40、product (extruded rod/bar, tube or profile). If tube, whether seamless or porthole/bridge extruded, 2) reference to EN 573-3 for chemical composition limits, 3) reference to EN 515 for temper designation, 4) purchaser application, in particular whether subsequent anodizing is intended. This shall be

If this is not made clear on the order, the supplier shall a
43、ssume that the specified tolerances for either or both outside and inside diameters are inclusive of ovality. However, if the purchaser specifically requires that the outside and/or inside diameter tolerances are to be both mean and inclusive of ovality, then this shall be clearly stated on the orde
