Overview - ISO 4007 / EN ISO 4007:2018 (EN ISO 4007:2018)

ISO 4007:2018 (adopted as EN ISO 4007:2018 / EN ISO 4007:2018) is an international vocabulary standard for personal protective equipment (PPE) - eye and face protection. Its scope is limited to defining and explaining the principal terms used in the field of eye and face protection, providing a common language for designers, manufacturers, test laboratories, regulators and safety professionals.

Key facts:

• Third edition (2018), supersedes ISO 4007:2012.
• Focus: terminology and definitions, not performance requirements.
• No normative references; intended as a reference glossary for related PPE standards.

Key topics covered

The standard organizes and defines terms across technical domains relevant to eye and face protection, including:

• Risks and hazards: concepts such as risk, hazard, harm, blue‑light hazard, ultraviolet hazard, retinal thermal hazard.
• Optical radiation: definitions of radiation bands and related vocabulary.
• Sources of non‑ionizing radiation and radiometry/photometry terminology.
• General terms for types and components of eye and face protectors, geometrical properties, and non‑lens parts.
• Special protector types: welding protectors, mesh protectors, secondary lenses and protection from short‑circuit electric arc.
• Optical materials and properties: lens materials, transmittance, reflection, polarization, welding filters.
• Wearer characteristics, test equipment, and a glossary of abbreviations and symbols.
• Informative Annex A on spectral weighting functions and spectral distributions.

Notable editorial updates in this edition:

• The term “ocular” replaced by “lens”.
• Addition of 52 new terms and revision of over 100 definitions.
• Clarified wavelength limits (e.g., UV‑A upper limit may be 380 nm or 400 nm depending on application).

Practical applications - who uses ISO 4007

ISO 4007 is a reference tool that supports consistency and clarity across the PPE ecosystem:

• Manufacturers and designers use the vocabulary when specifying product components and documentation.
• Test laboratories and conformity assessment bodies apply shared definitions in test reports and standards cross‑references.
• Standards committees and technical writers rely on ISO 4007 to harmonize terminology across related standards.
• Procurement officers, safety managers and regulators use consistent terms in specifications, regulations, training and incident reports.

Related standards and references

• Prepared by ISO/TC 94 (Personal safety) in collaboration with CEN/TC 85 (Eye protective equipment).
• References ISO/IEC Guide 51:2014 for safety terminology; users should consult product and performance standards for technical requirements.
