EN 17451:2024/prA1 is a CEN draft amendment for fixed firefighting systems. It updates the European Standard for automatic sprinkler system pump sets by revising the terminology for assembly and for the entity responsible for the pump set. The scope ties it to sprinkler systems conforming to EN 12845:2015+A1:2019, and it can also be used for pump sets in other water based fixed firefighting systems where applicable.
What does EN 17451:2024/prA1 specify?
EN 17451:2024/prA1 specifies design, assembly, installation and commissioning requirements for pump sets used in sprinkler systems conforming to EN 12845:2015+A1:2019. This draft amendment does not restate the full base standard - it changes selected terminology in EN 17451:2024.
The document is organized as a European foreword followed by two modification clauses:
- Clause 1 - modification to term 3.1.1
- Clause 2 - modification to term 3.1.12
What are the key requirements of EN 17451:2024/prA1?
EN 17451:2024/prA1 makes two targeted changes to the base standard. The practical effect is to clarify what counts as assembly and who is responsible for the finished pump set.
Clause 1 - term 3.1.1
Clause 1 replaces the definition of assembly. In the amended text, assembly means design, production through selection and combination of pump set components, and testing of the pump set. In practice, this makes assembly a broader activity than simple mechanical fitting together - it includes choosing components and checking the completed set.
Clause 2 - term 3.1.12
Clause 2 replaces the definition of pump set manufacturer with pump set assembler. The revised term describes the entity responsible for the design, assembly and build of the pump set. For users of the standard, that shifts attention to the organization that creates the complete unit and carries the associated responsibility.
What this means in use
The amendment is mainly about terminology, but the terminology matters in project documents, technical files and handover records. When a pump set is specified, assembled or commissioned under EN 17451, the revised wording helps identify who does what and what activities are part of assembly.
The scope keeps the standard centered on pump sets for sprinkler systems to EN 12845:2015+A1:2019. Where applicable, the same approach can also be used for other water based fixed firefighting systems.
What terms does EN 17451:2024/prA1 define?
- assembly - in the amended wording, assembly includes design, production by selecting and combining pump set components, and testing of the pump set.
- pump set manufacturer - this older term is replaced in the amendment by pump set assembler.
- pump set assembler - the revised term for the entity responsible for the design, assembly and build of the pump set.
- CEN - the European Committee for Standardization, which publishes the document.
- CEN/TC 191 - the CEN technical committee named in the foreword as the body that prepared the amendment, with the title “Fixed firefighting systems”.
- prA1 - the draft amendment identifier used on this document.
Who uses EN 17451:2024/prA1?
EN 17451:2024/prA1 is used by people who design, assemble, install or commission pump sets for sprinkler systems. That includes sprinkler system engineers, pump set assemblers, fire protection contractors, commissioning personnel, quality managers and buyers who need to identify the responsible party in technical documentation.
It is also relevant to organizations working on other water based fixed firefighting systems where the scope allows the standard to be applied.
What changed in EN 17451:2024/prA1 from the previous edition?
EN 17451:2024/prA1 is a draft amendment to EN 17451:2024. The changes stated in the document replace term 3.1.1, assembly, and term 3.1.12, pump set manufacturer, with updated wording.
Which standards are used with EN 17451:2024/prA1?
- EN 17451:2024 - the base European Standard that this amendment modifies.
- EN 12845:2015+A1:2019 - the sprinkler system standard named in the scope as the system standard for the pump sets covered.
What does the EN 17451:2024/prA1 document contain?
The document contains a European foreword and two short modification clauses. Clause 1 replaces the definition of assembly in term 3.1.1, and Clause 2 replaces the definition of pump set manufacturer in term 3.1.12. Its content is focused on terminology, responsibility and the scope of the pump set standard rather than on detailed design calculations or installation procedures.
For readers, that means the document is mainly useful as a terminology update to the base standard, especially where project documents, test records or supplier responsibilities need to match the revised definitions.
