• Neutral density filters
• Smoke meter filters
• Band-pass filters
• Interference filters
• Standards for absorbance, transmittance, reflectance or wavelength
• Cuvettes
• Optical liquids
• Colour standards
• Mirrors

Objects are calibrated using a spectrophotometer in a range of 200 nm to 2500 nm. 

Index of refraction is calibrated using an Abbe refractometer. 

The calibrations takes place at the laboratory for photometry and radiometry in Borås.

The calibration results are reported in a digital calibration certificate in Swedish or English which states that the calibration was performed at a national laboratory.

The National Laboratory for Photometry and Radiometry offers calibration of glossmeters and gloss reference standards.

The national laboratories are responsible for maintaining the national reference standards for each measurement quantity and  spreading metrological competens and traceability to industry and society at large. The national reference standards are the highest level of traceability in Sweden. 

A calibration performed at a national laboratory fullfils all typical traceability and accreditation requirements that commonly exist in industry and society at large. 

RISE performs calibrations of gloss in accordance with ISO standard 2813 (or ASTMD523). 

Gloss reference standards are calibrated using a glossmeter that has been calibrated against RISE high gloss standard. Calibration of glossmeters are done by direct measurement against RISE high gloss standard. 

Calibration of medium gloss is calibrated in comparison with a high gloss standard as measured with a glossmeter. The transference to medium gloss increases the measurement uncertainty. The measurement uncertainty is ±1 GU for high gloss and ±2 GU for medium gloss. The measurement uncertainty also depends on the device under test. 

The calibrations takes place at the laboratory for photometry and radiometry in Borås.

The calibration results are reported in a digital calibration certificate in Swedish or English which states that the calibration was performed at a national laboratory.

Calibration of squareness standards is performed up to 500 mm. The calibration is performed against a reference standard on a surface plate. Indicating instruments such as universal protractors, protractors, digital protractors and water levels are calibrated using a sine bar and gauge blocks, alternatively with an indexing table.  Accurate inclinometers from 0,001 mm/m are calibrated on a sine bar of diabase with a laser interferometer as reference.

The calibration results are reported in a digital calibration certificate in Swedish or English which states that the calibration was performed at a national laboratory.

The National Laboratory for Length and Dimensional Metrology calibrates several different types of standards for accurate adjustments of measuring machines. Common standards are for example setting rings (internal diameter), reference gauges (external diameter) and pin gauges, as well as tolerance gauges for control of holes, axles or threads. Additionally, we calibrate customized masters for specific purposes.

Most of these objects are calibrated in a single axis measuring machine with two-point measurement. The contact surfaces of the measurement tips are accurately defined with regards to size and form, which is important for the reproducibility.

The calibration results are reported in a digital calibration certificate in Swedish or English which states that the calibration was performed at a national laboratory.

The length gauges can be with or without measuring force and showing the result in mm (µm) or voltage (mV). We also perform calibration of gauges with lower measuring accuracy and/or longer measuring range up to 2 meters for example string/wire linear potentiometers.

The National Laboratory for Length and Dimensional Metrology offers calibration of laser rangefinders.

Laser rangefinders are one-dimensional length measuring instruments with a measuring range ranging from a few centimetres, to several tens of metres. The measurement principle for most laser rangefinders is the time-of-flight method. In short, the time it takes for a pulse of light to return to the rangefinder is used to calculate the distance.

We offer calibration of laser rangefinders with varying resolution and with a range of up to 50 m. If necessary, we can also develop customized solutions to suit your needs.

The National Laboratory for Length and Dimensional Metrology offers calibration of measuring tapes, dipping tapes and PI tapes.

A calibration performed at a national laboratory fulfils all typical traceability and accreditation requirements that commonly exist in industry and society at large. 

We perform calibration of most kinds of measuring tapes on the market. Our routine calibration at 20 °C includes ten measuring points evenly distributed over the tape. Off course we can calibrate other points on customer requests. We can calibrate each dm up to 5 m and after that every half meter. We calibrate each meter on dipping tapes and ullage level gauges as standard.

Measuring tapes can be made of different materials for example steel and nylon and with different tension forces, normally 50 N. The graduation can start 100 mm in (Type A), from the start of the hook (Type B) or from the hook (Type C). It’s very important that measuring tape with tension force have the same force at use as during the calibration, otherwise the corrections won’t be correct. If the measuring tape is used at other temperature or measuring force than marked at the tape, the length measurements should be corrected.

PI tapes are calibrated due to a different method and other measuring points than usual measuring tapes. This will be described in the certificate.

Measuring tapes are made in different tolerance classes, mainly due to SS 641112, SS 641113 and STAFS 2016:9.

The tolerance grade specifies the maximum allowed deviation on the specified type of measuring tape, but doesn’t say anything about the individual tape. The only way to find out the deviation on a specific tape is by calibration. The calibration is performed without any consideration regarding tolerance class.

The calibration results are reported in a digital calibration certificate in Swedish or English which states that the calibration was performed at a national laboratory.

Gauge blocks are the universal standards that makes it possible to transfer the definition of the metre to a solid standard. We offer calibration of gauge blocks from 0,1 mm -1000 mm, made by steel, tungsten carbide or ceramic materials within three different uncertainty levels. Interferometrical calibration of gauge blocks is our most accurate measuring method, and a direct application of the definition of the central length of a gauge block. The gauge block is wrung to the plane surface of an auxiliary plate and the central length is defined as the perpendicular distance between the surface of the platen and the middle point of the gauge block's top surface. To determine this distance we are using several, different wave lengths of light.

Interferometrical measurements (method “A”) are used when the best accuracy is needed. One typical application is gauge blocks used as standards for mechanical calibration of other gauge blocks. Interferometrical calibration requires very high-quality gauge blocks. The gauge blocks should fulfil grade K according to EN ISO 3650 and have burr free measuring faces.

When the accuracy needed is slightly lower, the gauge block can be measured by mechanical comparison. This method is based on comparison between a standard gauge block and a customer gauge block. We offer two accuracy levels, methods B and C. We are able to calibrate the central length and the length at the four corners for all metric standard lengths from 0,1- 500 mm. That makes it possible to determine the variation in length. For gauge blocks above 500 mm to 1000 mm only the central length is measured.

Method B is intended mainly for gauge blocks used in a laboratory, where high accuracy is needed. Mostly gauge blocks that fulfil Grade 0 or 1, according to EN ISO 3650.  

Method C is mostly used for gauge blocks used in an industrial environment, for example to calibrate handheld measuring tools. Mostly gauge blocks that fulfil Grade 1 or 2, according to EN ISO 3650.

The calibration results are reported in a digital calibration certificate in Swedish or English which states that the calibration was performed at a National Laboratory.
