EN 10210-1 Certification
This standard covers the technical delivery conditions for hot finished structural hollow sections of non-alloy and fine-grain structural steel profiles.
EN 10210-1 Classification
Four grades are specified within the strength classes of non-alloyed steels:
JR, J0, J2 and K2
These grades differ in the specified impact requirements, the deoxidation method, the limitations on the values of various elements (especially those related to sulphur and phosphorus) and the inspection and testing requirements.
According to the classification system in EN 10020, all steel grades in Annex A are non-alloyed quality steels.
Two grades are specified for the strength classes of fine-grained steels:
N and NL.
These grades differ in their carbon, sulphur and phosphorus content and their low-temperature impact properties.
According to the classification system in EN 10020, steel grades S275NH, S275NLH, S355NH and S355NLH are non-alloyed quality steels, while steel grades S420NH, S420NLH, S460NH and S460NLH are alloyed special steels.
EN 10210-1 Short Designation
For the products covered by this European Standard, the steel names are determined according to EN 10027-1; the steel numbers are determined according to EN 10027-2.
The steel designation for non-alloy hollow profile steel consists of:
- The number of this European Standard (EN 10210-1);
- The capital letter “S” for structural steel;
- The expression of the minimum yield strength in MPa for thicknesses ≤16 mm;
- The characters “JR” for quality with specified impact properties at room temperature, “J0” for quality with specified impact properties at 0°C, and “J2” or “K2” for quality with specified impact properties at -20°C;
- The capital letter “H” to specify hollow profiles.
For example; EN 10210-S275J0H
Information to be obtained by the manufacturer
- the quantity
- the type of length, length range or length
- details of the product form:
HFCHS = hot finished circular hollow sections
HFRHS = hot finished square or rectangular hollow sections
HFEHS = hot finished elliptical hollow sections
- the steel designation
- the dimensions
Factory Production Control System
The manufacturer shall establish, document and maintain a Factory Production Control System (FPC system) to ensure that products placed on the market comply with the declared performance characteristics. The FPC system includes written procedures (work instruction), regular inspection and testing and/or audits, and control equipment, supply of feedstock and other input materials, production control and control of finished product results. Records shall be legible, identifiable and correctable.
