Cabinet of Ministers Regulations No. 668 in Riga august 22, 2006 (pr. No 43) provisions on metrological requirements measuring instruments dimensionāl Issued in accordance with the law "on conformity assessment" 7. the first part of the article and the law "on a uniformity of measurements" 6. the second paragraph of article 1. determine the metrological requirements and the conformity assessment procedures for measuring dimensionāl features before the means of measuring the dimensionāl is placed on the internal market, as well as placed in service. 2. the meaning of these provisions: 2.1 length measuring tool-measuring equipment for Ribbon-type materials (e.g. textiles, bands, cables) measuring length of supply of the product to be measured during movement;
2.2. area measurement tool-measuring equipment designed for irregularly shaped articles (such as the skin area) for measurement;
2.3. the multidimensional measurement tool-measuring equipment for comprehensive product less rectangular parallelepiped edges (length, height, width). 3. The essential requirements the measuring dimensionāl features certain regulatory provisions on metrological requirements measuring instruments. Specific metrological requirements measuring dimensionāl features identified in the annex to these provisions. 4. the means of measuring the Dimensionāl meet the requirements of these rules and regulatory provisions on metrological requirements measuring instruments. 5. the manufacturer chooses a conformity assessment procedures of the following modules, which are set out in the Act, regulations of metrological requirements measuring features: 5.1. mechanical and electromechanical measuring instruments: F1 or E1 or D1 or B + F or B + E, or B + D or H or H1 or g.;
5.2. electronic measuring instruments and measuring instruments fitted with software: B + F or B + D or H1 or g. 6. Dimensionālo measuring features for which type-approval was issued until the date of entry into force of the rules, allowed to put on the market and the dimensionālo of measurement features that made the first 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. 668 of specific metrological requirements i. requirements common to all dimensionāl means of measuring 1. Electromagnetic interference effects on the means of measuring dimensionāl may take it to: 1.1 changes in the measurement result is not greater than the critical change values, or it is not possible to take any measurements; 1.2. temporary measurement variations can not interpret, write down memory or transferred as a result of the measurements; 1.3. the variations in the measurement result is large enough so that they can observe all the measurement results to interested parties. 2. the critical change value is equal to the value of the scale interval. II. means of measurement of length 3. Textile products are subject to a factor of K, this characterizes the product being measured relative deformation and tensile force applied to the unit area and is calculated using the following formula: K = x (GA + 2.2 N/m2)-fabric sample (width-1 meter) relative extension, if the tensile force is 10 N; GA-fabric sample applied gravity to the unit area, expressed in N/m2. 4. dimensions and coefficient K (specified range) and those belonging to the range of measuring instruments shall be determined by the manufacturer. Factor K values specified in table 1 of this annex. table 1 group K range product I 0 K 2 × 10-< < 2 N/m2 Minimum flexibility (II) 2 x 10-2 N/m2 × 10-8 < K < 2 N/m2 Average flexibility III 8 × 10-2 N/m2 × 10-24 < K < 2 N/m2 IV 24 great flexibility x 10-2 N/K m2 very great flexibility < 5. If the object being measured is not moving the measuring tool, the speed range in which you want to move the object, specified by the manufacturer. 6. If the measurement result depends on the thickness of the material, surface characteristics and mode of delivery (e.g. from a roll or from a pile), corresponding limitations are specified by the manufacturer. 7. Measuring feature maximum permissible error (further-CPC) values determined in table 2 of this annex. table 2 accuracy class MPE I 0.125%, but not less than 0.005 Lm II 0.25%, but not less than 0.01 Lm III 0.5%, but not less than 0.02 Lm Lm-minimum measurable length or shorter length specified by the manufacturer for which the measuring tool is designed for 8 different materials the true length is measured with the suitable measuring media (such as tape). To measure it, lay the material on a suitable surface (e.g. table) and spread evenly. Material may not be pulling out. 9. measuring instruments must ensure that the products to be measured can be measured to tight or not in accordance with the intended nostiepum for which the measuring tool is constructed. III. Area measurement tools 10. the manufacturer shall determine the means of measuring mērdiapazon square. 11. The manufacturer shall determine the limits of the measuring tool, subject to the product (movement) of measuring speed, its thickness and the surface conditions. 12. measurement of the MPE is 1,0%, but not less than 1 dm2. 13. Pulling back or stopping the product being measured the movement is not acceptable measurement errors or indicating device readings. 14. measuring interval of 1.0 dm2 is. Is for the interval 0.1 dm2 for testing purposes. IV. the measurement of Multidimensional features 15. The manufacturer shall determine the means of measuring the dimension range. 16. Section values the minimum dimensions for the lower limit of this annex table 3. table 3 in section (d) minimum dimension (lower threshold) d
