New ISO Method for Phthalates in Toys and Children's Products Published: ISO 8124-6:2014
A completely new method for phthalates in toys and children’s products has been published. It is based on a Chinese method and is intended to be used as a method standard in conformity assessments.
In August 2014, the International Organisation for Standardisation (ISO) published the completely new standard ISO 8124 Part 6 'Safety of Toys – Part 6: Certain phthalate esters in toys and children’s products'. The standard is largely based on the existing China national standard GB/T 22048-2008 ‘Toys and children's products - Determination of phthalate plasticizers in polyvinyl chloride plastic’
The new standard is part of a family of standards under the general title "Safety of Toys". In additional to the new part 6, the following parts have also been published:
- ISO 8124-1 "Safety aspects related to mechanical and physical properties"
- ISO 8124-2 "Flammability"
- ISO 8124-3 "Migration of certain elements"
- ISO 8124-4 "Swings, slides and similar activity toys for indoor and outdoor family domestic use"
The new standard part 6 specifies a method for the determination of 6 phthalates which are regulated under a number of legislative acts for toys and children’s products globally:
1. Di-n-butyl phthalate (DBP)
2. Benzyl butyl phthalate (BBP)
3. Bis-(2-ethylhexyl) phthalate (DEHP)
4. Di-n-octyl phthalate (DNOP)
5. Di-iso-nonyl phthalate (DINP)
6. Di-iso-decyl phthalate (DIDP)
The standard is applicable to toys and children’s products which are manufactured from plastics, textiles, and coatings etc. The methodology involves the use of the solvent dichloromethane as the extraction medium and gas chromatography with mass spectrometry as analytical method. It has also been validated for polyvinyl chloride (PVC), polyurethane (PU) and some representative coatings.
Highlights of the new standard are summarised in the following table.
BBP, DBP, DEHP, DIDP, DINP and DNOP in toys and children’s products
More than 1 sample may be used to obtain sufficient weight
Exemption from testing
< 10 mg material from 1 sample
Up to 3 similar materials in 1 test group allowed
Gas Chromatography Mass Spectrometry (GCMS)
