TSC is a national standard management group (IS member body) of the industry. The development of international standards is also carried out through the IS. Each responsible party, if interested in a certain technical project, can join the committee with relevant non-governmental international production organizations. Under this item, it can have close contact with the International Working Committee (IEC) in the field of electrical standardization. The national standard reform adopted by our committee is The draft is distributed to all members for voting. The official publication of the international standard requires at least 7 votes.

Section: New digital mark: the inspection step and the continuous climbing performance of the highest (see Table 1). The nominal commercial value is 0.50.8, and the length is 3.0. The nominal guarantee is measured by the two-digit mark. The first digit indicates the monthly hardness test rate. The nominal guarantee should be 1/10 of the nominal guarantee in N/rm: The second digit "0\ indicates that the bearing capacity of the bolt and nut combination is smaller than the bearing capacity measured by the core, and the bearing capacity is smaller than the bearing capacity of the bolt-nut combination specified in Table 1.
