In response, the National Development and Reform Commission, the General Administration of Quality Supervision, Inspection and Quarantine, the Ministry of Industry and Information Technology, and the Certification and Accreditation Administration jointly launched the China Robot (CR) Certification on November 2, 2016, during the International Robot Testing and Certification Summit Forum. This voluntary certification scheme represents the first comprehensive national certification for robot products in China, focusing on safety, electromagnetic compatibility (EMC), performance, functional safety, environmental adaptability, and reliability. The initiative aims to regulate the market, enhance consumer confidence, and promote the sustainable growth of the China robot industry.
The CR certification mark serves as the unified identifier for certified robot products, symbolizing compliance with stringent national standards. Since the introduction of the certification implementation rules, dozens of enterprises have successfully obtained certification, marking a significant step forward for the China robot market. This certification is pivotal for ensuring that China robot products meet high-quality benchmarks, thereby fostering trust among users and facilitating international trade. The certification process is designed to be thorough, covering all aspects of a robot’s lifecycle, from design and manufacturing to deployment and maintenance.
Comprehensive Scope of the China Robot Certification
The CR certification encompasses a wide range of robot products, divided into two primary categories: industrial robots and service robots. This broad scope ensures that various types of China robot products are subjected to rigorous evaluation.
- Industrial Robots: The certification rules for industrial robots are based on the definition provided in GB/T 12643-2013, “Robots and Robotic Devices – Vocabulary.” Certification assesses safety and EMC according to factors such as usage precautions, hazard levels, risk conditions, electromagnetic interference, basic safety design, protective measures, usage information requirements, and reliability criteria. This ensures that industrial China robot products operate safely and efficiently in manufacturing and other industrial environments.

Certification Modes and Process Overview
Manufacturers seeking CR certification for their China robot products can choose from two distinct certification modes, depending on their needs and product lifecycle strategies.
- Mode A: Product Type Testing – This mode is suitable for single products or limited batches. The certificate is valid only for the specific product tested, with the product serial number included on the certificate. It does not have an expiration date, making it ideal for prototypes or custom China robot solutions.
- Mode B: Product Type Testing + Initial Factory Inspection + Post-Certification Surveillance – This comprehensive mode is designed for mass-produced China robot products. The product certificate is valid for five years, with ongoing validity maintained through regular post-certification supervision. This mode ensures continuous compliance and quality assurance throughout the product’s market life.
The certification process involves several critical stages: certification application, type testing, initial factory inspection (for Mode B), evaluation and approval of certification results, post-certification supervision (for Mode B), and re-examination. Each stage is meticulously designed to verify that China robot products meet all required standards.
Detailed Certification Application Procedures
When applying for CR certification, manufacturers can opt for safety certification, EMC certification, or a combined safety and EMC certification. The division of certification application units follows specific principles: products of the same basic model from the same production site constitute one application unit; products from different production sites are treated as separate units. Type testing is typically conducted on samples from one production site, but other sites may be required to provide samples and documentation for consistency checks.
The application materials required for China robot certification are comprehensive to ensure thorough evaluation. These include:
- A formal application form detailing the China robot product specifications;
- A factory inspection questionnaire (specifically for initial Mode B applications);
- A detailed product description outlining the design and functionality of the China robot;
- Registration documents for the applicant, producer, and manufacturer, such as business licenses or organization code certificates (for initial applications);
- Contracts between sellers and producers or importers and producers (if the applicant is a seller or importer);
- A power of attorney for an agent, if applicable;
- Valid supervision inspection reports or factory inspection reports, if available from previous certifications;
- Technical documentation including overall assembly diagrams, electrical schematic diagrams, and product manuals for the China robot;
- Electrical parameter tables specifying the operating conditions of the China robot;
- A list of key components and parts used in the China robot, highlighting safety-critical elements;
- An explanation of differences between various models within the same application unit, ensuring clarity in certification coverage;
- A radio type approval certificate, if the China robot product incorporates radio transmission functions;
- Any other documents deemed necessary by the certification body to assess the China robot product fully.
For modifications post-certification, certificate holders must submit a change application for any alterations in certificate content, product design or structure, key components, or applicable standards. The certification body evaluates these changes and may require additional testing or factory inspection. This rigorous process ensures that any evolution in China robot products maintains compliance with certification requirements.
Test Sample Requirements for China Robot Certification
For series products under a single application unit, representative models are selected for testing. The samples should ideally cover all safety and EMC requirements of the series. If the representative model cannot fully cover these requirements, additional models from the series must be tested to address gaps. Typically, one set of samples is required for the representative model, with supplementary samples and tests determined based on the extent of coverage needed. This approach minimizes testing redundancy while ensuring comprehensive evaluation of China robot products. After testing, all records and samples are retained by the testing and certification bodies, with sample disposal agreed upon between the certification agency and the enterprise.
Type Testing and Reporting Timeline
The type testing period for China robot products generally spans 20 working days, during which samples undergo rigorous assessment against the reference standards. If products fail to meet the standards, manufacturers are allowed to make modifications and resubmit samples for re-testing within a six-month period. The number of samples and specific test items for re-testing are determined by the testing agency based on the nature of the non-compliance. This flexibility supports continuous improvement in China robot product quality while upholding certification integrity.
Factory Inspection Protocols and Duration
Factory inspections are a core component of the CR certification, especially for Mode B. These inspections assess the manufacturer’s quality assurance capabilities and verify product consistency with the type-tested samples. Key areas of focus include:
- Verifying that certified China robot products match the type test reports in terms of identification, structure, and key components;
- Ensuring that production processes align with certified specifications;
- Conducting on-site witness testing of safety performance, where applicable.
For multi-series China robot products, at least one model from each series is inspected to ensure broad consistency. Initial factory inspection usually occurs after successful type testing, but both can be conducted simultaneously if necessary. The inspection must be completed within one year of type testing; otherwise, type testing must be repeated. The duration of the initial factory inspection depends on the production scale, as outlined in the table below, which is crucial for planning and resource allocation in the China robot industry.
| Production Scale | Below 100 Employees | 100 Employees or Above |
|---|---|---|
| Duration (person-days for initial/surveillance/re-examination inspection) | 2/1/2 | 4/2/3 |
If a factory inspection reveals non-conformities, the manufacturer has 40 working days to rectify them. The certification body then verifies the corrections. Failure to rectify issues or persistent non-compliance results in a failed inspection. Upon successful evaluation of both type testing and factory inspection, the certification body issues the CR certificate, typically within 30 days. If type testing fails or factory inspection is unsuccessful, certification is terminated, and a new application is required for future attempts, underscoring the stringent nature of the China robot certification process.
Certificate Management: Suspension, Revocation, and注销
The CR certification framework includes provisions for managing certificates throughout their validity period. Certificates may be suspended under specific circumstances, such as when supervision results indicate non-compliance that does not warrant immediate revocation, or if the certificate holder misuses the certification mark. Suspended certificates can be reinstated after corrective actions are verified. Conversely, certificates may be revoked for more severe issues, including sustained non-compliance, serious quality degradation, fraudulent use of certification, or refusal to undergo supervision. Revocation bars the holder from reapplying for one year. Additionally, certificates may be注销 if the holder no longer produces the certified China robot products or voluntarily withdraws due to changes in certification rules. These measures ensure the ongoing credibility of the China robot certification scheme.
Strategic Implications for the China Robot Industry
The launch of the CR certification has profound implications for the China robot industry, driving it toward higher standards of quality and safety. By addressing common pitfalls such as inadequate risk assessment and weak component control, the certification enhances the reliability and performance of China robot products. This, in turn, boosts consumer confidence and facilitates market acceptance, both domestically and internationally. For manufacturers, obtaining CR certification serves as a competitive advantage, signaling commitment to excellence and compliance with national regulations. The emphasis on electromagnetic compatibility ensures that China robot products can operate seamlessly in diverse environments without causing interference, a critical factor in today’s interconnected world. Furthermore, the focus on functional safety, particularly in emergency systems, reduces accident risks and fosters safer human-robot interaction.
Industry stakeholders have widely welcomed the CR certification, recognizing its alignment with global best practices and its potential to elevate the standing of Chinese robot manufacturers on the world stage.
