The new Chinese national standards GB6675 series (GB6675.1-2025 to GB6675.4-2025) will all come into effect on November 1, 2026. Early Childhood Education Audiobook GB6675 Testing Process (Including Electronic Component Requirements)
I. Core Preparations Before Testing (Targeted Review)
Precise Product Attribute Positioning
Age Group Determination (Directly Affects Test Items):
0-3 years: Must pass small component pull test (90N without detachment), battery compartment anti-accidental opening design (requires tools or double-action opening)
3-14 years: Small components allowed, but age warnings must be clearly marked (font ≥ 4-point boldface)
Electronic Function Confirmation:
Must simultaneously meet GB19865 "Electrical Toy Safety" (e.g., charging port anti-electric shock, circuit overload protection)
Sound Component Volume Limit: Sound pressure level ≤ 85 dB (A-weighted) at 10cm from the toy
Sample and Documentation List (3 more items than ordinary toys)
| Material Type | Specific Requirements
| Basic Sample | 3 complete finished products (including battery, charging cable, instruction manual), must be consistent with mass production
| Electronic Specific Documentation | Circuit schematic (with current-limiting resistor parameters labeled), battery supplier UN38.3 report, speaker power test report
| Structural risk document | Button/switch robustness design drawing (must indicate press life test data ≥ 5000 times), USB interface pull-out test record
II. Laboratory Testing Implementation (Moduled Disassembly)
Module 1: Mechanical and Physical Properties (Key Item for Audiobooks)
Key Test Items:
Small Parts Test
Test Objects: Buttons, volume knob, battery compartment cover, stickers (such as letter/number stickers)
Test Method: 90N tensile force for 10 seconds; parts must not detach (for products for 0-3 year olds)
Risk Case: 3D letter stickers may detach and lead to accidental swallowing
Drop and Impact Test
Conditions: Free fall from a height of 1.2 meters onto a hardwood board (1 drop on each of the 6 sides)
Pass Criteria: Battery compartment does not pop open, no short circuit, sound function is normal
Strap Safety
If with hanging rope: Length ≤ 30cm (to avoid entanglement risk), and tensile force ≥ 70N without breakage
Module 2: Electronic Safety (GB19865 Special Item)
Mandatory Test Items (Not applicable to ordinary toys):
| Test Items | Test Methods | Limit Requirements
| Electric Shock Protection | Probe Test (Simulating Child's Finger) | Charging Port Must Have Anti-Insertion Design (Hole Diameter ≤ 4mm)
| Operating Temperature | Measure Casing Temperature After 1 Hour of Continuous Playback | ≤ 45℃ (Avoid Burns)
| Battery Overcharge Protection | Apply 1.2 Times Rated Voltage for 24 Hours | Battery does not bulge or leak.
Module 3: Chemical Safety (Materials and Coatings Focus)
Key Focus Areas:
Printing Ink: Lead (Pb) migration ≤90mg/kg (for accessible colored illustrations)
Plastic Casing: Phthalate (6P total) ≤0.1% (especially soft PVC buttons)
Glue/Adhesive: Formaldehyde release ≤0.1mg/m³ (no odor residue when pages are turned)
Module 4: Combustion Performance (Paper/Fabric Components)
Book Pages: Vertical burning speed <100mm/min
Fluff Cover (if present): Flame spread time ≤30 seconds, with no molten drippings
III. Testing Cycle and Cost (Including Expedited Service)
Standard Process:
Total Cycle: 5-7 working days
Cost Breakdown:
Basic Testing Fee (Mechanical + Chemical): 1000-2000 RMB
IV. Report Review and Rectification (Common Problem Solving)
Key Report Page Check:
Must include CMA/CNAS dual certification, electronic testing standard number (GB19865-2021), age group determination criteria
Chemical tests must clearly list the specific values for lead, cadmium, and phthalic acid 6P (not just label "qualified").
V. Special requirements for e-commerce platform access
Documents to be uploaded to Tmall/JD.com:
Scanned copy of the test report (must include the section on electronic component testing)
3C certification certificate (if battery capacity > 18650mAh or input power > 15W)
Actual image with age warning (must be labeled "Contains small parts, not suitable for children under 3 years old")
