Crash tests and standards.
The French institute for work related accidents, INRS, mandates the toughest ever standard for crashtesting van interiors. The standard mandates a higher collision speed and much more stringent values for interior payload weight than have previously been used. In June, System Edström had the independent test institute Valutec perform a crash test according to INRS NS286.
“We were quite certain that we would pass the test”, says Linus Runhede, Design Engineer at Edström. “But I can’t deny that I had some butterflies in my stomach when we saw the test sled coming in over 50 km/h (31 mph). And it certainly was a loud and violent impact! “
“We could see that the interior hadn’t moved much and that all the payloads stayed where they should have been, but it still was a relief when we heard the words from the test guys: C’est une bonne, It’s good; It’s OK!
INRS is a big (700 employees) institute which continuously develops the area of occupational risk prevention. The norm NS286 states an impact of at least 25 G and has strictly regulated sizes and weights for payloads in shelves and drawers. The interior has to be mounted according to normal installation instructions. All test institutes agree that NS286 is going to become the common standard for interiors, as the NCAP is for cars.
“Another scary thing with NS286 is that all the payloads have to be 80% of the length of the shelves”, Linus continues. “That means that there is actually another impact from behind, a few milliseconds after the first impact. The interior managed both hits very well and it is very satisfying to confirm that we have been thinking, and constructing, in the right direction!”
Passing the test will mean a lot to System Edström in all markets; safety is a big factor everywhere nowadays, and for the French market it also means that our customers will enjoy lower insurance fees!

System Edström Van Interior Pass Punishing Crash Test - With full marks.
System Edstrom Van Interior, racking and shelving systems have achieved excellent results in a recent vehicle crash simulation, proving that for safety as well as versatility the company is hard to beat. The tests are believed to be the first time a manufacturer of van interiors and LCV accessories has subjected its products to this most severe of test methods.
Tests at independent vehicle test and development facility Millbrook in Bedfordshire England, were carried out on a new van fitted with System Edstrom van interior including shelving, drawers, roof rack and accessories. Bulkhead safety partitions were also put through their paces.

The company sought extensive advice before opting for a recognised EC test method that simulates severe impact. The test piece, in this case the van and its fittings, was subjected to an impact curve peaking rapidly to a punishing 20 G-force. During the tests, some components were subjected to even higher loads with ranges as great as 40 G!! The resultant 'pulse' is equivalent to a head-on impact with a solid stationary object or two vehicles crashing at 30 mph. The van interior system and roof rack were loaded with fixed weights to simulate the payload.
Millbrook engineers confirm, "The test was performed using an acceleration pulse that conformed to the displacement of luggage test for ECE R17.07. The racking system, mobile workshop, roof rack and associated accessories were successfully retained."
The System Edstrom products proved their structural integrity with little evidence of failure. The system was intact and remained fixed to its original mountings on the floor and walls of the van. The drawers did not lose their contents. Most importantly, nothing encroached into the driver's cab area.
The tests were witnessed by representatives from the Vehicle Certification Agency (VCA); the UK’s national approval authority for new road vehicles, agricultural tractors and off-road vehicles; a leading motor manufacturer and the full Millbrook test laboratory staff.
