The following are defined:3.1 Normalizing rolling is a rolling process in which the final deformation process is carried outin a certain tempera-ture range leading to a material condition equivalent to that obtained afternormalizing so that th
36、e specified values of the mechanical properties are retained even afternormalizing. The symbol for this delivery condition and for the normalized condition is N.3.2 Additionally to the definitions for thermomechanical treatment and quenching and temperingthe following should be noted:NOTE 1: Thermom
37、echanical rolling (symbol M) may include processes of increasedcooling rates with or without tempering including self-tempering but excluding definitivelydirect quenching and tempering.NOTE 2: Quenching and tempering (symbol QT) also includes direct hardening plustempering.3.3 Purchaser: The person
38、or organization that orders products in accordance with this standard.The purchaser is not necessarily, but may be, a manufacturer of pressure equipment inaccordance with the EU Directive listed in Annex ZA. Where a purchaser has responsibilitiesunder this EU Directive, this standard will provide a
39、presumption of conformity with theessential requirements of the Directive so identified in Annex ZA.4 Dimensions and tolerances on dimensionsThe nominal dimensions and tolerances on dimensions for the products shall be agreed at thetime of enquiry and order with reference to the dimensional standard
40、s listed below.4.1 For non-continuously hot-rolled flat products, refer to EN 10029.Unless otherwise agreed at the time of enquiry and order, class B as specified in EN 10029applies to the tolerance on thickness of plates.4.2 For continuously hot-rolled coil or sheet/plate cut from coils (rolled wid
41、th 600 mm or above)and hot-rolled slit coil in widths less than 600 mm, refer to EN 10051.4.3 For hot-rolled narrow strip (rolled width less than 600 mm) refer to EN 10048.4.4 For stainless cold-rolled sheet/plate, cold-rolled coil and slit coil (rolled width 600 mm orabove) refer to EN 10259 and fo
42、r stainless cold-rolled coil and slit coil in rolled widths less than600 mm refer to EN 10258.Page 8EN 10028-1:2000NOTE: EN 10258 and EN 10259 contain options providing wider dimensional choice.5 Calculation of massA density of 7,85 kg/dm shall be used as the basis for the calculation of the nominal
43、 mass fromthe nominal dimensions of all steels of EN 10028-2 to EN 10028-6. For density of austeniticcorrosion-resisting steels, see annex A of EN 10088-1.
