ISO 11901-1:2003规定了气体弹簧的尺寸（单位:毫米）、标称初始力和类型。 它适用于压力工具中使用的900至100000型气体弹簧，用氮气加压，标称初始力在900 N至100 600 N之间。 ISO 11901-1:2003还规定了标记、技术交付条件和名称。

ISO 11901-1:2003 specifies the dimensions, in millimetres, nominal initial forces and type of gas springs. It applies to gas springs of type 900 to 100 000, pressurized with nitrogen with a nominal initial force of between 900 N and 100 600 N, for use in press tools. ISO 11901-1:2003 also specifies marking, technical delivery conditions and designation.
