近年来国内燃料电池电动汽车产业迅速发展,燃料电池发动机作为燃料电池汽车的动力核心,其关键部件研发及系统集成技术随之不断更新,原有燃料电池发动机测试评价相关标准亟需升级完善。因此,为适应新的技术现状,我国于2022年12月发布了GB/T 24554-2022《燃料电池发动机性能试验方法》标准。老版GB/T 24554-2009《燃料电池发动机性能试验方法》已实施十余年,此次GB/T 24554-2022的发布实施,对于完善燃料电池发动机测试评价方法,促进燃料电池产业可持续健康发展具有重要意义。本文主要阐述GB/T 24554-2022中主要技术内容及其与2009版标准的异同。 相似文献

国家标准是一国标准体系的基础和主体、国内贸易和国际贸易的基石、推动国内国际贸易双循环的重要技术支撑。完善国家标准体系对培育强大国内市场和建设贸易强国具有重要意义。国家标准通过竞争力效应、信息效应和共同语言效应,以提升产品质量、促进转型升级和引领创新驱动促进国内贸易,以便利经贸往来、促进技术交流和支撑产能合作促进国际贸易。中国国家标准具有规模优势和结构优势,应保障不同类别国家标准有效供给规模,提高国家标准国际化水平并开展国家标准实施效果评价,完善国家标准体系促进国内国际贸易双循环。 相似文献

Standardization receives varied attention in different countries. Based on the Chinese national standardization status, this paper sets an evaluation system of national standardization on the principles of logic, comprehensiveness and operability, taking into account national standards and standardization activities. The evaluation system evaluates the national standardization development level through four aspects: standard development,standards implementation, standardization supporting measures, and participation in international standardization. This evaluation system provides a reasonable basis to evaluate the national standardization development level. The survey shows that if China wants to enhance its standardization development level, China needs to improve its standard development level, strengthen implication and application of standards, expand the standardization support measures and continuously improve the level of participation in international standardization. 相似文献

The system for Metrology in Chemistry in Germany is described. At the national standards level, a network of high-level chemistry
institutes coordinated by the national metrology institute, PTB, provides the primary references for chemical measurements.
A dissemination mechanism employs chemical calibration laboratories accredited within the framework of the German Calibration
Service (DKD). They act as “multipliers” between the national standards level and the user level by providing the user with
calibration means which are traceable to the SI via national standards. Traceability structures in clinical chemistry, electrochemistry,
elemental analysis and gas analysis are described 相似文献
