25、:6673 O3002(E) iv I SO 3002 All irthgs ersedevrForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each me
26、mber body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International E
27、lectrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards ad
28、opted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of pa
29、tent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 3766 was prepared by Technical Committee ISO/TC 10, Technical product documentation, Subcommittee SC 8, Construction documentation. This third edition cancels and replaces the second edition (ISO 3766:1
30、995) and ISO 4066:1994, which have been technically revised.

31、he characterization of reinforcement in reinforced and in prestressed concrete for use in construction drawings. It also establishes a system for the scheduling of reinforced bars, comprising a method for specifying dimensions, a coding system for bar shapes, a schedule of preferred shapes, and a sh

The representations shall correspond with the indications in the structural calculations and should,

Drawings used for off-site casting and factory production are excepted from this provision. Reference shall be referred to accessory drawings. For drawings modified later,
36、 all concerned drawings shall be modified as well.

The following information on bending the reinforcement bars shall be given on the drawing or on separate documents such as a bar schedule: if the shape coding system according to 6.3 is applied, bending shapes of the reinforcement bars shall refer unamb
