Cold drawn seamless unalloyed carbon steel (see below) containing a maximum of 0.3 % of carbon
Note : For an unalloyed steel, the maximum content of additives is
1% for manganese and 0.5% for other elements.
In selecting the steel, attention must be paid to obtaining good
elongation properties and adequate weld ability.
The tubing must be bent by a cold working process and the
centreline bend radius must be at least 3 times the tube diameter.
If the tubing is ovalised during bending, the ratio of minor to major
diameter must be 0.9 or greater.
Articles 8.1 to 8.3 inclusive concern rollbars manufactured without
a certificate from an ASN (article 8.4) or from the FIA (article 8.5).
