IEC 60191-1:2007 gives guidelines on the preparation of outline drawings of discrete devices. For preparation of outline drawings of surface mounted discrete devices, IEC 60191-6 should be referred to as well. The main changes from the previous edition are as follows:
- requirement added for SI-dimensions for new drawings to be published;
- former rules concerning inch-dimensions are given in an informative annex;
- former rules for coding are given in an informative annex; incorporation of the supplements;
- updating of references and
- restructuring and renumbering.
