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 additional experiments for sample treatment CEN/TC454 "Algae and algae products"

Background
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. CEN/TC 454, working group 6 ‘Test methods’ is currently developing a CEN standard (working title: “Algae and algae-based products or intermediates – Methods of sampling and analysis – Sample Treament”). The scope of this standard about sample treatment of wet and dry samples is to develop a standard method on drying techniques available, used for seaweed samples. By implementing this method, the analysing laboratories are able to report the most true dry weight percentages, and to obtain samples as most representative as possible for further examination.

Tasks to be performed:

a) Planning the several activities & logistics of the tests to be performed;
b) Performing freeze drying tests and stove drying tests on 4x10 samples (red, brown, green, and micro-algae);
c) Performing stability tests after defrosting the samples;
d) Preparing a report on the test results and on the difference in dry weight content and the stability after storage;
e) Preparing a standard method based on the standards already available.

Open call for additional experiments for chlorophyll CEN/TC 454 "Algae and algae products"

Background
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. In the current market several different quantification methods are applied. This situation may lead to discussions about the right amount of chlorophyll. Therefore a new standard quantification method will be developed. CEN/TC 454, working group 6 ‘Test methods’ is currently developing a CEN standard for this (working title: “Algae and algae-based products or intermediates – Methods of sampling and analysis – quantification of chlorophyll”). The new method will be based on HPLC separation techniques, making as much as possible use of the current standards and methods available. Within the project experiments are foreseen performed by at least two organisations on two different methods, followed by a validation process of the final method selected.

Tasks to be performed:

a) Planning the several activities & logistics of the tests to be performed;
b) Performing chlorophyll measuring tests on x times y samples (red, brown, green, and micro-algae);
c) Preparing a report based on the test results with conclusions considering the advised method;
d) Preparing standard method based on the standards already available;
e) If possible, an attempt will be made to incorporate a more basic method than the HPLC method.
