DWD implementation – the Nordic approach OLAV BERGE, NORWEGIAN BUILDING AUTHORITY

, 19.05.2015 Brussels - Matrials and products in contact with drinking water

The MaiD project

Material and product innovation through

knowledge based standardization in

drinking water sector (MaiD)

Objective

4

The overall objective is to increase the

innovation in the drinking water sector by

identifying rational, practical and safe

standards and guidelines for placing materials

and products on the Nordic market.

Purpose is therefore to

• Evaluate the current Nordic approval, acceptance

practice and related standards

• Identify possible Nordic requirements regarding water

quality that needs to be addressed

• Evaluate the applicability of the 4MS acceptance

procedure and related standards

• Evaluate the laboratory capacity in the Nordic

countries

• Recommend the key components that should be

included in a Nordic common acceptance scheme in

order to safeguard drinking water, material quality and

the level playing field

WP3 Aim of the project: Water quality WP leader: Wander

Identify possible Nordic requirements regarding water quality in existing test methods and standards to ensure at least the

present level of protection regarding health and safety.

Evaluate the applicability of the 4MS acceptance procedure and related standards to Nordic conditions. Possible

modifications will be suggested based on the differences in water qualities.

Select leaching tests reflecting real service life of products and

the water qualities in the Nordic countries.

WP 3 Activity Plan 1/2

1 Collection of data

Background information on water supply

Materials used in the drinking water network

Basic data on drinking water quality

• Chemical & microbiological quality

National recommendations and requirements

Corrosion prevention

WP 3 Activity Plan 2/2

2 Data analysis and evaluation

• Determination of microbiological quality of water?

3 Requirements for relevant test waters for the Nordic region

4 Input to standardization of regional test methods

Deliverables: Project report

Aim:

Description of laboratory requirements for future approval

testing of DWMP and required development in order to meet

this.

Expected results: Mapping of the current laboratory DMWP approval testing

capacity Evaluation of strenghts and weaknesses Development requirements regarding capabilility and capacity

WP 4 Laboratory tests and capcity Leader: DTI

Aim:

Recommendation for modified and harmonized approval

testing of DWMP in the Nordic region meeting European

regulations

Expected results:

Recommendation for modified test and test criteria’s

Recommendation for regional test standards

Evaluation of innovation potential

Deliverables:

• 2 magazine article's and one journal article

• Final project report(s)

WP5 Recommendation and guiding documents

Leader: SINTEF

• assessment criteria

• test methods

• competent assessment bodies

• competent test laboratories
