Full title and description

St ISO 11901-5:2021 — Tools for pressing — Gas springs — Part 5: Safety instructions for gas springs. This part of ISO 11901 provides safety requirements, installation and operating instructions for nitrogen gas springs used in press tools and stamping dies, with the aim of preventing failures and ensuring safe operation and long service life.

Abstract

Specifies safety requirements and practical instructions for the correct installation, use and maintenance of gas springs in press-tool applications. The document is aligned with other parts of ISO 11901 and includes recommendations (informative Annex A) on operating conditions and handling to maximise lifetime and reduce risk, plus design guidance to ensure safe venting in fault conditions.

Scope

Applies to gas springs intended for use in press tools and die sets. The standard sets out minimum safety requirements, recommended installation and mounting practices, instructions for safe operation, and measures to be taken in the event of component fault (for example controlled venting). It is intended to be used alongside the other parts of the ISO 11901 series covering product characteristics and testing.

Key topics and requirements

• Mandatory safety features for gas springs in press applications, including requirements for venting to atmosphere on fault conditions.
• Installation and mounting instructions to prevent mechanical overloading and improper use.
• Operational limits and recommended operating conditions to maximise lifetime (informative guidance in Annex A).
• Maintenance, inspection and replacement guidance to reduce risk of failure in service.
• Marking, documentation and user information requirements to ensure safe handling and traceability.

Typical use and users

Used by press-tool designers, tool and die manufacturers, maintenance and safety engineers in metalworking and stamping operations, OEMs that integrate gas springs into pressing equipment, and regulatory/safety personnel responsible for machinery safety documentation and operator instructions.

Related standards

Part of the ISO 11901 family (other parts include ISO 11901-1, ISO 11901-3 and ISO 11901-4 that address product characteristics, testing and related requirements). It was developed by ISO/TC 29/SC 8 (Tools for pressing and moulding) and should be applied alongside national machinery safety regulations and relevant ISO machine-safety standards where applicable.
