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 (see www.iso.org/directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

Introduction

This International Standard was developed in response to a worldwide demand for minimum

specifications on UVC safety for products and equipment utilizing UVC lamp fixtures. In this

International Standard, when it comes to personal damage of UV disinfection, the whole UVC band range

is more likely to be included. As for lamps of product equipment, UVC prefers to the 254 nm wavelength.

UVC radiation is a low-penetrating form of UV as compared to UVA or UVB radiation. Measurements

of human tissue show that 4 % to 7 % of UVC radiation, along with a wide range of wavelengths from

[6]

250 nm to 400 nm, is reflected and absorbed in the first 2 µm of the stratum corneum. Hence, the

[7]
amount of UVC transmitted through the epidermis is minimized.

UVC radiation is invisible to humans and exposure to UVC radiation may have an effect on health.

Ocular damage generally begins with photokeratitis but can also result in photokeratoconjunctivitis.

Symptoms, which may not be evident until several hours after exposure, can include an abrupt

sensation comparable to sand in eyes, tearing, and eye pain of various degrees. Such symptoms may

appear within 1 h to 12 h after UVC exposure and resolve fully within 24 h to 48 h. Acute overexposure

to UVC band radiation may cause incapacity due to eye discomfort, but this generally regresses after

several days, leaving no permanent damage.

Cutaneous damage consists of erythema, a reddening of the skin akin to sunburn but without tanning.

The maximum effect of erythema occurs at a wavelength of 297 nm in the UVB band. UVC radiation at

a wavelength of 254 nm is less effective in causing erythema. Therefore, the areas subject to exposure

should be marked. Warning signs should be placed in certain locations to protect personnel or passers-

by from UV hazards. Appropriate locations include access doors, air handling unit outside walls,

equipment room doors, etc.

The International Commission on Illumination (CIE) 2010 completed a review of UVC photocarcinogenesis

risks from germicidal lamps using basic biophysical principles due to the attenuation provided by the

stratum corneum and epithelial t
