1 Scope
This part specifies the requirements and test methods for the mechanical and physical properties of non metal reinforcement for optical fiber cables - aramid yarn, such as linear density, breaking strength, breaking tenacity, elongation at break, force at specified elongation and chord modulus.
This part is applicable to non metal reinforcement for optical fiber cables - aramid yarn.
2 Normative references
The following documents contain provisions which, through reference in this part of YD/T 1181, constitute provisions of this part. For dated references, subsequent amendments (excluding corrections), or revisions, of any of these publications do not apply. However, parties to agreements based on this part are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest editions apply to this part.
ISO 1889: 1997 Reinforcement yarns - Determination of linear density
ASTM D885-04 Test methods for tire cord, tire cord fibers and industrial spinning made of organic fibers
3 Terms and definitions
For the purposes of this part, the following terms and definitions apply.
3.1
linear density (LD)
the mass per unit length of the yarn. There are usually two systems of units (rex system is used in this part):
——tex, which defines the mass (g) of yarn per 1,000 m, i.e. tex = g/1,000 m, and dtex = 0.1 tex = g/10,000 m.
——den, which defines the mass (g) of yarn per 9,000 m, i.e. den = denier = g/9,000 m.
Note: 1dtex=0.9den.
