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.

Overview

ISO 11901-1:2003 - Tools for pressing - Gas springs - Part 1: General specifications defines the general requirements for gas springs used in press tools. The standard specifies dimensions (mm), nominal initial forces, types, marking, technical delivery conditions and designation for gas springs pressurized with nitrogen. It covers gas-spring types from 900 to 100 000 with nominal initial forces from 900 N ±5% up to 100 600 N ±5%, ensuring interchangeability and safe application in pressing equipment.

Key topics and requirements

Scope and applicability: Gas springs for use in press tools, pressurized with nitrogen, force range 900 N to 100 600 N.

Interchangeability dimensions: Detailed dimensional tables and figures (types 900–100 000) specify stroke lengths, mounting interfaces and tolerances (ISO 2768-m). Dimensions are given in millimetres for consistent manufacturing and replacement.

Maximum filling pressure: Typical maximum filling pressures are specified (e.g., 18 MPa for types 900 and 2 000; 15 MPa for many larger types) and are listed per type.

Pressure filling inlet threads:

Types ≥ 2 500: pipe thread ISO 7 - Rp 1/8 (ISO 7-1)
Types ≤ 2 500: M6 thread
For types 1 500 and 2 500 the inlet may be at the rod end (rod end not spherical).

Marking: Gas springs must be indelibly labelled with at least the manufacturer, gas used, date of manufacture, maximum filling pressure and type.

Technical delivery conditions:

Supplied at nominal pressure at a reference temperature of 20 °C.
Temperature–pressure relation given: p = p0 (1 + 0.0036 · Δt) (to account for pressure changes with temperature).
Rods to be slightly oiled and protected against shocks.

Designation: Clear naming convention. Example:

Gas spring ISO 11901-1 - 1500 ×××× 25 - F (type 1 500, stroke 25 mm, inlet on bottom)

Applications and users

ISO 11901-1 is intended for:

Press-tool designers and manufacturers specifying gas springs for stamping, forming and pressing equipment.

Maintenance and procurement teams requiring standardized, interchangeable gas springs.

Quality, safety and compliance engineers ensuring components meet dimensional, pressure and marking requirements. Typical application: use as nitrogen-pressurized force-generating elements within press-tool assemblies.
