1 Scope 1.1 This standard specifies the manufacturing, inspection and acceptance requirements of aluminium, titanium, copper, nickel and nickel alloy pressure vessels, and common modes and basic parameters of heads. 1.2 This standard is applicable to semispherical, elliptical, dished, spherical cap, flat bottom and tapered heads for pressure vessels formed by pressing, spinning, rolling and splitting in whole plate or assembled plates. 1.3 The manufacture, inspection and acceptance requirements of heads for atmospheric pressure vessels and other pressure equipments may also comply with this standard by reference. 2 Normative References The following normative documents contain provisions which, through reference in this text, constitute provisions of this standard. For dated references, subsequent amendments to (excluding amending error in the text), or revisions of, any of these publications do not apply. However, all parties coming to an agreement according to this standard are encouraged to study whether the latest edition of the normative document is applicable. For undated references, the latest edition of the normative document applies.
