Ministry of Industry and Trade
of 6 September 2000
laying down requirements concerning bottles used as measuring packages for pre-packaged goods
The Ministry of Industry and Trade provides pursuant to Section 27 of Act No. 505 / 1990 Coll., on Metrology, as amended by Act No. 119 / 2000 Coll., ("the Act ') for the implementation of Section 9a of the Act:
(1) This Decree lays down requirements for bottles used as volumetric packaging (hereinafter referred to as "bottles'), which must be fulfilled only if the manufacturer intends to label the bottles at his choice with the symbol" Winthrop '.
(2) Bottles complying with the requirements of this Order may be marked with the symbol "Winthrop," the graphic form of which is set out in Annex 3 to this Order.

BOTTLE REQUIREMENTS
1. Bottles are characterised by the following volumes, which are always specified for a temperature of 20 ° C:
1.1 nominal volume Vn is the volume marked on the bottle; it is the volume of liquid which is assumed to be contained in the bottle when the bottle is filled in accordance with the conditions of use for which it is intended;
1.2. The aligned volume of the bottle is the volume of liquid contained in the bottle when filled to the edge;
1.3 The actual volume of the bottle is the volume of the liquid that is actually contained in the bottle when it is filled precisely under conditions that are theoretically equivalent to the nominal volume.
2. There are two bottling methods:
(1) constant level,
(2) constant volume of empty space.
The distance between the theoretical filling level to the nominal dimension and the filling level to the brim, to the aligned volume, and the difference between the aligned volume and the nominal volume, known as expansion volume or empty space, must be clearly constant for all bottles of the same type, i.e. for all bottles which have been made according to the same design.
3. In order to allow compliance with the above requirements, while respecting the usual uncertainties at filling, for the purpose of measuring the volume of bottles with appropriate accuracy and, in particular, with the accuracy required by the pre-packaging provisions, the tolerances (positive or negative) of the bottle volume, i.e. the maximum permissible differences (positive or negative) at a temperature of 20 ° C and under the control conditions set out in Annex 2, between the actual volume and the nominal volume of Vn according to the following table:
| Jmenovitý objem Vn v mililitrech | Největší přípustné odchylky | |
|---|---|---|
| jako % z Vn | v mililitrech | |
| od 50 do 100 | - | 3 |
| od 100 do 200 | 3 | - |
| od 200 do 300 | - | 6 |
| od 300 do 500 | 2 | - |
| od 500 do 1 000 | - | 10 |
| od 1 000 do 5 000 | 1 | - |
The maximum tolerance for the adjusted volume shall be the same as the maximum tolerance for the corresponding nominal volume.
Systematic use of tolerances is not permitted.
4. In practice, the check on the actual volume of the bottle shall be carried out by determining the amount of water at a temperature of 20 ° C that the bottle actually contains when filled into a level theoretically corresponding to the nominal volume. The check may also be carried out in an indirect manner by a method the accuracy of which is equivalent.
5. Each bottle manufacturer shall submit the symbol by which it can be identified to the Technical Standardisation, Metrology and State Testing Office (hereinafter "the Office ') for approval. If the symbol is approved by the Authority, it must inform the other competent authorities within one month (2). The manufacturer must, under his own responsibility, equip the bottles with a symbol of your own. This symbol shall be at least 3 mm high.
6. The statistical acceptance shall be carried out in accordance with the principles of the statistical acceptance methods used. The efficiency of the take-over shall be comparable to that of the reference method specified in Annex 2.
7. This decree is without prejudice to the powers of supervisory and other public authorities laid down by law.
8. The bottle shall bear the following unremovable, easily legible and visible data:
8.1 On the side, on the lower edge or at the bottom:
8.1.1. Indication of its nominal volume in litres, centilitres or millilitres, numerals of at least:
- 6 mm high if the nominal volume is greater than 100 cl;
- 4 mm high if the nominal volume is equal to 100 cl or less but greater than 20 cl; and
- 3 mm if the nominal volume is not more than 20 cl.
This indication shall be followed by the symbol of the measurement unit used or, where appropriate, by the name of the unit in accordance with the special legislation 4);
8.1.2 a mark identifying the manufacturer prescribed in paragraph 5;
8.1.3. The symbol prescribed in paragraph 5;
8.2 On the bottom or on the lower edge, in such a way that it does not cause disorientation in relation to the above data, by the figures of the same minimum height as the figures giving the corresponding nominal volume, according to the method or methods of filling for which the bottle is intended:
8.2.1. The figure indicating the balanced volume is expressed in centilitres and is not accompanied by the cl symbol,
8.2.2 or an indication indicating the distance in millimetres from the level of the aligned volume to the level of filling corresponding to the nominal volume, followed by the symbol mm.
Additional information may be provided on the bottle provided that it does not cause disorientation in relation to mandatory data.

METHOLOGICAL CONTROL PROCEDURES
This Annex lays down procedures for the statistical acceptance of bottles to verify that the requirements of Section 4 and Part 6 of Annex No 1 are met.
1. METHOD OF SAMPLING
The choice of bottles of the same design and production shall be taken from a batch which essentially corresponds to hourly production.
If the result of a sample check of the dose corresponding to hourly production is not acceptable, a second test may be carried out based either on a different selection from the batch corresponding to production over a longer period or where the production has been subjected to an inspection recognised by the competent authorities (2), on the basis of the results recorded on the manufacturer's control sheets.
The number of bottles of random selection must be 35 or 40; whichever of the two methods detailed in point 3 below was chosen by the competent authority (2) for the processing of the results.
2. MEASUREMENT OF BOTTLE VIAL OF ACCIDENT SELECTION
The bottles must be weighed empty.
The bottles shall be filled with 20 ° C water, the density of which is known, to a level level corresponding to the control method used.
Then the filled bottles shall be weighed gradually and each value of xji recorded shall be recorded.
Control measurements shall be carried out using a specified gauge suitable for carrying out the necessary operations.
The volume measurement deviations shall not exceed one fifth of the maximum tolerance corresponding to the nominal cylinder volume.
3. USE OF SELECTION CHECKS RESULTS
3.1 Application of the sampling standard deviation method
The required selection range is 35 bottles.
3.1.1 Calculate (see 3.1.4):
3.1.1.1 the sample diameter of x-actual volumes xi bottles in the selection;
3.1.1.2. Estimate of standard deviation with actual volumes of x bottles per batch.
3.1.2. The following shall be calculated:
3.1.2.1. Upper limit value Ts: sum of the declared volume (see Annex 1, Part 8) and maximum tolerances corresponding to that volume.
3.1.2.2. Lower limit Ti: the difference between the declared volume (see Annex 1, Part 8) and the maximum tolerance corresponding to that volume.
3.1.3 Receiving criteria:
The dose must be declared to comply with this decree if the numerical values of x and s satisfy at the same time the following three inequalities:
x Hotel+ K.s ≤ TS,
x--k.s ≥ Ti,
s ≤ F (Ts - Ti),
where k = 1,57 and F = 0,266.
3.1.4 Calculation of the sample mean x- and estimate of the standard deviation with doses:
The calculations shall be made according to the formulae:
- the sum of 35 measurements of the actual volume x = vix,
- sample mean 35 measurements x- = idix35,
- the sum of the square roots of 35 measurements of iguxi2,
- the square root of the sum of 35 measurements of iguxi2 and then 135 iguxi2,
- the difference in the sum of SC = IH2-135 IH2,
- estimation of the variance of the actual volume of bottles in v = SC34
- hence estimate the standard deviation of the actual volume of bottles in s = v.
In order to facilitate the calculation of the selection characteristics, it is recommended to use e.g. pocket calculators with statistical sub-programme (and to calculate the selection standard deviation use the button sn-1 or σn-1).
3.2. Application of an average margin method
The required selection range is 40 bottles.
3.2.1 Calculate (see 3.2.4):
3.2.1.1 the sample diameter of x-actual volumes xi bottles in the selection,
3.2.1.2. Average range of R-actual volumes xi bottles in selection.
3.2.2. The following shall be calculated:
3.2.2.1. Upper limit value Ts: the sum of the declared volume (see Annex 1, Part 8) and the maximum tolerances corresponding to that volume.
3.2.2.2. Lower limit Ti: the difference between the declared volume (see Annex 1, Part 8) and the maximum tolerance corresponding to that volume.
3.2.3 Receiving criteria:
The dose must be declared compliant with this decree if the numbers x- and R- satisfy the following three inequalities simultaneously:
x- + k 'R-≤ Ts
x ITEN-k'R-≥ Ti,
where k '= 0,668 and F' = 0,628.
Calculation of the sample mean of the x- and the average range R- for 40 bottles in the selection and for the range of subgroups 8:
The x- value is obtained by the following procedure:
- sum of 40 measurements of actual volume x = vix
- the sample mean of these 40 measurements x- = idix40,
3.2.3.2. The average spread value of R- shall be obtained by the following procedure:
The selection in the chronological order of sampling shall be divided into 8 subsets, each containing 5 bottles.
The next calculation shall take the following steps:
- for each sub-group, a sampling margin shall be established, i.e. the difference between the measured actual maximum and minimum volume of the five bottles in the subgroup; 8 ranges are obtained as follows: R1, R2,..., R8;
- the sum of the ranges of eight subsets is determined
ITER = R1 + R2 +... + R8.
Thus, the average range R-= 18 GER.
