大家有这份标准吗？
ISO 22744 (all parts), Textiles and textile product — Critical substances potentially present in
components of textile product materials — Determination of organotin compounds
针对EN71-3有机锡假阳性问题，最新版的标准（EN71-3:2019）引用的有机锡测试方法由ISO/TS16179改为ISO22744。不知何因？
在ISO官网显示该标准还在草案阶段：
ISO/DIS 22744-1  Textiles and textile product -- Critical substances potentially present in components of textile product materials -- Determination of organotin compounds -- Part 1: Method using gas chromatography
Status :  Under development(询问阶段，DIS)
ISO/NP 22744-2 Textiles and textile product -- Critical substances potentially present in components of textile product materials -- Determination of organotin compounds -- Part 2: Direct method using LC/MS/MS
Status :  Under development（提案阶段，NP)
