21、er to achieve a uniform presentation of all outline drawings for frequency control and selection devices the following guide shall be considered: 2.2 An outline drawing shall show all dimensional and geometrical characteristics of an enclosure necessary to ensure mechanical interchangeability with a
22、ll other enclosures of the same outline. Enlarged detailed view may be used, if necessary. 2.3 The outline drawing shall consist of three parts: 2.3.1 A drawing with dimensional symbols (capital letter) as shown in Figure 1 below with applicable notes, if necessary. 2.3.2 A tabular listing relating
23、to the drawing symbols to the actual dimensions. Where possible this shall be shown on the same page as the drawing. 2.3.3 An “actual-size“ sketch (scale 1:1). 2.4 The outline drawing shall be executed in the third angle projection. 2.5 The function and identification of the lead connections (termin
24、ation) shall be determined by agreement between the supplier and user. They shall not be defined on the outline drawing. 2.6 Descriptive notes may be used at the bottom of/ or adjacent to, the drawing with proper reference to the body of the drawing. 2.7 All dimensions shall be in millimeters. 2.8 O
