Compliance overview
Scope and applicability
This standard applies to the electrical, electronic, and programmable electronic equipment and systems of construction machinery (including groups of machines working together) with a nominal voltage not exceeding 1000V a.c. or 1500V d.c. and a rated frequency up to 200Hz. It is designed to be used in conjunction with GB 5226.1-2008. This standard is mandatory for manufacturers of construction machinery entering the Chinese market. It does not cover additional requirements for machinery used in explosive atmospheres or processing explosive materials.
Technical requirements
The standard specifies comprehensive safety and technical conditions for the electrical equipment of construction machinery. Key areas include basic requirements for equipment selection and environmental operating conditions (e.g., EMC, temperature, humidity, altitude). It mandates specific configurations for power supply introduction and disconnect switches, ensuring safe isolation and protection against unauthorized operation. The standard details electric shock protection and overcurrent protection mechanisms for various circuits (power, control, lighting). It includes specific requirements for lightning and switching surge protection (LEMP), mandating the use of Surge Protective Devices (SPDs) and proper grounding to prevent system failure. For control circuits, it outlines requirements for wireless control and data transmission, emphasizing security, interference prevention, and safe stopping functions. Manufacturers must ensure that control functions remain safe even in the event of failures or faults. The standard also covers wiring practices, motor selection, and the provision of adequate technical documentation and warning labels.
Testing methods
Compliance verification involves several testing methods, primarily referenced from GB/T 28554-2012 and various ISO standards. Key tests include Electromagnetic Compatibility (EMC) testing, which covers broadband and narrowband radiated emissions, as well as immunity to electromagnetic radiation, electrostatic discharge (ESD), and transient conduction. The standard also references procedures for verifying the proper functioning of emergency stop devices and control circuit integrity under fault conditions. Additionally, it provides guidelines for lightning risk assessment and the verification of lightning protection measures, including grounding resistance and equipotential bonding checks.
FAQs
What products are regulated under GB 5226.6-2014?
This standard regulates the electrical equipment of construction machinery, including earthmoving equipment, foundation drilling rigs, concrete machinery, road construction machinery, and maintenance equipment, provided their nominal voltage does not exceed 1000V a.c. or 1500V d.c.
Is GB 5226.6-2014 mandatory?
Yes, most chapters of this standard are mandatory for the relevant electrical equipment of construction machinery sold in China. Only a few chapters dealing with general recommendations are non-mandatory. Compliance is essential for market access.
How does GB 5226.6-2014 relate to other standards?
This standard is Part 6 of the GB 5226 series and is designed to be used alongside GB 5226.1-2008 (General requirements). It also references numerous other GB/T and ISO standards for specific components, testing methods, and safety principles.
