This part replaces YC/T 10.10-2006 "General Technical Conditions for Tobacco Machinery Part 10. Metal Plating and Chemical Treatment", and Compared with YC/T 10.10-2006, the main technical changes except editorial changes are as follows.

--- Revised the representation of metal plating and the marking requirements on the drawings (see Appendix B, Appendix B of the 2006 edition);

--- Revised the quality requirements of the parts to be plated (see 3.4.1, 3.4.1 of the 2006 version);

---Modified the requirements of the zero (part) parts and springs after grinding or flaw detection (see 3.4.2, 2006 edition) 3.4.2);

--- Increased the requirements for the plating of zero (part) parts after heat treatment (see 3.4.3);

--- Increased the requirements before welding of welded parts (see 3.4.4);

--- Revised the surface quality requirements of the zero (part) parts after sand blasting (see 3.4.6, 3.4.5 of the 2006 edition);

--- Revised the requirements for different parts of the plating type (see 3.4.9, 3.4.8 of the 2006 version);

--- Revised the quality requirements of galvanizing, copper plating, nickel plating, hard chrome plating (see 3.5.1~3.5.4, 3.5.6, 3.5.8~3.5.10, 2006 edition) 3.5.1~3.5.4, 3.5.6, 3.5.8~3.5.10);

--- Increased the quality requirements of two common plating treatments of "metal thermal spraying" and "steel ceramics" (see 3.5.11, 3.5.12);

---Modified the content of the detection method for different plating treatments (see 4.4, 4.4 of 2006 edition);

--- Revised the thickness and hardness test rules (see 5.2, 5.4, 2006 editions 5.2, 5.4);

--- Revised the standard metal standard electrode potential (see Table A.3 in Appendix A, Table A.3 in 2006).
