【CE认证】智能体重称CE认证怎么做测试 智能体重称CE认证怎么办理证书【费用 周期 机构 报价】
智能体重秤CE认证需通过以下测试并完成流程：
一、核心测试项目
电磁兼容性(EMC)：依据EN 55014-1/2标准，测试辐射发射和抗干扰能力，确保在复杂电磁环境中稳定工作。
低电压指令(LVD)：按EN 60335标准进行电气安全测试，包括绝缘电阻（≥2MΩ）、耐压测试（如双重绝缘需3750V/1分钟）等。
计量准确性：根据OIML R76-1标准，用标准砝码验证称重误差（如1000g需在999.5g-1000.5g之间）。
材料安全：外壳需通过阻燃测试，电路板焊料需符合RoHS无铅标准。
防水性能（如适用）：按IP等级测试，模拟不同环境下的防水效果。
二、办理流程
准备资料：产品说明书、电路图、元件清单、技术文件等。
提交申请：向认证机构提交样品及资料，确认适用指令（如EMC、LVD、RoHS）。
实验室测试：完成EMC、LVD等测试，周期通常4-6周。
审核发证：通过后颁发CE证书，产品贴CE标志。
三、注意事项
无线功能需额外符合RED指令。
技术文件需保存10年备查。
认证费用因产品复杂度而异，建议提前规划预算。
The CE certification of intelligent weighing scales requires passing the following tests and completing the process:
1、 Core testing projects
Electromagnetic compatibility (EMC): According to the EN 55014-1/2 standard, the radiation emission and anti-interference ability are tested to ensure stable operation in complex electromagnetic environments.
Low Voltage Directive (LVD): Electrical safety testing shall be conducted in accordance with EN 60335 standard, including insulation resistance (≥ 2M Ω), withstand voltage testing (e.g. 3750V/1 minute for double insulation), etc.
Measurement accuracy: According to OIML R76-1 standard, use standard weights to verify weighing errors (such as between 999.5g-1000.5g for 1000g).
Material safety: The shell must pass flame retardant testing, and the circuit board solder must comply with RoHS lead-free standards.
Waterproof performance (if applicable): Test according to IP level and simulate the waterproof effect in different environments.
2、 Handling process
Preparation materials: product manual, circuit diagram, component list, technical documents, etc.
Submit application: Submit samples and materials to the certification body to confirm the applicable directives (such as EMC, LVD, RoHS).
Laboratory testing: Complete EMC, LVD, and other tests, with a typical cycle of 4-6 weeks.
Audit and certification: Upon approval, a CE certificate will be issued and the product will be affixed with the CE mark.
3、 Precautions
Wireless functionality requires additional compliance with the RED directive.
Technical documents need to be kept for 10 years for future reference.
The certification fee varies depending on the complexity of the product, and it is recommended to plan the budget in advance.
