Scope

This document describes a method for the determination of formamide in toy materials
using high performance liquid chromatograph-mass spectrometer.
This document is applicable to the determination of formamide in foam materials such
as ethylene-vinyl acetate copolymer (EVA), polyethylene (PE), chemically cross-linked
polyethylene (XPE), and polyvinyl chloride (PVC) in toy products. It is used as a
reference for the determination of formamide in other foam materials.
