Rickard Lindström (project lead for the Swedish tank trials) states that while the armour given to Sweden was the export version, the firing trials were conducted against “the best available” armour.
Yes it was the best export armour GDLS had at the time i.e. it was meant to be better armour then the original FMS armour package, however it was not equivalent to the US’s DU armour as GDLS did not have a DU armour equivalent until after the Swedish trials, i.e. what was used in Greece and Turkey was comparable to the US’s M1A2 DU armour and it was called the Improved FMS armour package:

FYI that “news article” was directly quoting the vice president of international business of GDLS i.e. Peter Mcvey:
Also in regards to what Lindstrom said about DU, that was not in regards to the US’s DU armour, that was in regards to them testing DU in general as potential armour, however as I have already stated above, the Swedes wanted the US’s DU armour.
Everything indicates that the armour protection offered by DU M1A2 is the same or equivalent as that found on the proposed non-DU M1A2 (the weight of the tested M1A2 was 62.5t while quite a few sources put the weight of the DU M1A2 at 61.4t).
Except it does not, as stated above, a non-DU armour package that was comparable to the US’s DU armour didn’t exist in 1993. The weights are also irrelevant, 62.5 tons is most likely the full combat weight, either that or that was the weight with the Swedish add on armour, because not even the Australian M1A1 AIM weighs 62.5 tons, and the Australian AIM received the Advanced Non-DU armour:

So, all up there are 4 known FMS armour packages, the original FMS armour, the Swedish one, the Improved FMS (HAP-1/HAP-2 equiv.) and the Advanced FMS non-DU armour (HAP-3 equiv.).
They were even contemplating sending DU armour to Greece.
I think the “armour issues” slide says enough.
Yes when all sources are given, they point to the fact that what was tested in Sweden was not comparable to the US’s DU armour.
