8、 bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member 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
9、 and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.International Standards are drafted in accordance with the rules given in the ISO/IEC Directive
10、s, Part 2.The main task of technical committees is to prepare International Standards. Draft International Standards adopted 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 ca

16、 same as for sheet supplied in cut lengths but, in cases where welds are present, the tolerances shall be double those given over a length of 15 m in the vicinity of the weld.bFor specified strength levels of Re= 360 MPa and greater, increase the thickness tolerances by 10 %, applying normal roundin
17、g-off procedures.cThickness is measured at any point on the sheet not less than 25 mm from a side edge.dThe specified thickness range captions apply as a specific value.eThe tolerances provided in this table are based on normal thickness (tolerance over and under). For ordered thicknesses other than
18、 nominal, the total tolerance is twice the tabled value and may be distributed as agreed upon between the buyer and seller.Table 2 Width tolerances for coils and cut lengths, not resquaredDimensions and tolerances in millimetresSpecified width Tolerance 1 200+30 1 200 1 500+ 50 1 500+ 60NOTE For res
