This issue differs from issue 4 in that the standard no longer applies to new design. For new designs, standards STD 112-0003, STD 112-0004 (Volvo Group), VCS 5062,29 and VCS 5062,39 (Volvo Car Corporation) shall be used. This standard conforms to SS-ISO 1101-1984 with the following exceptions: − The standard contains measuring principles and rules for measuring which are to be followed when interpreting the requirements. This is not included in ISO 1101. − A cylindrical tolerance zone is defined at angularity of a line. This is not done in ISO 1101. − At Volvo, theoretically exact dimensions need only be framed if there is risk of misinterpretation. According to ISO 1101, the values shall always be framed. − The standard contains rules for the evaluation of abstract (unreal) features. This is not included in ISO 1101. − The rule stating that a negative deviation of 0,01 x the length may be deducted from the extension of the toleranced feature is not included in ISO 1101. − The fact that tolerance on profile of any line and tolerance on profile of any surface can be specified in relation to datums is in this standard shown under positional tolerances and is then called position of any profile and position of any surface respectively. ISO 1101 states only that tolerance on profile of any line and tolerance on profile of any surface can be specified in relation to datums.

The standard comprises principles of symbolisation and indication on technical drawings of tolerances of form, orientation, position and run-out, and establishes the appropriate geometrical definitions. The term ”geometrical tolerances” will be used in this standard as synonymous with these tolerances. Geometrical tolerances shall be indicated with respect to the function requirements. Manufacturing and inspection requirements may also influence the way in which geometrical tolerances are specified. The indication of geometrical tolerances does not mean that a specific method for manufacture, measurement and inspection is required. This standard also contains measuring principles and certain rules for measurement which are not included in ISO 1101.
A geometrical tolerance for a feature defines the tolerance zone within which this feature shall be contained.
A feature is a specific characteristic of a part, such as axis, median plane, surface, hole, recess or profile.
Depending on the characteristic which is to be toleranced and the way in which it is indicated, the tolerance zone is one of the following: − the area within a circle − the area between two concentric circles − the area between two equidistant lines or between two parallel straight lines − the space within a cylinder − the space between two coaxial cylinders − the space between two equidistant surfaces or two parallel planes − the space within a bent pipe
The toleranced feature may be of any form or orientation within the tolerance zone in question unless a more restrictive indication is given, for example by an explanatory note.
The tolerance applies to the entire length or surface of the toleranced feature unless otherwise indicated.

. the use of a superimposed line/surface is presumed. shall be compared with the lower cost for verification.8 Establishing size of form deviation and extension of toleranced feature
The straightness or flatness of an individual toleranced feature is deemed to be correct when the distance from its individual points to a superimposed line or surface of ideal geometrical form is equal to or less than the value of the specified tolerance. When establishing the size of the form deviation in accordance with the tolerance definition. The orientation of the ideal line or surface shall be chosen so that the maximum distance (h1 in figure 1) between it and the actual profile or surface of the feature concerned is the least possible value. When measuring is carried out from a tangent line/surface.Corporate Standard
This standard is valid when there is a reference to it. The above rule leads to the least possible rejection when the feature in question is checked.B1 h1 h1 < A2 . This leads to a greater rejection which.B3 h3 h3
Therefore. we get deviations that are equal to or greater than those obtained when measuring from superimposed line/surface. A simpler method is the use of a tangent line/surface as below. Determination of the form deviation from a tangent line/surface shall be applied when a measuring principle indicating this is specified on the drawing.
