Dear All,
Because I can't search any SPI standard contents to confirm the roughness.
Can any one tell me acceptance criteria ,if I apply the #400 grit paper to polish.
I think there are not specified roughness values in any standard as my application.
ex. #400 grit paper to polish, the approximate roughness values around 4~5 RMS in Wed side information.
Are there any positive #400 grit paper equal to 4~5 RMS on SPI or other standard.
