ISO 9221-2:2015

Overview

ISO 9221-2:2015 - Furniture - Children’s high chairs - Part 2: Test methods - specifies standardized test procedures used to assess whether children’s high chairs meet the safety and performance requirements set out in ISO 9221-1. This second edition (2015) defines how to prepare a chair for testing, the test environment, required test equipment, and detailed test sequences for evaluating mechanical strength, stability, restraint systems and potential hazards.

Key topics and technical coverage

The standard focuses on practical, repeatable test methods rather than prescriptive design solutions. Major technical topics include:

• General test conditions - preparing a fully assembled chair, indoor ambient range (15 °C to 25 °C), and exclusion of convertible configurations for these tests.
• Test equipment - description of required apparatus such as test dummies, impact hammer, loading pads, beams, force-measuring devices, small parts cylinder and probes.
• Impact and durability tests - impact tests on seating areas and components; durability and strength testing of locking mechanisms and reclinable backrests.
• Restraint system evaluation - strength and attachment-point testing for harnesses, crotch restraints, waist belts/straps and slippage checks.
• Structural load tests - seat and footrest vertical static load tests; tray strength, vertical load, drop tests.
• Openings, small parts and shear/squeeze points - tests for gaps, leg openings, small parts cylinder checks and wedge-block tests to prevent entrapment.
• Backrest and lateral protection measurements - methods to determine backrest angle, height and lateral protection length/height.
• Stability tests - positioning and procedures to assess sideways, rearward and forward overturning risk, including tests of footrests and horizontal frame members.
• Test reporting - required information and results recording for conformity evidence.

Practical applications and users

ISO 9221-2:2015 is intended for:

• Manufacturers and product designers using repeatable test methods during design validation and pre-production verification.
• Independent testing laboratories performing compliance testing and producing test reports for certification or market surveillance.
• Regulators, retailers and procurement teams verifying safety claims and conformity with ISO 9221-series requirements.
• Quality and R&D teams integrating these methods into routine quality control and new-product development.

Using ISO 9221-2 helps ensure consistent, defensible safety testing of high chairs for children aged about 6 to 36 months, improving product safety and market acceptance.
