  • CEN/TS 16637-2 "Construction products - Assessment of release of dangerous substances - Part 2: Horizontal dynamic surface leaching test” is being tested for robustness validation to be upgraded to standard.
  • CEN/TS 16637-3 "Construction products - Assessment of release of dangerous substances - Part 3: Horizontal up-flow percolation test” is being tested for robustness validation to be upgraded to standard.
  • FprCEN/TR 17105 "Construction products: Assessment of release of dangerous substances - Guidance on the use of ecotoxicity tests applied to construction products” is under formal vote.

WG 2 EMISSION TO INDOOR AIR

The situation of the projects is the following:
  • FprEN 16516 "Construction products: Assessment of release of dangerous substances - Determination of emissions into indoor air” will be sent for formal vote and published before the end of the year.
  • The group is developing an amendment to EN 16516 to include the determination of emissions of ammonia from cellulose insulation products at normal conditions (50% RH).
  • The group is developing the Technical Report "Construction products: Assessment of release of dangerous substances - Determination of emissions of ammonia from cellulose insulation products at 90% RH”

WG 3 RADIATION

The situation of the projects is the following:
  • FprCEN/TR 17113 "Construction products - Assessment of release of dangerous substances - Radiation from construction products - Dose assessment of emitted gamma radiation” is under formal vote.
