The National Laboratory for Temperature offers fixed point calibration of resistance thermometers and thermocouples.

The national laboratories have are responsible for maintaining the national reference standards for each measurement quantity and spreading metrological competence 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.

At present, RISE can realize the following eleven fixed points

• The triple points for water, argon and mercury
• The freezing points for indium, tin, zinc, aluminum, silver, gold and copper
• The melting point for gallium.

This means that RISE has the opportunity to directly reproduce the temperature scale according to ITS-90 in the entire range -189.3442 ° C to 2600 ° C.

Cell type fixing points

All fixing points are of cell type, ie a metal crucible, where the thermometer is inserted into a protective tube surrounded by the pure metal.

The thread method provides calibration up to 1600 ° C

We calibrate platinum-based thermocouples in both fixed-point cells and according to the so-called wire method. In the wire method, gold and palladium wires are melted in a tube furnace so that certain plateaus in the thermo-voltage curve are created, which allows calibration up to 1600 ° C.

We can offer complete fixed point calibrated platinum thermocouples with storage box and calibration table.

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.

Fires can be caused by, for example, bed linens that catch fire through bed smoking. The flammability of bedding products is an important feature to consider when evaluating fire risks. The test is carried out where either a glowing cigarette or a match-like flame equivalent is used as a source of ignition. These two methods are useful for evaluating flammability for pillows, duvets, blankets, sheets, pillowcases, thin bed mattresses etc.

The method aims to evaluate the flammability of bedding products.

The ability of bedding products to be easy ignited provides a basis for assessing its suitability for use in certain environments. Different requirements may apply in different types of environments. In hospital environments, for example, there are more stringent requirements if the product will be used in high-risk environments than if it will be used in normal-risk environments.

The method SS-EN ISO ISO 12952-1 is carried out by placing glowing cigarettes on, under and or between textile layers on the product. The cigarettes will burn out their full length and the sample material is evaluated based on whether or not ignition occurs. The test is performed after the test material has been washed 5 times.

The SS-EN ISO 12952-2 method is performed by placing a match flame equivalent on the product for 15 seconds. The test material is evaluated on the basis of if ignited or not. The test is performed after the test material has been washed 5 times.

One report in Swedish or English containing the test 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 sample material.

Examples of organic substances are additives such as dyes, biocides, surfactants, preservatives, consistency sensors, flame retardants (in, for example, plastics and electronics), plasticizers (phthalates) or other additives in plastics and rubber.

The results of the analyzes can be compared against different EU directives (eg. REACH, RoHS and the toy directive, cosmetics regulation) and different chemical lists (SinList, TEDX etc.) to determine whether the material / product contains CMR (carcinogenic, mutagenic, reproductive toxicants) substances, SVHC substances (Substances of Very High Concern) or classified as PBT / vPvB substance (Persistent, bioaccumulative and toxic / very persistent and very bioaccumulative).

Some functional chemicals that have been noted for environmental reasons include PCBs, PAHs, phthalates, perfluorinated substances (PFOA / PFAS), Bisphenol A (BPA) and various volatile and / or odoriferous substances.

Functional chemicals of biological origin can sometimes vary slightly in composition or being sensitive to heating or otherwise affecting the molecular structure. Therefore, quality control and other characterization of biomolecules place high demands on the laboratory.

Organic substances can be detected in various media such as water, tissues, biomull, particles, waste, air or other gas mixtures as well as in different materials and goods. The substances often occur in very low levels.

RISE has several advanced instruments for detecting, characterizing and quantifying organic substances, including:

• UV-VIS-NIR spectrometer with integrating sphere

• Infrared wavelength range (FTIR) spectrometer

• Liquid chromatographs (LC) with various detectors (MS-MS, UV, RI)

• Gas chromatographs (GC) with different detectors (MS, ECD, FID, TCD)

• XRF, surface layer analysis of a material's elemental composition

The work include both accredited and non-accredited testing methods. The scope of accreditation is available upon request – please feel free to contact us for more information.

Delivery according to agreement and continuous dialogue with the customer.

It is important that the textiles on the market are free of harmful and regulated substances. Chemical analysis is a way to gain control over the products' chemical content.

Society and consumers set high demands on companies and their products. The legislation also means that you as an actor must have complete information and control over the chemicals in your product. It is especially important with products for children and goods with skin contact, such as clothes and accessories.

We can help you interpret the legal requirements in REACH and POPs and propose appropriate analysis.

It is important that the textiles on the market are free of harmful and regulated substances. Chemical analysis is a way to gain control over the products' chemical content.

The major source of PAHs is the incomplete combustion of organic material such as coal, oil and wood. Some PAH are carcinogenic, allergenic (sensitizer) and toxic. Several are persistent, bioaccumulative and toxic in the environment. As a consequence  of this, some PAHs are regulated in REACH.

We can help you interpret the legal requirements in REACH and POPs and propose appropriate analysis.

Aprotic solvents such as DMFa, NMP and NEP are commonly used in polyurethane coatings (PU coatings) of textiles, gloves and "faux leather". The substances are also used in the manufacture of elastomers such as elastane, as well as in the manufacture of aramide fibres (kevlar). The concentrations can be kept down in the end product, but often occur more or less in the materials.

We help you interpret chemical legal requirements and restrictions that apply to goods made of textile materials and plastics and that are linked to e.g. REACH and POPs. We suggest what analyses you need to do based on legal requirements, but also other specifications such as eco-labels or procurement requirements
