This standard is under the jurisdiction of the China Elevator Association, and is jointly compiled by the National Elevator Quality Inspection and Testing Center and domestic door protection device manufacturers. It is applicable to various door protection devices matched with elevator car doors, landing doors, and escalator entrances and exits, covering the whole life cycle management of device design, production, inspection, installation, operation and maintenance. The core contents of the standard include: first, establishing the classification system of door protection devices, dividing them into three categories: photoelectric type (light curtain), mechanical type (safety edge), and composite type according to the working principle, and three categories: full-height type, half-height type, and entrance special type according to the protection range, and clarifying the applicable scenarios and core functional requirements of different types of devices; second, refining the core performance technical requirements, clarifying the mandatory indicators of the protection range, response time, detection accuracy and minimum detectable object size of the door protection device, stipulating that the response time of the photoelectric door protection device is no more than 20ms, the minimum detectable object size is no more than 10mm, and formulating special performance requirements for children and small object detection scenarios; third, improving the safety protection and electrical performance requirements, mandating that the door protection device must have fault self-inspection and failure alarm functions. When the device fails, the elevator door system must immediately stop the door closing action and open in reverse; clarifying the insulation performance, withstand voltage performance and electromagnetic compatibility performance indicators of the device to ensure that the device will not produce electromagnetic interference to the elevator control system; fourth, standardizing the environmental adaptability and reliability requirements, formulating the environmental adaptability test standards of the device for the high temperature, high humidity, vibration, dust and strong light interference environment in the elevator car and shaft, stipulating that the device must still meet the standard requirements after 1 million action cycle tests, and the design service life is no less than 10 years; fifth, improving the type test and factory inspection rules, clarifying the mandatory inspection items, test methods and judgment standards of the type test of door protection devices, tightening the sampling rules and qualification judgment criteria of factory inspection, mandating that each device must pass the full project inspection before leaving the factory; sixth, clarifying the installation, commissioning and operation and maintenance specifications, refining the adaptive installation and commissioning requirements of the door protection device and the elevator door machine system, formulating the cycle and project requirements for daily inspection, regular maintenance and function verification of the device, and clarifying the scrapping judgment standard and replacement cycle of the device. The implementation of this standard has comprehensively standardized the production and application market of elevator door protection devices in China, greatly reduced the occurrence probability of elevator door pinching people and objects safety accidents, and also promoted the integration of China's elevator door protection device products with the international market, providing standardized technical support for the global export of China's elevator safety components.
