Standards and testing

Tests

Siemens surge arresters have been designed and tested in compliance with the latest IEC 60099-4, IEEE C62.11, and GB 11032 standards. All type tests are performed by independent, PEHLA- certified laboratories; reports are avail- able on request. Please contact your Siemens representative for details. Moreover, every single surge arrester that leaves the Siemens factory undergoes a routine test and is delivered with a routine test certificate.

Quality assurance

Siemens meets all requirements of ISO 9001:2008, ISO 14002:2004, and BS OHSAS 18001:2007. All Siemens suppliers need to be certified according to ISO standards or will be audited by Siemens. To maintain sustainable quality improvement, Siemens introduced corporate quality guidelines that contribute to each step of the quality process.

Standardization

The aim of the IEC’s Technical Committee 37 (TC 37) as well as the IEEE’s Surge Protective Device Committee (SPDC) is the standardization of surge arrester testing and application. The TC 37 develops the standards IEC 60099-4, IEC 60099-8 (EGLA), IEC 60099-9 (HVDC), and the application guide IEC 60099-5, while the SPDC develops the standard IEEE C62.11 and the application guide IEEE C62.22. Both committees include representatives of manufacturers, utilities, test field labs, and universities. Siemens R&D experts are members of both bodies, thus playing an important role in the definition of the standards. They also share their expert knowledge in electrical power systems in CIGRE, the international council on large electric systems, which participates in the development of international standards.
