The main task of the time and frequency national standards laboratory is to distribute the Swedish standard time. This is conducted within the framework of national and international timekeeping, time synchronization, research and our calibration and development services.

One of the tasks of the national standards laboratory is to develop and disseminate methods of measurement within the area. 

We perform research and development in areas such as time dissemination and time synchronization, with the help of fiber-optic communication systems, GNSS (Global Navigation Satellite Systems) and the Internet.

RISE provides several traceable services for time and frequency synchronization to various accuracy levels, by such means as GNSS, the Internet and the national Speaking Clock service. 

We also offer calibration services and development of user-specific systems in the area. 

The National Laboratory for Photometry and Radiometry is a leading expertise in optical measurements. We perform calibrations, measurements, examinations and research in the optical wavelength range, i.e. ultraviolet, visible and infrared. 

Optical measurements means the techniques used to measure optical radiant power. The measurement of absolute radiant flux is called radiometry and involves the whole optical wavelength range. It uses units such as Watt and Joule. Photometry is the measurement of light with regards to how humans experience it. This is done by scaling the radiometric measurements by the sensitivity of the human eye. Photometry uses the photometric units, lumen, candela och lux. 

Our expertise includes: 

• Light sources
• Instruments for measuring light
• Optical properties of materials and surfaces
• Lighting
• Light environment
• Experience of light

We also contribute to research projects, both to develop the metrological knowledge base and also in projects where optical measurements are a vital part of problem solving. 

At the National Laboratory for power and energy, Sweden's foremost resources for measurement and calibration in electrical power, energy and electricity quality are located. We are constantly developing reference equipment and measurement methods to respond to industry’s and society's need for traceability. We collaborate with other institutes worldwide and regularly participate in international comparison measurements. We provide traceability through:

• Calibration of power meters, wattmeters or measurement converters
• Calibration of electricity meters and normal electricity meters
• Calibration of power quality instruments

We perform measurements of active, reactive and apparent power, single-phase or three-phase, with 3-wire or 4-wire connection, for all power factors. We can also measure and calibrate voltage, current and power for non-sinusoidal signals.

Metrological competence

Do you need help with measurement technology questions related to electrical measurement technology? We help with advice, training and investigation.

The National Laboratory for Length and Dimensional Metrology is responsible for the realization of the SI-unit for length (the metre) and thereby offer traceability to industry and other parties. Our services include calibration of length standards, measurement of parts, training and advice services. We also offer product evaluation, testing, research and analysis within the area.

Our expertise in dimensional metrology contribute to quality assured measurements and technological development for Swedish Industry. Correct measurements contribute directly to cost savings by reduced cassation and “correct from the start”.

Within industry correct measurements are a fundamental requirement to succeed on an international market. Precision manufacturing as an example, requires low tolerances and it is important to keep the measurement equipment calibrated with a low measurement uncertainty. We offer calibrations with high precision of reference standards and measurement equipment.

The increasing automation in industry and the decreasing tolerances in production will pose tough requirements on measurement accuracy in the future. We can offer expert advice within development and validation of methods for length and dimensional metrology.

As standard services we offer calibration of:

• Gauge blocks and step gauges
• Laser interferometers and laser rangefinders
• Ring gauges and go/no-go gauges
• Scales and tape measures
• Angle standards and instruments
• Surface roughness standards
• Linear transducers
• Roundness and form reference standards
• Measuring wheels

We offer calibrations performed on the “correct” level by competent personnel in environmentally controlled labs.

RISE Calibration offer the possibility to register at our customer website which gives you complete control over your measuring devices by providing a complete overview of all registered devices status, together with history and calibration certificates.

The National Laboratory for Volume and Flow has expertise in flow measurement technology, which means measurement of fluid flows and determination of volume in different vessels such as tanks, volume vessels, glass flasks and pipettes. At the National Laboratory, we can handle flows from 26,000 liters per minute down to 5 nanoliters per minute* (equivalent to 1 liter in 500 years, 1 drop in 7 days, 0.00000000025 m³/h). Extremely low flows have, for example, applications in the development and calibration of medical equipment.

Correct measurements and knowledge of possible deviations and appropriate calibration intervals reduce the risk of incorrect measurements and we can help contribute to direct savings for the industry and society.

Technological development is supported by participating in research and development projects related to volume and flow measurement technology. As part of RISE, we can be an independent party that can coordinate cooperation between different companies and actors in projects and tests. 

The National Laboratory for Volume and Flow at RISE has the country's widest and most accurate resources for measurements and calibrations in the area. We are constantly working to develop and bring forth measurement methods to meet the industry's and society's demands for traceability with the measurement uncertainty required by different applications. This is done both within national and international research projects, and often in collaboration with other organizations and stakeholders.

We are also able to assist with metrological expertise either in investigations of different types of demands regarding measurement, questions concerning the quality of measurements or education in equipment, measurement and measurement uncertainty analysis.

At the National Laboratory for Force and Torque, we provide Sweden's most comprehensive and precise resources for measurements and calibrations in force (newton, N) and torque (newton meter, N·m). We continuously work to develop and improve measurement methods, equipment, and standards to maintain traceability and enhance Swedish competitiveness. We comply with the requirements of ISO 17025, ensuring the quality of our measurements. We collaborate with Swedish industry, universities, and colleges, as well as national metrology institutes in other countries.

An important area of research is in dynamic measurements, where the goal is to establish traceability for rapid changes in force and torque.

What do we do?

• Maintain traceability in force and torque.
• Provide quality-assured measurements and calibrations. We can calibrate forces from 0.5 N to 6 000 kN and torques from 0.1 N·m to 5 000 N·m.
• Offer consultation and metrology expertise to industry and society.
• Train laboratory personnel in force and torque metrology, including measurement equipment, methods, principles, and measurement uncertainty.
• Research and development, both nationally and within international collaboration projects.
• Perform international comparison measurements to ensure the highest measurement quality. Our measurement capabilities (CMCs) are published in the Key Comparison Database (KCDB) and are internationally recognized under the CIPM MRA.
• Participate in standardization work.

The National Laboratory for Temperature has the country's widest and most accurate resources for measurements and calibrations within the temperature range. We work continuously to develop and bring out measurement methods in order to meet the industry's need for traceability with the measurement uncertainty that different applications require. This is done both within national and international research projects, often in collaboration with other organizations and stakeholders.

Due to practical difficulties in realizing the thermodynamic temperature scale, a more practically useful scale, the international temperature scale (ITS-90) has been established internationally, which, with a series of specified fixed points, available reference thermometers and calculation methods as accurate as possible that adhere to the thermodynamic scale. All temperature measurements and calibrations are thus normally made against ITS-90.

We have the opportunity to assist with metrology expertise in the temperature range, whether it concerns investigations on different types of measurement needs, issues relating to the quality of measurements or educational needs in measurement and measurement uncertainty analysis.
