19、er bodies). The work of preparing International Standards is normally carried out through IS0 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, government

20、al and non-governmental, in liaison with ISO, also take part in the work. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the memb

21、er bodies for voting. Publication as an International Standard requires approval by at least 75 Y of the member bodies casting a vote. International Standard IS0 5080 was prepared by Technical Committee ISOflC 38, Textiles. This second edition cancels and replaces the first edition (IS0 5080:1977),

36、se twines are not included in the International Standard. In order to make sure that these twines have the same quality level as that of the twines in this Intemational Standard, their specifications shall be calculated, as far as the minimum breaking force requirement is concerned, by means of the

A force of 1 decanewton (daN) = 1.02 kgf. is the breaking force, in decanewtons; is the runnage of twine, in metres per kilogram. 2 STD-BSI BS EN IS0 !OACI-ENGL 1797 lb2Ybb7 0777bbli 57T EN IS0 6080:1999 8 Test meth
