Fixed firefighting systems — Water mist systems

Part 11: Test protocol for cable tunnels for open nozzle system

National foreword

This British Standard is the UK implementation of EN 14972‑11:2023.

The UK participation in its preparation was entrusted to Technical

Committee FSH/18/5, Watermist systems.

A list of organizations represented on this committee can be obtained on

request to its committee manager.

BSI, as a member of CEN, is obliged to publish EN 14972‑11:2023 as a

British Standard. However, attention is drawn to the fact that during

the development of this European Standard, the UK committee advised

against its approval.

It is the view of the UK committee that some of the requirements in EN

14972‑11:2023 are suboptimal to the recommendations in the BS 8489

series and to the protocols that have been in use in the UK to date.

The UK committee also has a concern to the degree of reliance on the

design, installation, operation and maintenance (DIOM) manual to

constrain critical parameters with regard to the whole EN 14972 series

of documents.

The UK committee also has concerns about a number of other aspects

of EN 14972‑11:2023. The UK committee believes that the standard

does not sufficiently cover certain technical and safety matters. These

have been addressed to some extent in the national annexes to BS EN

14972‑11:2023, which are appended at the back of this document.

The limits of application of the fire test protocols and other constraints

have not, at the time of writing, been published. The intended scope and

clear limits of the fire test protocols to the application of this standard

are fundamental to its safe implementation. National Annexes NA and NB

contain the UK committee recommendations (i.e. mechanisms to declare

and constrain limits of application).
