AS 1049:2000 pdf free download – Telecommunications cables—lnsulation, sheath and jacket.
AS 1049 specifies the material requirements of the finished products and some of the compounds used to manufacture telecommunication cables and provides test methods to evaluate the properties specified.
The Standard specifics the composition, physical, electrical requirements and test methods of various materials, insulation, sheath and jacket as follows:
(a) Sections 2 to 15 Sections 2 to 15 specify the requirements of the compounds and finished products.
(b) Appendices A to Al Appendices A to Al provide a set of reference test methods for determination of compliance with the requirements of this Standard.
NOTE: Appendix AJ provides recommendations for purchasing guidelines to be supplied at the time of enquiry or order of the cable.
This Standard does not cover cables using materials that are semi-conductive.
This Standard does not include such aspects of telecommunication cables as spacers or cores in co-axial cables.
This Standard does not include dimensions or electrical requirements of completed cables.
1.2 APPLICATION This Standard is intended for use by the following:
(a) Polymer manufacturers, to form the basis of the raw material quality control procedures for the manufacture of PE and PA 12 compounds.
(b) Cable manufacturers, to form the basis of the cable material quality control procedures for the manufacture of a range of insulation, sheath and jackets of different materials.
(c) Cable end-users, to form the basis of the cable acceptance procedures for the completed cable.
For different cable materials, tests are performed on—
(I) compounds:
(ii) insulation, sheath and jacket materials taken during manufacture: and
(iii) insulation, sheath and jacket materials taken from completed cable.
These requirements are summarized in Table 1.1.
41 SCOPE This Appendix sets out the method of determining the visual appearance for insulation. sheath or jacket.
Al PRlClPLE A sample of insulation, sheath or jacket is visually inspected for defined defects.
.43 APPARAII.TS The apparatus shall comprise an Inspection area meeting the requirements of—
(a) a colour matching booth meeting the minimum specification of AS 404)4 for daylight illuminant: or
(b) a colour assessment area illuminated by either natural daylight from north-facing windows or fluorescent tubes of correlated colour temperature 6500 K. colour rendering index greater than 92 and minimum illuminance of’ lO0() lx.
A4 TEST SPEC’IME The test specimen shall be a suitable length of the insulation. sheath or jacket.
A5 CO%I)lTlOlG The material shall be conditioned at 23 2°C for a minimum of 16 h.
A6 PROCEDIRE Directly after conditioning, the test shall be conducted at 23 2°C. The test specimen shall be visually inspected with normal or corrected vision without magnification in the inspection area. The following material characteristics shall be inspected:
(a) Smoothness Thc test specimen shall be smooth and free of regular roughness such as ‘orange peel’ and any other defects such as bubbles, open spots. rips, tears, Cuts, abrasion or foreign material.
(b) TacAine’s.s The test specimen shall be free of tackiness from internal means such as surface exudation or by externally applied means suh as inks, markings or accidentally applied material.
A7 REPORT The condition of insulation, sheath or jacket shall be reported as exhibiting defects or not exhibiting defects.
