Workflow

 

For obtaining a NordVal International certificate; an approval for the fact that the method performs equivalent (or better) to a reference method requires the following steps:


- Fill in an application form to NordVal International. This gives the steering group of NordVal International information about the applicant and the method.

- Appoint a laboratory (experts, accredited and independent). The laboratory has to be approved by NordVal International. The applicant is making the agreement directly with the laboratory.

- The laboratory forwards a study plan for approval to NordVal International. The study plan and the validations should be performed according to NordVal Protocol (or ISO 16140-2).

- The laboratory carries out the comparison test – an extensive study; testing the selectivity and the reliability of the method.

- The laboratory reports the results.

- The results of the comparison study are reviewed by a Technical Committee (TC) (4 persons) approved by NordVal International and approved by the steering group of NordVal International. The people involved in NordVal International are independent, i.e. they may not have any economical gain in any alternative method development or sale.


- When/If the comparison study is approved, the interlaboratory validation can be carried out. This is organized by the expert laboratory. Only one matrix is required in the interlaboratory study.


- The report of the interlaboratory study is reviewed by the TC and approved by the steering group, if the results are satisfactory.


- When approved, a certificate is issued.

- The certificate is made available on NMKL’s homepage under NordVal International and announced in the NMKL Newsletter. The NordVal International approved methods can be used according to the microbiological criteria (EU 2073/2005).

The secretariat of NordVal International can assist the laboratories in the elaboration of the validation plans, the statistical calculations and so on, if desired and required.
