[Pharma] Standard data set to validate Excel spreadsheet calculating Cpk, Ppk

I am planning to create an Excel spreadsheet to calculate Cpk and Ppk. As my company do not have budget to buy off-the-shelf solutions (Minitab, JMP, SAS...) to calculate these indices, we want to use Excel. The only concern is to find a standard data set to check if the calculation is correct or not. I heard someone mentions about the ISO standard data set but I have not been able to find it online.

Thank you

See the Ford validation data set for Gage R&R and for Cpk/Ppk in post #1 of this thread.
