NOTE The thickness of burrs on exernal edges and the thickness of undercuts of internal edges can not be specified according this standard. The indicated limit deviations correspond to the maximum and minimum dimensions, respectively.When a particular direction of burr or undercut is required, the indication shall be positioned accordingly (4.4). The upper limit deviation is placed above the lower limit deviation (see Figure 10). Whenever the specification of an upper and lower limit deviation for the size of an edge is necessary, both values shall be indicated. When a single limit for the size of an edge is specified, the second limit deviation is the value 0 (zero). The value is placed after the symbol element +, – or tin the area a1(see Figure A.1). The deviation from ideal nominal shape can be controlled by indication of a size. Transition line, included in an intersection plane, which is not defined on the nominal model and which exists between two adjacent integral surfaces ISO 3098-0:1997, Technical product documentation一Lettering 一Part 0: General requirements For undated references,the latest edition of the referenced document (including any amendments) applies. For dated references, only the edition cited applies.
The following document, in whole or in part, is normatively referenced in this document and is indispensable for its application. In cases where the geometrically defined shape of an edge (for example 1×45°) is required, the general dimensioning principles given in ISO 129-1 apply. NOTE The undefined edge can only be specified in 2D drawings.
