[Ma...] Posted September 16, 2022 Share Posted September 16, 2022 I have no clue - usualy it will be capital letter i or number 1. I found only mentions about number of decimal places - aka in tenths ( 0,1mm ) but i am not sure. I would ignore it 🤣 Link to comment https://qualityforum.zeiss.com/topic/9534-iso-designation/#findComment-44436 Share on other sites More sharing options...
[Da...] Posted September 16, 2022 Share Posted September 16, 2022 That’s the symbol for the Independency Principle, which is odd, because in ISO it’s the default anyway. I’m not even sure if this symbol exists in ISO. So basically it means: Don’t use the Rule #1 from ASME.
