Temporary structures
Scaffolds and ladders that are sold and used in Sweden must be type examined and meet the requirements of the Swedish Work Environment Authority's regulations. RISE performs type control for these products in Sweden and now also has the opportunity to issue certificates for products to be sold in Norway in accordance the Produsentforskriften.
Purpose
We perform analyzes and calculations of all types of building structures, structural details and scaffolding. Some examples of scaffolding that we evaluated with FEM analyzes are scaffolding, pallet racks, temporary grandstands and cable ladders. RISE has extensive experience of evaluations, both against Swedish norms and regulations, as AFS 2013: 4 and AFS 2004: 3, as well as foreign standards.
Scaffolding, scaffolding components and ladders need to be type examined or certified in order for them to be marketed and sold in Sweden and Norway. Examples of products that we can type examine/ certify as an accredited body are:
- Facade scaffolding
- Mobile access tower
- Couplers
- Platforms and woden grating
- Ladders and trestles
- Temporary edge protection systems (for Norway only)
- Safety nets (for Norway only)
RISE is accredited to be able to do this both according to the Swedish Work Environment Authority's requirements in Sweden but also according to the corresponding requirements of the Norwegian Labour Inspection Authority .
Finite Element calculations
Computer calculations are a powerful tool, not least when used in combination with testing, which are increasingly used in product and system evaluation. Advanced calculations are mainly performed using the Finite Element Method (FEM). Component tests are often used to generate input data for the calculation model and full-scale tests for validation of the calculation model. Finite element calculations in combination with scaffolding testing have become a specialty for RISE.
Method
Evaluation and testing of temporary structures are carried out at our accredited operations in Borås where we have our laboratory. We have accreditation for methods in scaffoldings, ladders, trestles, temporary edge protection systems and safety nets.
Deliveries
The result of an assignment is usually a calculation or test report in which the product's properties and carrying capacity are reported. If the product is to be type-examined, a type-examination certificate or certificate will be issued in accordance with the Swedish Work Environment Authority's regulations for the Swedish market or the Norwegian Labor Inspection Authority's regulations for the Norwegian market.
