do most of that work. But if the pallet itself falls apart, the straps are holding a pile of loose boxes. A stable, well-wrapped pallet is the first part of a secure load. That’s the part EUMOS 40509 checks.

Why it matters even without a test

Most businesses will never run a formal EUMOS test. The principle still applies to every pallet that leaves your site. A load that leans, shifts or bulges when it’s moved at the depot will do worse in the back of a lorry. Thinking about your pallets the way the test does is a useful habit, even informally.

What makes a load more stable

The things that help a pallet pass a stability test are the same things that help it arrive in one piece:

A tight, square stack, with heavy items at the bottom and nothing overhanging the pallet edges.
Three or four turns round the base, catching the pallet as well as the load.
Even tension all the way up, with each turn overlapping the last by about half.
Extra turns at the top to hold the top layer down.
Film that’s strong enough for the load. For heavy, tall or uneven loads, that usually means 23 micron.
Edge boards on sharp corners, so the film can be kept tight without tearing.
A top sheet or cap on loads that will be stacked or travel a long way.

Simple checks you can do yourself

You don’t need a test sled to spot an unstable pallet. Press the film on each side. Watch the load as a forklift lifts it and puts it down. Check that the film catches the pallet base all the way round. Our pallet load security checklist puts these checks on one printable page.

Who this is most relevant to

It matters most if you export, supply into automotive, food or retail supply chains with formal packaging requirements, or send tall or heavy loads long distances. It’s also worth knowing if you’re seeing more damage in transit than you’d like. Either way, the question is the same one every business wrapping pallets is already asking: is this load actually secure, or does it just look secure standing still?

FAQs

Is EUMOS 40509 a legal requirement in the UK?

No. It’s a voluntary test method. The legal requirement is that loads are secured safely, and some customers or contracts ask for EUMOS testing as proof.

Can I test my pallets myself?

Not to the formal standard, as it needs specialist equipment. But simple checks, like pressing the film and watching the load when it’s lifted, catch most problems.

Does thicker film always pass?

No. Stability depends on how the load is stacked, how the film is applied and how many turns are used, as well as the film itself. Thick film applied loosely can still fail.

What film do you recommend for long journeys?

For heavy or tall loads going a long way, 23 micron is the safer choice. Use black if the contents need to stay out of sight.

Our guide to wrapping pallets for shipping and export covers the wrapping technique in more detail. For loads that travel a long way, 23 micron clear pallet wrap is a good starting point, or black if the contents need to stay out of sight.
