Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2. www.iso.org/directives

INTERNATIONAL STANDARD ISO 12609-1:2013(E)
Eyewear for protection against intense light sources
used on humans and animals for cosmetic and medical
applications —
Part 1:
Specification for products
1 Scope
This part of ISO 12609 specifies performance and labelling of eye protectors used for ILS equipment
used on humans and animals for cosmetic and medical applications against excessive exposure to optical
radiation in the spectral range 250 nm to 3 000 nm, with the exception of laser radiation.
This part of ISO 12609 provides a specification for an eye protector expected to cope with the majority
of applications. A more rigorous procedure for determining appropriate eye protection against spectral
outputs from ILS equipment is described in the annexes.
This part of ISO 12609 is not applicable to eye protectors for use with tanning equipment, ophthalmic
instruments or other medical/cosmetic devices, the safety issues of which are addressed through other
European and International standards.

indispensable for its application. For dated references, only the edition cited applies. For undated
references, the latest edition of the referenced document (including any amendments) applies

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
blue light hazard
potential for a photochemically induced retinal injury resulting from optical radiation exposure in the
wavelength range 300 nm to 700 nm
3.2
filter protection factor
FPF
factor by which the filter attenuates the weighted ocular exposure
Note 1 to entry: Mathematical expressions for FPF are given in Annex A and example calculations in Annex B
and Annex C.
3.3
infra-red lens hazard
potential for a thermal injury to cornea and lens of the eye resulting from optical radiation exposure in
the wavelength range 780 nm to 3 000 nm
3.4
intense light source
ILS
device incorporating one or more non-laser sources of optical radiation of the wavelength range 250 nm
to 3 000 nm and intended for creating biological effects in humans and animals
Note 1 to entry: It can operate in a continuous or pulsed regime.
3.5
retinal thermal hazard
potential for a thermal retinal injury resulting from optical radiation exposure in the wavelength range
380 nm to 1 400 nm
3.6
ultraviolet hazard
potential for skin and ocular acute and chronic adverse effects resulting from optical radiation exposure
in the wavelength range 250 nm to 400 nm
4 Transmittance
4.1 General
The spectral transmittance of the ILS eye protector at the wavelengths between 250 nm and 3 000 nm
shall be specified.
The spectral transmittance τ(λ) of the eye protector material shall be determined for normal incidence.
The wavelength shall be determined at not more than 10 nm intervals with the central wavelength
known to within ± 2 nm from 250 to 800 nm and within ± 4 nm above 800 nm. The bandwidth of the
detector (full width half maximum) shall not exceed 5 nm.
Filters with angular dependent transmittance shall be measured at angles of incidence between at
least 0° and 30°.
In addition, ILS eyewear may be designated F- or B- scale numbers according to 4.2 and/or 4.3.
4.2 F-classification
ILS eyewear may be designated F-scale number using the F-classification scheme described in Table 1.
NOTE The F-numbers in Table 1 are related to the shade numbers with some relaxation in the infrared region.
Luminous transmittance shall be determined according to 4.4.
