Drawing description
Unless otherwise stated, the dimensions and tolerance in the drawings are the final dimensions and tolerance for spare parts or with are key dimensions, and they should be well ensured during manufacturing. For dimensions only signed with
Dimensions with () are reference dimensions, that are used in closed loop in dimensioning chain, and its value is for reference only. Reference size sample shown in Figure 4. ? Reference dimension
Level 1 sueface
The surface marked with level 1 surface on the drawing (as shown in 5) is appearance
surface, It means that there is a higher quality requirement of the surface appearance, the quality of surface appearance of these parts must meet appropriate requirement (specific requirements
are described detailedly in product quality specification, or in process quality specification,or in
drawings)
? Level 1 surface description
? Riveted part marked
? Rivet Fastener Legend
? Welding symbols marked
see the DKBA04000139 (Quality Requirements for Welding)
? Fastener material and surface treatment marked
It to distinguish the different materials and surface treatment is by the letters which followed by the name of the fastener,and the defaulf material is is the meaning of each letters:
_S：the material is stainless steel _Cu：the material is brass _Al：the material is aluminum
_ZC：Zinc electroplating with yellow conversion coating _H：Zinc electroplating with back conversion coating _N：Electroplating nickel
_ZnNi：Electroplating Zinc- nickel alloy _ZnAl：Zn-Al Flake Coating
Example:
GB5783-2000_M10x135_S meanings stainless steel hex bolts
GB5783-2000_M10x135_S_ZnAl meanings stainless steel hex bolts with Zn-Al Flake Coating.
The rivet without suffix dafect to aluminium rivet,and the strength grade is Lever 10, if with suffix _s means the material of rivet collar and bar are austenite stainless steeel.
