Toy Safety Test Items: MS ISO 8124 and the 8 Heavy Metals (Malaysia)

Toy safety testing in Malaysia centres on MS ISO 8124, covering three major areas: mechanical and physical safety (8124-1), flammability (8124-2), and chemical safety (8124-3, including the migration of 8 heavy metals). MS ISO 8124-1 (2018) applies to toys for children under 14; flammability and chemical safety have their own corresponding sub-standards. This article explains what is tested in each area and why, as well as what to watch out for when a toy contains components such as electric parts, magnets or button batteries. (For the full overview, see the Malaysia toy safety certification and labelling guide.)

The three test areas at a glance

Mechanical and physical (8124-1)

This is the part closest to everyday play situations, targeting whether the toy's structure itself can cause injury:

• Small parts: whether there are parts a young child could swallow—directly corresponding to choking risk.
• Sharp points and edges: to avoid puncture and cuts.
• Cord/strap length: overly long cords/straps carry entanglement and strangulation risk.
• Projectile kinetic energy: for toys that launch projectiles, the kinetic energy must be within a safe range to avoid eye injury.
• Structural strength: whether the toy breaks under force, producing new small parts or sharp edges.

MS ISO 8124-1 (2018) applies to toys for children under 14 and is the baseline for mechanical and physical safety.

Flammability (8124-2)

This tests the burning rate of materials, to ensure the toy does not spread flame quickly when it contacts a fire source—especially important for toys made of plush, cloth dolls, masks, dress-up costumes and other materials that are close to the body or cover a large area.

Chemical: migration of 8 heavy metals (8124-3)

The focus of chemical safety is the migration of 8 heavy metals—that is, the amount that could dissolve out and be absorbed by the body when a child puts the toy in their mouth and bites it—each with a maximum permissible value. The 8 heavy metals are:

"Migration" refers to the amount that can dissolve out and enter the body, not the total content in the material—which is why paints, inks and plastic formulations need particular attention.

High-risk components: usually additional requirements

Toys containing components such as electric parts, magnets or button batteries usually have additional requirements beyond the basic tests above:

• Magnets: swallowing multiple strong magnets can cause them to attract each other inside the intestines, causing serious injury.
• Button batteries: swallowing causes burns and chemical injury; securing and protecting the battery compartment is key.
• Electric parts: heat generation, electrical safety and the like must be assessed together.

These components also correspond to warnings on the label; for labelling practice, see how to label the recommended age and warnings.

Three things to think through before submitting for testing

For the same toy, the preparation before submission directly affects how smoothly testing goes and whether it must be redone:

• Fix the recommended age first: the age grade determines which test thresholds apply (for example, small-parts and chemical requirements are stricter for infants and toddlers). Without a fixed age, the test scope cannot be pinned down.
• Inventory materials and coatings: chemical testing looks at heavy-metal migration; paints, inks, plating and printed areas are often the sources of dissolution, so before submission, inventory which surfaces a child will touch or bite.
• Samples must be representative: what is tested is the "design type", so the submitted samples must be consistent with the mass-production version; if you later change materials or structure, the original report may no longer cover it and must be re-confirmed.

Why all three areas are indispensable

Mechanical/physical safety guards against injuries that "happen right away"—swallowing, puncture, strangulation, being struck; flammability guards against fire spread on contact with a flame; chemical safety guards against "long-term accumulation" of heavy-metal absorption. The three target completely different hazard types, so you cannot do just one and claim safety. This is also why SIRIM certification requires type testing to cover them completely.

How does testing connect to certification?

Passing the tests is only the first step; after obtaining a passing report, you use it to apply for the SIRIM Certificate of Conformity and complete labelling—see the SIRIM certification process. Imported batches must additionally cooperate with arrival inspection—see import toy checks.

Self-check checklist

• [ ] The applicable MS ISO 8124 sub-standard and recommended age confirmed (under-14 baseline)
• [ ] Mechanical/physical (small parts / sharp edges / cords / projectiles / strength) tested
• [ ] Flammability tested
• [ ] Chemical (migration of 8 heavy metals) meets the maximum permissible limits
• [ ] Additional assessment done for products containing electric parts / magnets / button batteries

Frequently asked questions (FAQ)

Q: Which standard applies to my toy? MS ISO 8124-1 (2018) applies to the mechanical and physical safety of toys for children under 14; flammability and chemical safety each have a corresponding sub-standard (8124-2, 8124-3), applied together according to the product's characteristics.

Q: What are the 8 heavy metals? Antimony (Sb), arsenic (As), barium (Ba), cadmium (Cd), chromium (Cr), lead (Pb), mercury (Hg), selenium (Se); what is tested is "migration"—that is, the amount that can dissolve out and be absorbed.

Q: Is "migration amount" the same as "total content"? No. Migration amount refers to the amount that can dissolve out of the material and enter the body; testing looks at whether the migration amount is within the maximum permissible value, not the total content in the material.

Q: Do toys with magnets or button batteries need extra testing? Usually there are additional requirements. Besides the basic tests, these high-risk components require assessment of risks such as accidental swallowing and electrical safety, and corresponding warnings on the label.

Summary

Toy testing = mechanical/physical + flammability + chemical (migration of 8 heavy metals), with MS ISO 8124 as the common baseline; products with high-risk components add further assessment.
