Options see 4. The CEV shall not exceed the maximum values given in tables 31 to 34, as appropriate to the product. In all cases the specified properties shall be obtained see 6. The ladle analysis shall include details of all the elements in the CEV formula. The analysis shall be carried out on the basis of one test per cast. The downloadr shall indicate which elements are required see 7.

This option is not applicable to material supplied in bundles. For grades 40 and 43 the colour shall be red. For grades 50 the colour shall be blue. For grades 55 the colour shall be green. For grades WR the colour shall be white.
See clause Thickness tolerances for plates: Thickness tolerancesfor plates: Deviations shallbe measured a t a point a minimum of 20 mm from the longitudinal edges and a minimum of 50 mm for the transverse edge. When distances betweenpoints of contact are between mm and mm, the deviation shall be obtained by takingthe distance betweenpoints ofcontact and calculating proportionally from the deviation given for a mm straightedgein table Euronorm Class 1 Wide flats shall be supplied to the thickness tolerances given in table 39 see Specialflatnesstolerances forplates Ordered thickness length selected Permitted deviations for ordered widths in mm Less than to less than to less than to less than less than to to to less than less than to 3 to less than 4 mm 1 O00 mm 4 to less than 6 3 8 3 7 3 7 mm 4 mm mm 11 4 5 15 4 - mm - - mm mm - 5 I14 l I - 4 16 4 1 O00 11 1 4 15 5 18 6 t o less than 8 1 O00 1 O00 1I 4 11 I 9 4 l 8 to less than 10 10 t o less than 20 1 O00 1 O00 I 10 4 12 20 up to and including I 3 7 4 8 Table Thickness tolerances for wide flats: Euronorm Class I Ordered thickness Tolerances: Thickness tolerancesfor wide flats: Thickness tolerances for flats: The edge camber tolerances shall be 0.
The deviation in flatness in the transverse direction shall not exceed 0. The maximum deviation in flatness in the longitudinal direction referred to a straightedge length of mm shall not exceed 3 mm.
In the case of a shorter measuring length of mm upto but not including mm, the maximum deviation shall not exceed 0. Size tolerances for round and square bars: At the time of enquiry and order the downloadr shall specify: The suffix z followed bY Ist25 Or 35, as appropriate, shall be added to the steel designation see note to section three.
C , bend t e s t s shall be carried out in accordance with appendix G andshall comply with the requirements given in table 50 see clause In this case the downloadr accept the shall material from which the test samples have been cut provided always that the test resultscomply with this standard.

Indicative Charpy V-notch impact values at temperatures otherthan those given in tables 13,15 and 19 Tables 46,47 and 48 give values of Charpy V-notch impact values a t temperatures other than those given in tables 13, 15 and These values are indicative only and are not subject to verification by test. Indicative Charpy V-notch impact values: Bend test for plates, strip and flats in thicknesses up and wide to including 25 mm G.
Bend test requirements for plates, strip and wide flats in thicknesses up to and including 25 mm Figure in parentheses refers t o the note following this table, G. G rade Bend max.
For smaller sizes, the maximum width obtainable shall be used. The bending shall be carried out in accordance with BS The bend diameters given table 49 are for specially in prepared t e s t pieces see G. In general, plates, strip and wide flats in thicknesses up to 25 mm 0 can be formed to 9 ' without heating providedthe following precautions are taken.
Knife edges should be avoided. In particular, heavy shearing burr should not be present. Burr produced by shearing or blanking should be on the inside of the bend. For guidance table 50 lists the recommended minimum internal forming diameters for typical cold forming practice. The number for telephone enquiriesis and for telex Petroconsultants, Inc.
