The primary designation is DIN 912. The individual product sheet also lists catalogue references ISO 4762, BS 4168-1, ASME B18.3.1M, NEN 1241 and NF E25-125. Listing these references does not declare that all the standards are fully identical.
The catalogue specifies a full thread for L ≤ 40 mm. The variant with a length of 40 mm meets this condition. The catalogue value b = 32 mm is a series parameter and has not been assigned as the thread length of this variant.
