Cabinet of Ministers Regulations No. 674 in Riga august 22, 2006 (pr. No 43 13) provisions on metrological requirements automatic weighing instruments Issued in accordance with the law "about the measurement unity of" the second subparagraph of article 6 and the law "on conformity assessment" 7. the first paragraph of article 1. determine the metrological requirements and conformity assessment procedures, which is automatic weighing instruments intended for weight determination by force of gravity on that body, before the automatic weight is placed on the internal market, as well as placed in service. 2. the meaning of these provisions: 2.1 automatic weighing instruments-measuring means for determining the mass of a product without operator interaction and executes automatic processes prebuilt application that contains this specific measuring feature automatic actions;
2.2. Automatic Catchweighers-an automatic weighing instrument that determines the individual pre-packed products (such as bulk goods) or a single bulk product mass;
2.3. automatic checkweigher-an automatic weighing instrument that distribute products with different mass into two or more groups, depending on their weight and set the nominal value;
2.4. the weight of the weight in the label print-Automatic Catchweighers. The label prints weight weight print labels indicating the weight;
2.5. weight and price label printing scales-Automatic Catchweighers. Weight and price label printing scales printed labels indicating the weight and price;
2.6. Automatic Gravimetric filling up the weight-an automatic weighing instrument that fills in the pre-defined packages and virtually constant mass of product from a larger quantity of the product;
2.7. discontinued operations totalising scales (totalising hopper scales) – an automatic weighing instrument that determines the mass of a substance in bulk, dividing it into separate doses. The mass of each individual dose in turn is weighed and summarized. Then each individual dose is added to the total quantity;
2.8. continuous totalising scales-automatic weighing instrument that continuously determines the mass of a bulk product on a conveyor belt, without the products, as well as cutting the dose does not stop the conveyor belt;
2.9. the railway wagon scales-automatic weighing instrument with load receptor, which includes Rails railway wagon handling. 3. The essential requirements for automatic weighing instruments defined in the Act, regulations of metrological requirements measuring instruments. Particular requirements for automatic weighing instruments defined in the annex to these provisions. 4. Automatic weighing instrument meets the requirements of these regulations and legislation for the metrological requirements measuring instruments. 5. The manufacturer may choose conformity assessment procedures of the following modules, which are set out in the Act, regulations of metrological requirements measuring features: 5.1. mechanical systems: B + D, or B + E, or B + F or D1 or F1 or G or H1;
5.2. measurement of electromechanical features: B + D, or B + E, or B + F, or G or H1;
5.3. electronic systems or systems containing software: B + D, or B + F, or G or H1. 6. Automatic weight for which type-approval was issued to this provision to the date of entry into force of the market and allowed to put automatic scales, which made first-time verification, allowed to pass until they use the type approval expiration date, but if it is not set, the-by 2016 of 30 October. 7. The entry into force of the provisions by 30 October 2006. Informative reference to European Union Directive provisions included in the law arising from the European Parliament and of the Council of 31 March 2004, Directive 2004/22/EC on measuring instruments. Prime Minister a. Halloween economic Minister a. Štokenberg annex a Cabinet of 22 august 2006 Regulation No. 674 of specific metrological requirements i. General requirements automatic weighing instruments 1. Manufacturer indicates the instruments under certain operating conditions and characteristics laid down in this annex 2., 3., 4. and 5. 2. Mērdiapazon is defined as the maximum and minimum limits. 3. Electrical energy values:-3.1. nominal voltage or voltage limit values using AC power source; 3.2. the nominal and minimum voltage or voltage limit values using the DC power source. 4. Mechanical and climatic-values: 4.1 the minimum temperature range is 30 ° C, if the other chapters of this annex unless otherwise specified; 4.2. mechanical environment class, which is defined in the Act, regulations of metrological requirements measuring instruments are not applicable. The manufacturer shall determine the conditions of use of the mechanical ones measuring environmental features that are applied on a specific motor voltage conditions, such as mounted in vehicles. 5. other-values: 5.1 operation mode; 5.2. characteristics of the products to be weighed. 6. the requested performance and the critical change values for each measurement feature is specific to related sections of this annex. 7. Specify ways to restrict gradients, "load and the speed of impact to the maximum permissible error (further-CPC) under normal operating conditions should not be exceeded. 8. Ensure adequate equipment for bulk material handling it to normal operating conditions, the MPE is not exceeded. 9. Weight design provides the operator control interfaces (interface) clear visibility and effectiveness. 10. the Operator has the opportunity to determine the indicating device (if any) as to the accuracy of the readings. 11. the zero setting is provided opportunities so that the CPC will not be exceeded. 12. any measurement results that are outside the mērdiapazon, is identified, if the printout is possible. 13. Weights are divided into two main categories. Categories are indicated by X or Y, and this designation is granted by the manufacturer. 14. the main categories are further divided into four accuracy classes as determined by the manufacturer,-XI, XII, XIII and XIV and Y (I), (II) Y Y Y (a) and (b). II. Automatic Catchweighers 15. Category X instruments used to control goods in bulk in accordance with the laws on the metrological requirements fasētaj of the goods and their metrological control arrangements. 16. the accuracy classes are supplemented by a factor (x), multiplied by the maximum specified in point 20 permissible standard deviation value. 17. the manufacturer shall determine the factor (x) in accordance with condition (x)
