The work of preparing International Standards is normally carri

10、ed 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, in liaison with ISO, also take part in the work. I

23、a) designation of the braid yarn(s);b) construction of the sleeve;c) braid angle at a specific diameter;d) type of treatment;e) mass per metre length of the sleeve.As the full description is unwieldy, the manufacturers of tubular braided sleeves normally give a code number to their products to simpl

24、ify ordering and stocking. The full description of the braided sleeve shall, however, be given in the manufacturers catalogue against its code number.Thus, this International Standard is not meant for use in the designation of tubular braided sleeves, but is intended to be used as an aid in the prep

25、aration of standardized descriptions in the braided-sleeve catalogues and to ensure the consistency of braided sleeve identification.4.2 DesignationThe designation shall be made up of the following three groups of code-letters/numbers:a) the first group (maximum of four characters) indicates the typ

26、e or types of material used in the braiding;The following code letters shall be used to designate different types of material: G = Glass C = Carbon A = Aramid E = Ceramic P = PolyethyleneIf two or more types of material are combined in a hybrid braiding, two or more code letters shall be used.EXAMPL

27、ES CG = Carbon/glass CAE = Carbon/aramid/ceramic CGEA = Carbon/glass/ceramic/aramidIf several fibre types are used, they shall be given in order of the cross-sectional area (i.e. the mass per unit length divided by the density) of the fibre concerned, starting with the fibre having the greatest cros

28、s-sectional area.b) the second group (three digits) indicates the sleeve diameter, in millimetres, at a fibre angle of 45;c) the third group (three digits) indicates the mass, in grams per metre of sleeve, at a diameter which corresponds to a fibre angle of 45.2 ISO 2014 All rights reservedBS ISO 10
