chainflex® – meeting cable standards around the world

More safety for people and the environment
The abbreviation RoHS stands for Restriction of Hazardous Substances and regulates the use of selected hazardous substances in electrical and electronic equipment, including cables. By complying with this guideline, companies demonstrate that problematic constituents, such as e.g. lead, mercury or phthalates known as plasticizers - have been banned from electronic waste but also from working environments. One example is lead. It occurs in production systems in the form of tin solder on circuit boards, which are built into complex machine systems in a variety of ways. In recent years, materials research has also produced new jacket materials which do not require hazardous plasticizers and thus function flexibly in dynamic applications. Until now, plasticisers have been used in industry mainly where plastics had to remain particularly pliable, soft and elastic in use. igus® develops and tests special jacket materials for use in e-chains in its own laboratory that are RoHS II/III compliant.

Like CE marking for the EU zone, UKCA marking ("United Kingdom Conformity Assessed") is a marking requirement for certain technical products.
In doing so, the manufacturer declares that the products are manufactured in accordance with applicable directives or the "United Kingdom" regulations.
UKCA marking is not a seal of approval or sign of quality and was created for trade with the "United Kingdom".
Technical details or further regulations on this are still being developed by the UK government and professional associations.
As a result of the national development of product regulations, it is possible that there will be product requirements that differ from those of the EU and must be complied with by manufacturers and importers wishing to place products on the market in the United Kingdom.

The chainflex® guarantee assumes the operating conditions are applicable for the respective cable group. These conditions consist of parameters such as temperature, movement type, torsion, media influence and bend radius.
Your guarantee will cover up to 4 years or ten million double strokes (for cables of the chainflex® 800 family, up to five million double strokes, and for high-end-type cables, up to 40 million double strokes), whichever comes first. The number of double strokes covered by the guarantee depends on the type of installation and the cable quality. These factors are described in the current catalogue, the data sheets and the service life calculator.

We issue a guarantee of up to 4 years on our cables with confidence, as we are able to make reliable predictions about the service life of our cables due to over 30 years of experience and 700 experiments concurrently undertaken in our 3,800m² test laboratory.

The maritime economy is developing towards more automation and digitalisation: whether vessel manufacture, shipping companies or the gas and oil industry - ships are becoming autonomous factories, shipping companies are becoming fully-fledged logistics providers and refineries are becoming automated conveyor systems. DNV-GL is responsible for certifications in the maritime environment, offshore facilities, gas and oil pipelines, and onshore applications such as wind, tidal or solar energy. The classification society was formed in 2012 through the merger of the Norwegian company Det Norske Veritas (DNV) and Germanischer Lloyd (GL). The components used in maritime environments have to meet different requirements than those of classic factory automation on land. This requires a separate approval for the operation of these components. The certification society checks compliance with international standards and guidelines, which are applied accordingly to these components. If existing regulations or standards do not describe the application sufficiently, additional testing measures are defined or developed. If products have DNV approval, it simplifies and speeds up their use in the maritime sector, as it is not necessary to test individual components.

DEcentralised and Standardised INstAllation technology is a recommendation of the German Machine Tool Builders' Association (VDW) for the standardisation of components, interfaces and connection systems. DESINA describes a comprehensive overall concept for the standardisation
and decentralisation of the fluid and electrical installation of machines and systems.

A cleanroom is an enclosure that is essential for sensitive products. This are necessary in industries such as semiconductor production or in medical technology. In these rooms the air is cleaned of the smallest particles. For this purpose there is a classification, which describes how many particles per m³ volume may be in the room.

A cleanroom certificate states how many particles are emitted by a product into the ambient air during normal operation. In this case, the fewer the particles, the higher is the quality of the product. For cables, igus® collaborates with the IPA Institute, where the components are tested for this release in standardised motion sequences in an e-chain® and there is a clear statement on the purity class.
