1 Scope
This standard specifies the method for detecting extractable allergenous disperse dyestuffs (see Annex A) on textiles with high performance liquid chromatography - mass spectrometer (LC/MS) or high performance liquid chromatography - diode array detector (HPLC/DAD).
This standard is applicable to printed and dyed textiles.
2 Normative References
The following normative documents contain provisions which, through reference in this text, constitute provisions of this standard. For dated references, subsequent amendments (excluding corrections), or revisions, of any of these publications do not apply to this standard. However parties to agreements based on this standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the normative document referred to applies.

3 Theory
After the sample was extracted with methanol, subject the extract to qualitative and quantitative determination with the high performance liquid chromatography - mass spectrometer (LC/MS) or the high Performance liquid chromatography - diode array detector (HPLC/DAD), and where necessary, thin layer chromatography (TLC) and infrared spectrometry (IR) may be adopted to facilitate the qualitative analysis of extract liquor.
