By commission of the Swedish authority “Myndigheten för delaktighet” (The Swedish Agency for Participation) RISE has developed a certification scheme for digital social alarms in cooperation with Swedish authorities and leading manufacturers. A test method has been developed and a test set-up for performing the tests has been implemented.

Both alarm senders and alarm receivers are part of digital social alarms. The Swedish Association of Local Authorities and Regions (SKL) require interoperability between alarms of different brands. This is ensured by a standardised communication protocol called SCAIP (Social Care Alarm Internet Protocol). SKL also have several additional dependability and security requirements. These requirements have been included in the test method used for the evaluation and certification of both alarm senders and alarm receivers for digital social alarms.

RISE offer independent testing of alarm senders and alarm receivers to ensure that the requirements stated by the Swedish Association of Local Authorities and Regions are fulfilled. The certificates issued by RISE show that the digital social alarms can be used according to these requirements which is an advantage for both manufacturers and municipalities, e.g., in public procurements of digital social alarms. The manufacturers are also offered access to the test set-up for conducting their own testing of social care alarms.

RISE performs tests of digital social alarms in their own laboratory developed specifically for this purpose. The tests specified in the test method are based on the SEK TS 50134-9 Alarm systems - Social alarm systems - Part 9: IP Communications Protocol and the Swedish Standard SS 91100 Digital social alarm - Social care alarm internet protocol (SCAIP). The “SKL Kommentus Inköpscentral” (The Swedish Association of Local Authorities and Regions’ Central Purchasing) specify several additional dependability and security requirements which also have been included in the test method.

The result of the RISE evaluation is reported in a written report, as well as in a certificate if the requirements are fulfilled.

Delivery time depends on whether the equipment is ready at the start of the evaluation, or if the evaluation takes place in parallel with parts of the development work.

The manufacturer shall document the functions and design of the digital social alarm.

ISO 8191-1:1987 - Furniture – Assessment of the ignitability of upholstered furniture – Part 1: Ignition source: smouldering cigarette.

ISO 8191-2:1988 - Furniture – Assessment of the ignitability of upholstered furniture – Part 2: Ignition source: match flame equivalent.

The standard is used to assess the ignitability of material combinations, such as covers and fillings used in upholstered seating, when subjected to a smouldering cigarette and a match flame equivalent as ignition sources.

These test methods only evaluate the ignitability of upholstery combinations. To evaluate the burning behaviour, the end-use furniture needs to be tested in full scale with larger ignition sources.

The tests are performed in a test cabinet with a calibrated air flow. The cover fabric and the filling are put in a test rig to create a small sofa with a 90º angle between seat and back. The ignition sources are applied in the junction between seat and back.

During the cigarette test the test assembly is not allowed to smoulder after one hour from the beginning of the test. The test assembly is also not allowed to show evidence of charring more than 100 mm in any direction apart from upwards from the cigarette.

The test assembly is subjected to a to a match flame equivalent for 20 seconds. No flaming is allowed to continue for more than 120 seconds after removal of the burner tube. The test assembly is also not allowed to show evidence of charring more than 100 mm in any direction apart from upwards from the location of the burner tube.

After testing, a test report in Swedish or English is delivered with the results.

Material needed for testing:

Complete test with 1 ignition source:

• Cover/interliner/wadding, 2 pieces with the dimensions 800 x 650 mm.
• Filling, 2 pieces with the dimensions 450 x 300 x 75 mm.
• Filling, 2 pieces with the dimensions 450 x 150 x 75 mm.

Complete test with both ignition sources:

• Cover/interliner/wadding, 3 pieces with the dimensions 800 x 650 mm.

A uniaxial tensile test which load, unload and reload up to specific intervals of strain levels. This test provides the information of the elasticity modules strain dependence of the material. Results provides valuable information for forming simulations.

Measure the strain dependence of the material elasticity module during load and unload. This is because theoretically the elasticity module (Young's modulus) generally becomes lower with increased strain on the material. Results provide input data for forming simulations.

A load- reload test is conducted in a hydraulic MTS tensile test machine on a specimen cut out along the rolling direction (can off course be in other directions). The strain on the material is measured using ARAMIS which is a optical 3D deformation measurement system that analyze, calculates and documents strains. ARAMIS measures on a sprayed stochastic pattern were the measurement range is 0.01 % up to several 100 %.  

Results delivered according to agreement.

According to agreement.

The testing material rolling direction shall be clearly visible on the sheets.

Standard uniaxial tensile test of sheet metal performed at room temperature or at elevated temperatures up to 1000°C.

Efficient and quality secured method for producing data used in for example forming simulations. The test results can also be used for material- and batch comparisons when investigating solutions on production problems.

The measurements can also be performed on heat-treated materials where we heat-treat the material in an oven to a decided temperature for a chosen time. The tests are called Bake hardening (BH).

Tensile tests are conducted on three samples which are cut out of the sheet in three directions with respect to the rolling direction (0°, 45°, 90°). The tests are done using a hydraulic MTS tensile test machine with maximum load of ± 100 kN at RISE Stamping and forming center located in Olofström Sweden. Strain measurements are conducted using either a videoextenciometer or ARAMIS, which is an optical 3D deformation measurement system that analyze, calculates and documents strains. Both systems measure on a sprayed stochastic pattern where the measurement area range from 0.01 % to several 100 %.

Electrochemical impedance spectroscopy (EIS) is a non-destructive experimental technique used to characterise electrochemical processes such as corrosion. Typical investigation made with EIS are for instance deterioration of protective paints on metals or coatings in batteries, but also precipitation of corrosion products.

The purpose of the technique is to measure and characterize the interface between an exposed surface and the surrounding environment. From the measurement the polarization resistance and double layer capacitance can be obtained. These parameters can then be used to calculate corrosion rates and to describe a corrosion process; initiation of pitting corrosion, the degradation of a protective coating or the precipitation of corrosion products. As opposed to many other electrochemical techniques the measurement is performed in-situ and is non-destructive. This allows for repeated measurements on the same sample to evaluate how the surface changes with time

EIS can be described as measuring the alternating current as a response to an applied alternating potential. By applying the potential over a range of frequencies (usually 100 000 - 0.1 Hz) different electrochemical processes can be separated depending on their time dependence. For example, the charge transfer from a metal atom to an ion, which is a fast process (at high frequencies), and diffusion of ions through a coating, which is a relatively slow process (at low frequencies).  The test is usually performed with the sample immersed in a conductive liquid, an electrolyte. We have the possibility to analyze EIS data using the common electrical equivalent circuit (EEC) approach but also with physics-based/mechanistic models.

ECE Regulation 118, Annex 6 - Test to determine the horizontol burning rate of material.

The method is used to determine the burning rate of horizontally mounted products used internally in vehicles/buses. Also mounted insulation in the engine room and in separate heaters should be tested. Materials can be tested individually or in combination.

Examples of products that can be tested with this method: Any portion of a single or composite material which is within 13 mm of the occupant compartments air space.

In order to use an interior material in buses, the product must meet the fire requirements according to UN ECE Regulation No. 118. RISE is listed by the Swedish Transport Agency, to perform fire testing to be used as a basis for type approval. The type approval is issued by the Swedish Transport Agency.

The test is conducted inside a test chamber where the test specimen is mounted horizontally. The exposed side of the test specimen is subjected to a gas flame from underneath. The burnt distance and the time taken to burn this distance is measureduring the test. The result, the burning rate, is expressed in mm/min.

A test report, in Swedish or English, is deliverd with the test results after testing.

EN ISO 4589-2 Plast - Determination of burning behaviour by oxygen index - Part 2: Ambient-temperature test

When tested according to EN ISO 4589-2, the test results shows the lowest concentration of oxygen, by volume percentage, in a mixture of oxygen and nitrogen introduced at 23°C which supports combustion of a material under specific test conditions. The method is used, among other things, to classify materials for trains and is referred to by EN 45545-2 - Railway applications - Requirements for fire behaviour of materials and Components.

When we take the railway, we assume that the journey will be comfortable and safe. Fire safety is important in order to save lives in the event of an accident. Therefore, all materials and products installed in trains and subways must be fire tested according to EN 45545-2. The system has been developed by Technical Committee CEN/TC 256 ”Railway applications” at the request of the European Commission. The system is based on requirements from EU Directive 2016/797. All contradictory national standards are revoked.

The test specimen is supported vertically in a mixture of oxygen and nitrogen flowing upwards through a transparent chimney. The upper end of the specimen is ignited and the subsequent burning behaviour of the specimen is observed. The period for which burning continues, or the length of the specimen burnt are compared with specified limits for such burning. By testing a series of specimens in different oxygen concentrations, the minimum oxygen concentration is estimated.

A test report, in Swedish or English, is delivered with the test results after testing.

Material needed for testing

Complete test (determination of specific oxygen index)

• At least 20 specimens with dimensions 80 - 150 mm x 10 mm x 4 - 10,5 mm

Reduced test (verification against predetermined oxygen index)

• 8 specimens with dimensions 80 - 150 mm x 10 mm x 4 - 10,5 mm

Depending on the type of material to be tested, the dimensions of the test specimens may differ from the above dimensions
