What is SINTEF Technical Approval
An approval document contains documentation of all relevant properties of the product, as well as information regarding installation instructions, acceptable conditions of use and environmental assessments.
SINTEF monitors internal production control during inspection at the production site. In addition to this, the products are also regularly tested in either our own laboratory, or in other accredited laboratories.
SINTEF Technical Approval is aimed at the Norwegian market, and covers all types of building products, from components to construction systems.
The documentation scheme is suitable for new and established products and applies to both Norwegian-produced and imported construction products.
Basis for approval
SINTEF Technical Approval specifies product properties obtained through type testing and/or calculations, which may be supplemented with experiences gained from practical use.
Products that need to be CE-marked in accordance with the Construction Products Regulation (CPR) must show the CE mark, as well as the corresponding Declaration of Performance (DoP) before a SINTEF Technical Approval for the product can be published.
In addition to the minimum requirement for product documentation, a SINTEF Technical Approval contains documentation of properties, applications and conditions for use recommended by SINTEF, in the Building Research Design Guides, by industry institutions, or in the guidance of TEK.
Content of the Approval DocumentThe approval document contains the following information:
- Product description
- Product performance
- Conditions of use
- Product and factory production control
- Basis for approval
The approval specifies the materials, sub-materials and any component composition used in the product, and possibly references product standards and control descriptions. When approving construction systems, reference may also be made to special construction details which are collected in a separate document and are then a necessary part of the approval.
The approval specifies which applications and conditions the product is approved for, e.g. building parts, building types, climate zones and fire resistance classes.
The approval may include documentation of product performances related to the following basic requirements for construction works:
- Mechanical resistance and stability
- Safety in case of fire
- Hygiene, health and the environment
- Safety and accessibility in use
- Protection against noise
- Energy economy and heat retention
- Sustainable use of natural resources
Product characteristics are, as far as possible, stated in a uniform manner, so that properties and qualities of products of the same type or for the same use can be compared.
Conditions of use
The approval specifies which design requirements must be met before using the product, as well as requirements for installation that are crucial for the product to function as intended.
Product and factory production control
All products with SINTEF Technical Approval shall be subject to continuous surveillance and assessment of product and factory production control. The check shall ensure that the products have the properties stated in the approval at all times. Our experience suggests that such controls have a purpose, as the controls occasionally reveal deviations in production or in the product.
The manufacturer must have a satisfactory system for internal production control, which is monitored through factory visits carried out by either SINTEF, or another technical inspection body. For CE-marked products that require certified production control, then the accreditation, if it can be carried out by SINTEF, will be coordinated with monitoring control for SINTEF Technical Approval.
Basis for approval - technical documentation
The approval document includes a reference list of the most relevant reports from type testing, calculations, etc., which are the basis for the approval.
Environmental related properties
All products with SINTEF Technical Approval have been subject to an environmental assessment. The environmental assessment includes the content of hazardous substances in the product, the release of hazardous substances to the indoor environment, drinking water, soil and groundwater during the use of the product, and routines for waste management and recycling opportunities. The environmental assessment is adapted to the area of use which the product is approved for. SINTEF Technical Approval may also include a reference to environmental declaration (EPD) in accordance with EN 15804.
SINTEF Technical Approval (TG) is approved documentation according to ch.1.1.10 of the Technical Manual for BREEAM-NOR for new buildings 2016 on:
- Issues of air quality (chapter Hea 02 Indoor air quality, ref SN 11 ot table14)
- Absence of pollutants on the A20 list of BREEAM-NOR (ref Mat 01 Sustainable material selection, compliance note SN1 and checklist A20)
Products that can be approved
Labelling of approved products
In order to show that the product has SINTEF Technical Approval, the approval mark and the associated approval number can be used on the product, packaging and in marketing.
Publishing and validity
Holders of SINTEF Technical Approval will multiply the approval documents as needed. Lists of all the products that have been approved at any time, as well as the approval document itself, are published on www.sintefcertification.no. The website is updated continuously.
An approval is issued for five years at a time, but is revised each time changes are made to the product, its use or the conditions of use. The approval document will then get a new date, and the valid version is the one that is published on www.sintefcertification.no.
For each approval, SINTEF prepares a contract with the holder of the approval, and a control description is included as part of the contract. An approval can be withdrawn immediately if the conditions for the approval are not maintained according to either the contract or control description.
Duplicate of SINTEF Technical Approval is an approval that is identical to another approval, but with different product name and/or holder.
Duplicate approval is applicable if;
The holder wishes to marked a product under another product name
The holder wants to have approval for a product under a form of "private-label", in addition to the approval for the product.
Two different companes sell the same product with different product names, and both want to have an approval for the product.
The duplicate must be a pure copy of another approval (the original approval), except for the product name and/or holder
Embossing, marking and recolouring of the product is permitted, provide that this does not affect the properties of the product
The duplicate can only be issued with permission from the holder of the original approval
· Prerequisites for maintaining duplicate approval;
The duplicate is issued with the same validity date as the original approval.
The duplicate is updated when the original approval is updated
The holder of the original approval may at any time withdraw the authorization for duplicate approval
Product and production control for the original approval covers also the duplicate approval
Duplicate approvals have 1/3 annual fee for maintaining the approval
