IEC 62271-203:2003. High-voltage switchgear and controlgear - Part 203: Gas-insulated metal-enclosed switchgear for rated voltages above 52 kV

This European Standard was approved by CEN on 8 November 1998. Amendment A1:2000 was approved by CEN on 20 April 2001. 12p. This part of this European Standard specifies the technical delivery conditions of the types of forgings for pressure purposes, made of weldable fine-grain steels with high proof strength.

This European Standard was approved by CEN on 13 December 2008. 10p. This European Standard specifies the requirements for the mass, other properties and testing of non-ferrous metal coatings on steel wire and steel wire products of circular or other cross-section

This European Standard was approved by CEN on 28 February 2003. 24p. This part of this European Standard specifies the technical delivery conditions for seamless cold drawn steel tubes of circular cross section used in hydraulic and pneumatic power systems.

This European Standard was approved by CEN on 24 July 2003. 36p. This Part of this European Standard specifies a concise procedure for conducting thermal performance tests, using the indirect (losses) procedure for boilers for steam or hot water. Test results are based on either the gross or net calorific value of the fuel.

2 страницы SPD/TVSS Changes Effective September 29, 2009 UL 1449 has undergone extensive revision as surge suppression’s standard for safety. UL 1449 Third Edition, defines performance testing and nomenclature, which effectively reboots the surge industry. UL 1449’s performance testing provides a way to compare newly evaluated Surge Protective Devices (SPDs), formerly known as Transient Voltage Surge Suppressors (TVSS). These changes became effec...
