This standard describes the methods of dimensioning and indicating the geometric tolerance of the shape of profiled lines and profiled super-lines. The methods described are related to the points of the UNI 7226/1:ISO 1101 standard which deal with the "shape tolerance of any line" and the "shape tolerance of any surface".
