Firework powder is a core component of fireworks products, and its content of aluminum, magnesium, potassium, and barium directly affects the flammability of the product. Burning stability, optical color effect, and safety performance. Currently, the industry lacks a unified method for simultaneous multi-element determination, leading to inconsistent results from different testing institutions. The results are not comparable and cannot meet the needs of production control, quality supervision and import and export inspection. To address the aforementioned issues, standardize testing procedures, and ensure the quality and safety of fireworks and firecrackers, this document specifies the use of inductive... The content of aluminum, magnesium, potassium, and barium in pyrotechnic agents and raw materials was determined by intracytoplasmic plasma optical emission spectrometry (ICP-OES). Specifically, the content of aluminum and magnesium was... The testing method involves invention patent number ZL201410096991.8, and the patentee has committed to conducting the testing in a fair, reasonable, and non-discriminatory manner. (FRAND) principle provides for patent implementation licensing, and relevant licensing conditions can be obtained from the National Technical Committee on Standardization of Fireworks and Firecrackers (SAC/TC). 149) or obtained by the patentee. The purpose of this document is to provide the industry with scientific, accurate, and unified testing standards and to promote the standardized management of fireworks and firecracker product quality. The issuing organization of this document draws your attention to the fact that declarations conforming to this document may involve relevant patents related to the content in Chapters 5 and 6. The use of. The issuing organization of this document makes no position on the authenticity, validity, or scope of the patent. The patent holder has committed to the issuing authority of this document that he is willing to cooperate with any applicant on reasonable and non-discriminatory terms and conditions. Next, negotiations will be held regarding patent licensing. The patent holder's statement has been filed with the issuing agency of this document. The patent holders listed in Table 1 hold the patents covered in this document. Table

1 Scope

GB/T 47164-2026 is the Chinese national standard covering analysing a pyrotechnic composition - the metals that provide the light and the heat and the barium that colours it green and is toxic, quantified by ICP-OES to check the formulation against what is permitted. First edition, in force since 1 June 2026. It was issued on 27 February 2026 and has been in force since 1 June 2026, as a first edition. The document is under the responsibility of the China National Light Industry Council. This page is published from the official record of the 2026 edition; the clause text of a standard this recent is not yet in circulation, and the figures, limits and tables it contains are those of the document itself, delivered in full with the English translation.
