Indoor air limit values (LCI, NIK, CLI, CREL, ...)
LCI, CLI, NIK, and CREL values are used by several emission rating schemes as limit values for evaluating emissions of VOC into indoor air (or COV in French).
Here you can see a comparison of limit values for emission into indoor air.
The sources are:
German LCI / NIK values -

- in English: www.umweltbundesamt.de/building-products/agbb.htm
French AFSSET (now: ANSES) - CLI values:

Californian CREL values, used for Section 01350, BIFMA, Floor Score, CRI GLP, Indoor Advantage Gold, CHPS, and more programmes: www.oehha.org/air/allrels.html. Please note: These programmes require 1/2 CREL shall not be exceeded for any substance, with the exception of formaldehyde and acetaldehyde.
LCI, CLI, NIK, and CREL values will determine partly future product development and technical trends for a number of interior finishing products with emissions of VOC into indoor air.
There is an on-going initiative to harmonize LCI values throughout Europe. Latest progress can be seen on the website of that project.
