This part is modified to adopt 15011:79:2031 English version). The main modifications are as follows: 1) 1457S VI stipulates the requirements for packaging technology, and some of them are determined as follows (see Table 2): 15115 non-ferrous metals can be given a self-rest period of 4 years, and some are determined (see Table 2-151457% unspecified marking, this part is a simplified version of GB/T-237, and a simplified marking is given for reference only (see 5.2) This part replaces GB/T 6191—198 Hexagonal Medical Material Head Period-8, 3 and 10.9 level. This part is different from GB/16311986. The following are the main changes: --- The name of the standard has been added!
Added M2, M3.5, M3.M4, M5 (M_9) frequency effect specifications (see Table 1) Surface height effect (see Table):
Adjusted the original nail length (see Table 1): - stainless steel. Non-ferrous materials and their corresponding properties (see Table 2) Added magnetic materials and grade 2 (see Table:
Added "non-electric zinc sheet coating" (see Table 2: Quality considerations for steel ladle) || tt||The Appendix A of the woodworking section is the material appendix.
This part is proposed by the China Machinery Industry Federation: This part is sponsored by the National Technical Requirements for Standardization Committee (A\), and this part is sponsored by the China Academy of Mechanical Engineering: The latest version of the standard replaced by this part is: GR/T2671:198*
