Using the equipment The Sweating Indentor, properties related to microclimate can be measured, which is essential for a product’s perceived comfort.

For products with close-to-body use, such as clothes, furniture, and mattresses, their microclimate properties are important for them to be perceived as comfortable. Such properties are called “thermophysiological properties” within the comfort area, and are crucial for a product to be perceived as “moderately warm” and not cause discomfort due to sweating. By performing measurements with the sweating impression body, numerical values can be assigned to these material properties, which can be of great help in comparing different products and in product development.

Products for which this measurement method is suitable include: Beds, mattresses, seat cushions, and wound dressings.

The Sweating Indentor is heated to body temperature and contains water which can be released through a perforated surface in the form of water vapor at a rate that roughly corresponds to the moisture release from a human body at rest. The impression body can thus be considered to simulate a human body (which emits heat and moisture). By pressing the impression body against the test object, with a temperature and humidity sensor placed in the contact zone, the resulting temperature and relative humidity can be determined

A test assignment results in measurement values for the microclimate that was measured, i.e., the temperature and relative humidity that the test body gave rise to. The test result is documented in a technical report.

It is important that dyed textiles maintain their intended colour and do not bleed onto other fabrics and materials through staining. When we sweat, fabrics that come into contact with the skin can be affected, and if the colour does not adhere as it should, it can cause unwanted staining.

One of the most common sources of consumer complaints is when dyed textiles change and vary too much from the purchased product and become unacceptable to the user. A piece of fabric can have good colour fastness in one state but worse in another. It can therefore be important to test a textile’s colour fastness when exposed to sweat. A good example is a light-coloured bra that is discoloured by a coloured shirt that has become moist from sweat. 

Poor colour fastness can be due to pretreatment, choice of dye, dyeing process, aftertreatment, and use.

The fabric is moistened with sweat liquid and placed under pressure at 37°C for 4 hours together with staining-fabric of the chosen fiber type. Colour change and staining are assessed in a light box under standardized light against a gray scale.

Through artificial weathering, you can, during controlled conditions, determine how well a textile material withstands the impact of external factors such as UV light, temperature, humidity, and rain.

Accelerated weathering allows, during controlled conditions, enable an artificial environment where a textile material can be exposed to external stresses, such as UV light, temperature, and humidity. This is done to predict how the material ages over time.

RISE offer testing according to ISO 4892-2 and ISO 105-B10. Common evaluation after accelerated aging includes color fastness, but mechanical evaluation, such as tensile testing, can also be conducted.

With its extensive experience of how vibration affects objects, RISE can help the customer to develop and carry out relevant tests and determine how well a design or object can withstand mechanical stress from the surrounding environment. We offer accredited testing for a large number of standards (IEC, ISO, ASTM, MIL, etc.).

Vibrations and shocks can damage structures. They can cause mechanical failure or cause electrical malfunction. To prevent these problems, we perform vibration testing from some single hertz up to 2000 hertz. Everything from small to large specimens, in heat or cold, under simultaneous functional monitoring or without. In addition, with RISE unique technical width, we can be a discussion partner and tailor test solutions that facilitate the customer and produce relevant results. 

The mechanical tests are usually performed on our vibrators in our labs. In these labs we also have access to other equipment for environmental durability testing eg. climate chambers. By working closely with our internal suppliers, such as fixtures and workshop services, we solve most things inhouse within a short period of time.

Often results are communicated on an ongoing basis during a test. Sometimes the customer participates during the actual testing. After a completed test, the results are usually documented in a technical report. Most of the reports we issue are accredited. The report can for example provide the basis for further CE marking

We also perform tests other than the above listed methods, both with and without accreditation.

Non-automatic weighing instruments placed on the EU market must comply with the requirements of Directive 2014/31/EU and bear the CE marking. RISE is a Notified Body under the Directive and performs the assessments required to verify that your product complies with the applicable regulatory requirements.

With RISE, you receive an independent and recognized basis for the CE marking of non-automatic weighing instruments. We review the product and its documentation, issue the necessary certificates, and guide you through the process so that you can access the European market efficiently and with confidence.

About non-automatic weighing instruments

A non-automatic weighing instrument (NAWI) is a weighing instrument that requires the intervention of an operator during the weighing process.

The Directive covers, among other things, weighing instruments used for:

• trade and commercial transactions based on weight
• the calculation of taxes, customs duties, and fees
• legal and governmental purposes
• patient weighing in healthcare settings
• prescription compounding in pharmacies
• medical and pharmaceutical laboratories
• direct sales to consumers

• Type Examination (Module B)

The manufacturer submits an application together with the technical documentation. RISE reviews the documentation and assesses whether the weighing instrument complies with the requirements of the Directive. Where harmonised standards are applied, these form the basis of the assessment. If the standards are not applied, RISE develops an evaluation plan in cooperation with the manufacturer.

If the weighing instrument meets the requirements, RISE issues an EU Type Examination Certificate. The certificate is normally valid for 10 years.

• Quality System Assessment (Module D)

RISE assesses the manufacturer's quality system to ensure that production consistently complies with the requirements for the approved weighing instrument type. The assessment includes an initial review followed by regular surveillance activities.

Once the quality system has been approved, RISE issues an Assessment Decision. The certificate is valid for three years and is maintained through annual assessments.

• Product Verification (Module F)

RISE verifies that manufactured weighing instruments conform to a valid type examination certificate. Verification may be carried out on each individual instrument or by statistical sampling.

If the product meets the requirements, RISE issues a Certificate of Conformity. This certificate provides the manufacturer with the basis for using RISE's notified body identification number together with the CE marking on the verified products.

It is the manufacturer's responsibility to ensure that the weighing instrument complies with the requirements of the Directive and is correctly CE marked.

The manufacturer is defined as the person or organisation that places the non-automatic weighing instrument on the market under its own name, regardless of whether the instrument was manufactured by that person or organisation or produced on their behalf by another party.

A first contact with Certification at RISE should be made as early as possible when a product is to be certified.
