Fireworks — Test methods for determination of specific chemical substances — Part 11: Phosphorus content by inductively coupled plasma optical emission spectrometry (ICP-OES)

This document specifies the test method for the determination of phosphorus content in firework compositions by inductively coupled plasma optical emission spectrometry (ICP-AES). Such test is applied to fireworks excluding Christmas crackers, party poppers, or snaps according to ISO 25947-5. The use of white phosphorus can lead to fireworks of hazardous chemical stability that can be detected by possible self-ignition during the thermal conditioning test according to ISO 25947-4:2017, 6.16 (75,0 ± 2,5 °C for 48 h).

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

compositions by inductively coupled plasma optical emission spectrometry (ICP-AES).
Such test is applied to fireworks excluding Christmas crackers, party poppers, or snaps according to
ISO 25947-5. The use of white phosphorus can lead to fireworks of hazardous chemical stability that can
be detected by possible self-ignition during the thermal conditioning test according to ISO 25947-4:2017,
