The work of p
26、reparing 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 and non-governmental,
27、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. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Pub
28、lication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard ISO 2398 was prepared by Technical Committee ISO/TC 45, Rubber and rubber products, Subcommittee SC 1, Hoses (rubber and plastics). This fourth edition cancels and rep
29、laces the third edition (ISO 2398:1987), which has been technically revised.

30、two classes of rubber hose for compressed air up to a maximum working pressure of 2,5 MPa and a hose operating-temperature range of between 40 C and + 70 C, depending on the class. 2 Normative references The following standards contain provisions which, through reference in this text, constitute pro
