Hello, everyone. Let's come here to gether to discuss which standards we often use during daily work.

First, i am an inspector, i often check some welding and machining parts according to drawing. I probably use different inspection specification and codes in the different projects. but ASME, AWS , DIN and GB are often used during inspecting.especially DIN standard.

Second, my suppliers all don't know these inspection specification. so we have to bring content of these standards  to him and communicate with them to make them understand these. but sometime, we have to look for chinese standard to learn about these content and then correctly use them during inspecting. because inspection action have to have enough proof to state these situations.

Third, i often use ISO2768 part1- Tolerance for linear and angular dimensions without individual tolerance indications
                                          part2- Geometirical tolerance for features without individual tolerances indications
                           ISO 13920  Welding -- General tolerance for welded constructions--Dimensions for lengths and angles--shape and position

GB/T 1804-92  General tolerances—Tolerances for linear dimensions without individual tolerance indications

GB/T 1184       Genometrical tolerancing--Geometrical tolerances for features without lndividual tolerance lndications

GB/T 19804   Welding -- General tolerance for welded constructions--Dimensions for lengths and angles--shape and position

GB/T 15055-2007    Permissible stamping variations in dimenstions without tolerance indication

The above standards all are dimensions without tolerance indication.
