Proficiency Testing № PTS 21/07

Dear colleagues,

It is our pleasure to invite you to take part in proficiency testing № PTS 21/07

by means of an interlaboratory comparison, including testing and sample taking with subsequent testing.

Subject of testing will be the product “Asphalt mixture” and “Bitumen” under standard methods and parameters, which are given below.

Subject of sample taking will be “Aggregates (fine or all-in material)” according to EN 932-1:1996, item 8.8 with subsequent testing for determination of “loose bulk density” according to EN 1097-3:1998.
