Scope

Main technical content: I. This standard is primarily based on the industry standard QB/T 2697-2013 *Ground Spring*, while incorporating the technical requirements of advanced products from outstanding domestic and international manufacturers. The standard features a reasonable structure, accurate descriptions, and clear hierarchies. The referenced standards are currently valid and comply with the provisions of GB/T 1.1-2020. II. The standard was developed in accordance with the positioning and requirements of group standards. During the drafting process, we extensively solicited and incorporated opinions and suggestions from all parties, while taking into account the current status and development direction of the hydraulic ground spring industry, ensuring strong practicality. All technical indicators and requirements in the standard are verifiable and testable, with the test methods supported by relevant standards and capable of being translated into certification implementation guidelines. III. The standard defines terms and definitions, technical requirements, test methods, inspection rules, marking, installation instructions, packaging, transportation, and storage for hydraulic ground springs. The main technical indicators meet both domestic first-class and international advanced standards, fulfilling the basic requirements of group standards. Compared with QB/T 2697-2013 *Ground Spring*, the main advances include: 1) Improved product leakage indicators, ensuring no leakage during the entire performance test process; 2) Enhanced the maximum opening angle of the product, expanding its application fields; 3) Significantly enhanced the impact of temperature on closing time, with a minimum temperature of -40°C, further expanding the product's application range and highlighting its unique features; 4) Increased the corrosion resistance of the product from 80% to 90%, better aligning with the high-quality characteristics of current products.
