The Cpk formula for a one sided tolerance with a maximum (such as runout) is: (USL – Xbar)/ (3 * sigma) For a one sided tolerance with a minimum is: (Xbar – LSL)/ (3* sigma) where USL=Upper Spec Limit, LSL=Lower Spec Limit, and sigma is the estimated process standard deviation.

A one-sided tolerance interval example: For the example above, it may also be of interest to guarantee with probability (or 99 % confidence) that 90 % of the wafers have thicknesses less than an upper tolerance limit.

This problem falls under case (3). The first edition of this standard gave extensive tables of the factor k for one-sided and two-sided tolerance intervals when the mean is unknown but the standard deviation is known.

In this second edition of the standard those tables are omitted. Garaj, I. Janiga On?sided tolerance limits of normal distribution for unknown mean and. LET A = NORMAL TOLERANCE ONE SIDED LOWER LIMIT Y LET A = NORMAL TOLERANCE ONE SIDED UPPER LIMIT Y.

The facters are percentage points of the noncentral t-distribution, and as such can be used in designing certain acceptance sampling plans. One-Sided Limit or Two-Sided Interval Interval Type Specify whether the tolerance interval is two-sided or one-sided. A one-sided interval is usually called a tolerance bound rather than a tolerance interval because it only has one limit.

For the left-sided tolerance interval (X −kS,∞) we will also get P(t′≤k n)=1−α, where t′ has a distribution t (n,u n) ′−1 p and k is again given by (14).

We tabulate factors r and u, whose product equals K. Compact. Sample size tables are given for tolerance limits on a normal distribution. Wald-Wolfowitz two-sided limits and one-sided limits are considered.

The criterion used for determining sample size is as follows: For a tolerance limit such that Pr (coverage ≥ P) = γ, choose P′ > P and δ (small) and require Pr (coverage ≥ P′) ≤ by: About this Book Catalog Record Details. Tables of factors for one-sided tolerance limits for normal Owen, D.

These situations arise when a product characteristic need only meet a minimum specification limit or, remain below a maximum specification limit.

In this case, we would want to make use of a one-sided tolerance interval. The calculation of an approximate k factor for a one-sided tolerance interval comes from a formula described by Natrella ().
