Process Information

UL verified the igus® chainflex® cable 36-month guarantee process, which covers the cables’ electrical and mechanical performances, and the process of calculating chainflex cable service life.

Designers can use the igus online service life calculator which is based on data that is yielded every year from 2 billion test cycles inside our 41,000-square-foot (3800m²) test lab in Cologne, Germany. The data is analyzed and aggregated into the calculator, allowing customers to easily enter their requirements and determine how long a selected cable is expected to last inside their moving application. The igus test lab has 800 tests running simultaneously and includes the following test capabilities:  
- 12 m/s² on 50 meters travel in an energy chain 
- Long Travel 400m travel test 
- 10 twister torsion tests 
- AutΩmes cable real time electrical function monitoring system 
- 2 x -40°C cooling chambers with continuous linear e-chain testing inside 
- Horizontal and vertical strokes 
- Circular movements of 720° 
- Rotation around robotic arms with 4 x 6 axis test robots 
- Raw material testing 

All chainflex® cables are designed by igus engineering and tested in the lab.  The 36-month guarantee, and service life calculator provides the customers with the confidence they need to be assured that their cables will function efficiently during the cables’ required lifetimes.

Verification Method

Verification of factory lab test process or processes including an audit of equipment calibration, testing personnel training records and procedural documents to confirm suitability for conducting moving applications cable (“robotic cable”) testing and confirm resultant data is used to support client’s “life time calculator”.

About the Company

igus® was founded inside Günter Blase’s garage in Cologne, Germany in 1964. He used his own injection molding machine to design a plastic valve cone as an alternative to metal. “Give me your most difficult part and I will find a solution,” Blase says. Today, igus® has expanded its product lines to include tribologically-optimized plastic plain bearings, linear bearings and slides, cables carriers, and continuous-flex cables. The company has locations in 35 countries (including the US), partners in another 80 countries, and employs 4,150 people worldwide. Our motto, “Plastics for longer life,” is rooted in Blase’s original goal to provide our customers with the right product at the lowest price as quickly as possible. We continuously make technical improvements to reduce maintenance and save our customers money. igus® developed its first chainflex® continuous-flex cable in 1989, making us the first in the wire and cable industry to develop a cable specifically for use inside cable carriers. The cables meet all RoHS II and REACH requirements as well as every standard in electromagnetic compatibility. They are certified according to UL, DNVGL, EAC, CTP and CE and are also approved and certified for use in systems according to EtherCAT, CC-Link, CC-Link IE Field, Profibus, Profinet and Interbus. More than 1,350 cable types, including bus, data, fiber optic, control and robotic cables, are available from stock and are guaranteed to last 36 months or 10 million cycles. igus® engineers continuously test each cable inside our 41,000-square-foot lab at our headquarters in Cologne, Germany – which is one of the largest test labs in the wire and cable industry – to provide customers with the highest level of predictable reliability. Over 2 billion test cycles, 1,561 production monitoring tests, and up to 1.4 million electrical measurements are carried out each year. igus® stores all of this data inside an online tool where customers can calculate the expected service life of their selected cables free of charge and without registering on our website.

What is UL Verification?

UL Verification is an objective, science-based assessment that confirms the accuracy of marketing claims. Our independent assessment process scrutinizes the validity of specific advertising or promotional statements, giving you a way to separate verified fact from fiction.
