Sure, but that is a "process spec" (that the marketing people have managed to transmit as representing "better quality" whilst in reality, and at the most it represents "same quality").
I was talking more about "product specs" and "tests" performed on goods/materials.
If I tell you that reaction to fire of a product is:
Class B-s1, d0
(UNI EN 13501-1; EN 13823; EN ISO 11925-2)
you have no way to understand (nor does usually the technician that may be assisting you) what (the heck) it means.
You will find tables giving you the corresponding classification in your country (so yes, the government is involved as well), usually different from the ISO standard and you will know that B means "not likely" inflammable, the s1 means that it emits "a little" smoke when in fire and d0 means that combustion will not produce burning drops of material, but you don't know in which conditions the tests have been made.

When you check (indirectly, like from here):
http://fr.polymerinsights.com/testing/flammability/en-iso-11...
how the tests are performed, instantly, and no matter what ISO, your government or any local Law says, you will want to have A1 materials (non-combustible) only in your home.
The test that classified the material as "B-s1, d0" (among the best classifications after the A1 or non-combustible) equates more or less to say that your toddler with a cigarette lighter did not manage to put your house on fire in 30 seconds (but it says nothing about a larger flame or a more extended time).
