|Mass||6% in individual lengths|
1)The outside dimensions are measured across the flats at positions at least 50mm from the end of the HSS.
In bare bundle with steel band,or in bulk. Standard lengths are 6, 8 and 12 meter.
Each of the square and rectangular hollow sections shall be marked with the following information.
a)manufacturer's name b)specification designation c)grade letter d)dimension e)heat number
EN 10219 is subject to tensile testing in accordance with EN 10002-1, charpy impact test in accordance with EN 10045-1.
