Emergency Lighting in Road Tunnels

CIE 193:2010 ISBN 978 3 901906 91 6

This report makes recommendations for emergency lighting in road tunnels longer than 500 m, to facilitate the safe evacuation of vehicle occupants in emergency situations such as fire. The recommendations may also be valid for tunnels less than 500 m in length, where conditions such as high traffic volume, or severe curvature or gradient apply. It The report addresses the fundamental issues of emergency lighting for evacuation routes, emergency exits, escape routes and lay-bys, as well as giving some practical advice regarding aspects of installation and maintenance in road tunnels. It recommends lighting levels and general provisions for emergency lighting installations that, based on experience, are considered to be necessary for the safety of people driving through road tunnels in case of an incident and particularly of fire. However, as there are different types of road tunnels, both in construction and traffic conditions and various types of incidents may occur, this report should be considered as a list of minimum recommendations for emergency lighting in tunnels, to be completed by means of specific risk analysis for the particular tunnel.

This report is intended to be used in conjunction with CIE 88 (2nd revision – 2004 or any further revision) or with elevant Regional or National standards, directives and regulations for road tunnel lighting. The latter may include requirements that differ from the recommendations of this report, and take priority over them. Before following the recommendations of the report in a particular location, the existence of any relevant legal requirements should be investigated.

The publication is written in English, with a short summary in French and German. It consists of 14 pages with 7 figures and is readily available at the National Committees of the CIE or via the website of the Central Bureau of the CIE (www.cie.co.at).

The price of this publication is EUR 66,--

Practical Daylight Sources for Colorimetry

CIE 192:2010 ISBN 978 3 901906 90 9

This publication discusses the state-of-the-art of practical daylight sources for colorimetry. It provides information on these lamps and devices used for illumination in the visual evaluation and instrumental measurement of non-fluorescent and fluorescent specimens.

Suppliers of lamps, booths and spectrophotometers provided some of the data on daylight sources. TC members and advisors at four institutions measured the rest. These institutions are the University of Derby (UK), the Hong Kong Polytechnic University (Hong Kong, China), the University of Pannonia (Veszprém, Hungary) and SENAI/CETIQT (Rio de Janeiro, Brazil).

The report concludes from these data that practical daylight sources are commercially available that satisfy the criteria of the relevant national and international standards for both visual evaluation and instrumental measurement. Filtered tungsten, filtered xenon and fluorescent lamps currently provide the best results for visual evaluation. Pulsed filtered xenon provides the best results for instrumental measurements. Light-emitting diode (LED) sources may appear as viable alternatives for both applications in the not too distant future.

Standardization of any particular source as "best representing daylight" is not recommended. There are significant differences between the spectral properties of the sources currently used in visual evaluation and the sources used in instrumental measurement. These differences produce large differences in the rendering of
colours of specimens, especially fluorescent specimens.

The publication is written in English, with a short summary in French and German. It consists of 39 pages with 14 figures and 10 tables, and is readily available at the National Committees of the CIE or via the website of the Central Bureau of the CIE (www.cie.co.at).

The price of this publication is EUR 108,--
