Annex No 2
REFERENCE METHOD FOR
SAMPLING (STATISTICAL) CHECKING OF THE ACTUAL CAPACITY OF BOTTLES
The inspection batch shall comprise bottles of the same design and size, nominal capacity, material and manufacture.
The size of the inspection batch shall be determined by the hour’s production.
A random sample shall be drawn from the batch and the actual capacity of each bottle shall be measured.
The actual capacity shall be measured by weighing at 20 C.
The bottles shall be weighed empty, then filled with water at 20 C of a known density, up to the filling level appropriate to the method of checking used. They shall be then weighed in full.
The average of the actual capacities of the bottles measured shall be calculated and then estimated by one of the following statistical methods:
- the standard deviation method;
- the average range method.
The number of bottles constituting the sample shall be 35 or 40, depending on which of the two methods has been chosen.
If the result of the check of a batch corresponding to an hour’s production is not satisfactory, a second test can be carried out, based on another sample from a batch corresponding to a longer period of production or the results recorded on the manufacturer’s check-cards can be checked instead.
Checking the actual capacities of bottles by estimating the average of the actual capacities of the bottles in the sample using the standard deviation method
A random sample of 35 bottles shall be drawn. The actual capacities xi of the bottles in the sample shall be measured.
Calculate as follows:
- the mean value of the actual capacities xi of the bottles in the sample;
- the standard deviation “s”;
- the upper permissible limit Ts of the actual capacity;
- the lower permissible limit Ti of the actual capacity.
The batch shall be declared to comply with the requirements to the actual capacity if it satisfies simultaneously the following three acceptance criteria:
+ k.s Ts (1)
- k.s Ti (2)
s F(Ts - Ti )(3)
where:k = 1,57
F = 0,266
Calculations
- The mean value of the actual capacities xi of the bottles in the sample
Calculate as follows:
-the sum of the actual capacity measurements xi by the formula
-the mean value of the actual capacities of the bottles by the formula
- The standard deviation “s”
The estimated standard deviation is calculated by the formula:
S =
- The upper permissible limit Ts of the actual capacity
It is calculated as the sum of the indicated capacity and of the maximum permissible error corresponding to this capacity.
- The lower permissible limit Ti of the actual capacity
It is calculated as the difference between the indicated capacity and of the maximum permissible error corresponding to this capacity.
Checking the actual capacities of bottles by estimating the average of the actual capacities of the bottles in the sample using the average range method
A random sample of 40 bottles shall be drawn. The actual capacities xi of the bottles in the sample shall be measured.
Calculate as follows:
- the mean value of the actual capacities xi of the bottles in the sample;
- the average range of the actual capacities of the bottles in the sample;
- the upper permissible limit Ts of the actual capacity;
- the lower permissible limit Ti of the actual capacity.
The batch shall be declared to comply with the requirements to the actual capacity if it satisfies simultaneously the following three acceptance criteria:
+k-.≤ (1)
- k-.≥(2)
≤F- ( - )(3)
where
k-= 0,668
F- =0, 628
Calculations
- The mean value of the actual capacities xi of the bottles in the sample
Calculate as follows:
-the sum of the actual capacity measurements xi by the formula
-the mean value of the actual capacities of the bottles by the formula
- The average range of the actual capacities of the bottles in the sample
Divide the sample, in chronological order of selection, into eight sub-samples of five bottles each.
Calculate as follows:
-the range of each of the sub-samples, i.e. the difference between the actual capacity of the largest and the smallest of the five bottles in the sub-sample; eight ranges are thus obtained: R1, R2, R3…R8 ;
-the sum of the ranges of the eight sub-samples: R1+ R2+ R3+…+ R8
The average range is then calculated by the formula:
- The upper permissible limit Ts of the actual capacity
It is calculated as the sum of the indicated capacity and of the maximum permissible error corresponding to this capacity.
- The lower permissible limit Ti of the actual capacity
It is calculated as the difference between the indicated capacity and of the maximum permissible error corresponding to this capacity.
The “k” and “F” coefficients applied by the standard deviation method as well as the k- and F- coefficients applied by the average range method correspond to the ones specified in BDS 11052-82 for statistical acceptance sampling.
