The tests shall be carried out in accordance with either 8.2 (tensile test) or 8.3 (hardness test). Products in stress relieved condition shall conform to the same mechanical property requirements as for non stress relieved material. 6.3 Dimensions and tolerances 6.3.1 General The geometrical properties of the tubes are defined by outside diameter or inside diameter, wall thickness and length. Normally, tolerances for cross-sectional dimensions are applied on the outside diameter (see 6.3.2) and wall thickness (see 6.3.3) but other possibilities may be agreed between the purchaser and the supplier at the time of the enquiry and order [see Clause 5, list entry j)]. Normally, tubes are supplied in lengths with tolerances agreed between the purchaser and the supplier at the time of the enquiry and order [see Clause 5, list entry g)] but tubes may be ordered as "fixed lengths" (see 6.3.4). 6.3.2 Outside or inside diameter The diameter of the tubes shall conform to the tolerances given in Table 16. 6.3.3 Wall thickness The wall thickness, measured at any point, shall conform to the tolerances given in Table 17. 6.3.4 Fixed lengths Tubes in straight lengths ordered as "fixed lengths" shall conform to the tolerances given in Table 18. Tubes in coiled form ordered as "fixed lengths" shall conform to the tolerances given in Table 19. SIST EN 12449:2012
