本文件规定了气体弹簧的尺寸（单位:毫米）、标称初始力和类型。 本标准适用于弹簧力增大、结构高度相同的7-500-200-000型气体弹簧，并用氮气加压，标称初始力在7-400-N（公差为±5？%）和200-000-N（公差为±5？%）之间，用于冲压工具。 它还规定了标记、技术交付条件和名称。 注？ISO？11901？2中给出了气弹簧安装附件的规格。

This document specifies the dimensions (in millimetres), nominal initial forces and types of gas springs. It is applicable to gas springs with increased spring force and same built height of type 7 500 to 200 000, pressurized with nitrogen with a nominal initial force of between 7 400 N (with a tolerance of ±5 %) and 200 000 N (with a tolerance of ±5 %), for use in press tools. It also specifies marking, technical delivery conditions and designation. NOTE       Specifications of mounting accessories for gas springs are given in ISO 11901？2.
