Scope: 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 compact built height of type 1700 to 200000, pressurized with nitrogen with a nominal initial force of between 1700 N (with a tolerance of ±5 %) and 200000 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.
