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).
