4 Requirements and verification
4.1 General
All the tests defined in this document are type tests.
To compare the performance of the foam devices, all tests described in Clause 4 are run with water.
However, the performance with water is only a guide.
The following characteristics are influenced by the make and condition of the foam concentrate:
— effective throw;
— expansion;
— metering (percentage).
As much information as possible should be provided on the performance of foam devices for different
types of foam concentrates under operational conditions.
Unless otherwise specified, tests shall be at the reference pressure p , in the following order, on foam
R
tubes, self-inducting nozzles and foam attachments.
NOTE Guidance for acceptance tests on delivery is given in Annex A.
The instruction handbook of self-inducting nozzles shall specify the conditions of use in respect of
EN 1568-1:2018 characteristics. At least the maximum viscosity of the foam concentrate shall be given.
Design data and documentation shall be given in the instruction handbook (see Clause 5).
Foam nozzles shall be ergonomically designed so that they can be easily operated without risk of injury
when wearing firefighter's gloves complying with EN 659.
4.2 Mechanical characteristics
4.2.1 Mass
The foam device shall have a maximum mass as specified in Table 1. The maximum mass does not apply
to seawater-resistant foam devices.
