Overview

SIST EN 17450-1:2021 is a European standard developed by CEN for fixed firefighting systems, specifically addressing the water mist components related to strainer and filter components. This part 1 of the series focuses on defining the product characteristics and test methods applicable to strainers and filters used in water supply connections and piping within water mist systems. The standard covers components with filtration grades up to 6 mm and establishes criteria that ensure their performance and reliability in fire suppression applications.

Key Topics

• Product Scope
  Applies to strainers and filters for water mist system piping that filter particles larger than 1 mm (strainers) and 1 mm or smaller (filters).

• Product Characteristics

  • Water Flow: Components must maintain functionality under specified flow conditions without deformation or leakage.
  • Filter Surface Area: The filter element’s surface area must be at least 1.5 times the nominal cross-sectional area of the connected pipe.
  • Design Pressure: Manufacturers specify the design pressure, which components must withstand.
  • Pressure Loss: Should not exceed 5% of published values at maximum system pressure and flow rate.
  • Component Strength: Components must resist deterioration, impact, and maintain mechanical integrity under pressure tests.

• Testing Methods
  Detailed testing protocols ensure compliance:

  • Water Flow Test: Simulates 1.5 times maximum flow velocity for 90 minutes at 1.5 times design pressure.
  • Filter Surface Area Verification: Confirms element surface based on technical documentation.
  • Pressure Loss Test: Measures pressure drop across clean filters under controlled flow conditions.
  • Body Strength Test: Applies pressure at three times design pressure for 10 minutes.
  • Impact Test: Cycles pressure 10 times at design pressure to test durability.
  • Filter Element Strength Test: Applies twice design pressure to check element integrity.

• Marking and Documentation
  Components must be clearly marked for flow direction and include identification codes. Documentation should provide design pressure, flow parameters, filtration grade, model numbers, and connection types to ensure traceability and correct installation.

Applications

SIST EN 17450-1:2021 serves critical functions in the design, manufacturing, testing, and certification of components used in water mist firefighting systems. These systems are widely deployed across multiple sectors due to their efficient fire suppression capabilities with minimal water damage:

• Industrial Fire Protection: Protecting factory machinery, warehouses, and production lines where sensitive equipment is present.
• Commercial Buildings: Used in offices, shopping centers, museums, and data centers requiring effective fire control without excessive water use.
• Marine and Offshore Platforms: Ensures reliable firefighting systems under demanding environmental conditions.
• Transportation Infrastructure: Airports, tunnels, and subways benefit from finely tuned water mist systems that use filter and strainer components compliant with this standard.

By adhering to SIST EN 17450-1:2021, manufacturers and installers ensure components function reliably within water mist systems-preventing clogging, maintaining consistent flow, and resisting pressure fluctuations-ultimately enhancing fire safety performance.

Related Standards

• EN 14972-1: Fixed firefighting systems - Water mist systems - Part 1: Design, installation, inspection, and maintenance. EN 17450-1 references this standard for terminology and complementary requirements.
• EN ISO/IEC 17025: General requirements for the competence of testing and calibration laboratories, relevant for test facilities conducting these component assessments.

Summary

SIST EN 17450-1:2021 defines essential requirements and testing protocols for strainers and filters used in water mist firefighting systems. It ensures that components perform under high pressure, sustain operational flow rates, and resist physical stress, thus guaranteeing system reliability and safety. Implementing this standard supports manufacturers and users in delivering compliant, high-quality water mist systems for robust fire protection across diverse industries.
