Services for Sensor Manufacturers
The Benefits of Independent Validation & Verification

Water utilities and many industries (e.g. food & beverages industry) have to conform to strict regulations in their processes or end-products with regard to water quality. Consequently, many utilities and industries implement only proven water quality monitoring technologies in order to safeguard public health or ensure compliance with discharge permits. This approach however may hamper the adoption of new and innovative monitoring technologies which could effectively solve (near) future water quality monitoring issues.

As a manufacturer of new, innovative water quality monitoring technology you may have experienced the utilities’ hesitation in adopting new monitoring technologies. Thus, independent validation and verification testing can boost the adoption of new, innovative water quality monitoring technologies while at the same ensuring that the technology the water utilities wish to implement actually meets their requirements.

Benten offers the following services as a Test Body under the umbrella of the European ETV programme.

  • VVA-Scan - eligibility check for verification and validation proposal
  • VVA-Claim - a specific claim regarding your (online) water quality sensor
  • VVA-Test - full certification process for a water quality sensor or monitor

Benten’s role is visualised in the schematic overview below.

VVA-Scan

A full certification process for a water quality sensor or monitor requires a considerable amount of effort and investment. Before starting such a process, we need to make sure that the technology under investigation is ready to be validated and verified, so that the certificate can indeed be issued after completing the entire process.
The Benten®VVA-Scan supports you in various ways during preparations for the certification process by:

  • performing an eligibility check of the technology for verification under the EU ETV programme;
  • identifying the relevant technology group under the EU ETV programme;
  • outlining the steps and requirements of a successful verification procedure;
  • initiating contact with the Verification Body competent for the technology under review;
  • indicating the course of the verification procedure and range of costs involved.

If the eligibility check is positive and you decide to continue with the procedure, we can support you in the compilation of a proposal file for the verification body, including a general description of the technology, the initial performance claim and the intended application of the technology.

VVA-Claim

Instead of performing a complete verification procedure under the EU ETV programme, it is also possible to put forward a specific claim regarding your (online) water quality sensor or monitor.

The Benten®VVA-Claim process is as follows:

  • determination of tests necessary;
  • development of a test plan;
  • performance of agreed tests;
  • preparation of comprehensive test report including: data collected, statement regarding validity of claim, review of test procedure


This process does not result in a formally accepted certificate, but the test report can be used for marketing purposes or to identify improvements in your monitoring technology. This procedure is thus also very suitable for prototype testing.

The costs of a VVA-Claim are thus lower than for a full verification test (VVA-Test).

The Verification Procedure can commence after a positive response to the eligibility check and the submission of the proposal file to the verification body. Benten supports you throughout the entire procedure by taking on all administrative tasks and communication with the verification body regarding the protocol to be established and tests to be performed.

The Benten®VVA-Test process consists of the following steps:

  • an assessment of existing data;
  • selection of a suitable test site;
  • development of a test plan, to be approved by the verification body;
  • execution of the test plan;
  • initial assessment of the data collected and preparation of a test report;
  • initial review of the test procedure.

Next, the verification body assesses the test report and performs the actual verification. When performance data are considered accurate and complete, the verification body undertakes a final review of the procedures followed, and determines whether the performance claim can be verified under the EU ETV programme. A verification report and Statement of Verification is then drafted and published. This Statement of Verification may then be used by you in any dealings with other organisations, for marketing purposes and for official approval.
