How these numbers are measured

Luminance (cd/m², i.e. nit) — measurement method for transmissive LCD modules is defined in IEC 61747-30-1.
Operating temperature range — the ambient band a module is rated to run in. Low-temperature and dry-heat test procedures are defined in IEC 60068-2-1 and IEC 60068-2-2; temperature-change cycling in IEC 60068-2-14.
Backlight lifetime — expressed as LED lumen maintenance; measurement method per IES LM-80 (minimum 6000 h), with long-term projection per IES TM-21.

These are generic test-method standards cited to explain how each specification is defined and measured. They are not product certifications. The actual test conditions and rated values for each RONEN model are stated in that model's datasheet.
