European foreword
This document (prEN 15767-3:2025) has been prepared by Technical Committee CEN/TC 192 “Fire
service equipment”, the secretariat of which is held by BSI.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 15767-3:2010.
— the title has been amended;
— definition of “foam nozzle” has been added (see 3.3.1);
— “foam cannon” has been replaced with “foam tube” (see 3.3.2);
— maximum flow Q , has been deleted;
max
— according to current rules for drafting standard, notes containing the words “should” and “may” have
been transformed into normative text;
— all general requirements have been placed in a new 4.1 “General”;
— information about the viscosity of the foam concentrate shall be given (see 4.1 and 5.1.2);
— each verification has been placed under the corresponding requirement (see Clause 4);
— water nozzles shall be ergonomically designed (see 4.1 – should replaced by shall);
— missing requirements have been added in 4.4.5 and 4.4.6;
— missing verification have been added in 4.2.1, 4.2.2, 4.2.3, 4.2.4 and 4.3;
— Table 1 “Maximum mass” has been amended;
— informative Annex A on “Effects of the foam concentrate on the performance of the foam devices” has
been deleted;
— improvement of the wording/editorial changes.
1 Scope
In addition to the requirements given in EN 15767-1, this document applies to devices designed for
aspirating air and projecting low expansion foam and, in some cases, inducting foam concentrate. It
specifies requirements for safety, performance, classification and designation, as well as test methods,
instructions for use and maintenance and marking.
This document is not applicable to water nozzles that are manufactured before its date of publication.
2 Normative references
The following documents are referred to in the text in such a way that some or all of their content
constitutes requirements of this document. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any amendments) applies.
