Water conditioning equipment inside buildings - Active media filters - Requirements for performance, safety and testing
This European Standard specifies requirements relating to the construction, performance and methods of testing for active media filters for drinking water installations inside buildings, with a maximum working pressure of at least 1 000 kPa and a maximum working temperature of less than 30 °C. It only concerns units, which are permanently connected to the mains supply at the point of entry or point of use.
This standard applies only to filter systems comprising a housing and filter media tested together.
It includes capsule type units where both the element and its outer housing are disposable.
NOTE Products intended for use in water supply systems are to comply, when existing, with national regulations and testing arrangements that ensure fitness for contact with drinking water. The Member States relevant regulators and the EC Commission agreed on the principle of a future unique European Acceptance Scheme (EAS) which would provide a common testing and approval arrangement at European level.
If and when the EAS is adopted, European Standards on products will be amended by the addition of an Annex Z/EAS under Mandate M/136 which will contain formal references to the testing, certification and product marking requirements of the EAS. Until the EAS comes into force, the current national regulations remain applicable.
Anlagen zur Behandlung von Trinkwasser innerhalb von Gebäuden - Filter mit aktiven Substanzen - Anforderungen an Ausführung, Sicherheit und Prüfung
Diese Europäische Norm legt Anforderungen an die Konstruktion, Leistung und Prüfverfahren für Filter mit aktiven Substanzen für Trinkwasser-Installationen in Gebäuden mit einem maximalen Arbeitsdruck von mindestens 1 000 kPa und einer maximalen Arbeitstemperatur von höchstens 30 °C fest. Sie gilt nur für Einheiten, die fest mit der Hausinstallation am Eintrittspunkt oder an der Verbrauchsstelle verbunden sind.
Diese Norm gilt nur für Filtersysteme, die ein Gehäuse und eine Filterkartusche aufweisen, die zusammen geprüft werden.
Sie beinhaltet Kapselfilter-Systeme, bei denen die Filterkartusche und das Außengehäuse entsorgt werden können.
ANMERKUNG Produkte für die Verwendung in Wasserversorgungssystemen, soweit vorhanden, erfüllen die nationalen Bestimmungen und Prüfanforderungen, die ihre Eignung für den Kontakt mit Trinkwasser bestätigen. Die für die Mitgliedstaaten zuständigen Behörden und die EU-Kommission haben sich auf die Prinzipien eines zukünftigen einheitlichen Europäischen Zulassungssystems (EAS) geeinigt, welches eine gemeinsame Prüf- und Zulassungsregelung auf europäischer Basis bietet.
Falls und sobald EAS eingeführt ist, werden die Europäischen Produktnormen um einen Anhang Z/EAS unter dem Mandat M/136 ergänzt, in welchem formale Verweise auf die Anforderungen für die Prüfung, die Zertifizierung und die Produktkennzeichnung im Rahmen des EAS gegeben werden. Bis das EAS in Kraft gesetzt ist, bleiben die derzeitigen nationalen Vorschriften anwendbar.
Appareils de traitement d'eau a l'intérieur des bâtiments - Filtres a substance active - Exigences de performance, de sécurité et essais
La présente Norme européenne prescrit les exigences relatives à la construction, aux performances et aux méthodes d’essai des filtres à média actifs destinés aux installations d’eau potable à l’intérieur des bâtiments, avec une pression de service maximale de 1 000 kPa et une température de service maximale de 30 C. Elle concerne uniquement les unités qui sont raccordées en permanence au réseau public, que ce soit au point d’entrée ou au point d’utilisation.
La présente norme ne s’applique qu’aux systèmes de filtres comportant un logement et un média filtrant qui sont soumis à l’essai ensemble.
Il s’agit notamment de filtres monocorps, où l’élément et son logement sont tous deux jetables.
NOTE Les produits destinés à l’usage dans les systèmes d’alimentation en eau doivent être conformes aux réglementations nationales et aux dispositions d'essais existant éventuellement pour assurer qu’ils sont aptes au contact avec l'eau potable. Les réglementeurs respectifs des États membres et la Commission CE ont convenu du principe d'un futur système européen d’homologation (European Acceptance Scheme = EAS) unique, qui fournirait à l’échelon européen un cadre commun d’essai et d’agrément.
Quand l'EAS sera adopté, s’il l’est, les normes européennes de produits seront amendées par l’ajout d'une Annexe ZA/EAS selon le Mandat M/136, qui contiendra des références formelles aux exigences de l’EAS en matière d’essais, de certification et de marquage du produit de l'EAS. En attendant l’entrée en vigueur de l’AES, les réglementations nationales actuelles demeurent en vigueur.

NOTE The protocols specified in 6.6 of this standard can be adapted to test the reduction of substances not specifically covered by the performance requirements of this standard (see Annex C). Claims for the reduction of such substances are clearly separated from the claims made of conformity to this standard (see also 7.1). 6 Test methods 6.1 Static pressure test of filter housing 6.1.1 Principle The filter is mounted in a test rig and a water pressure 1.5 times the maximum working pressure is applied for 10 min. The filter is examined for visible evidence of leakage or damage. 6.1.2 Procedure Install the filter in a test rig as shown in Figure 1. The pressure gauge shall be installed at the outlet of the test specimen. It shall be ensured that the pressure at the outlet of the system is at the specified value. Flush with water to purge air from the filter. Increase the water pressure to 1.5 times the maximum working pressure at a minimum rate of 0,1MPa/s. Maintain the pressure for 1020+ min. Examine the filter for visible evidence of leakage or damage.

6.2.1 Principle The empty filter housing is mounted in a test rig and subjected to 200 000 load cycles with pressure varying from 150 kPa to 1,3 times the maximum working pressure at a frequency of 15 min-1. The filter housing is examined for visible evidence of leakage or damage. 6.2.2 Procedure Position the filter in a suitable test rig (see Figure 1). Apply 200 000 load cycles with the water pressure cycling between 150 kPa and 1,3 times the maximum working pressure, at a frequency of (15 ± 2) min-1
(see Figure 2). The duration of the pressure increase, pressure hold and pressure decrease shall each be (1 ± 0,2) s. The pressure shall be measured at the outlet of the filter. Maintain the water temperature of the system at (20 ± 3)°C. Examine the filter for visible evidence of leakage or damage. The filter used for the test described in 6.2 shall not be used for subsequent testing.

The filter cartridge is examined for physical evidence of damage to the cartridge and seals. 6.3.2 Procedure Position the filter with cartridge installed in a test rig (see Figure 1). Apply 20 000 load cycles with the water pressure cycling between 1,3 times the maximum working pressure and 150 kPa. The time for the pressure increase and the pressure hold at 1,3 times maximum working pressure shall each be (2,5 ± 0,2) s. The time for the pressure decrease from 1,3 times the maximum working pressure to 150 kPa and the hold period at 150 kPa shall together be (5 ± 0,2) s (see Figure 3). Maintain the water temperature of the system at (20 ± 3) °C. After the completion of 20 000 load cycles, remove the cartridge and examine it for visible evidence of leakage or damage. The filter used for the test described in 6.3 shall not be used for subsequent testing.
Key X Time, in s Y Pressure, in kPa/100 Figure 3 — Dynamic pressure test of filter cartridge 6.4 Pressure drop 6.4.1 Principle The filter is mounted in a test rig and the differential pressure across the filter is recorded for a number of flow rates in order to generate a pressure drop curve. The test is repeated with the filter cartridge removed. The differential pressure curve across the filter cartridge is calculated by subtracting the curve with the filter removed from that with the cartridge in place. For filters with capsule cartridges, the test with cartridge removed is not applied. For these filters, the pressure drop is provided for the complete system. 6.4.2 Procedure The test rig is shown in Figure 4. Connect the filter in accordance with the manufacturer’s instructions supplied with the filter. Install the filter between two sensors for pressure measurement connected to adequately sized manometers (error limit 2 kPa). Alternatively, a differential pressure gauge may be used. If the appliance to be tested is fitted with a shut-off valve, open it fully. Adjust the flow rate by means of the regulating valve installed downstream of the filter. Maintain the water temperature of the system at (20 ± 3) °C. Measure the differential pressure at a number (e.g. 10) of flow rates in order to generate a pressure drop curve (curve A in Figure 5).
