Overview

SIST EN 15848:2026 establishes comprehensive guidelines for water conditioning equipment inside buildings, focusing on adjustable chemical dosing systems. This European standard defines the requirements for performance, safety, and testing of systems designed to treat water intended for human consumption that are permanently connected to the mains supply. By ensuring controlled addition of chemicals, this standard supports both water quality and user safety, while assisting manufacturers, installers, and operators in achieving regulatory compliance.

Key Topics

Core Definitions and System Components

Adjustable chemical dosing systems allow precise, controllable introduction of water treatment chemicals.

Mandatory components include:

Storage tank with containment for spills,
Suction device (with backflow prevention),
Low-level detection to prevent pump damage,
Dosing pump,
Overpressure valve,
Injection device (with non-return valve and backflow preventer),
Water meter for flow-proportional dosing,
Safety systems for operator/environment protection.

Performance and Safety Requirements

Material safety: All materials in contact with potable water must comply with EU hygiene regulations to prevent contamination.

Electrical and mechanical safety: Systems must meet standards for electrical safety, radio interference, and pressure tolerance.

System integrity: Protection against unintended dosing, leakage, and pressure-related failures is obligatory.

Operating limits: Systems must operate effectively within specified temperature and pressure ranges.

Design and Testing

The standard specifies detailed procedures for testing performance, including:

Flow accuracy tests at various pump settings,
Pressure resistance tests (1.5 times nominal pressure),
Testing for protection against overdosing and backflow.

Labelling: Units must be clearly marked with essential data: working range, compliance information, manufacturer name, electrical specs, and pressure/size ratings.

Applications

Drinking water systems: Ensures safe dosing of chemicals such as disinfectants or conditioners in residential, commercial, and public buildings.

Building water supply management: Supports facility managers and installers in providing consistent water quality.

Compliance and risk management: Helps organizations adhere to EU drinking water quality and safety directives, minimizing risks associated with improper chemical dosing.

Maintenance guidance: Stipulates maintenance, operation, installation, troubleshooting, and repair protocols, promoting system reliability and water hygiene.

Related Standards

For integrated water supply safety and quality, refer to these related standards:

EN 15161: Water conditioning equipment inside buildings - Installation, operation, maintenance, and repair.

EN ISO 12100: Safety of machinery - General principles for design - Risk assessment and risk reduction.

EN 55011: Limits/methods for RF disturbance in industrial, scientific, and medical equipment.

EN 60204-1 & EN IEC 60335-1/2-41: Electrical safety requirements for machinery and appliances.

Directive (EU) 2020/2184: Water intended for human consumption (potable water directive).

Practical Value

Implementing SIST EN 15848:2026 ensures that adjustable dosing systems for building water treatment operate safely, effectively, and in compliance with European legislation. The standard provides a framework for proper selection, installation, use, and maintenance of chemical dosing technology, ensuring consistent water quality and safeguarding public health within buildings. By following these requirements, manufacturers, installers, and facility managers contribute to reliable and sustainable water supply systems.
