24、2016-05 EN ISO 2078:1994 + A1:2015 (E)1 Scope This International Standard specifies a System of designating textile glass yarns including Single, multiple-wound, folded (plied), cabled and textured yarns, Strands, slivers and rovings based on their Iin- ear density expressed in the tex System. This
25、International Standard applies the rules of the Single-to-fold designation given in ISO 1139 to these textile glass products. 2 Normative references The following Standards contain provisions which, through reference in this text, constitute provisions of this International Standard. At the time of
26、publi- cation, the editions indicated were valid. All Standards are subject to revision, and Parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most re- cent editions of the Standards indicated below.

ISO 1139: 1973, Textiles - Designation of yarns. 3 Definitions For the purposes of this International Standar
28、d, the definitions given in ISO 2 and ISO 472 apply. 4 Designation of a yarn 4.1 Elements of the designation According to the definition given in ISO 1139, the designation of a yarn (Single yarn, Strand, sliver, . . . . roving) is a condensed technical description contain- ing the following elements
29、. 4.1.1 Glass used One or several letters, to specify the glass used by the manufacturer (see table 1). 4.1.2 Type of yarn A letter to describe the type of yarn: - C (continuous) for continuous-filament yarns, - D (discontinuous) for staple-fibre yarns. NOTE 7 These letters are placed in the first g
30、roup, as it is of special importante in the case of textile glass to dis- tinguish between continuous-filament yarns and staple fibre yarns; their use makes it unnecessary to indicate the num- ber of filaments, preceded by the Symbol f, as proposed in ISO 1139. 4.1.3 Nominal diameter of fibre A numb
31、er, consisting of one or two figures, giving the nominal diameter, in micrometres, of the filament or staple fibre. 5DIN EN ISO 2078:2016-05EN ISO 2078:1994 + A1:2015 (E)4.1.4 Linear density, direction and amount of twist and number of components Some, or all, of the following elements, as in ISO 11
32、39: a) a number giving the linear density expressed in the tex System. lt is strongly recommended that the tex be used as the basic unit, in which case the word “tex” tan be omitted from the designation (if multiples or submultiples of the tex are used, these units shall be indicated after the value
33、 given for linear density); b) the direction(s) of twist;) c) the amount(s) of twist, expressed in turns per metre, for the twist of the final Stage, and (if necessary) in the full designation, for the twist of each intermediate Stage; d) the number of components in folding (plying) or cabling. 4.1.
34、5 Manufacturers code If desired, the designation may also include the manufacturers Code, permitting the incorporation of any complementary information that does not appear among the previous elements, for example the type of size and the Overall linear density. If it is included, the manufacturers
35、code shall be placed either before or after the designation as defined below and never between the elements of the designation for exam- ple in the case of folded (plied) yarns having dissimilar components. 4.2 Designation of different types of textile glass yarn Subclauses 4.2.1 to 4.2.8 give the e
36、lements that shall appear in the designation of various types of glass yarn. 4.2.1 Strands a) the type of glass used; b) the letter C for continuous-filament yarn; c) the nominal diameter , in micromet me nts, followed by a space; res, of the fila- d) the linear density, preferably in tex see 4.1.4
37、a). EXAMPLE EC10 40 4.2.2 Slivers a) the type of glass used; b) the letter D (discontinuous) for staple-fibre yarns; c) the nominal diameter, in micrometres, of the sta- ple fibres, followed by a space; d) the linear density, preferably in tex see 4.1.4 a). EXAMPLE ED7 190 4.2.3 Single yarns 4.2.3.1
38、 Single continuous-filament yarns a) the type of glass used; b) the letter C for continuous-filament yarn; c) the nominal diameter, in micrometres, of the fila- ments, followed by a space; d) e) f) EXAMPLE NOTE and Strands For twisting yarn 4.2.3.2 Single staple-fibre yarns a) the type of glass used
39、; b) the letter D (discontinuous) for staple-fibre yarns; c) the nominal diameter, in micrometres, of the sta- ple fibres, followed by a space; d) the linear density, preferably in tex see 4.1.4 a), followed by a space; e) the direction of twist, followed by a space; f) the amount of twist, expresse
40、d in turns per metre. EXAMPLE ED7 190 Z 160 1) If the yarn has been subjected to a twisting Operation, this shall be indicated by the direction of twist followed by the degree of twist. If the designation does not include any mention of twist, this shall always be taken to signify the absence of any
41、 twisting Operation. 6DIN EN ISO 2078:2016-05 EN ISO 2078:1994 + A1:2015 (E)4.2.3.3 Textured yarns a) the type of glass used; b) the letter C or D for the designation of the original yarn (see 4.1.2); c) the nominal diameter, in micrometres, of the fila- ments, followed by a space; d) the linear den
42、sity, preferably in tex see 4.1.4 a), before texturing, followed by a space; e) the linear density, preferably in tex see 4.1.4 a), after texturing, preceded by the letter T. EXAMPLE EC9 340 T352 4.2.4 Folded (plied) (doubled) yarns2) 4.2.4.1 Folded (plied) yarns having identical components a) Full
43、designation: 1) the designation of the Single continuous- filament or staple-fibre yarns used, in accord- ante with 4.2.3.1 or 4.2.3.2, followed by a space; 2) a multiplication sign, x, followed by a space; 3) the number of Single continuous-filament or staple-fibre yarns, followed by a space; 4) th
44、e direction of the folding (plying) twist, fol- lowed by a space; 5) the amount of folding (plying) twist, expressed in turns per metre. EXAMPLES ED7 190 Z 160 x 2 S 260 b) Simplified designation: 1) the designation of the Single continuous- filament or staple-fibre yarns used, in accord- ante with
45、4.2.3.1 or 4.2.3.2, without indication of the direction or amount of twist the twist of folded (plied) yarns is generally balanced, followed by a space; 2) a multiplication sign, x, followed by a space; 3) the number of Single continuous-filament or staple-fibre yarns, followed by a space; 2) This t
46、erm is defined in ISO 1139. 4) the direction of the folding (plying) twist, fol- lowed by a space; 5) the amount of folding (plying) twist, expressed in turns per metre. EXAMPLES EC934x2S150 EC9 190 x 2 S 260 4.2.4.2 Folded (plied) yarns having dissimilar components a) the designations of the Single
47、 continuous-filament yarns used, in accordance with 4.2.3.1, joined by a plus sign, +, preceded and followed by a space, the whole being placed in parentheses and fol- lowed by a space; b) the direction of the folding (plying) twist, followed by a space; EXAMPLE EC934Z150x2S100x3Z80 b) Simplified de
48、signation: The twist of cabled yarns is generally balanced, and in most cases it is not necessary to know the direction and the amount of twist of each of the intermediate stages; consequently, the simplified designation for a cabled yarn shall only show the direction and the amount of final twist.
49、The simplified designation shall therefore consist of the following elements: 1) the designation of the Single continuous- filament yarns, in accordance with 4.2.3.1, omitting the direction and the amount of twist, followed by a space; for each intermediate Stage: 7DIN EN ISO 2078:2016-05EN ISO 2078:1994 + A1:2015 (E)2) a multiplication sign, X, followed by a space; 3) the number of yarns involved, followed by a space; for the final Stage: 4) a multiplic
