Openbare aanbestedingen

NEN voert geregeld projecten uit op het gebied van (Europese) normalisatie of advies waarvoor de inzet van externe experts of partner organisaties nodig is. Waar de Europese Commissie (mede)financier is van deze projecten moet voor de selectie van deze experts of partner organisaties veelal een openbare aanbestedingsprocedure worden gevolgd.


Call for Tender

NEN regularly carries out (European) standardisation or advisory projects for which we need external experts or partner organisations. In cases where the European Commission is (co)financing such a project, a public procurement procedure is often required for the selection of the external experts or partner organisations.


Open call for Drafting clause 4 for the Technical Report on specifications for Food and Feed applications (CEN/TC454/WG4) on Novel food legislation

The objective of the project is to develop standardization deliverables in the Technical Committee CEN/TC 454 'Algae and algae products', which was established in the beginning of 2017.

A document needs to be drafted with the following elements (readymade clause 4 for TR and of added value for the overall WG 4):

1. With guidance on “how to get products approved”. What is needed, how long will it take etc. The document will serve as an initial guidance for the standard users and will facilitate future outreach and implementation. The text will be based on experience and desk research. During the creation of this document the experts will act as linking pin between European legislators (e.g. EFSA) and NEN and its contributors.

2. Containing listings of the mismatches of NOVEL Food Regulation and ALGAE products including a first wave assessment of the ways forward to seek compliance and an initial assessment of the risks when commercial (potential) applications are in non-compliance with Novel Food Regulation.

The European Commission (EC) and CEN have signed a contract (SA/CEN/2016-04/ENER/C2/498-2016/SI2.735225) under the Framework Partnership Agreement 2014. The project is titled: "Algae or algae based products or intermediates" and is related to the Standardization Request M/547 as regards algae and algae-based products or intermediates.
CEN/TC454 working group 4 is developing a technical report on algae and algae products specifications for food and feed applications. An alignment with NOVEL Food Regulation will be crucial and inevitably the one of the main outputs in between Algae industry / Novel Food Regulation and required standardisation as assigned to NEN.

More information can be found in the open call.

Applications should be submitted using the attached application form by 22th April. Applications received after the deadline will not be taken into consideration. Applications shall be sent by e-mail to indra.teronde@nen.nl.


Open call for WG 6: Interlaboratory trial & round robin test

The objectives of the two phases are the following:

Phase 1: the interlaboratory trial.
During this trial, the concepts of the standards that should be developed within WG 6 (The Ryckebosch method and the Chlorophyll method) are tested by preferably about 15 laboratories with the aim to test whether the instructions are clear for the user, and whether it will result in the ‘results’ which are expected in advance. This interlaboratory trial is an interactive and informal procedure, where the laboratories could have contact with the main contractor in case of difficulties during the analyses. Within the interlaboratory trial, the laboratories also will be asked to analyse the amount of macro nutrients (like saccharides, proteins and fatty acids) and contaminants being present in the samples; the laboratories are allowed to do this by their own procedures; in doing this the necessity of possible future standardisation issues on micro- and algae can be determined (for instance in a future project under which new algae standards could be developed).

Phase 2: the round robin test.
The round robin test is the formal test of the final procedures for the Ryckebosch method and the Chlorophyll method, both laid down in a CEN standard, currently being developed. In this test, the final versions – which will also will be balloted in the final vote – will be used by the participating laboratories during the round robin test. Since the comments, improvements and suggestions of the interlaboratory trial have been incorporated in the final versions of the method, the chances are minimal that the standards need to be adapted afterwards. In this way, the round robin test must be seen as the final “proof of the pudding” of the final drafts of the two standards.

The work will be split into two phases. First the phase 1: interlaboratory trial. The second phase is called the round robin test.

The trial consists of testing a predefined set of “naturally enhanced” samples and blanks. The participating laboratories shall also be asked to provide information about the sample preparation and extraction methods, and the analysing equipment.

More information can be found in the open call.

Applications should be submitted using the attached application form by the 19th of June 2019. Applications received after the deadline will not be taken into consideration. Applications shall be sent by e-mail to indra.teronde@nen.nl.
