Laboratory for Mass

ACTIVITIES

Laboratory for mass performs activities related to:
• Realization, conservation, maintenance and improvement of the national standards in Montenegro;
• Ensuring metrological traceability in the field of mass in Montenegro through the transfer of the mass unit from the national standard to the secondary and working mass standards;
• Development of the measuring methods for the transfer of the mass unit;
• Calibration of weights of accuracy classes E2, F1, F2, M1 and M2;
• Calibration of weights of free nominal masses that are not in accordance with the OIML R 111:2004
• Calibration of non-automatic weighing instruments;
• Participation in inter-laboratory comparisons;
• Laying down the prescribed technical and metrological requirements for determining the measuring instrument type for mass measuring instruments;
• Verification of weights of accuracy classes F1, F2, M1 and M2.


NATIONAL STANDARDS

The national standard is represented by the sets of weights accuracy class E1, mass scale from 1mg to 20kg, i.e. standards of the finest metrological characteristics which serve as a basis for determining the value of all the other standards of measuring unit for mass. Weights of nominal mass from 1 mg to 500 mg are in the form of wire, weights of nominal mass of 1 g and larger and of greater nominal mass are in the form of a cylinder with grip handle. All weights are one piece construction - monobloc construction, made of high quality stainless steel. Characteristics of weights, in the terms of the measurement uncertainty, maximum permissible error, magnetic susceptibility and permeability, are within the limits of E1 accuracy class weights, in accordance with the OIML R 111:2004 recommendation.


CALIBRATION OF STANDARDS AND MASS MEASURING INSTRUMENTS

Accredited Area:
• Calibration of E2, F1, F2, M1 and M2 accuracy class weights in the range from 1 mg to 10 kg;
• Calibration of weights of free nominal masses whose shape and nominal mass are not in accordance with the OIML R 111:2004 recommendation, ranging from 1g to 50kg;
• Calibration of non-automatic weighing instruments up to 2000kg, on-site, in accordance with EURAMET cg-18: Guidelines on the calibration of non-automatic weighing instruments v.4.0 (11/2015).

Unaccredited Area:
• Calibration of E2, F1, F2, M1 and M2 accuracy class weights of 20 kg nominal mass.


ACCREDITATION SCOPE OF THE LABORATORY FOR MASS

ATCG  HAA 1

VERIFICATION OF THE MEASURING INSTRUMENTS
Laboratory for Mass carries out an examination of mass measuring instruments in order to determine compliance with the prescribed metrological requirements with the aim of verification of mass measuring instruments: accuracy class F1, F2, M1 i M2 weights from 1 mg to 20 kg.

 

TYPE APPROVAL OF MEASURING INSTRUMENTS

In order to ascertain compliance with the prescribed technical and metrology demands, to determine type of measuring instrument, Laboratory for Mass conducts examination of type of further measuring instruments in the field of mass measuring in accordance with Decree on legal measuring instruments that are mandatory subjected to verification and/or the type approval of the measuring instrument (Official Gazette of Republic of Montenegro, No. 81/09):
• weights accuracy class F1, F2, M1 and M2;
• Non-automatic weighing instruments of accuracy class (I), (II), (III), and (IV);
• Automatic weighing instruments;
• Electro-mechanical transducer for weighing instruments;
• Electronic indicator for weighing instruments;


TRACEABILITY SCHEME

Laboratory for Mass achieves metrological traceability through calibration of set of weights accuracy class E1, in the laboratories of the European national metrological institutes (NMI) or authorized institutes (Euramet Designated Institutes) that have published CMC at BIMP KCDB, or are accredited by an accreditation body signatory to the EA MLA agreement. Calibration of the set of weights accuracy class E1, is being conducted every second year alternating. Calibration of the lower accuracy class weights is being conducted by the usage of the equipment of the laboratory for mass, where the mass unit is being transferred on to the standards of the lower accuracy class, by the direct comparison method, over which the mass unit is being transferred from the international to the lower levels in hierarchy, towards the lower level laboratories and to the end users in Montenegro.
