European foreword
This document (prEN 16261-3:2021) has been prepared by Technical Committee CEN/TC 212
“Pyrotechnic articles”, the secretariat of which is held by NEN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 16261-3:2012.
In comparison with the previous edition, the following technical modifications have been made:
— Addition of balances with different accuracies to clause 5.6;
— Clause 6.10.3 has been technically revised;
— A clause 6.12 on the use of detonative explosives has been added.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports essential requirements of Directive 2013/29/EU on the
harmonisation of the laws of the Member States relating to the making available on the market of
pyrotechnic articles.
For relationship with Directive 2013/29/EU, see informative Annex ZA, which is an integral part of this
document.

4 Test environment for functioning test
4.1 General
A large unobstructed area, which shall be wide open. The measuring points shall be positioned
appropriately for the type of measurement being carried out.
For aquatic fireworks, a water test area shall be available for testing the resistance to moisture and
functioning in the expected manner.
