ISO 2538-2:2014 pdf free.Geometrical product specifications (GPS)一Wedges
Wedges can be toleranced (both size and sloped feature) in accordance with the methods given in Figures 5 to 10.
The letter symbol t is used to define the width of the tolerance zone.
NOTE 1 Alternative methods of tolerancing using only dimensional specifications do not give adequate indication with regard to the shape of the surface. Consequently, when alternative methods are used geometrical specifications according to ISO 1101 have to be added if required for functional reasons (see ISO 14405-2)
NOTE 2 Generally, in this standard, to express a geometrical specification of location, the characteristic symbol of position is used. The characteristic symbol for profile of any surface can also be used with the same meaning.
The position characteristic symbol immediately gives the information that the toleranced feature is a flat surface.
The profile ofany surface characteristic symbol does not immediately give the information that the toleranced feature is a flat surface, it is necessary to analyse the indications of the whole drawing or query the CAD model of the part.
The two tolerance zones are limited by two parallel planes located a distance t apart on each side of the wedge.The plane pairs have a wedge angle β between them. The lower planes are perpendicular to datum A and the intersection lines of the planes are parallel to datum A. The height Hx applies at the distance Lx from datum A. The extracted surfaces of the wedge are required to be within these zones.

The CZ modifier locks the two tolerance zones together. Without the CZ modifier, the two tolerance zones can rotate relative to each other, such that the orientation of the tolerance zone for the upper surface is perpendicular to the drawing plane and the orientation of the tolerance zone for the lower surface is not perpendicular to the drawing plane.ISO 2538-2 pdf free download.
