Testing programme for the PACE-PTS proficiency testing scheme.

During the kick-off workshop the testing programme was discussed and developed among the participants. The decision was made to have a mandatory and an optional testing programme. All laboratories were equipped with a set of standard sand according to EN 196-1 as well as homogenised cement the origin of which was unknown to the laboratories. In addition a set of readily cured mortar prisms produced and cured under identical conditions in the laboratories of BAM. In the proficiency testing scheme on 2014/2015 each laboratory was also equipped with sand and aggregates in order to look at the measurement of the aggregate grading.
