EN 10210-1 and EN 10210-2 specify the technical delivery conditions, tolerances, dimensions and cross-sectional properties of thermoformed hollow profiles of round, square, rectangular or oval shape and apply to thermoformed hollow profiles whether or not they have been subsequently Heat treatment, or cold forming and subsequent heat treatment to obtain the same metallurgical conditions as the thermoformed product.
Manufacturing: Pipes complying with EN 10210-1 and EN 10210-2 shall be manufactured by hot or cold working.
Delivery status: Pipes should be delivered in two statuses, A quality JR, J0, J2 and K2 - hot processing, B quality N and NL - normalizing, including normalizing rolling.
Inspection and testing: chemical composition analysis, tensile test, J2, K2 level impact test, non-destructive testing of welded pipe welds, surface inspection, dimensional inspection.
The EN 10210 standard has 3 parts, they are:
EN 10210 Part 1: Technical delivery conditions
EN 10210 Part 2: Tolerances, dimensions and section properties
EN 10201 Part 3: Technical delivery conditions for high-strength weathering steels
