GHT4184—2C02
This standard is the first revision of the national standard B1—1 for alloy wires: Compared with B414—1934, the following changes have been made: 1. Continuation of the title G/T1.11003 Standardization. 1. Preparation Unit 1: Standard Drafting and Expression See Rules Part 1: The basic requirements of the standard chrysanthemum wire have been increased.
2. The new name of the crane effect number has been added, and the brand number W-3R and its performance requirements have been added. 3. The use instructions of different types have been deleted. The explanation of the types has been added. The requirements for potassium content in the chemical composition have been increased. The minimum diameter has been removed from the specification: 3, and the diameter difference has been increased. The "heart atmosphere" deviation has been added: 7. The provisions for the short length of the alloy wire have been revised:
3, and the diameter compensation for the expansion control weakness has been made, and the tensile strength has also been reduced from the original. The value is changed to the standard; 9. The energy efficiency performance in the special inspection rules is changed to the tensile strength inspection, and the sampling plan (13/2828-2937 batch light sample number and sampling table (small reverse batch inspection) is used to replace the original sampling plan: 1). The tensile strength test method is added, and the viscosity of the machine is shortened to Appendix A511. The viscosity of the machine is added to Appendix B.
The date of implementation is the same as GB41841S24. The appendixes of this standard are the appendixes of the standard and the appendixes are reminders. Appendix.
