6. Mandate M/366
Purpose: Harmonisation of existing national regulations.
Emissions of regulated dangerous substances.

7. Mandate M/366
Emissions under normal conditions of use.
Existing standards shall be used wherever possible.

8. Mandate M/366
„Horizontal“ standard
Applicable to all construction products covered by the mandate.

9. Mandate M/366
Validation is mandatory
No publication of the standard without complete validation.

14. Small changes, large effects
Basis of the work: ISO 16000
ISO Emission test chamber method
ISO Sampling, GC/MS
ISO Formaldehyde and other carbonyl compounds
EN Emission test chamber Formaldehyde
 needed because of existing regulations

15. Small changes, large effects
Reasons for deviation from ISO 16000
Reduced margin for different handling
Improved reproducibility and comparability
Improved resolution and quantification of substances
Adaptation to the technical progress

16. Small changes, large effects
Examples for changes: Loading factors
ISO
No fixed values
First draft
Wall and ceiling
Floor
Sealants
Latest draft
Small surfaces
Calculated emissions for products like radiators, doors, windows and their coatings lowered by factor 8

17. Small changes, large effects
Examples for changes: Definition of TVOC
Total area under chromatogram as Toluene equivalent
Sum of individually quantified substances
Up to 4 h of calibration for each analysis  up to 800 € higher costs for chamber test

18. First draft 50% rH +/- 3% EN 717-1 45 % rH ISO 16000-9 50% rH +/- 5%
Small changes, large effects

2010
Validation step 1 „robustness“
public
Technical Specification - TS
June 2013
Validation step 2 „round robin“
public
EN standard
Not before 2014

26. Validation step 1 „robustness“
Validation project
Validation step 1 „robustness“
Variation of parameters  effects?
Investigation of open questions and disagreed details
Scientific work, funded by European Commission
Call for tenders  several work packages

27. Validation step 2 „round robin“
Validation project
Validation step 2 „round robin“
Interlaboratory comparison
Investigation of reproducibility and comparability
Important for accreditation of laboratories
Financial aspects still open ?
