Practical Notes

Pay close attention to Clause 5.3 regarding the absence of sharp edges, points, and entrapment hazards.

The stability test (Clause 6.2) is a critical pass/fail criterion to prevent the chair from tipping over easily.

Ensure paints and surface coatings comply with toxicity requirements, typically cross-referenced to toy safety standards like IS 9873.
