Kamstrup A/S Industrivej 28 DK-8660 Skanderborg T: +45 89 93 10 00 M: email@example.com CVR: 21248118 Hygiene Concept Kamstrup February 6 th , 2023 1. Objective of our Hygiene Concept Kamstrup has prepared a Hygiene Concept to ensure that our water meters do not include any hazardous bacteria (e.g. Pseudomonas aeruginosa ) and that all materials used in drinking water installations are approved materials. 2. Design and development of Kamstrup products All materials are carefully selected to comply with the requirements of international drinking water directives. Furthermore, our water meters are by design fitted with state-of-the-art ultrasonic technology and do not include any moving parts. In combination with a 24-hour drying period, this construction ensures that no residual water remains inside of the water meter. Our water meters have obtained the following drinking water approvals: • Germany: DVGW W421-certified (KTW for chemical parameters and W270 for microbiological resistance) • Germany: UBA-BWGL • Austria: ÖVGW QSW 601 • Netherlands: KIWA • Great Britain: WRAS • France: ACS • USA: NSF-61 • Switzerland: SVGW • Belgium: Belgaqua • Czech Republic: SCU • Poland: PZH • Romania: DRSPB • Denmark: Approved for drinking water, indicated by “Dråbemærket” • Italy: DM 174/2004 • Hungary: NNK 3. Automated production Our state-of-the-art automated production in Denmark guarantees the highest product quality and the best hygienic conditions, with manual production steps largely avoided and control and monitoring performed only by skilled engineers. All processes have been clearly defined and fully documented according to ISO 9001. 4. Test stands Our hygiene concept has been implemented on all accredited water meter test stands. The concept includes a number of measures to secure the hygiene of our products. The test water of all test stands is monitored electronically. Our hygiene concept comprises electronically controlled addition of hydrogen peroxide as well as regular change of test water. The hygiene of our test equipment is controlled by the following measures: • Electronic monitoring (24/7) of the content of hydrogen peroxide in the test water • Regular microbiological analysis of the test water for Pseudomonas aeruginosa , E. coli and coliform bacteria performed by an independent DIN EN ISO 17025-accredited laboratory • Regular control of selected water meters smaller than DN125 (min. 6 meters per month) with test for Pseudomonas aeruginosa is performed by an independent DIN EN ISO 17025-accredited laboratory The microbiological test reports are available on request. All findings are supervised and analysed by experts. According to our Kamstrup hygiene guidelines, we tolerate none of these bacteria (0 CFU/100 ml).
