ISO 16840-10: Rullstolssitsar – Del 10: Resistens mot antändning av
positioneringshjälpmedel – Krav och provningsmetod

Standarden används för att bedöma antändligheten hos kombinationer av material, såsom klädsel och stoppning som används i positioneringshjälpmedel för rullstolar, när de utsätts för en antändningständkälla i form av en värmetrådsspiral.

Denna metod utvärderar endast antändlighetsegenskaperna. För att utvärdera hur en rullstol bidrar till en utvecklad brand måste den provas i full skala med kraftigare antändningskällor.

Provningen äger rum i ett dragskåp med kalibrerat luftflöde. Kombinationer av klädsel och stoppningsmaterial som används i positioneringhjälpmedel provas. Hjälpmedlet provas antingen vertikalt eller horisontellt beroende på hur det sitter monterat på rullstolen. Beroende på storlek på hjälpmedlet så provas antingen slutprodukten eller materialkombinationen i dynan. Oavsett så används en provningsrigg i stål vid försöken. Värmetrådsspiralen appliceras centrerat och i 90 gradig vinkel mot ytan.

Värmetrådsspiralen appliceras i 60 sekunder. För ett godkänt resultat gäller att positioneringshjälpmedlet inte antänder med låga och att det heller inte sker en pyrande antändning som varar längre än 120 sekunder.

Efter provning levereras en provningsrapport på svenska eller engelska med resultaten.

Materialåtgång för en fullständig provning:

• 2 stycken: Färdiga positioneringshjälpmedel alt.
• 2 av vardera Ingående material i dynan med mått 150 mm x 450 mm (vertikal dyna) och 150 mm x 300 mm (horisontell dyna)

We offer equipment and support for testing the pelletization of various types of materials, such as fertilizers, animal feed, and different by-products. The pelletizing machine can either be rented for independent testing of the desired material, or the material can be sent to RISE for evaluation and pellet production.

Pelletization is needed when there is a need to reduce the volume of a material, facilitate transportation, and enable the material to be applied as fertilizer in the field using existing spreading equipment.

We offer the opportunity to:

• Assess the suitability of the technology for the specific material.
• Optimize process parameters.
• Test under real operating conditions.
• Perform chemical analyses of different process stages and, if required, evaluate the material's suitability as a fertilizer.

The equipment is suitable for materials with a dry matter content of approximately 25% (although this may vary depending on the material properties). The equipment can be used to test the pelletization of, for example:

• Various types of fertilizers
• Pet feed
• Biochar blended with other materials

Dewatering of sludge and digestate is essential for reducing volume, facilitating transport, and improving storage opportunities, all of which are important from both environmental and economic perspectives. We offer equipment as well as technical support to test and evaluate the dewatering performance of your sludge or digestate.

Sludge and digestate are produced continuously and therefore require efficient management. These materials can, for example, be used as fertilizers, incinerated, or composted, which means they need to be transported to their final destination. To reduce transportation costs, it is important to decrease the volume of the material, thereby reducing the number of required transports.

When water is removed, phosphorus largely remains in the solid fraction, resulting in a more concentrated nutrient content that is easier and more cost-effective to transport and apply. Nitrogen is predominantly found in the liquid fraction (reject water), which can be utilized locally, for example at anaerobic digestion facilities, or returned to a wastewater treatment plant for further upgrading through processes such as evaporation or ammonia stripping.

The use of sludge and digestate as fertilizers helps recycle valuable nutrients back into the circular economy. After dewatering, the material can be further processed through methods such as drying or pelletizing to create higher-value biofertilizer products. If the sludge is intended for incineration, it must be sufficiently dry, making effective dewatering an essential process step.

Our pilot-scale equipment consists of two separate units: a screw press and a decanter centrifuge.

• The screw press is a simple and robust technology that is particularly well suited for fibrous materials.
• The decanter centrifuge enables a higher degree of dewatering and is better able to handle variations in sludge quality.

The pilot setup with the decanter centrifuge (Lemitec, model MD-80) also includes peristaltic pumps for feeding sludge and polymer into the centrifuge, a mixing tank for the feed sludge, and collection tanks for the dewatered sludge and reject water. The equipment has previously been used to evaluate the dewatering of wastewater sludge and digested food waste.

The main difference between the two technologies lies in their operating principles: the screw press removes water through mechanical compression, whereas the centrifuge separates the solid and liquid phases using centrifugal force. To optimize the separation process, polymer is often added.

Using the pilot-scale equipment, companies can test and evaluate different dewatering technologies on their own sludge or digestate. This makes it possible to:

• Assess the suitability of the technology for a specific material
• Optimize process parameters
• Evaluate polymer performance and selection
• Test under real operating conditions
• Perform chemical analyses of different process streams and, where required, evaluate their suitability for use as fertilizer

Eftersom utrustningen är mobil kan den installeras direkt på anläggningen och köras med verkliga variationer i processen. Utrustningen kan hyras inklusive introduktion på plats samt löpande support från vår personal. Material kan även skickas till RISE där tester kan utföras av RISE personal.

The equipment can be used to test the dewatering of, for example:

• Municipal wastewater sludge from wastewater treatment plants
• Industrial wastewater sludge from industrial treatment plants
• Digestate from biogas plants

A window or door is expected to have several functions and properties. One property is to be able to operate, that is, to open and close a door or window without obstacles or excessive resistance. In normal operation but especially in an emergency situation, this is an important property. Not least in light of accessibility.

RISE offers accredited testing of operating forces for windows and doors according to current European standards.

RISE performs tests in accordance with:

• SS-EN 12046-1:2020 – Windows and doors – Operating forces – Test methods – Part 1: Windows
• SS-EN 12046-2:2025 – Operating forces – Test method – Part 2: Doors

These standards specify how to measure the forces required to operate a product, for example when opening, closing, locking and unlocking.

What does the test involve?

When testing operating forces, how much force is needed to use the product in practice is analysed. For windows, this may include, for example:

• Opening force (starting force and continued movement)
• Closing force
• Operation of fittings, e.g. handles and espagnolette

For doors, the testing includes:

• Force to open and close the door leaf
• Forces to activate the locks and the pushbuttons
• Any forces connected to door closers or automatic functions

The testing takes place under controlled conditions and follows standardized procedures to ensure comparable and reliable results.

Why is testing operating forces important?

Requirements for actuating forces are closely linked to several important characteristics:

• Accessibility – Products should be usable by people with varying physical abilities
• Ergonomics – Reasonable forces reduce strain and increase comfort
• Function and quality – Excessive or varying forces may indicate deficiencies in design or assembly
• Regulatory compliance – Basis for CE marking, product documentation and project-specific requirements

Testing of actuation forces is relevant at several stages:

• In product development and design optimization
• As part of type testing or certification
• For verification against requirements in standards, procurements or projects
• In investigations of functional problems in existing products

The results are reported in a written report that describes how the test item has performed against the applicable classification standard for the essential characteristic.

The report can also be used as a basis for a compiled ITT report and/or as a basis for the manufacturer's declaration of performance for CE marking.

SS-EN 12046-1:2020 – Windows and doors – Operating forces – Test methods – Part 1: Windows

SS-EN 12046-2:2025 – Operating forces – Test method – Part 2: Doors

SS‑EN 1121 is a European testing standard used to evaluate how doors cope with variations in temperature and climate. The test aims to ensure that doors maintain their function, dimensional stability and performance even under demanding climatic conditions.

The standard covers climate testing of door leaves, where the product is exposed to controlled temperature and humidity conditions on both sides. The aim is to simulate real-world conditions, such as temperature differences between the indoor and outdoor environment.

During the test, the following are measured, among other things:

• Deformation (bending/twisting) of the door leaf
• Formal stability over time during repeated climate cycles
• Possible impact on function, e.g. fit in frame

The test is carried out in a climate chamber where the different sides of the door are exposed to specified temperatures according to the different climate classes of the standard. The temperature variations can be significant, which places high demands on the material and construction.

The door's deformation is continuously recorded during and after exposure to the weather. The results are evaluated according to standardized criteria and form the basis for classifying the product's weather resistance.

The results are reported in a written report that describes how the test object has performed against the applicable classification standard EN12210.

The report includes descriptions, relevant accompanying images and drawings.

The report can be used as a basis for a compiled ITT report and/or as a basis for the manufacturer's declaration of performance for CE marking.

We carry out accredited testing or calculation of heat transfer coefficient on windows and exterior doors as well as other building elements

The purpose of the test is to determine the structure's ability to provide thermal insulation.

The thermal transmittance coefficient (U-value) of a structure is determined by testing or calculation.

Testing of windows/doors is carried out according to standard EN ISO 12567-1:2017 or EN ISO 12567-2:2017. Normally tests are carried out for the size 1.23m x 1.48m (window), but other formats can also be used.

For building elements, the standard EN ISO 8990:2000 can also be applied. In this case, the format may be adapted to the testing equipment and nominal dimensions of the material.

Calculation of building structures is carried out according to drawings and descriptions provided by the customer. The procedure is described in the standards EN ISO 10077-1 and 10077-2:2017.

Usually, fixed prices for testing can be stated, but for calculation, access to descriptions and drawings is needed to determine time and cost.

The results are reported in a written report that describes how the test item has performed.
 

The report includes descriptions, relevant accompanying images and drawings.

The report can be used as a basis for a compiled ITT report and/or as a basis for the manufacturer's declaration of performance for CE marking.

We perform accredited testing of acoustic properties on windows and exterior doors. To meet customer demands for quiet and comfortable environments, verified acoustic performance is required. Documented acoustic properties are crucial to demonstrate that windows and exterior doors meet today's sound requirements.

The purpose of the test is to determine the sound insulation capacity of the window or front door.

The accredited test is carried out according to the current standard SS-EN ISO 10140-2 and the results are evaluated according to SS-EN ISO 717-2. The results are reported as weighted sound reduction values, Rw, together with the adaptation terms C and Ctr, which describe the sound insulation of windows and facades in different traffic noise situations.

When the test is complete, the results are reported in a written report that can be used as a basis for a compiled ITT report and/or as a basis for the manufacturer's declaration of performance for CE marking.

The accredited testing is carried out according to the current standard SS-EN ISO 10140-2 and the results are evaluated according to SS-EN ISO 717-2.

We perform accredited rainproof testing of windows and exterior doors.

The purpose of the test is to determine the window or front door's ability to resist rain leakage.

The accredited testing is carried out against the current standard EN 1027

The test is carried out against method A or B. Method B corresponds to an external upper protection of an entrance roof or equivalent. Method A is without this "rain protection" and thus a tougher test for the test object. The test is carried out in different pressure steps with a positive pressure (overpressure) which further stresses the tightness. The amount of water supplied during the test corresponds to 2 liters/m² and minute.

The results are reported in a written report that describes how the test object has performed against the applicable classification standard EN12208.

The report includes descriptions, relevant accompanying images and drawings.

The report can be used as a basis for a compiled ITT report and/or as a basis for the manufacturer's declaration of performance for CE marking.

EN 1027

We perform accredited testing of resistance to wind load on windows and exterior doors.

The purpose of the test is to determine the window or exterior door's ability to withstand wind loads.

The accredited testing is carried out against the current standard EN 12211.

The test consists of three parts, where air tightness is measured before and after wind load (deformation test), deformation test through wind load which is measured on the least favorable parts of the test object and finally a storm safety test is performed.

The results are reported in a written report that describes how the test object has performed against the applicable classification standard EN12210.

The report includes descriptions, relevant accompanying images and drawings.

The report can be used as a basis for a compiled ITT report and/or as a basis for the manufacturer's declaration of performance for CE marking.
