For research, development and quality certification purposes, some simply formulated 1- and 2-part
"reference test adhesives" have been developed and, from the most important and most often applied, some
materials have been selected as "reference test materials". This technical report offers for each of these
reference test adhesives and reference test materials some information and specify some properties. CEN/TC
193/WG 5 takes care for a continuous updating of these data sheets.
