DIN 3852-2 and ISO 1179-1 standards has the same points as follows:
For Stud ends and ports of fittings, valves and plug screws
BSPP parallel thread port
The difference is between DIN 3852-2 and ISO 1179-1as follows:
ISO 1179-1: Connections for general use and fluid power — Ports and stud ends with
ISO 228-1 threads with elastomeric or metal-to-metal sealing.
DIN 3852-2 standard specifies the dimensions, types and designation of stud ends for fittings, valves and plug screws (port plugs) and their ports that are not specified in DIN EN ISO 1179-1 to DIN EN ISO 1179-4.
DIN 3852-2 contains specifications for component parts with
Whitworth pipe threads as in DIN 3858.

Here is pictures of 24degree cone fitting ends to BSPP stud end fitting, with type E sealing of DIN 3852-11, tube end connection will need compression nut, cutting ring to connect hydraulic tubes.
This picture shows din 3852 system fittings used in heavy duty equipment such as excavator, from hydraulic manifolds ( bspp port dimensions ) flowing in or out, need BSPP stud end fittings( form a,b,e types of DIN 3852-2 bspp fittings), metric compression fitting end to types of hydraulic tube with cutting ring connection, hose assemblie connection, swivel adapter connections.
Types of Tube end connection to DIN 3852 part 2 stud fittings as follow:
From O-ring face seal fittings
Explains the manufacturing process: 1. DIN 3853-2 G thread adaptors, with Type E DIN 3852-11 sealing groove; 2. inspction by equipment; 3. electroplating; 4. assemblied the correct ED seal. 6, show CNC automatic workshop.
The related BSPP thread port with O-ring seal standards is DIN 3852-21.
