ISO/IEC 11801 is the most important international standard for structured cabling systems. It sets the basic requirements for the transmission parameters of structured cabling systems, their components and for the topology of the network's physical layer. Compliance with this standard is the requirement  and at the same time the guarantee of functionality of all standartized transmission protocols designated for information technologies.

Projects in which installed structured cabling meets the requirements of reaction to fire Euroclass B2_ca - s1, d1, a1 in accordance with applicable fire safety regulations of construction works and CPR.

From 1 July 2017 all cables used for construction works (e.g. buildings, roads, and bridges) in the EU must be clearly CE marked. Only cables with CE mark are allowed into the EU market. This is further specified in the CPR – the Construction Products Regulation (EU 305/2011). Why should cables be CE marked? Because electrical cables (incl. data cables and fiber cables) are permanently installed in construction works.

The recently introduced Construction Products Regulation (CPR) lays down harmonised rules for the marketing of construction products in the EU according to the product standard EN50575:2014. Starting from 1st of July 2017, every product must be CE marked and needs to have a Declaration of Performance (DoP).

What sets us apart. Ever since Gesellschaft für Hochfrequenzmesstechnik mbH was founded in 1992, we have been conducting in-depth analyses of passive network components. In 2000, ours was the first test laboratory in Europe to be awarded DIN EN ISO/IEC 17025 accreditation. Some of the world's best known companies in networking, as well as customers from the automotive, pharmaceutical and energy sectors, have relied on our industry-standard independent engineering services ("certified by GHMT") for more than 20 years. Big-name customers and engineers all over Europe now insist on GHMT certification.
