Screen a packaged-goods sample using the declared nominal quantity and the applicable tolerable negative error entered by the user.
Enter the nominal quantity, the applicable TNE, sample average, minimum observed pack and sample count below one TNE. This provides a transparent screening result; it does not replace the statutory sampling method or competent legal-metrology advice.
The applicable tolerable negative error depends on the nominal quantity and legal framework; entering it avoids silently assuming the wrong band.
It checks whether the average meets nominal and whether the minimum is below two TNE; it reports the entered count below one TNE for review.
Packs below twice the TNE are not permitted, while the permitted number below one TNE depends on the sampling regime.
Keep the measurement method, equipment checks, sample results, production batch and corrective actions required by the applicable system.
