How do I test if toy accessories pass the small parts cylinder test?

The small parts cylinder test determines whether toy accessories pose choking hazards by measuring if components can fit entirely within a standardised cylinder. This EN 71-1 test protects children under 36 months by identifying parts that could block airways. Toy accessories that pass remain completely outside the cylinder, whilst those that fit inside require age warnings or design modifications for EU market compliance.

What exactly is the small parts cylinder test and why do toy accessories need it?

The small parts cylinder test is a standardised safety assessment that evaluates whether toy accessories contain components small enough to create choking hazards for young children. This test uses a precisely dimensioned cylinder to simulate a child’s throat, determining if detached or detachable parts could potentially block airways.

Under EN 71-1 safety standards, this testing prevents serious accidents by identifying dangerous components before toys reach consumers. The regulation specifically targets toys intended for children under 36 months, as well as toys that may reasonably be expected to be used by children in this age group, who frequently explore objects by putting them in their mouths.

Common toy accessories requiring testing include:

Small figures and character pieces
Building blocks and construction elements
Craft components and art supplies
Detachable elements from larger toys
Game pieces and counters
Miniature accessories and props

The test becomes particularly important for manufacturers selling in the EU market, where compliance with toy safety standards forms part of broader product safety requirements. Any toy accessory intended for children under three years, or likely to be used by this age group, requires small parts cylinder testing to demonstrate safety compliance.

How do you properly conduct the small parts cylinder test step by step?

The small parts cylinder test follows specific procedures using standardised equipment with precise dimensions. The test cylinder measures 31.7mm in diameter and 57.1mm in depth, designed to replicate the dimensions of a young child’s throat.

Test Parameter	Specification
Cylinder Diameter	31.7mm
Cylinder Depth	57.1mm
Test Temperature	Room temperature (20°C ± 5°C)
Force Application	Reasonable force only

Step-by-step testing procedure:

Sample Preparation: Ensure toy accessory samples represent production quality and condition
Component Identification: Apply reasonable force to identify any components that could detach during normal use or foreseeable misuse
Individual Testing: Test each detachable component separately by attempting to insert it completely into the cylinder
Result Assessment: Document whether components fit entirely within the cylinder without applying excessive force
Documentation: Record all measurements, test conditions, and results with photographs showing component positioning

Components that slide completely inside fail the test and present choking hazards. Parts that remain partially outside, even when inserted as far as possible, pass the assessment. Maintain detailed testing records including product identification, test dates, operator details, and environmental conditions to support regulatory compliance.

What happens if toy accessories fail the small parts cylinder test?

Toy accessories that fail the small parts cylinder test cannot be marketed to children under 36 months without significant modifications or appropriate safety warnings. Failure means components fit entirely within the test cylinder, indicating potential choking hazards that require immediate attention before market placement.

Manufacturers who fail to meet safety standards face real consequences. The EU’s Safety Gate system publicly documents violations, creating a searchable record of companies whose products have been flagged as dangerous and removed from the market. This transparency mechanism serves as both a consumer protection tool and an incentive for manufacturers to prioritise safety compliance.

The regulatory landscape includes multiple layers of oversight. Organizations like BEUC (the European Consumer Organisation) supplement government enforcement by investigating complaints, testing products, and pushing for recalls when manufacturers fail to meet safety obligations. This multi-tiered approach ensures comprehensive protection for consumers whilst maintaining market standards.

Available options following test failure:

Solution	Action Required	Market Impact
Product Redesign	Enlarge components, secure parts permanently, eliminate problematic elements	Maintains original target age group
Age Restriction	Add “Not suitable for children under 36 months” warnings	Limits market to older children
Enhanced Labelling	Include specific choking hazard notifications	Requires prominent warning displays

Product redesign represents the most comprehensive solution, involving modifications that eliminate the hazard entirely. Alternatively, products can be remarketed with clear age warnings and specific choking hazard notifications in appropriate languages for target markets.

Retesting becomes necessary after any design modifications to verify improvements address the identified hazards. For EU market access, failed products without proper modifications or warnings face regulatory restrictions. Market surveillance authorities can prevent sale, require recalls, or impose penalties for non-compliant toys that pose safety risks to young children.

Understanding small parts testing requirements helps manufacturers develop safer toy accessories whilst maintaining market access. Proper testing procedures, accurate documentation, and appropriate responses to test failures ensure products meet safety standards and protect young users.
