IEC 60445 / IEC 60446 - Conductor identification and pin assignment
What does the standard regulate?
These standards regulate the color coding and symbols of electrical conductors - for DC and AC circuits, protective conductors, etc.
Why is it important?
Standardized colors and symbols minimize misconnections, facilitate maintenance and are required for CE/UL approvals.
IEC 60112 - tracking resistance of insulating materials
What does the standard regulate?
It describes the method for measuring the Comparative Tracking Index (CTI), i.e. the dielectric strength of insulating materials in damp or contaminated conditions.
Why is it important?
Leakage current can cause failures or fires - tested CTI values safeguard the choice of insulating material against such risks.

What does the standard regulate?
CE and ENEC 16 are markings for products that comply with the basic safety requirements of the EU directives.
Why is it important?
It is mandatory for the free movement of goods in Europe and confirms minimum legal standards - also vis-à-vis customers and authorities.
VDE - German electrical engineering standards
What does the standard regulate?
VDE standards define binding standards for electrical safety, EMC, installation and testing technology in Germany and the EU.
Why is it important?
Products with VDE certification signal high quality and are often preferred in public and industrial procurement.
UL-compliant - US-compliant product approval
What does the standard regulate?
"UL compliant" means that a product meets the requirements of UL standards - whether through file listing or the use of an approved insulation system.
Why is it important?
UL compliance is essential for products sold or installed in North America - often a mandatory requirement.
EN 61000-6-2 / -6-3 / -6-4 - Emission & immunity
What does the standard regulate?
These EMC standards regulate the limit values for conducted and field-bound interference as well as the interference immunity of industrial electrical systems.
Why is it important?
Only EMC-compliant systems are safe to operate, cause no interference and meet statutory CE requirements.
EN 55011 / EN 55032 - Radio interference in industrial/multimedia applications
What does the standard regulate?
These standards define electromagnetic emission limits for industrial equipment (EN 55011) and multimedia/IT products (EN 55032).
Why is it important?
It is a prerequisite for CE marking in Europe - and important for ensuring radio compatibility.
EN 61000-3-2 / -3-3 - System perturbations (harmonics)
What does the standard regulate?
The standards regulate system perturbations such as voltage distortions (harmonics) and voltage dips that electrical devices may cause.
Why is it important?
They ensure stable power quality and are a prerequisite for the CE marking of grid-connected devices.
EN 50581 - RoHS documentation
What does the standard regulate?
