Choose the governing route
EN 10305 parts 1–6
The part is not a minor suffix. It determines product route, shape, delivery requirements, and which tolerance and test provisions apply.
On this page
The short answer
Choose Part 1 for seamless cold-drawn circular precision tube, Part 2 for welded cold-drawn circular precision tube, current Part 3 for welded cold-sized tube including the shaped products formerly covered by Part 5, Part 4 for seamless hydraulic/pneumatic tube, and Part 6 for welded cold-drawn hydraulic/pneumatic tube.

This is a selection map, not a substitute for scope clauses in the standards.
| Part | Route / form | Typical decision driver |
|---|---|---|
| EN 10305-1:2016 | Seamless cold drawn, circular | No weld seam; mechanical and precision applications |
| EN 10305-2:2016 | Welded cold drawn, circular | Cold-drawn dimensional and surface refinement with an ERW starting tube |
| EN 10305-3:2023 | Welded cold sized; current scope includes shapes | Cold-sized round, square, rectangular, and related products |
| EN 10305-4:2016 | Seamless cold drawn, hydraulic/pneumatic | Pressure-line service and system-oriented delivery requirements |
| Former EN 10305-5 | Welded cold sized square/rectangular | Legacy designation; scope incorporated into Part 3:2023 |
| EN 10305-6:2016 | Welded cold drawn, hydraulic/pneumatic | Pressure-line service with welded cold-drawn construction |
Handling legacy Part 5 callouts
A drawing citing EN 10305-5 may remain contractually valid under its stated edition. For new work, review EN 10305-3:2023 and document any conversion. Never change the part number on a purchase order without engineering and purchaser approval.
