Overview

EN 13443-1:2002+A1:2007 is a CEN European standard for mechanical filters used inside buildings on drinking water installations. It covers filters of nominal size DN 15 to DN 100, minimum nominal pressure PN10, particle rating 80 µm to 150 µm, and a minimum design temperature of 30 °C. The standard specifies construction, operation, performance, safety and testing requirements for units permanently connected to the mains at the building point of entry.

Key topics and technical requirements

• Scope and classification
  • Applies only to permanently connected point-of-entry filters (DN 15–DN 100).
  • Filters are designated by nominal size (DN), end connections, filter type (backwashable or single-use cartridge) and nominal pressure (PN).
• Filter types
  • Backwashable filters: cleaned in situ without tools; must allow uninterrupted filtered supply during backwash and provide a backwash outlet compliant with EN 1717.
  • Single‑use cartridge filters: replaceable elements packaged to avoid contamination; replacement tools (if needed) supplied by manufacturer.
• Materials and hygiene
  • Manufacturers must select materials that do not contaminate drinking water; copper alloys must meet dezincification requirements (refer to EN ISO 6509).
• Hydraulic and performance limits
  • Particle rating: maximum rating 100–150 µm; minimum rating 80–120 µm (as verified by test methods).
  • Pressure drop: with a clean element at nominal flow, pressure drop shall not exceed 50 kPa.
  • Filter surface velocity: ≤ 0.15 m3/(h·cm2) for backwashable, ≤ 0.025 m3/(h·cm2) for cartridge filters.
  • Pressure strength and durability: includes bending strength, hydrostatic pressure tests (at multiple of PN), element differential pressure tests (e.g., 80% of PN for 60 min) and dynamic pressure cycling (e.g., 200,000 cycles).
• Testing conditions
  • Tests generally at room temperature with water 10–30 °C (or higher where design temperature exceeds 30 °C).
• Documentation and marking
  • Manufacturer must provide technical documentation, labelling and instructions for installation, operation and maintenance.

Applications and users

• Practical use: point-of-entry particulate removal for residential, commercial and light‑industrial buildings; protects downstream appliances (meters, valves, water heaters) and improves water clarity.
• Primary users:
  • Filter manufacturers and product designers (for compliance and type testing)
  • Building services engineers and installers (specification and selection)
  • Test laboratories and certification bodies
  • Water utilities and regulators assessing product suitability

Related standards

• EN 13443-2: Part 2 (filters with particle rating < 80 µm)
• EN 1717 (protection against backflow)
• EN 1567 (building valves)
• EN 1333 (flanges / PN selection), EN ISO 6509 (dezincification), EN ISO 3822-3 (acoustic tests)

Alternatively, a differential pressure gauge (4) can be used. If the appliance is fitted with a shut off valve, open it fully. Adjust the flow rate by means of the regulating valve (1) installed downstream of the filter. Measure the differential pressure at a range (e.g. 10) of flow rates in order to generate a pressure drop curve (curve A, Figure 5). In order to determine the pressure drop curve for the filter itself, repeat the above procedure with the filter removed (curve B). The filter pressure drop (curve C) is obtained by subtracting curve B from curve A.
