1 Encoding Rules for Surface Treatment Codes
A surface treatment code consists of a letter and three digits. The letter is specified by the first Chinese pinyin letter of the substrate material. This rule is not applied to the \sequential number.
2 Meanings Indicated by Surface Treatment Codes
Table 1 lists the process names, process definitions, quality standard document numbers, and OBSERVATIONAL STANDARD numbers. These quality standard documents and OBSERVATIONAL STANDARD s must be followed.
The treatments defined by the codes on the drawing must be performed according to the corresponding process and quality requirements listed in the table.
For details about OBSERVATIONAL STANDARD, see DKBA 0.400.0001.
The combination of codes on the drawing indicates that the surface treatments are performed one by one according to the sequence of the codes. This happens only in the following two cases:
1） Zinc electroplating followed by local powder coating (painting): The combination is \of zinc electroplating + code of powder coating on the steel substrate\(for example, G002+G108). The combination indicates zinc electroplating followed by powder coating. Note that phosphating involved in the powder coating process can be omitted.
2） Aluminum anodizing followed by local powder coating (painting): The combination is \anodizing + code of powder coating on the aluminum substrate\L001+L108). The combination indicates anodizing followed by powder coating. Note that chemical conversion involved in the powder coating process can be omitted.
3 Technical Description
3.1 Quality Requirements Indicated by Codes
As shown in Table 1, each code is followed by quality standard document number. The process indicated by the code must meet the quality requirements specified in the quality standard document.
YBxxx in Table 1 is the OBSERVATIONAL STANDARD number. For details about the OBSERVATIONAL STANDARD, see DKBA 0.400.0001 Specifications and Lists of OBSERVATIONAL STANDARD s. Each code that has a corresponding OBSERVATIONAL STANDARD number indicates that the object surface treated according to the process indicated by a code must be consistent with the surface of the corresponding OBSERVATIONAL STANDARD .
3.2 About Obsolete Codes
Table 2 lists the obsolete codes. If such codes are found on the drawing, the designer must change the surface treatment method.
