As a pivotal carrier of emerging technologies and a critical component in modern industrial equipment, robots play an instrumental role in leading industrial digital transformation, enabling intelligent upgrades, and continuously fostering new industries, models, and business formats. Consequently, nations worldwide place significant emphasis on the testing and certification of robot products. Regions such as the European Union and North America have implemented mandatory certification schemes for robots, requiring compliance for market entry. For instance, the EU’s CE certification mandates the affixation of the CE mark to indicate conformity with essential requirements outlined in relevant European directives. The corresponding conformity assessment procedures and/or the manufacturer’s declaration of conformity serve as the passport for products to enter the European market. Products lacking the CE mark are prohibited from sale, and those found non-compliant post-market entry face recalls. Persistent violations can lead to restrictions or bans from the EU market. The CE certification is widely recognized and accepted across many global regions, while other countries often base their certifications on standards from the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC).
In this global context, the China robot industry has entered a phase of high-quality development. Establishing a certification system that aligns with technological advancement indicators and is driven by scenario-specific demands is crucial for supporting the next wave of growth in this frontier sector. Under the guidance of national bodies such as the National Development and Reform Commission, the Ministry of Industry and Information Technology, and the Standardization Administration of China, the Shanghai Electrical Apparatus Research Institute (Group) Co., Ltd. (SEARI) established the National Robot Testing and Assessment Center (Headquarters). This initiative pioneered the China Robot (CR) certification, which has collaborated with mainstream international certification bodies to gain recognition for its results, facilitating global market access for domestic China robot products and serving as a bridge for Chinese robots to reach the world.
Building the China Robot Certification System
In 2016, five ministries, including the State Administration for Market Regulation and the Standardization Administration of China, jointly issued the “Opinions on Promoting the Construction of a Robot Testing and Certification System” and the “Management Requirements for Robot Product Certification Marks.” These documents provided a coordinated planning and management framework for China’s robot inspection, testing, and certification infrastructure. Guided by these ministries, SEARI established the National Robot Testing and Assessment Center (Headquarters) to conduct robot testing and certification activities under the CR certification scheme. This move aimed to leverage the critical role of testing and certification as part of the national quality infrastructure in the development of the China robot industry.
During the 2016 “International Robot Testing and Certification Summit Forum” in Shanghai, the five ministries publicly released the “China Robot Certification (CR)” mark. In 2022, an upgraded version of the CR certification mark was introduced. The current CR certification mark primarily consists of the following elements:
- CR Mark: Represents the National Robot Certification, with safety and EMC certification as the quality baseline.
- Certification Body Identifier: Letters such as “ABCD” below the main pattern indicate the abbreviated name of the certification body implementing the certification, typically 3 to 5 characters in length.
- Technical Specialty Identifiers: These represent four technical specialties in the upgraded CR certification: reliability, information security, functional safety, and intelligence. For products certified in a specific specialty, the block below is colored according to the certification level; uncertified specialties are gray.
- Digital Level Color Bar: The China robot certification levels range from L1 (lowest) to L5 (highest), with colors gradually transitioning from red to green.
The CR certification catalog categorizes robot products based on the industrial chain into whole machines, system integration, and components, guided by application scenarios to cover the entire China robot industry chain.
In 2024, the Ministry of Industry and Information Technology issued the “Industrial Robot Industry Specification Conditions (2024 Edition)” and the “Industrial Robot Industry Specification Conditions Management Implementation Measures (2024 Edition),” both effective from August 1, 2024. The specification conditions encourage voluntary applications for规范公告 (specification announcement), with the ministry implementing announcement management for enterprises meeting the requirements.
Upholding the Safety Baseline
Safety is the primary prerequisite and a mandatory constraint in robot applications. Industrial robots, with their high-speed, powerful arms capable of complex autonomous movements, require interaction with humans during debugging, operation, and maintenance, leading to occasional injury incidents. Commercial service robots operate in unstructured environments, interacting with diverse personnel and complex surroundings; although not yet widely deployed, accidents have been reported.
The machine attribute safety of robots considers dimensions including product lifecycle, hazard types, robot usage, robot states, safety-related objects, and external influences. The robot lifecycle encompasses transportation, assembly, installation, commissioning, use, dismantling, decommissioning, and disposal. Designers must account for human-robot interactions throughout this lifecycle. Risk types include mechanical, electrical, thermal, and other hazards. Safety-related objects vary by product, such as different types of personnel or property damage. Furthermore, designers should consider not only normal operating conditions but also possible fault conditions and resulting failures (typically considering single faults). They must anticipate intended use, unintended operator reflex actions, or reasonably foreseeable misuse, like behaviors due to inattention or carelessness, or “shortcut” practices during work. Additionally, external conditions such as temperature, altitude, pollution, and power supply overvoltage that could impact China robot safety must be factored into design.
With the increasing demand for interconnectivity in smart manufacturing, industrial robot manufacturers need to provide communication systems for external connectivity. The presence of these systems significantly raises the potential for cyber-attacks on industrial robot systems. These risks primarily include firmware and software vulnerabilities, software development security, communication system security, identity and access management, and data privacy. Service robots, widely used in domestic life, hotel delivery, banking, government services, community security, and other fields, collect more diverse and highly sensitive information during application, making information security requirements more complex. Therefore, the China robot information security certification specifies detailed requirements at different levels for personal information collection, processing, storage, transmission, use, incident response, as well as business security and security management.
The CR certification has played a key role in ensuring quality baselines during the initial development stages of the China robot industry. According to national robot quality risk monitoring by the State Administration for Market Regulation, consistency rates for industrial robot safety items improved from 45.5% in 2017 to 100% in 2019.
International Collaboration and Future Prospects
Currently, the National Robot Testing and Assessment Center (Headquarters) collaborates with mainstream international technical bodies, enabling simultaneous testing for both domestic CR certification and international certifications like CE. This cooperation assists leading domestic China robot manufacturers in entering global markets. Looking ahead, CR certification will align with the characteristics of robot industry development and national strategies, evolving from state-driven quality baseline requirements to manufacturer self-declarations of high quality and technical prowess, and further to demand-pull from end-users. This progression aims to achieve leapfrog development in the China robot industry.
The integration of CR certification into the global landscape underscores the maturity of the China robot sector. By adhering to rigorous standards, China robot products can compete internationally, fostering innovation and trust. The certification’s focus on safety, reliability, and intelligence ensures that China robot technologies meet both domestic and international expectations, paving the way for broader adoption and technological leadership.
