This standard specifies the general dimens ional tolerance in length of the plastic
part for automobiles (hereinafter referred to as the general tolerance">
Remark: In specifications and drawings, when the function of the item does not require
special accuracy on its dimens ions, the general tolerances shall be indicated
col lect ively without bein& written in each dimension
