Compliance Process for Metal Assembled Engineering Vehicles under GB6675
Metal assembled engineering vehicles fall into the cross-category of metal toys and mechanical assembly toys. Due to their detachable small parts and metal coatings, their compliance process needs to focus on two key dimensions: mechanical physical safety and heavy metal migration. The following is the complete compliance process:
I. Pre-Compliance Preparation
1. Product Positioning and Standard Application
Applicable Standards: GB6675.1-2014 (Basic Specifications), GB6675.2-2014 (Mechanical and Physical Properties), GB6675.3-2014 (Flammability), GB6675.4-2014 (Migration of Specific Elements)
Age Range Determination: Generally applicable to children aged 3 and above; clear warning labels are required.
Product Feature Identification: Metal materials, screw/bolt connections, moving parts, coated surfaces
2. Internal Control Preparation
Organize product technical documents (design drawings, material lists, assembly processes)
Prepare raw material compliance certificates (metal sheets, coatings, inks)
Confirm that packaging and labeling designs meet standard requirements
II. Sample Submission Stage
3. Selection of Testing Institutions
Select a third-party testing institution with CNAS accreditation and CMA certification (e.g., Dezewei Testing CNAS registration number: L8083)
Confirm that the institution has toy testing capabilities to avoid limiting its selection.
4. Sample Preparation Requirements
Quantity: Typically 3-5 complete sets of samples (including all detachable parts) are required.
Status: Finished product, including packaging, instructions, and warning labels.
Model Coverage: If a series of models, representative samples or the entire series must be provided for testing.
III. Confirmation of Testing Items
5. List of Core Testing Items
Mechanical and Physical Properties (GB6675.2):
Small Parts Test (whether small parts are formed after detachment)
Sharp Points and Edges Test
Protrusions and Accessibility Test
Assembly Structure Strength Test (firmness of screws after repeated disassembly and reassembly)
Folding Mechanism and Hinge Test
Spring Mechanism Test (if applicable)
Drop, Impact, Pressure, and Tensile Tests
Chemical Properties (GB6675.4):
Migration of 8 soluble heavy metals in coatings (antimony, arsenic, barium, cadmium, chromium, lead, mercury, selenium) — Key Tests for Metal Toys
Substrate Heavy Metal Migration Test
Packaging Material Heavy Metal Test
Other Tests:
Flammability Performance (GB6675.3)
Labeling and Warning Statement Review (GB6675.1)
IV. Testing Implementation and Reporting
6. Testing Cycle and Process
Routine Testing Cycle: 5-7 working days (including retesting time)
Process: Application Acceptance → Sample Receipt → Document Review → Testing Implementation → Rectification of Non-conformities (if any) → Retesting → Report Issuance
7. Report Types
One-time Test Report (applicable to a single batch of products)
Series Model Report (covering different specifications within the same series)
V. Report Application and Subsequent Supervision
8. Compliant Application of the Report
Labeled on product packaging and promotional materials
For verification when entering e-commerce platforms and offline supermarkets
For handling random inspections by market supervision departments
9. Subsequent Supervision and Maintenance
Re-testing is required when raw material suppliers change.
A retesting assessment is needed to determine if process or design changes trigger retesting.
It is recommended to establish a regular sampling inspection mechanism (at least once a year).
Retain original reports for future reference, with a retention period of no less than 5 years.
VI. Common Non-Compliance Items and Recommendations
High-Frequency Non-Compliance Items for Metal Assembly Engineering Vehicles:
1. Risk of small parts falling off (loose screws, parts too small)
2. Excessive heavy metals in the coating (especially lead and cadmium)
3. Missing or incorrect warning labels on packaging (e.g., inappropriate age labeling)
4. Sharp edges not beveled
Compliance Recommendations:
Introduce a GB6675 standard checklist during the design phase.
Add anti-loosening design to screw connections (e.g., self-locking nuts).
Prioritize environmentally friendly coating processes (powder coating, electrophoretic coating).
Sign an annual technical service agreement with testing institutions to obtain early warnings of standard updates.
