Sampling scheme

[Former Member]

Gurus,

What does this msg mean?

Diagnosis

A sampling procedure was assigned to a characteristic in the inspection plan that references sampling scheme 10.

In this sampling scheme, no entry (that is, no sampling instruction) was found for the inspection severity 004, the AQL value 0.000 and for the lot size (for the population) 5000100.

Keep in mind that the population is not necessarily the same as the lot size. The population is calculated from

the lot size

the conversion factor of the base unit of measure in the sample unit of measure

the factor of the sample unit

Example:

Base unit of measure is kg and the sample unit of measure is gr. The conversion factor is 1000. The factor of the sample unit is 5. As a result the individual sample is 5 grams.

If the lot size is, for example, 20 kg, then the population to which the sampling scheme is applied is 4000 (20 * 1000 / 5). If the calculated population exceeds the maximum allowed value of 10,000,000,000, the maximum value is used if it is entered in the "Lot size" column in the sampling scheme.

Procedure

Maintain sampling scheme 10.

This maens you have used sampling scheme 10 in sampling procedure which has severity 004, the AQL value 0.000 .

When lot size is 5000100 system do not find relevent sample size in sampling scheme.

So solution is to mainatin the sampling scheme preperloy & also mesion the maximum allowed lot size in the sampling table (10,000,000,000).

HI,

I have entered the max value,now it is calculating perfectly.
