2017 Honda Ridgeline. The Honda Ridgeline is a unique pickup that employs car-like unibody construction in place of the rugged but unrefined body-on-frame setup that underpins its competitors. As a result, the Ridgeline provides a more comfortable ride and better handling than most pickups while still offering decent towing and hauling capabilities.
The flatness tolerance references two parallel planes (parallel to the surface that it is called out on) that define a zone where the entire reference surface must lie. Flatness tolerance is always less than the dimensional tolerance associated with it. Tolerance Zone: Two Sets of Parallel Planes where the entire referenced surface must lie. Gauging / Measurement: Flatness is can be measured using a height gauge run across the surface of the part if only the reference feature is held parallel.
Two-sided Tolerance intervals are calculated as: (1). Where is the sample mean; s is the sample standard deviation; and k2 is a factor for a two-sided tolerance interval defining the number of sample standard deviations required to cover the desired proportion of the population.Exact values of k2 are tabularized in ISO 16269-6.here: n is the sample size; Z1-p/2 is the standard normal variate corresponding to one minus the proportion of the population to be covered divided by two. is the critical value of the chi-square distribution with n-1 degrees of freedom surpassed with probability g, the statistical confidence.
