What is the formula for calculating the d2* factor for the actual K1 number in the EV calculation. I have the chart from the MSA book that has the m & g values but the chart only goes to 20 and I need to know what it would be for g = 30 (3 operators and 10 samples).

Only if the absence of a maintenance program adversely affects product quality.
To answer this question for yourself, analyze the system you already use to run your business then see actions 1 and 2 or 3 and 4 below.
1. Does it include a maintenance program?
2. If it does then include this in your quality management system.
3. If it does not then seek evidence of any product quality problems.
4. If the absence of a maintenance program affects product quality then work with your maintenance manager to design and implement a new process. Document this process to the extent necessary for its effective planning, operation and control (see 4.2.1d).
