This section is drafted in accordance with the rules given in GB/1.1-2009.

This part replaces YC/T 10.2-2006 "General Technical Conditions for Tobacco Machinery Part 2. Cold Workpieces". With YC/T 10.2-Compared with 2006, the main technical changes except editorial changes are as follows.

--- "Terminology and definitions", the removal of "stamping parts", the addition of "flat stampings" and "formed stampings" (see 3.2, 3.3, 2006 edition) 3.2);

--- Increased the content of the board in the technical requirements (see 4.1.4);

--- Increased the content of stamping parts in the technical requirements [see 4.2.1b) 4), 4.2.1b) 5)];

--- Removed the dimensional tolerances, angular tolerances, shape and position of the stampings without tolerance, increased the unspun rule of the flat stampings Inch tolerance, unfilled dimensional tolerance of formed stampings, and blanking angles of flat stampings and formed stampings without tolerances, bending angles Unfilled tolerances, stampings shape and position without tolerances (see 4.2.2, 4.2.3, 4.2.4, 2006 edition 4.2.2);

---Modified the bending tolerance limit deviation level of stamping parts (see 4.2.5, 4.2.3 of 2006 edition);

--- Revised the verticality level of the punching plate [see 4.2.8a), 2006 edition of 4.2.6a)];

--- Increased the requirements for the use of die stamping parts (see 4.2.9);

--- Modified the bending radius of the curved pipe fittings (see 4.3.3, 4.3.3 of the 2006 edition);

--- Revised the angle deviation level of the curved pipe fittings (see 4.3.6, 4.3.6 of the 2006 edition);

---Modified component content (see 4.4.1, 4.4.3, 2006 version 4.4.1, 4.4.3);

--- Modified the tolerance level of the rivet hole of the composite member [see 4.4.4d), 4.4.4d) of the 2006 edition];

--- Increased the content of riveting misalignment (see 4.4.4f);

--- Added supplementary test content (see 5.2, 5.2 of 2006 edition).

This part is proposed by the National Tobacco Monopoly Bureau.

This part is under the jurisdiction of the National Tobacco Standardization Technical Committee Smoke Machine Subcommittee (SAC/TC144/SC3).
