RDS (Regulated Dangerous Substances)

Page to be Updated…

This legislation is under European Commission (EC) Mandate 366 and most of the work is in sub committees of CEN TC 351.

The release of Regulated Dangerous Substances (RDS) would, for admixtures, only apply to release from hardened concrete in the form of a monolith. EFCA is therefore working with the concrete industry on this legislation through TC 104/WG 14.

WG 14 believes that Concrete poses no risk with respect to release of RDS (note that concrete is frequently used to contain and neutralise RDS). This group is therefore most active on the Without Testing (WT) sub group of TC 351 and is fully involved in drafting the report. EFCA members are also involved in TC 351 through CEPMC and also their national mirror groups.
