3. Bottles used as measuring containers (hereinafter measuring container bottles shall be) must comply with this provision the requirements laid down in chapter II.
4. Measuring container bottles shall be consistent with the requirements of this regulation, shall be marked with a mark of conformity in accordance with the provisions of paragraph 14.
II. Metrological requirements measuring devices for metrological characteristics of Measuring 5, which are always specified for a temperature of 20ºc, is the following: 5.1 the nominal capacity Vn-estimated volume of liquid in the measuring of iepildām;
5.2. the volume "up to the top edge of the";
5.3. the actual volume-measuring the actual volume of liquid filled, under conditions that theoretically required to achieve nominal capacity.
6. Measuring container bottles shall be filled: 6.1. constant level;
6.2. constant volume unfilled.
7. All of the same sample for measuring the distance between the nominal capacity theoretically appropriate default level and top level and the difference between the nominal volume and the volume "up to the top edge of the" (blank volume) must be sufficiently stable.
8. the maximum permissible errors (positive or negative deviation) the nominal capacity of the measuring container bottles shall not exceed the provisions mentioned in annex 1.
9. The maximum permissible error of measuring volume "to the upper edge of the" is the same as the nominal capacity.
10. Measuring maximum volume production of measuring the error not allowed to systematically.
11. Measuring the actual volume of test by measuring the temperature of 20 ° C, the quantity of water that is actually in the bottle when it filled to the level corresponding to the nominal capacity. The actual volume can also indirectly using method of equivalent accuracy.
III. The manufacturer's identification mark and the marking of the measuring container bottles 12. each manufacturer of measuring container bottles shall submit to Latvian National Metrology Centre written application measuring identification marks for approval.
13. The Latvian National Metrology Centre may require the applicant: 13.1. changing the identification submitted, if it is similar to the previously approved and they can be mixed;
13.2. to include the identification of the additional numbers or letters.
14. The manufacturer shall certify that the measuring container bottles shall comply with the requirements of these regulations by marking them with the mark of conformity (annex 3). Conformity marking must be clearly legible and indelible.
15. To 8.1 must be clearly visible and the following indelible: 15.1 to measuring the bottom, a bottom border or side surfaces – the indication of the nominal volume of the measuring container bottles shall be in litres (l), centilitres (cl) or millilitres (ml). Figures must be at least six millimetres high, if the nominal volume is over measuring 100 cl, four millimetres high, if the nominal volume is measuring 100 cl and the smaller, but more than 20 cl, and three millimetres high, if the nominal volume of the measuring container bottles shall be not more than 20 cl. Indication of the nominal volume of the measuring container bottles shall be followed by the symbol of the unit or in the name of the measure;
15.2. the measuring container bottles shall be bottom or on the bottom rim, in such a way as to avoid confusion with the previous indication, with the same minimum size digits as they, which indicates the nominal capacity, according to the method of indication of performance: 15.2.1 volume "to the upper edge of the" free expression "centilitres cl";
15.2.2. the distance in millimetres from the top level to the nominal capacity corresponding to the level of performance with the designation "mm";
15.3. the manufacturer's identification mark according to paragraph 12 of these rules;
15.4. measuring conformity mark according to the provisions of paragraph 14.
IV. Measuring of the metrological control of Measuring 16. the manufacturer shall take all measures necessary to ensure a systematic monitoring of the actual capacity of the measuring container bottles and guarantee that the requirements set out in chapter II. Measurement of mass or volume control process carried out in accordance with generally accepted methods of measuring using verified or calibrated measurement tools that are appropriate for the procedures for the correct measurement.
17. in measuring, produced in Latvia which marked with conformity marking, the state metrological control of measuring container bottles shall be carried out at the place of production.
18. the actual capacity of the measuring container bottles shall check the Latvian National Metrology Center according to annex 2 of these rules. Test samples shall be taken at the place of production or, if necessary, by the importer.
19. Expenses related to measuring the actual volume of the test shall be borne by the manufacturer of the measuring container bottles.
20. State metrological supervision over state metrological inspection.
V. closing question 21. Regulations shall enter into force by January 1, 2002.
Prime Minister a. Buchanan, Minister of economy, Minister of agriculture in place of a. Slakter the rules enter into force by January 1, 2002.
 
 
1. the annex to Cabinet of 22 May 2001 on the terms of no. 203 maximum permissible errors (positive or negative deviations) the nominal capacity of the measuring container bottles nominal capacity Vn (ml) maximum permissible error of the Vn from 50 to 100 ml-3 200 3 200 from 100 up to 300-6 from 300 to 500 2 500 from-from up to 1000 1000 to 5000 1-10 from the Minister of economy, Minister of agriculture in place (A). the annex 2 Slakter Cabinet of 22 May 2001 on the terms of no. 203 in the statistical control methods i. sampling for measuring procedure 1 of lots that meet the hourly production output, select a sample from one kind of measuring.
2. One sample is 35 measuring.
3. If the party concerned, the test result is not satisfactory, you can take the test again, taking another sample from a batch corresponding to the longer production period.
II. Measuring the actual volume of measuring 4. Weigh the empty measuring.

6. The test is carried out using the verified measurement tools appropriate to the required procedures. Volume measurement error shall not exceed one fifth of the maximum permissible error corresponding to the nominal capacity of the measuring.
III. Evaluation of the results of measuring container bottles in the sample 7 of volume xi of the actual measurement of the mean value x is calculated using the following formula: 8. a lot of bottles in the actual volume of the xi standard deviation s is calculated using the following formula: 9. Calculation: 9.1 the upper tolerance limit of Ts that is on the specified volume (according to rule 15.1 (a)) and that the volume of the corresponding maximum permissible errors;
9.2. the lower tolerance limit for Ie, which is the difference between the indicated capacity (according to this rule 15.1. section) and this capacity the appropriate maximum permissible error.
10. the Party shall be deemed to conform to the requirements of this regulation, if the value of x and s at the same time satisfy the following inequality: Economic Minister, the Minister of Agriculture A. 3.
