Recently, the international standard proposal "Wire Rod for Bridge Cable Steel Wire" (ISO/NP 6819) led by ZXTG Special Steel Technology Group was officially approved by the International Organization for Standardization (ISO). This is the first international standard project successfully established by ZXTG, which has greatly enhanced the company's right to speak in international standards, and at the same time marked a significant progress in China's participation in international standardization work in the field of bridge steel wire.
ISO/NP 6819 is drafted by experts from ZXTG and the Metallurgical Industry Information Standards Institute as the project leader, and British experts as the project convener. Under the active promotion of the ISO/TC17/SC17 secretariat and the joint efforts of the ZXTG standard team, after full preparations, this international standard has received high attention during the project voting stage, and has won from the United Kingdom, Japan, Belgium, Italy, and Poland. Extensive support and participation of experts from other countries.
As the key and control unit of the road system, bridges play an important role in modern transportation. With the rapid development of the world economy and the progress of bridge construction technology, the world's bridges are gradually developing in the direction of large span, large load, long life, and low wind resistance. The demand for bridge construction is increasing, and there is an urgent need to develop ultra-high-strength bridge cables. Use steel. The drafting of this international standard provides technical support for the global production and trade of wire rods for high-strength cable wires.
The ZXTG and ISO/TC17/SC17 secretariats will strictly follow the ISO working procedures and requirements, join experts and representatives from various countries to join the standard working group, accelerate the development of standard research and preparation, and contribute to the international standardization work in the field of bridge and cable steel.
