NorGeoSpec

A Nordic system for specification and control of geotextiles in roads and other trafficked areas

 

NorGeoSpec is the result of a Nordisk Industrifond project with financial support from the road authorities in Finland, Sweden and Norway and a group of geotextile producers and distributors. The project work is done by VTT and SINTEF and with an advisory group consisting of:

Øystein Myhre and Arne Sørlie, The Norwegian Public Roads Administration, Norway

Pentti Salo, The Finnish Road Administration, Finland

Lovisa Moritz and Ingrid Sødergren, The Swedish National Road Administration, Sweden

Oddur Sigurdsson, VSO Consulting, Island

 

The project has resulted in a common Nordic system for specification and control of geotextiles which is likely to have a strong beneficial effect both economically and technically. We would like to thank the participants in the project and especially the road authorities for the good contribution to the project.

We would also like to give our appreciation to Nordisk Industrifond for the financial support.

The first revision of the NorGeoSpec system is issued 2004.06.30.

A NorGeoSpec Technical Committee (NTC) with representatives from road authorities in the Nordic countries, VTT and SINTEF Civil and Environmental Engineering is established.

 

SINTEF is mandated to be the NorGeoSpec Certification Body (NCB) by the NTC. SINTEF is a Notified Body related to directive 89/106/EEC (ID 1278) for geotextiles and geotextile related products.  

SINTEF issues NorGeoSpec -certificates stating the compliance with the NorGeoSpec requirements.

The compliance with the NorGeoSpec requirements can be verified by two different procedures:

 

- Quality Conformity Attestation (QCA)

- Independent Product Attestation (IPA)

 

QCA: The NCB can issue a QCA certificate according to the following requirements:

 

·        The manufacturer shall provide nominal values and tolerances for the characteristics according to Table 5.1 in the NorGeoSpec-report.

·        The values corresponding to 95% confidence limits (nominal value +/- the tolerances) shall meet the requirements in Table 5.2 in the NorGeoSpec-report.

·        The data provided by the manufacturer must be the same as given on the CE-mark accompanying document.

·        Initial type testing must be performed at all products and for all characteristics. The testing must be performed at an external laboratory, recognised by the NCB. The initial type testing results must fulfil the NorGeoSpec requirements.

·        Evaluation of internal FPC, both system of quality control and the results. The results must comply with the NorGeoSpec requirements.

·        The manufacturer must have a contract with the NCB, which will be responsible for this evaluation and for running continuous surveillance. This involves unannounced sampling at production site and at store and surveillance of internal FPC, both system and results. There will be minimum two random samplings every year.

 

IPA:  The NCB can issue an IPA certificate according to the following requirements:

 

·        The manufacturer shall provide nominal values and tolerances for the characteristics according to Table 5.1 in the NorGeoSpec report.

·        The values corresponding to 95% confidence limits (nominal value +/- the tolerances) shall meet the requirements in Table 5.2 in the NorGeoSpec report.

·        The data provided by the manufacturer must be the same as given on the CE-mark accompanying document.

·        Mean values from accredited tests at an independent laboratory shall be with in the 95% confidence limits. The results from the independent laboratory shall not be older than 3 months at the time of requesting certification.

·        Documentation of the FPC.

 

APPLICATION PROFILE TEST

A test page where applicants can evaluate the application profile of their geotextiles can be found here.

Please note that the application profile test is developed for manufacturers and distributors planning to introduce their products on the Nordic market. This test evaluates only product characteristics. Passing the test is therefore not a guarantee that the product will achieve a specific specification profile or that the product will be certified.

 

Questing regarding certification can be directed to e-mail: post@norgeospec.org
