Step Inside Lapp Group’s Laboratory

Cable automation

Lapp Group provides high quality products, services and customer care in order to ensure you are getting the best value for money possible. When it comes down to the products themselves, hard work and determination to provide the highest of quality around is at the forefront of everybody’s minds.

At Lapp Group, every product is tested behind closed doors for everyday suitability. Products such as cable assemblies, cable glands and connectors go through rigorous testing procedures to ensure the end user is getting a reliable and robust product.

Testing can take a couple days, but can also take years if cables need to be tested for ageing properties. Can you artificially age a cable in a laboratory? The answer is yes, by placing it in a heating cabinet that can simulate many months in a matter of days.

Up to 40 different tests are performed on a single cable, depending on where the product itself will be used. If the location happens to be an oil platform, then drilling mud from Scandinavia will also sometime be used.

An example of what testing is required is the procedures followed prior to the launch of the SKINTOP Hygienic in November 2014. For this product is was absolutely necessary to monitor construction and measures, check the threads, test for anti-twist protection, check strain relief and ensure that the connector is watertight and dust-proof, amongst other things.

A negative pressure is produced for 8 hours at a time and talcum powder is added. At the end there cannot be one single speck of dust. Only then does the product pass the test. This is not the only type of testing done however, as at other stations the cable, connectors and cable glands are tested for chemical resistance.

This is where material tests take place through long test phases such as the ECOLAB test, which takes four weeks. ECOLAB is a leader in the area of industrial cleaning products for hotels, restaurants, hospitals and of course food manufacturers, as well as breweries.

These environments typically use chemicals to clean machinery. Achieving this certification proves that the products that have gone through the testing are resistant to these cleaning agents and disinfectants.

What exactly happens during ECOLAB testing? In order to achieve this certification, products are fully immersed in 6 different test solutions for 28 days. They are visually monitored every 2 days: for soaked or brittle surfaces, colour changes and defects such as cracks. If no tags are visible after 4 weeks and the products pass the following functional tests, the product can be officially classed as resistant.
