JTC 09 (D1/D2/D3/D6): CIE System for Metrology of ipRGC Influenced Light Response
This International Standard will define spectral sensitivity functions, quantities and metrics to describe radiation for its ability to stimulate each of the five photoreceptor types that can contribute, via the melanopsin-containing intrinsically-photosensitive retinal ganglion cells (ipRGCs), to retina-mediated non-visual effects of light in humans.
This International Standard will be applicable to visible optical radiation in the wavelength range from 380 nm to 780 nm. In addition, this Standard will include information concerning the effects of age and field of view (FOV) when quantifying retinal photoreceptor stimulation for ipRGC-influenced light (IIL) responses.
This International Standard will not give information for particular lighting applications, or for the quantitative prediction of IIL responses.
This International Standard will not address health or safety issues such as those resulting from flicker or photobiological safety and will only relate to retinal photoreception.

JTC 10 (D8/D1): A New Colour Appearance Model for Colour Management Systems: CIECAM16
To recommend a new colour appearance model, CIECAM16, to replace the CIECAM02 model for colour management systems.

JTC 11 (CIE-ISO): Light and Lighting – Maintenance Factor – Way of Working
This deliverable will provide a standardized way of working for determining the maintenance factor for both indoor and outdoor installations using the methodology as described in CIE 154:2003 & CIE 97:2005.
The deliverable will combine insights from IEC standards w.r.t. product performance of luminaires and light sources currently in the market with the existing determination methodology from CIE technical reports. Furthermore, it will reference to the data in the CIE technical reports w.r.t. the impact of the environment on luminaires (accumulation of dirt on surfaces and luminaires).

JTC 12 (D1/D2/D8): The Measurement of Sparkle and Graininess
To provide a methodology to measure sparkle and graininess, and to develop a measurement scale. Measurands will be defined and the requirements for their measurements will be well normalized, in such a way that different instruments can provide the same spectrophotometric data from the same specimen. A psychophysical method will be recommended to obtain visual data, and its correlation with the spectrophotometric data will be worked out to develop the measurement scale for sparkle and graininess.
