The following guide shows the nominal weight of 150g - 500g the TNE1 is 9g so the approved division (e) should be 0.2 of TNE1 = 1.8g, and the nearest digital unit would be 1g (e) trade Approved.
The sampling methods you are using must be sufficiently accurate for your process to calculate the statistical mean value taking account of the standard deviation in the formula
Records of the samples taken and the number of packages in the
TNE (Tolerable Negative Error) weight band must also be taken. The
values of TNE being calculated via the average weight as detailed in
the 2006 Average weight regulations , comprising percentages and specific weight values based on the nominal quantity , or you could buy scales with this feature built in and record the data onto a USB stick.
Business users can obtain further advice from UK Goverent website or your weights and measures trading standards officer for your locality.
The three rules with which
packers must comply:
- The NET contents of the packages should not be less, on average, than the nominal quantity
- The Number of packages which are short of the stated quantity by a defined amount -TNE 1 should be less than a specified quantity in the batch size.
- The Number of packages in TNE 2 should NOT be short by more than twice the TNE1 value which is abreach of the Packers guide and corrections to your process is required
The first rule is fairly straightforward as its a measured value (weight) and calculated using the standard deviation of the samples.
The second ensures the number of PACKAGES (T1) are within prescribed limits
The third means the NUMBER of PACKAGES (T2) are outwith the "PACKERS" guide and the BATCH has FAILED, rectification of the batch is required and recorded.
