According to the EU RoHS Directive (2011/65/EU and amendments), sprayers containing electronic components (such as electric drive units, batteries, etc.) are subject to mandatory testing. The following is a detailed process and key points, compiled from the latest industry practices and official requirements:
I. Confirming Product Suitability
1. Necessity of Testing
- Electric sprayers (such as water replenishment sprayers and disinfectant spray guns) fall under the RoHS directive's category of small household appliances or power tools and are subject to mandatory testing.
- Exception: Purely mechanical sprayers (without circuitry or batteries) do not require testing.
II. Prepare Testing Materials
The following documents and samples must be provided to the laboratory:
| Material Type | Specific Requirements
| Technical Documents | Circuit Schematics, Product Manual, and Parts List (BOM)
| Test Samples | 2-3 complete devices, including all material components (plastic housing, battery, nozzle, circuit board, etc.)
| Material Separation Requirements | Classify testing by homogeneous material (e.g., metal nozzle, plastic handle, wire insulation, etc.)
| Chemical Sample Size | 10-20g per type for non-metallic materials and 5-10g per type for metal materials
III. Testing Process and Standards
1. Selecting a Certification Body
- Must be certified by an EU-recognized third-party laboratory (e.g., Dezewei Testing).
2. Test Items and Limits
| Hazardous Substances | Metal Limits | Non-metal Limits | High-Risk Components of Sprayers
| Lead (Pb), Mercury (Hg), etc. | ≤1000ppm | ≤1000ppm | Solder Joints, Batteries
| Cadmium (Cd) | ≤100ppm | ≤100ppm | Coatings, Plastic Pigments
| Phthalates (4 types) | - | ≤1000ppm | Soft Plastic Handles, Seals
3. Test Method
- XRF Scanning for Preliminary Screening + Chemical Solvent Extraction for Precise Quantification.
IV. Issuance of RoHS Compliance Documents
1. Test Report
- List all material test data, including the laboratory authorization number and test date.
2. Declaration of Conformity (DoC)
- Signed by the manufacturer or importer, stating that the product complies with RoHS 2.0 requirements.
V. Lead Time and Cost Reference
| Project | Description
| Lead Time | 5-7 business days for standard products (qualified samples and complete documentation)
| Cost | 1,000-3,000 RMB, charged by material type and quantity (a comprehensive report is more economical than a full-unit test)
Key Considerations
1. Battery Module Specialty Testing
- Sprayers containing lithium batteries require additional testing for lead and cadmium migration.
2. Packaging Material Compliance
- Product packaging (such as plastic film and printing ink) must also comply with RoHS limits.
3. Common Failure Causes
- Excessive phthalate content in plastic parts (excessive plasticizer addition);
- Hexavalent chromium content in the coating on metal parts.
Optimization Suggestions
1. Pre-inspection and Corrective Action: Choose a laboratory that offers a "pre-inspection + corrective action plan" to avoid repeated sampling (if excessive DEHP content in plastics is found, the plasticizer can be replaced).
2. Supply Chain Management: Require suppliers to provide RoHS reports for raw materials to reduce the risk of full-unit testing. Note: RoHS certification has no official expiration date, but retesting is required after any material or design changes.
We recommend contacting a CPSC-authorized laboratory (such as Dezewei ID: 1552) directly for a customized solution to ensure first-time approval.
