Full title and description

STB DIN EN ISO 14118:2018-07 (English) — Safety of machinery — Prevention of unexpected start-up. Provides design-oriented requirements and measures to prevent unexpected or inadvertent starting of machinery so that persons can safely enter or work in hazardous areas. The document is the German adoption of EN ISO 14118:2018 and is identical in technical content to ISO 14118:2017.

Abstract

This standard specifies designed-in means aimed at preventing unexpected machine start‑up to allow safe human interventions in danger zones. It covers prevention of start-up from all types of energy (electrical, hydraulic, pneumatic, stored energy such as gravity or springs, and external influences) and describes constructive and organizational measures to avoid inadvertent starting. The standard does not set performance levels (PL) or safety integrity levels (SIL) for safety‑related parts of control systems; it identifies available means without prescribing solutions for specific machine types.

• Number of pages: 21 (typical national publication length; may vary slightly by national edition/translation).

Scope

Specifies requirements for designed-in means to prevent unexpected start-up of machinery so that safe intervention by personnel in danger zones is possible (see Annex A for guidance). The scope covers unexpected start-up caused by power supplies (electrical, hydraulic, pneumatic), stored energy (gravity, compressed springs), and external influences (wind, etc.). The standard is generic — it does not prescribe detailed measures for specific machines and it does not set PL or SIL values for control system elements.

Key topics and requirements

• Design measures to prevent unexpected start-up (mechanical blocking, isolation, safe positioning, protective devices).
• Identification and control of all energy sources that could cause inadvertent movement (electrical, hydraulic, pneumatic, stored energy, external influences).
• Requirements for safe isolation and reliable lock-out/tag-out type methods during intervention and maintenance.
• Consideration of residual and stored energy and means to dissipate, secure or block it.
• Information and markings to ensure safe working procedures and awareness of unexpected start-up hazards.
• Relation to conformity with the EU Machinery Directive (informative annex mapping essential requirements).

Typical use and users

Used by machine designers and manufacturers (OEMs) to incorporate measures preventing inadvertent start-up during design; by safety engineers and risk assessors when evaluating machine safety and maintenance procedures; by maintenance staff and plant managers to define safe isolation and lock-out procedures; and by conformity assessors and notified bodies verifying compliance with applicable directives and standards.

Related standards

Key related standards include ISO 12100 (general principles for risk assessment and risk reduction), ISO 14119 (interlocking devices associated with guards), ISO 13849-1 and IEC 62061 (safety-related parts of control systems), and EN 1037 (earlier standard on prevention of unexpected start-up). The standard also supports conformity assessment against the essential requirements of the EU Machinery Directive.

FAQ

Q: What is this standard?

A: DIN EN ISO 14118:2018 is the German adoption of EN ISO 14118:2018 (identical to ISO 14118:2017) that specifies measures to prevent unexpected start‑up of machinery so personnel can safely intervene in hazardous areas.

Q: What does it cover?

A: It covers design and organizational measures to prevent inadvertent starting from all energy sources (electrical, hydraulic, pneumatic, stored and external energy). It is generic and does not set performance levels (PL) or safety integrity levels (SIL).

Q: Who typically uses it?

A: Machine designers, OEMs, safety and maintenance engineers, risk assessors, conformity assessors and notified bodies, and plant managers responsible for safe procedures and maintenance.

Q: Is it current or superseded?

A: The 2018 DIN adoption / EN ISO 14118:2018 edition is the current published edition for EN/ISO 14118 (based on ISO 14118:2017). Users should check national standards bodies for any subsequent amendments or newer revisions.

Q: Is it part of a series?

A: It is part of the machinery safety standards family and is commonly used alongside ISO 12100 (risk assessment), ISO 14119 (interlocking devices), ISO 13849 and IEC 62061 (control system safety); it supersedes or replaces older national documents such as EN 1037 where adopted.

Q: What are the key keywords?

A: Prevention of unexpected start‑up; energy isolation; lock‑out/tag‑out; machine safety; stored energy; hazard zones; intervention procedures.
