Il convient que la concentration de substance(s) chimique(s) active(s) et de tout autre ingrédient, même mineur (y compris d’éventuels contaminants), dans l’eau traitée ne dépasse pas les valeurs des paramètres établis par la législation des pays membres relative à l’eau destinée à la consommation humaine, conformément à leur transcription par les autorités nationales.

Overview

EN 15848:2010 - issued by CEN - defines requirements for adjustable chemical dosing systems used as water conditioning equipment inside buildings that are permanently connected to the mains supply. The standard covers definitions, principles of construction (not dimensions), design and performance requirements, safety provisions and specified testing methods for systems that dose chemicals into water intended for human consumption. It also requires that concentrations of active chemicals and incidental components comply with national parametric values for drinking water.

Key Topics and Requirements

• Scope and purpose: Systems must maintain a specified concentration of dosing agent in treated water and be compatible with potable water regulations.
• Dosing system components: Defines required elements such as storage tanks, suction device (hose and foot valve), low-level detection, dosing pump, overpressure valve, injection device and a water meter control signal.
• Materials and contamination control: Parts in contact with drinking water must meet national regulations; tank designs must prevent contamination, degradation and leakage.
• Performance requirements: Manufacturer must specify pump operating characteristics, working flow range, nominal sizes and maximum compatible chemical concentrations.
• Safety features: Includes low-level detection (stops pump when empty), backflow prevention, protection against overdosing (siphonic or gravity flow), accessibility for servicing, and overpressure protection.
• Environmental and electrical safety: Conformance with relevant EN standards for electrical safety and electromagnetic compatibility is required.
• Operating ranges: Minimum requirements include a working temperature of at least 30 °C and specified pressure ranges; testing includes hydrostatic pressure tests (1.5× design pressure or 1 MPa for ≥10–20 minutes).
• Testing & verification: Detailed test rig and procedures for measuring dosing pump stroke volumes (tests at 30%, 60%, 100% stroke; 1 000 pulses) and pressure testing are specified.
• Labeling: Nameplate must show working range, EN 15848 conformity, manufacturer ID, electrical data, maximum working pressure, nominal size and serial number.

Applications and Users

EN 15848 is practical for:

• Manufacturers and designers of adjustable chemical dosing systems and accessories (pumps, injection devices, storage tanks).
• Building services engineers and installers selecting dosing equipment for conditioning drinking water (e.g., corrosion control, disinfection, pH adjustment).
• Water utilities, facilities managers and consultants responsible for compliance with potable water quality and safety.
• Test laboratories and conformity assessors performing performance and safety tests described in the standard.
