Sweden has a population of about 9 million and covers a land area of 450,000 sq km. About 85 percent of the population live in the southern part of Sweden around the city areas of Stockholm, Gothenburg and Malmö.

Organisational Structure and Background

Sweden has a long history in legal metrology. The Royal Decree on Measures and Weights in 1665 stipulated that important instruments used for measuring length, volume and weight should be controlled by a public authority and provided with a certificate to that effect.

Since 1993, the system for conformity assessment in Sweden is open. It means that private accredited laboratories and inspection bodies perform checks according to regulations. The aim of the open system is to promote competition and to create a free market based on accreditation. Users of measuring devices can order the verification service from any of the accredited bodies operating on the market.

During the last 20 years The Swedish Government has pursued privatisation and deregulation in several sectors, which has considerably changed the infrastructure and implementation of public service provision. Many tasks related to technical inspection and conformity assessment has been privatised under accreditation. Swedish Board for Accreditation and Conformity Assessment (SWEDAC) is the national accreditation body. SWEDAC is also the national central authority for legal metrology.

Two bodies are currently designated as national measurement laboratories: SP Technical Research Institute of Sweden (SP) and the Swedish Radiation protection Authority. The National Metrology Institutes in Sweden are under surveillance of SWEDAC.

SWEDAC is responsible for regulation and for surveillance in the field of legal metrology. Most measuring instruments used for determination of volume or weight are, when used in connection with sale to private consumers, subject to periodic reverification.

SWEDAC is also regulatory- and supervising body for non-food pre-packages. The supervision of prepackages containing food stuff is carried out by National Food Administration.

Equipment Subject to legal metrological controls

In Sweden, the main reason for having regulations for measuring instruments is to protect the private consumer in trade transactions. There are, however, provisions for other types of meters and measuring equipment used in production or running of infrastructure establishments such as airports etc.

Instruments subject to legal metrological control

  • Non-automatic weighing instruments (NAWI)
  • Automatic weighing instruments (AWI)
  • Meters for other liquids than water
  • Water meters
  • Heat meters
  • Electricity meters
  • Taximeters
  • Exhaust gas analysers
  • Prepackages

The instruments listed below are instruments used in situations where the private consumer is effected by the measuring results. For those instruments legal metrological controls is required and practically all of the instruments are subjected to compulsory periodical checks.

  • Non-automatic weighing instruments (NAWI)
  • Automatic weighing instruments (AWI)
  • Meters for other liquids than water
  • Water meters
  • Heat meters
  • Taximeters
  • Electricity meters (regulation in progress)

Control of instruments in service

Sweden operates a mandatory reverification scheme for virtually all of the measuring instruments used for sale or transactions to consumers. Reverification is performed by inspection bodies, accredited according to ISO/EN 17 020 and the SWEDAC administrative regulations in the specific field.

Market surveillance and Surveillance of instruments in use

Market surveillance is normally included in the enforcement activities according to national regulations. SWEDAC is responsible for the activities, however, not necessary the body to carry them out. Normally, it is organised as a nationwide random checking of instruments in use.

Primarily, the main requirements are checked, sealings and markings etc. The formal check is usually combined with a basic function test. The instrument is also evaluated in terms of CE- and M-marking and EC-verification (notified body number) and eventually the Declaration of Conformity.

Directive 90/384/EC

The Directive is implemented by the SWEDAC regulation STAFS 2007:18 on Non-Automatic Weighing Instruments and, as regards article 13, by STAFS 2007:19 concerning reverfication.

Directive 2004722 (MID)

The directive was implemented by a main administrative regulations STAFS 2006:4 (dated 6 of April 2006) and several instrument specific annexes. For some areas, as Automatic weighing instruments for example, the regulation is limited to a certain use of the instrument. As concerns Length and volume meters as well as Dimensional measuring instruments, there are no mandatory regulations.
