EMC Testing Labs in Karlsruhe – Accredited Facilities

Nemko GmbH

Website →

Nemko GmbH is the German arm of the Norwegian certification group founded in 1933, operating for more than twenty-five years from Pfinztal-Soellingen in the Karlsruhe technology region and serving roughly 20,000 German customers under managing director Jahn Stephansen. The laboratory holds DAkkS accreditation to DIN EN ISO/IEC 17025:2018 under D-PL-22131-01-01, with a flexible scope that lets it apply revised editions of a test standard without prior notification, and the accredited scope is notably wide: electromagnetic compatibility including basic standards, product family standards and maritime equipment; telecommunications covering ETSI radio and short-range device testing; electrical equipment safety spanning household appliances, luminaires, safety transformers, IT equipment and measurement and control devices; and functional safety of products. EMC facilities comprise a shielded cabin, GTEM and TEM cells for compact emission and immunity work, and a 3 metre anechoic hall. Nemko is a recognised conformity assessment body for the Bundesnetzagentur, a notified body under the medical device rules, and a BAuA-listed GS mark test body; through the wider Nemko network of laboratories across Europe, Asia, North America, the Middle East and Africa it routes customers to FCC, ISED and Asian market approvals from the same project. Services extend beyond the chamber to electrical installation inspection, on-site operational safety testing, cyber security assurance and management system certification. Specialisations are international market access, household appliances and lighting, wireless and telecom products, medical devices, industrial machinery, and maritime and offshore equipment.

Siemens EMC-Center Erlangen and Type Test Center Karlsruhe

Website →

Siemens operates two DAkkS-accredited test centres under its Digital Enterprise Services banner, both accredited to DIN EN ISO/IEC 17025 and both open to external customers as well as internal product lines. The EMC-Center at Erlangen is organized into a Laboratory division and an Engineering division, the latter unusual in that it takes on field measurement, energy system simulation and on-site troubleshooting at customer installations rather than confining itself to chamber work. Its semi-anechoic chamber covers 150 kHz to 6 GHz for emission measurement with shielded cabins for immunity testing, and test programmes are run against IEC and EN standards, FCC requirements, the Korean KS C series, marine specifications and MIL-STD - a mix that reflects where Siemens equipment is sold. A particular strength is railway work: EMC and electromagnetic field measurement on rolling stock and on trackside and electrification infrastructure, including human exposure assessment. The Type Test Center at Karlsruhe complements this with environmental and mechanical qualification - climatic chambers of 600 to 1,500 litres covering minus 70 to plus 180 degrees Celsius and 10 to 98 per cent relative humidity, vibration to 100 g, shock, noise and drop testing - and carries a dense set of certification approvals: UL, FM, the IECEE CB Scheme, ATEX, IECEx, UKEX, CCC-Ex and marine type approvals, so explosion-protected and harsh-environment equipment can be qualified and certified in one place. Both centres offer test planning, approval consulting and EMC seminars. Specialisations are industrial and process automation equipment, railway vehicles and infrastructure, energy and switchgear systems, and explosion-protected apparatus.
