Print Reading for Engineering and Manufacturing Technology. 10.1 Definition The envelope requirement according to ISO 8015 specifies that the surface of a single feature of size (cylindrical surface or a feature established by two parallel opposite plane surfaces) should not violate the imaginary envelope of perfect (geometrical ideal) form at maximum material size. The envelope requirement may be specified either • by indication of the symbol placed after the linear (size) tolerance, when applicable to a selected individual feature; • by indication in the drawing title box 'ISO 2768 -E', when applicable to all features of size in addition to the general geometrical tolerances according to ISO 2768; • by a national standard, e.g. ASME Y14.5M or DIN 7167, when applicable to all features of size. The envelope requirement cannot be applied to features for which a straightness or flatness tolerance is specified that is larger than the size tolerance. According to ASME Y14.5M, the envelope requirement also does not apply to features for which a straightness tolerance of the axis (even if smaller than the size tolerance) is specified. The envelope requirement may also be indicated by a form tolerance with 0 applied, see 9.3.4.
