The Laboratory for volume and flow offers calibration of density on solid objects, portable density meters, pycnometers and areometers.

The unit density is realized by a normal in the form of a sphere, whose mass and volume are traceable to the units of mass and length, i.e. kilogram and meter. 

Density measures how tightly packed matter is

Termen massa betecknar en viss mängd materia och densiteten är ett mått på hur tätt packad materien är. Den enhet som används är kg/m³, det vill säga massa per volymenhet. Densiteten behöver vara känd vid många praktiska tillämpningar.

The term mass denotes a certain amount of matter and the density is a measurement of how tightly packed matter is. The unit used is kg / m³, i.e. mass per unit volume. The density needs to be known in many practical applications.

We have accredited methods for density determination of solidobjects and calibration of hydrometers and areometers.

Within the range of density, we offer calibration of the following:

• Density - veights and other solid objects
• Portable density meters
• Pycnometers, hydrometers and areometers

Beroende på behov väljer vi lämplig utrustning och metod för att nå önskad noggrannhetsnivå (±0,03 - 10 kg/m³).

The calibration results are reported in a digital calibration certificate in Swedish or English.

The National Laboratory for electrical quantities offers calibration of current measuring and current generating instruments, for example multimeters, electrometers and calibrators.

RISE's calibration at the National Laboratory for electrical quantities is available to customers who require the best possible accuracy in their calibration or have requirements which involves development of new calibration methods. Our customers are found among industry, research institutes, and calibration companies. The national reference standards at the National Laboratory have the highest level of accuracy in Sweden. The traceability to the realisation of the unit is always ensured.

Calibration at a National Laboratory meets all the typical requirements for traceability and accreditation commonly found in industry and society at large.

RISE offers calibration of direct current in the range 10 fA – 6000 A. For calibration of calibrators in the interval 10 µA - 20 A, the current is determined by measuring the voltage across a resistance standard (current shunt). The calibrator is thereafter used as a stable current generator for calibration of current measuring instruments, for example multimeters. The calibrator can, however, be sensitive to different loads. If instead the current measuring instrument is connected in series with a current shunt, the current in the circuit can be determined by Ohm’s law and the measurement will not be load-dependent.

For calibration of currents smaller than 10 µA other instruments are used. For example a source meter to generate small currents, or an electrometer to measure small currents. Source meters and electrometers are calibrated either with a resistance standard (≥100 pA) or with voltage ramps across a capacitance standard (≤100 pA).

For calibration of currents higher than 100 A other methods are used. Those calibrations are carried out by the National Laboratory for high voltage and high current.

Delivery upon agreement with customer. The results of the calibration are reported in a calibration certificate.

The National Laboratory for electrical quantities offers calibration of voltage standards, voltage dividers, and various forms of voltage measuring and voltage generating instruments such as multimeters and calibrators. We also calibrate ECG calibrators.

RISE's calibration at the National Laboratory for electrical quantities is available to customers who require the best possible accuracy in their calibration or have requirements which involves development of new calibration methods. Our customers are found among industry, research institutes, and calibration companies. The national reference standards at the National Laboratory have the highest level of accuracy in Sweden. The traceability to the realisation of the unit is always ensured.

Calibration at a National Laboratory meets all the typical requirements for traceability and accreditation commonly found in industry and society at large.

The calibration resources for direct voltage are in the range of 1 nV – 1MV. In addition to voltage standards we also calibrate different kind of instruments, for example voltage dividers, voltmeters and calibrators. We also calibrate ECG calibrators. For high voltage, above 1000 V, the most common objects are voltage dividers and probes.

Almost all calibration of voltage standards for voltages up to 10 V are fully automatized and are carried out through comparison with groups of primary and secondary voltage standards. The measurement interval can be varied from a few seconds when short term stability is measured, to several weeks for long term stability. The measurement uncertainty is at best 0.3 μV/V.

For calibrations up to 10 V of voltage standards and certain types of voltage dividers we offer calibration with the best possible measurement uncertainty by calibration directly against a Josephson standard. The measurement uncertainty will then be 3 nV/V at best.

Other types of measurements can also be performed, for example extraction of temperature coefficient.

The measurement uncertainty given for a calibration depends, in addition to the calibration equipment’s performance, also on the calibration object’s performance (stability, temperature coefficient, voltage dependence and so on). In most cases, a preliminary estimate of the measurement uncertainty can be given from experience before the calibration.

For more information about our Josephson reference standards and realisation of the voltage unit, see our expertise page on electrical voltage.

Delivery upon agreement with customer. The results of the calibration are reported in a calibration certificate.

When becoming a client you will also get access to our customer website for calibration, where you may also place orders.

Emissions of various gaseous compounds and particles is inevitable in many workplace processes. RISE offer sampling and chemical analysis of airborne compounds and particles in workplace assessments and in laboratory experiments.

Air quality is affected by airborne gaseous compounds and particles and poor air quality may cause adverse health effects. We offer workplace assessments of chemical hazards through sampling of volatile compounds and dust for evaluation and comparison with occupational exposure limits, (OELs) or DNELs (sv hygieniska gränsvärden).

Measurement of air quality in workplace settings may offer valuable information for a company´s future work with occupational health and safety including choice of safety equipment and solutions for ventilation to minimize exposure.

Among species that we can measure by sampling/analysis or using direct reading instruments; VOC (e.g. organic solvents), PAH, acids, ozone, isocyanates, quartz and other dust, oil mist/cutting fluid, allergens etc. Most analysis are made in-house, which is very valuable.

A written digital report is obtained in English or Swedish.

Delivery of report according to agreement.

For workplace assessments a pre-visit may sometimes be preferred and most valuable.

We work mainly with standardized methods for airborne compounds (ISO, EN, NIOSH, OSHA). RISE Research Institutes of Sweden AB, Chemistry and Applied Mechanics is accredited as a testing laboratory according to ISO/IEC 17025:2017 (Accreditation certificate nr 1002).

EN 61034-2 is a fire test method that generates data that is used to evaluate formed smoke density as cables burn. Test results forms a part of the basis for CE marking according to the CPR Construction Product Regulation.

In the product development context, it is important at an early stage to investigate the extent to which cables contribute to smoke development in the event of fire. Fire testing according to EN 61034-2 generates data used to determine smoke density when cables are burned.

Requirements according to the Building Products Regulation (CPR) mean that cables must be CE marked and fire classified according to the Euroclass in order to be sold as building products. In some applications, additional classification of smoke density is required. Data from tests according to EN 61034-2 form the basis for CE marking with supplementary classification s1a or s1b.

The cable to be tested is mounted in 1-meter lengths on a frame placed above a vessel containing a mixture of ethanol, methanol and water. The mixture is ignited and allowed to burn until consumed, about 40 minutes. During the test period, the smoke density formation is measured.

The fire test results are summarized in English in a test report delivered in digital format. 

RISE holds both accreditation and notification regarding this test method why the test report is valid as a part of the CE marking documentation.

Delivery time for accredited test report is usually 4-8 weeks.
Preliminary test results can be shared when the fire test has been carried out, which is usually about 4 weeks after the test material has been delivered to RISE.

Material consumption for testing.depends on the cable diameter, number of cable lengths needed:
40.0 < Ø → 1 pc.
20.0 < Ø ≤ 40.0 → 2 pcs.
10.0 < Ø ≤ 20.0 → 3 pcs.
 5.0 < Ø ≤ 10.0 → N₁ pcs.
where N₁ = 45 / Ø, rounded down to the nearest integer

1.0 < Ø ≤ 5.0 → the cables are distributed in bundles of 7 cable lengths in each bundle. The number of bundles, N₂, depends on the diameter of the cable and is calculated according to:
N₂ = 45/3Ø, rounded down to the nearest integer

Material consumption for non-circular cables differs slightly from the above.

Each cable length is 1 m long.

The air permeability of a fabric is a measure of how well the fabric allows air to pass through it. The air permeability property is of importance for a number of applications, such as for e.g. industrial filters, tents, sails, parachutes, raincoat materials, wind-blocking clothing fabrics, down-proof fabrics and airbags etc.

The method aims to analyse the ability of the fabric to let air pass through the fabric.

In some applications, you do not want air to penetrate the material, e.g. a windbreaker, while in other applications you want the air to pass through the fabric easily. By analysing the air permeability properties of a material, it is possible to assess its suitability for the intended application.

The velocity of an airflow passing perpendicular through a test material under specific conditions of test area and pressure drop is measured, i.e. the velocity required to achieve a desired pressure drop.
The test material is clamped in the air permeability device with the right side facing the air inlet. The air is sucked through the test material, the air flow is adjusted so that the agreed pressure drop is achieved.
The velocity of the airflow is read in mm / s, which is the material's result for the air permeability.

Normal test area is 20 cm² and for garments the pressure difference is normally 100Pa, and for fabrics for industrial use, 200Pa.If the above test area and/or pressure difference is not suitable to use, the alternatives 5 cm², 50 cm², 100 cm² and 50 Pa or 500 Pa may be used if agreed.

If you want to compare the test result, the same test area and pressure drop must be used.

A report in Swedish or English with the received results.

Normal delivery time is 5-10 working days. A more accurate delivery time is stated in the order confirmation which is sent after received order and test material.
