Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 15159-2008 "Precious Metals and Alloy Composite Strips". Compared with GB/T 15159-2008, except for editing
The main technical changes outside of the sexual modification are as follows.
---Modify "product classification", add surface convex compound and penetrating compound in compound method, and modify compound diagram (see 3.1.1, table 1,.2008
3.1.2 of the annual edition, Figure 2);
---Add noble metal IC-Ag99.99, Ag99.85Ni, Ag85Ni, AgCuP28-1, Ag95.5CuNiRE, Ag92.5
CuZnNiRE, Ag97Cu, Ag85Cu, Ag72Cu, Ag65CuZn, Ag45CuZn, Ag90SnO2/Ag, Ag88SnO2/
Ag, Ag85SnO2/Ag, Ag90SnO2In2O3/Ag, Ag88SnO2In2O3/Ag, Ag85SnO2In2O3/Ag, Ag35PdCu,
Ag49CuZnMnNi, Ag92.5CuNiCe, Ag92.5CuSnCe, IC-Au99.99, Au60Ag/Ag95.5CuNiRE,
30 pieces of Au10CuPdPtAgZn, AuNi5, AuNi9, AuPd20, Au/Ag, Ag40PdCuPt, Ag45Pd45Cu10
Grades; increase the base layer materials 4J29, 4J42, 4J50, Fe, N6, BZn18-20, H90, a total of 7 grades (see 3.1.2 and Table 2,
3.2.2 and Table 10 of the.2008 edition);
---The supply status has been increased from three to five, with the addition of extra hard state and 1/4 hard state (see 3.2, 3.1.4 of the.2008 edition);
---Adjust the delivery status representation method and increase the hardness value requirements (see Table 3);
--- Modify the total thickness, total width and allowable deviation requirements of the product (see 4.2.2, 3.3.1.1 of the.2008 edition);
--- Modify the product layer thickness and allowable deviation value and expression method, because the layer thickness range is related to the total thickness of the strip, so the layer
The thickness tolerance is a certain proportional value of the thickness of the composite layer (see 4.2.3, 3.3.1.2 of the.2008 edition);
---Modify the positioning measurement method, adjust the measurement position from the intermediate position to the combined position of the composite material and the base material (see 4.2.4,
3.3.1.3 of the.2008 version);
---Added the requirements and testing methods for side curvature of the strip (see 4.4 and 5.5);
---The method of measuring strip warpage has been added (see 4.5 and 5.6);
---Surface roughness is changed from Rz to Ra, the highest precision surface roughness Ra value is ≤0.1, and is not limited to multi-layer (see 4.6.1,
3.5 in.2008);
---Adjust the test method and judgment standard of the bonding firmness of the strip composite strip, the test position is adjusted from the middle of the precious metal to the precious metal and the base
The joint edge of the wood (see Appendix A, Appendix A of the.2008 edition).
