EN 50005 relay contact naming convention -- previously head EN 50011 aka BS 5583

Hi

I looked at 11 pin relays recently and for the first time noticed the pin numbering scheme. See attached picture for this example,
For example, for the same contact (i.e. same sequence number = 1) the pins are 11 for common 12 (NC) 14 (NO) If this single pole double throw was implemented with 2 switches (double pole single throw) the terminals would have been 11 & 12 for (NC) and 23 & 24 for (NO)

I was surprised I never really noticed this. It lead me to this standard.
http://webshop.ds.dk/Files/Files/Products/22195_attachPV.pdf  only first page shown
https://www.scribd.com/document/282455490/Document   this shows the standard is only 12 pages long.

Has anyone seen this entire standard and can you recall if there are more things to be known from this standard?
40 Euro for the standard is a bit much

Maybe there is a good app note that you can point me to that discusses all/most of the things defined in this standard.

ADITION TO ORIGINAL POST.
I have attached a picture from another OMRON datasheet showing the pin numbering for a contactor. The picture is dpst.png.
This might explain the numbering system for the example above where the SPDT is separated out into DPST.

It can be seen that the numbers for the contacts of the first switch start with 1 and the contacts numbers for the second switch start with 2. If a contact is NC the second digits in the contact numbers are 1 and 2 and if the contact is NO the second digits are 3 and 4.

See more info in section "Terminal marking" on page two in the attached pdf (Finder-general-technical-information-en.pdf)

This section elaborates on the standards for terminal marking.

It's clear that this standard (or set of standards, see below) is applicable to more than just relays and contactors. It is also applicable to the terminal numbering of timers, special function relays, and more. See the rest of the pdf.

The pdf (441442.pdf) shows the correct applicable European standards. Would have loved to see these standards but I can't even find them on the https://www.cenelec.eu/ website.
So if it's difficult to buy them I suppose few people have peeked inside.
