Some standard content:
The wood standard is revised according to the international standard 1554:1:2004 (English version) GR/T41392004. This standard is newly drafted based on 1805431:1980. In the attached A, there is a table of the number of the article in this standard: 15045-18U:1930. Considering the national conditions of my country, the 15045-18U standard is adopted. The vertical single-load mark is used in the margin of the page of the relevant model. The technical differences have been established in the B record for reference.
For the convenience of alignment, the following changes are made to TS5451:1: Change "This international standard is adopted as this standard" to "This standard"; replace the decimal point "15 (): 45:198" with the decimal point "", delete the first six digits of 180545:1980,
This standard replaces CB/T413-187-1987.
The main changes of this standard compared with 4139-137 As follows, two grades of FeV75-A and FV5-H in the standard are deleted, and two grades of FeVeU-A and FeVa5B are added. The FeV50-A and FeV5-B in the original standard are subdivided into FeV50-A, FVeA, HVB, and FeV6U-B: The requirements for chemical composition of products are modified:
The requirements for particle size of products are modified;
The requirements for the time and radiation of this comprehensive standard are for data recording. This standard is proposed by the China Iron and Steel Industry Association and the China Metallurgical Industry Information Standard Research Institute, and the drafting unit of this standard is responsible for the drafting of this standard. Pange Chemical Steel Supply (Group) Corporation, Metallurgical Industry Information Standard Research Institute, Pange Soft Alloy (Group) Co., Ltd.
This standard is issued by Lie Diguang, Ben Guisheng, Tan Kedi, Sun Minghui, Zhang Duanxiang, Liang Zhiquan, and the previous versions of the standard are as follows: YBr1-1965GH21391984, GB/413u-1U5..T

Technical differences between this standard and IS05451.1980 and their causes Table B.1 gives the technical differences between this standard and IS05451:1980 and their causes Table B.1 gives the technical differences between this standard and IS05451:1980 and their causes Table B.1 98D Technical Differences and Causes This standard's technical differences in the use of the current composite material as a sail element system to add the "replacement" for the needs and production of cutting Qin. It cites the main standard rather than the international standard, and the Chinese G4010.C/T8704.0:113247 is the same as the international standard, which makes the process "non-equivalent" in the country. It is difficult to standardize the national standard. Except for the 5 in 5451:1, except for the 3rd in [503451:120, the source is the international standard and the area is "common" and not completely gradual. According to my country's national conditions, 1S05451, 1984 area has used the measurement point and there is no continent. The standard of the unit solid degree is not applicable.
