ST2016 Part 3: Chemical Properties.

Primary Objective:

To control the chemical risks associated with toys intended for children under the age of 14, limit the content of harmful chemicals, and prevent injuries such as poisoning and skin irritation. This standard aligns with ST2012 chemical requirements.

Standard Definition:

Applicable to toys and components intended for use by children under the age of 14 (including coatings, fill materials, textiles, plastics, etc.).

Key Terms: Harmful chemicals refer to substances such as heavy metals, formaldehyde, phthalates that may be present in toys and pose potential risks to children's health.

Testing and Certification Requirements

(1) Core Testing: Heavy Metal Detection: Controlsoluble lead, arsenic, cadmium, and eight other major heavy metals. Requirements for limits must be met.

Specific Substance Control: Polyvinyl Chloride (PVC) materials must be tested for phthalate content; textiles must be tested for formaldehyde content.

Migration Testing: Indicators such as color substance migration, evaporative residues, and potassium permanganate consumption must meet standards.

Test Methods: Formaldehyde testing usesan acetate ammonium buffer solution method (standardized in version 2016).

(2) Certification Compliance: Testing institutions must be third-party laboratories recognized by JTA.

Marking: Products that meet the standards can be marked with the ST logo (voluntary, valid for 4 years).

Obligations: Materials must be clean and free of contaminants, and comply withlimit requirements. Test reports must be retained for reference.
