prEN 12259-12

Overview

prEN 12259-12 (CEN) provides guidelines for the approval and type testing of sprinkler pumps used in fixed firefighting systems. The standard covers central centrifugal pumps installed to supply water for fixed sprinkler, water spray and foam systems. It emphasises that sprinkler pumps must be constantly ready for use and able to start reliably in the event of fire or during periodic testing. Where permitted, type approval testing may be carried out at the manufacturer's site.

Key Topics

• Scope and purpose: Defines the intent of testing and approval for sprinkler pumps within fixed firefighting installations.
• Pump types covered: Central centrifugal pumps used for sprinklers, water spray and foam applications.
• Readiness and reliability: Requirements ensuring pumps remain operational and start when required, with an emphasis on dependable behaviour for emergency activation and routine testing.
• Type approval testing: Methods and acceptance criteria for approving pumps; the standard allows tests to be conducted at manufacturers' facilities when appropriate.
• Test methods: Prescriptive approaches to verifying pump performance, durability and operational readiness without specifying site-specific installation details.

Applications

This standard is applicable to stakeholders involved in design, manufacture, testing and approval of pumps for fire protection systems:

• Pump manufacturers seeking type approval and conformity assessment for sprinkler pumps.
• Fire protection engineers specifying pumps for fixed sprinkler, water spray or foam installations.
• Testing and certification bodies conducting on-site or factory type testing.
• Facility owners and installers who require assurance that pumps meet recognised readiness and reliability criteria.

Practical benefits include:

• Clear criteria for pump approval that support consistent product selection and procurement.
• Guidance enabling manufacturers to perform legitimate type testing at their site, reducing logistical constraints.
• Enhanced system reliability and confidence that pumps will operate during a fire event or during periodic testing.

Related Standards

• Other parts of EN 12259 series covering components for sprinkler and water spray systems (refer to the relevant parts for valves, alarms and accessories).
• CEN and national standards on fire-fighting systems and components that address system design, installation and maintenance.

For implementers, prEN 12259-12 serves as a practical reference to ensure pump readiness, repeatable test methods and manufacturer-level approval, supporting safer and more reliable fixed firefighting installations.
