Hello there!

I am looking for some help and I hope that I will find here someone who will make me stop crying for it.
I am writing an elaboration about european emission standars, and I found two things that are not clear for me.
Firstly, I'd like to know, what deterioration factors really are? Are they admissible aberrations to existing limits? For example - if the limit for CO is 2,72 g/km, then it really could be (with deterioration factor 1,4; adding) 4,2? Or it is percentile value, which is more probable (only 0,03 g/km of difference)? If both things written here are wrong, how could You austerely define it for me?

Secondly - Confirmation of Production. This phrase appears with EURO 1 emission standard. These are additional values (placed in brackets in the table), higher than standard, defined by European Comission. I have no idea what are they, and I cant find any information about it. Truelly, I more or less know what they are used for (quoting): "means of evidencing the ability to produce a series of products that exactly match the specification, performance and marking requirements outlined in the type approval documentation."
The question is: how do they regard to EURO emission standards, wchich ARE exactly "means of evidencing the ability to produce a series of products that exactly match the specification, performance and marking requirements outlined in the type approval documentation." What is the difference between this two things?

I would be very thankful, if somebody will help me. Cheers!

P.S. Sorry for my english. As You can see I am from Poland and I appreciate that there could be many mistakes in my post.
