Country Information Slovakia

The Slovak Republic covers an area of 49,014 sq. km and has a population of nearly 5,5 million. Bratislava is the capital city, a political, commercial and cultural centre with a population of about 450,000 citizens. The political system of the Slovak Republic is parliamentary democracy. The legislative power rests with Parliament having 150 delegates elected for 4-year period, but some regulations are issued as Regulations of the Government of the Slovak Republic and Ministerial decrees. The head of a state is a president elected directly every five years.

On 1 February 1995 the European Association Agreement concluded between the European Communities and the Slovak Republic came into force, and in 2000 the Slovak Republic became a member of OECD. The Slovak Republic has become a full member of the EU since 1 May 2004. On 21 December 2007 Slovakia became a member of Schengen Area. Since 1 January 2009 the euro is the official currency in Slovakia.

The early days of Slovak metrology can be traced back to the Austro-Hungarian Monarchy when Slovakia formed the integral part of that empire. The Metric Convention was signed by the Austro-Hungarian Monarchy in 1875 as one of the signatory states.

After the declaration of independence, Czechoslovakia signed the Metric Convention in 1922.

The first act on metrology in Czechoslovakia dates from 1962. The scientific base, the Institute of Metrology, was established in the same year.

The international system of units (SI) was enacted as the only system of units in 1975.

The present „old approach“ metrological legislation came into force on 1 July 2000 and at present consists of the following regulations:

  • Act No 142/2000 Coll on Metrology as amended, 
  • Decree No 206/2000 Coll on legal units of measurement in the wording of Decree No 537/2009 Coll, 
  • Decree No 207/2000 Coll on e-marked pre-packages as amended, 
  • Decree No 210/2000 Coll on measuring instruments and metrological control as amended.

This legislation implements EC old approach Directives in the field of metrology and pre-packages.

In 2013 Decree No 419/2013 Coll on non e-marked pre-packages was issued.

In March 2017 the last amendment of Act No 142/2000 Coll came into force. The main reasons for this change were improvement of some provisions relating to metrological control and new requirements on authorization for verification of legally controlled measuring instruments (especially mandatory accreditation) including obligations and rights of authorized bodies.

The legislative framework for New Approach is represented by the Act No 264/1999 Coll on technical requirements for product and conformity assessment as amended. The particular New Approach Directives were transposed into Slovak legislation in the form of Regulations of the Government of the Slovak Republic.

The Slovak Office of Standards, Metrology and Testing (UNMS SR), the central steering body of state administration in the field of metrology, is primarily responsible for legal metrology. UNMS SR reports to the government.

The main task of UNMS SR in the field of metrology is the elaboration of the conception of state policy, preparation of metrological legislation, granting authorization for verification of legally controlled measuring instruments and for carrying out official measurements and steering and supervising the activities of the following specialized and executive bodies of metrology:

Slovak Institute of Metrology (SMU) in Bratislava is the main research and scientific body of state metrology and has the function of a national metrology institute. SMU is responsible for development and conservation of national measurement standards, which represent the basis for traceability of measuring instruments and measurements in the field regulated by the Act on Metrology and also in the non-regulated field. It is the state administration body in the field of metrology issuing type approval certificates. 

Slovak Legal Metrology, non-profit organisation (SLM) is the main executive body of metrology. According to the Act on Metrology, this non-profit organisation fulfils the role of the „designated organisation“. The main task of the SLM is calibration of measurement standards for industry and verification of legally controlled measuring instruments. It has 5 regional workplaces spread over the territory of the Slovak Republic.

Slovak Metrology Inspectorate (SMI) is responsible for state metrology supervision over the measuring instruments and measurements including pre-packages and market surveillance in the field of non-automatic weighing instruments and measuring instruments placed on the market under MID Directive. It is the state administration body.

Authorised bodies are metrological laboratories which being assessed concerning their competence, have been authorized by UNMS SR to perform verification of legal measuring instruments or to perform official measurements. Many of them are accredited by the Slovak National Accreditation Service (SNAS).

The Slovak Republic is a member of the Metric Convention and OIML. The Slovak Office of Standards, Metrology and Testing represent the Slovak Republic in WELMEC as a full member. The Slovak Institute of Metrology is a full member of EURAMET, e.V. and COOMET.

Measuring instruments are generally subject to type approval and initial verification and mandatory reverification unless otherwise stated.

  • Length measures in use for trade 
  • Taximeters 
  • Dimensional measuring instruments
  • Area measuring instruments for leather

  • Gas chromatographs for determination of calorific value of natural gas
  • Instruments for measurement of ionising radiation and radioactivity 

Instruments in the list above covered by New Approach Directives are not subject to type approval and initial verification according to the Act on Metrology (old approach).

Type approval responsibility rests with the SMU for all instruments. SMU has comprehensive test facilities but may use the services of SLM, accredited testing laboratories or testing centres on the basis of a contract. Fees are time-calculated. Type approval certificates are only published in the Slovak language. In the past sixteen years more than 1300 national type approval certificates have been issued.

Initial verification is carried out by SMU, SLM and authorized bodies. In 2016 there were 67 authorized bodies in Slovakia carrying out also subsequent verification of measuring instruments. 

A mandatory reverification system supplemented by random inspection is operated in Slovakia. Reverification is performed mainly by SLM and authorized bodies.

Inspection is the task of SMI.

Reverification intervals are stated in decree No 210/2000 Coll on measuring instruments and metrological control. Typical reverification intervals are:

  • Weighing instruments in use for trade: 2 years
  • Petrol pumps: 2 years
  • Cold water meters: 6 years
  • Hot water meters: 4 years
  • Gas volume meters: 10 or 15 years
  • Electricity meters: 5 to 16 years
  • Thermal energy meters: 4 years

Training of personnel is provided mainly by SMU in its Training Centre.

Personnel providing services in legal metrology have to be certified by SMU in accordance with the valid metrological legislation.

Sanctions are based upon a system of administrative penalties. SMI may impose a financial penalty of up to 10 000 € on anyone who breaks the provisions of the Act on Metrology by, for example:

  • using a measuring instrument without metrological control for a purpose for which this kind of measuring instrument was included into category of legal measuring instruments, 
  • repairing or carrying out installation of legal measuring instruments without registration laid down by the Act on Metrology, or failing to fulfill conditions for registration, 
  • not ensuring the verification of a legally controlled measuring instrument after its repair.

or a penalty of up to 50 000 € on anyone who, for example:

  • places on the market without metrological control a measuring instrument the type of which was not approved although it is subject to approval, or does not correspond to the approved type or was not verified although it is subject to verification,
  • performs verification or official measurement without authorization,
  • places on the market an e-marked prepackage that does not meet the prescribed requirements.

The range of financial penalties depends on the relevance, type, duration and consequences of the non-legal activity.

The Directive has been transposed into the juridical system as the Regulation of the Government of the Slovak Republic No 126/2016 Coll on the making available on the market of non-automatic weighing instruments repealing the Regulation of the Government of the Slovak Republic No 399/1999 Coll on non-automatic weighing instruments in the wording of Regulation of the Government of the Slovak Republic No 150/2002 Coll.

There are two notified bodies in Slovakia carrying out conformity assessment of non-automatic weighing instruments under this Directive – Slovak Institute of Metrology (NB 1781) and Slovak Legal Metrology (NB 1432).

The Directive has been transposed into the juridical system as the Regulation of the Government of the Slovak Republic No 145/2016 Coll on the making available on the market of measuring instruments repealing the Regulation of the Government of the Slovak Republic No 294/2005 Coll on measuring instruments in the wording of Regulation of the Government of the Slovak Republic No 445/2010 Coll. All categories of instruments covered by this Directive are regulated in Slovakia.

Besides two notified bodies – Slovak Institute of Metrology and Slovak Legal Metrology that carry out conformity assessment of measuring instruments under this Directive there is also a private company Bratislavská metrologická spoločnosť s.r.o. (NB 2394) notified for module F for water meters and thermal energy meters.

The following is for information only:

No formal gravity zones have been established in Slovakia for NAWI.

There are no formal requirements for gravity zone markings.

Manufacturers have the responsibility for bringing new instruments within the MPE at the place of their use.

WELMEC approach (as defined in the "Gravity zones" section of the WELMEC 2 guide) is accepted.
