Here is a question about this article: One significant part of treaty making is that signing a treaty implies recognition that the other side is a sovereign state and that the agreement being considered is enforceable under international law.

What is the answer to this question: Under what do all parties to a treaty recognize the provisions of the treaty are enforceable?

So... international law

Here is a question about this article: The vast majority of devices containing LEDs are "safe under all conditions of normal use", and so are classified as "Class 1 LED product"/"LED Klasse 1". At present, only a few LEDsextremely bright LEDs that also have a tightly focused viewing angle of 8 or lesscould, in theory, cause temporary blindness, and so are classified as "Class 2". The opinion of the French Agency for Food, Environmental and Occupational Health & Safety (ANSES) of 2010, on the health issues concerning LEDs, suggested banning public use of lamps which were in the moderate Risk Group 2, especially those with a high blue component in places frequented by children. In general, laser safety regulationsand the "Class 1", "Class 2", etc. systemalso apply to LEDs.
What is the answer to this question: How are most LEDs classified?
****
So... Class 1 LED product
