For projects outside of the U.S., demonstrate compliance to testing standard EN 16516:2017 with 2018 updates, be compliant with German AgBB Testing and Evaluation Scheme (2018) thresholds and meet a formaldehyde limit of 10 micrograms per cubic meter after 28 days. For individually tested compounds, sum of R ratios must be less than or equal to 1 for all VOCs with LCI values and summed individual VOC concentrations must be less than 100 ug/m3 for VOCs without LCIs. TVOC value measured after 28 days must be less than or equal to 1000 ug/m3.  

**April 2023 Update:
Laboratories that conduct the tests must be accredited under ISO/IEC 17025 for the test methods they use. Manufacturer statements must include a summary report from the laboratory that is less than three years old.
