Off-highway work lighting specialist TYRI has invested in an EMC laboratory in Gothenburg to measure how its products are affected by external interference factors such as power lines, cell towers or the electric environment of the vehicle.

When TYRI built the laboratory, the aim

was to measure whether its lights interfered with other electronic equipment on board a machine. However, the goal was always to be able to carry out all the tests needed to ensure complete electronic compatibility of the lights – both the impact the lights have on their environment and vice versa. That goal has now been achieved with the recent investments made. “There is a clear framework that needs to be met when developing new lights, but then we also have our own expectations of what our lights will cope with,” says Håkan Dalsvik, senior test engineer at TYRI. “With the equipment we had before, we were able to measure how our lamps affected the environment. But now we can also see how the lamps react to external stress. This can be anything from a power line hanging overhead, when there is a mobile mast nearby or other equipment on the vehicle


INDOORS FOR SUMMER Indoor winter testing is in full swing for UTAC CERAM Millbrook’s winter test facility in Ivalo, northern Finland. The winter season has come to a close, so testing has moved indoors and will continue throughout the year. Tyre and vehicle development work is conducted on its five indoor test tracks, all of which are powered by 100 per cent renewable wind energy. Now part of the UTAC CERAM group,

Millbrook Test World’s customers gain the benefit of all year testing as the group now boasts an even more comprehensive tyre testing capability. Test World’s year-round snow, ice and asphalt testing will be complemented by the UTAC CERAM Millbrook laboratory tests and soon-to-be opened proving ground in Morocco. The team has started ice grip testing for

the revised European tyre labelling regulation. The new ice grip symbol helps manufacturers to determine the suitability of their tyres in different, more extreme winter conditions. Test World’s expert team can accurately control the track

surface and air temperature to ensure stable conditions for this new test. The winter proving ground recently launched its new ASTM traction truck which enables customers to test winter tyres to the ASTM 1805 standard. Within its dedicated test lane, Test World uses an all- electric vehicle to improve set-up control. Jukka Antila, technical director at Test

World, said: “Using an electric vehicle helps us to control the test better. We are excited to be working with customers on

ASTM spin traction and ice grip testing, all whilst ensuring our facility is as safe and sustainable as possible.” Customers can send tyres directly to

Test World all year round for the highly experienced team to test on their behalf. This means that tyre manufacturers can continue their development programmes, without necessarily having to visit the
