Overview
EN ISO 11553-1:2020/A11:2020 is a CEN amendment to EN ISO 11553-1:2020 - Safety of machinery - Laser processing machines - Part 1: Laser safety requirements (ISO 11553-1:2020). The A11 amendment (approved 14 October 2020) revises the informative Annex ZA that maps the standard to the essential requirements of the EU Machinery Directive (2006/42/EC). When cited in the Official Journal of the European Union (OJEU), the normative clauses of this standard provide a presumption of conformity with the corresponding Directive requirements for laser processing machines.
Key topics and requirements
This standard and its A11 amendment focus on laser machine safety and the interface between technical requirements and regulatory conformity. Main topics include:
- Laser hazard considerations for laser processing machines (optical and non-optical hazards) and required design measures.
- Safety-related design and construction practices for machinery to reduce laser radiation risks during manufacture, setup, operation, maintenance and servicing.
- Control measures and protective devices, such as interlocks, guarding, emergency stops and administrative controls-aimed at preventing or reducing exposure to hazardous radiation.
- Information for use and safety documentation, including labeling, warnings and operator instructions that are necessary to maintain safe operation.
- Relationship to Machinery Directive: Annex ZA in A11 provides a clause-by-clause correspondence (notably clauses 5–8 and clause 7 related to laser radiation) to Annex I of Directive 2006/42/EC to support conformity assessment.
- Scope and applicability for laser processing machinery (ICS: 13.110 Safety of machinery; 31.260 Optoelectronics/laser equipment).

Practical applications and users
EN ISO 11553-1:2020/A11 is intended for:
- Manufacturers and system integrators of laser cutting, welding, marking and similar laser processing machines to design compliant equipment.
- Safety and compliance engineers preparing risk assessments, technical documentation and CE marking evidence.
- Notified bodies and conformity assessors using the Annex ZA mapping when evaluating machines against the Machinery Directive.
- Maintenance teams and end-users seeking manufacturer guidance and safety instructions to operate and service laser machinery safely.
- Regulators and standards committees aligning national standards and procurement specifications.
Related standards
- ISO/EN standards on laser safety and machine safety generally interface with EN ISO 11553-1; consult the Machinery Directive and other sector-specific standards for full compliance context.
