TECHLINE testing programme - masters the details

At LINAK®, we specialise in supplying customised products and designs that function
perfectly at all times. To ensure that this is in fact the case, each component in ouractuators is subjected to comprehensive tests at our test centre where nothing is left tochance.
Our actuators must perform every time, no matter whether the actuator concerned isdesigned to guide corn through the unloading auger on a combine harvester during
peak season, or it needs to perform in harsh and salty environments on a yacht. This is
why - long before they come anywhere near a customer - we subject them to several
tests.

“Our actuators must never malfunction.
Therefore, it is important that all ourproducts are tested inside and out, andto the extreme in a wide range of tests.”- Claus H. Sørensen, Director R&D

At our test centre, a handful of development engineers perform a wide range of tests
at the design and product development phases for each individual type of actuator.
However, this does not mean that we only test prototype actuators during the designphase and when they are fitted. It is very simple: we subject each tiny component
that will be used in our designs, because we believe that testing is not only a matterof making sure that the products function perfectly. It is also about maintaining ourcustomers’ confidence in the standards to which we test.
Therefore, it is important that all our products have been tested inside and out, andto the extreme in a range of tests that include twisting, vibration and shock, chemicalbaths, salt vapours, water spray and severe high and low temperatures for days, weeks,months and years on end. This way, we can ensure that our products comply with - andeven exceed - all strict requirements that our customers and we expect of them.

Please note:
LINAK offers a range of third party products
compatible with our TECHLINE actuators.
Most third party products are
not subject to the extensive test
programme mentioned in thisbrochure.

Performance testing

Durability
The bearings are tested for durability, rotation, pull and push. In
our test centre all actuators regardless of size are subjected tomechanical testing. The largest test bench, is 4 m high and canpush or pull a load of up to 5 tons.
It is used for safety factor tests, and here the actuators are subjected
to continous static pull and push combined with torsion until theydisintegrate. As a rule of thumb, the actuators must be able to withstand a load of at least 2 times the rated maximum nominal load.

LINAK® industrial actuators must perform in dynamic and challenging
environments. In our test centre we subject the actuators to both
vibrations, shock/bump and drop tests. The actuators are tested towithstand constant vibrations from three directions and 50 G shockwaves from six different directions.
The drop test ensures that, despite having visible external damage,the internal components must be in perfect working order whendismantled after the test.

IP ratings
To ensure the highest possible Ingress Protection (IP), we test theactuators for both fluid and dust ingress.
We test the actuator enclosures for watertightness in a speciallydesigned water spray test rig, according to IPX6.
For applications demanding high-pressure cleaning, we recommend
actuators with IP69K rating. Here, the actuator must withstand a highpressure spray of hot water without any water ingress.

Salt and chemical vapour
The actuator is exposed to the adverse effects of e.g. salt vapours,
chemical substances, diesel oil, hydraulic fluid, nitrogen, inorganic
fertilizers and agricultural lime. All these substances affect both theplastic and metal parts of the actuators, which means that we have tocreate very harsh test environments. The actuators are exposed to ahumid environment with high concentrations of e.g. chemical vapoursor concentrated salt vapours for up to 12 months.

Climatic testing

Temperature fluctuations
We test our actuators in a sealed environment for periods up to10 months, where both the temperature and the humidity is cycled
between -55°C to 105° and up to 100% relative humidity. Many
test patterns are performed to ensure that the actuators will survive
all climatic conditions according to the specific applications. Most
climatic test are performed according to recognized norms andstandards. Based on our many years of experience we have designed
special test patterns to ensure that very demanding applications arealso covered in our test plan.

Cables, plastic, and composite components are tested to fulfill sun
and weather ageing. Our UV test chamber is capable of performing
an accelerated UV test according to a specific standard or according
to actual customer demands.
By performing both the temperature, humidity, IP and UV tests weensure that our actuators always perform in dynamic and harshenvironments. This is why we emphasize that you can rely on youractuator.
