Greeting Shazad,

There is a discussion of variables versus attributes sampling below at 02 Aug 2001.

> ...sampling plan for ... inspection?

Sampling plans contribute to inspection by enabling you to know 1) the risk of accepting an off-grade lot and 2) the risk of rejecting a good lot. Sampling plans can be very cost effective -- as the two kinds of erroneous decision can be very costly.

> ...fulfill our requirement?

Your requirement should be in terms of what (for you) are the acceptable and rejectable of quality. How to do this is explained at www.samplingplans.com/modern3.htm

> ...refer me to a sampling standard?

The best way to choose a sampling plan is with the software programs:

TP105 for attributes or

TP414 for variables

The software is described at www.samplingplans.com/software_oc.htm
