Product Standard and Certificates
新建网页 1



Standards and certificates are worldwide established standards for electrical products to support their quality, safety and compatibility with each other. CE, DIN, EN ...many tokens of the most common standards may have been encountered by you. On this site you will learn more about them and what the stand for.

The CE marking is a EU wide regulated certification mark for product sefety. By issuing the logo and a corresponding number the manufacturer or EU-importer takes responsibility to fulfill several safety instructions.



DIN stands for "Deutsches Institut für Normung". It operates on behalf of interest groups like different companies to achieve e.g. technical standards. A very common example is the paper format DIN A4 which is known all over the world. It is derived by DIN476.



EN are regulations on EU scale. They are issued by three european committees for standardisation and ratified by them. The are obligatory defaults for national standards. In Germany these regulations are published as DIN-EN-standards.



The Federal Communications Commission (FCC) is an US-admission board for communications. It is checking the devices like radios, TVs and computer to be compliant to it´s own and other standards. One of the well known FCC regulations is the RJ-45.
A standard for modular plugs and sockets.



The International Organization for Standardization is a global coalition of regulation entities. It is developing international standards exept electronics, electrics and telecom.



The european guidelines of RoHS (Restriction of the use of certain hazardous substances) regulates the use of poisonous or hardly degradable substances within devices and parts. Especially, but not limited to:

  • lead
  • mercury
  • cadmium
  • hexavalent chromium
  • polychlorinated biphenyls  (PBB)
  • polybrominated diphenyl ethers (PBDE)


The "TÜV" (Technischer Überwachungs-Verein) is know in Germany for it´s car exhaust analysis. But the services of the TÜV reach far beyond that. The "TÜV CERT -Zertifizierungsgemeinschaft e.V." checks producs from all spheres of life and also whole companies to comply to international and EU regulations. The INTOS ELECTRONIC AG (Manufacturer of the InLine product line) is certified to be compliant to DIN EN ISO 9001 : 2008 This standard defines requirements to the management system by the following criteria:

Customer focus:

  • Responsibility of the leadership
  • Inclusion of involved persons
  • Process driven approach
  • System oriented management approach
  • Continious enhancement
  • Objective decision-making approach
  • Supplier relationships for mutual benefit


Besides the CE label the german GS seal is the only statutory certification mark for product safety in europe. It testifies the products safety to the user compliant to the "Geräte- und Produktsicherheitsgesetz (GPSG)". The specific requirements can be found withinDIN- and EN- regulations and are, of course, also a scale for all safety sensitive products of the InLine product range, like power strips and extensions.



High Definition Multimedia Interface (HDMI) defines not only a well known audio and video interface but also an international technological standard. A HDMI forum, founded and run by many different independent companies and entities monitors the guideline compliance of the manufacturers and drives the constant technological enhancement of the standard.



The International Electrotechnical Commission - IEC is an international standardization body within electronics and electrics.



The Institute of Electrical and Electronics Engineers (IEEE) supports the standardisation of technologies of hard- and software. One of the most popular standards of this organisation is the „IEEE1394“ – or better know as the computer interface „Firewire“.



Underwriters Laboratories (UL) is an independant US organisation which checks and certifies products in regard to their safety. For EU products the UL certification is not mandatory, but to export products from the EU market to the US market it is of great importance. Many InLine products are compliant to this standard as well.



Similar to HDMI the well known USB port is also a technological standard. The USB standard is developed by a consortium of autonomous companies like HP, Intel and Microsoft, which are presenting, maintaining and defining guidelines for data rates, cables and plugs.



The VESA (Video Electronics Standards Association) is one of the largest industrial standardization entities. It is enforcing common standards for video, especially computer graphics. Within the last few years it has become synonymous for the flat screen mounts.



The WEEE-Guideline (Waste of Electrical and Electronic Equipment; tries to enlarge the manufacturers responsibility to reduce the production of electronic waste. This way it tries to minimize the amount of enviromental dangerous electronic devices and also tries to enforce a professional recycling.
