GB/T 45367-2025 Textiles - Determination of camphor derivates
WARNING - Persons using this standard shall be familiar with normal laboratory practice. This document does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user to establish appropriate safety and health practices and to ensure compliance with any national regulatory conditions.
1 Scope
This document describes a test method for the determination of camphor derivates (3-benzylidene camphor and 4-methylbenzylidene camphor) in textiles using liquid chromatography-tandem mass spectrometry (LC-MS/MS).
This document is applicable to all kinds of textiles.
2 Normative references
The following documents contain requirements which, through reference in this text, constitute provisions of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

GB/T 8170 Rules of rounding off for numerical values & expression and judgment of limiting values
3 Terms and definitions
No terms or definitions are listed in this document.
4 Principle
The specimens are subject to methanol ultrasonic extraction. The extract is filtered through membrane, determined by LC-MS/MS, and quantified with the external standard method.
