Light Intensity Measurement: Illuminance Protocol for Commercial Premises, Required Values & Guide

Hello, I need to measure the illuminance in several facilities, specifically these are commercial premises in the gallery, so my question is, where to get the protocol ... in which I will enter the results of the measurement made and what are the required values for this type of room? Could someone possibly send me such protocols? Thank you in advance.

Illumination measurement protocols can be found on the Internet, but they are the same formulas, they may be useful, but first you should read the standard:
PN-EN 12464-1 Light and lighting. Lighting of workplaces. Indoor workplaces.
Where is the list of lighting requirements for specific workplaces. This applies, among others, to the operational illuminance, the glare rating limit or the color rendering index.
Know the scope of the work. Perhaps it is about the operational check of the lighting intensity of common areas in a shopping mall, e.g. sales zone - min. 300 lux.
Not everything can be done with an ordinary luxmeter with a full study of the lighting conditions with artificial light.

But I can't find empty patterns anywhere, maybe someone could provide a link, where to download them? It is probably about the intensity of light at workstations, in small premises, such as a second-hand shop with telephones, a games room, etc.

Why is my colleague not looking at the electrode?

Or in

Thanks for your help, I'm closing.
