I had become frustrated with the lack of a database of European testing laboratories so I created my own. I thought I would share some of the laboratories that are currently doing ASTM (or equivalent) testing in Europe:

Centre Scientifique et Technique du Bâtiment (CSTB), FRANCE
University of Athens, GREECE
ENEA, Italy
Università di Modena e Reggio Emilia, ITALY
Uppsala University The Ångström Laboratory, SWEDEN
SPF-HSR, SWITZERLAND
TNO Construction and Environment, NETHERLANDS
--
Through this research I have found that most of these laboratories use European standards for emissivity and reflectance measurements for example:

CIE 130-1998 Practical Methods for Measurement of Reflectance and Transmittance
OR
ISO 9845-1. (Solar energy -- Reference solar spectral irradiance at the ground at different receiving conditions--Part 1:Direct normal and hemispherical solar irradiance for air mass 1,5

I would be interested if other projects in Europe have used other standards as equivalency for ASTM standards. Or if you could list other testing laboratories that would be greatly appreciated.
