other  : Safety  
4. Products covered (HS or CCCN where applicable, otherwise national tariff 
heading. ICS numbers may be provided in addition, where applicable):  Fire-
fighting (ICS code(s): 13.220.10)  
5. Title, number of pages and language(s) of the notified document:  BOS ISO 7203 -
1 :2019, Fire extinguishing media — Foam concentrates — Part 1: Specification for low -
expansion foam concentrates for top application to water -immiscible liquids; (45 page(s), 
in English)  
6. Description of content:  This document specifies the essential properties and 
performance of liquid foam concentrates used to make low -expansion foams for the 
control, the extinction and the inhibition of reignition of fires of water -immiscibl e liquids. 
Minimum performance on certain test fires is specified.  
These foams are suitable for top application to fires of water -immiscible liquids. The foams 
that conform with ISO 7203 -3 are also suitable for top application to fires of water -
miscible li quids.  
The foam concentrates can be suitable for use in non -aspirating sprayers or for subsurface 
application to liquid fires, but the requirements specific to those applications are outside 
the scope of this document.  G/TBT/N/BWA/135
