Description

AS 1049.2, 2nd, 2022 – Telecommunication cables – Insulation, sheath and jacket, Part 2: Test methods

AS 1049.2 was prepared by the Australian members of the Joint Standards Australia/Standards New Zealand Committee CT-001, Communications Cabling, to supersede AS 1049.2—2008.
The objective of this document is to specify test methods to evaluate the properties of materials used to manufacture telecommunication cables. This document is intended for use by polymer manufacturers, communication cable manufacturers and end-users.

AS 1049 is divided in two parts, as follows:

AS 1049.1, Telecommunication cables — Insulation, sheath and jacket, Part 1: Materials

AS 1049.2, Telecommunication cables — Insulation, sheath and jacket Part 2: Test methods (this document)
Part 1 specifies the material requirements for the insulation, sheath and jacket of the finished products and some of the compounds used to manufacture telecommunication cables.
Part 2 provides a set of reference test methods for evaluating these material requirements.

The major changes in this edition are as follows:

(a) Removal of Appendix C Test method 3: Softness number.

(b) Correction of the ASTM G155 weatherometer apparatus types in Appendix E.

(c) Addition of thermogravimetric analysis as per IEC 60811-605 as an alternative test method for the determination of the carbon black concentration in Appendix R.

(d) Apparatus changed from as specified in AS/NZS 2122.2 to as specified in ISO 4589-2 for the combustion test in Appendix DD.

(e) Update of reference designation from AS/NZS 1660.5.4 to AS/NZS IEC 60754.2 for the acidity of gases evolved during combustion test in Appendix EE.

(f) General update to meet the requirements of Standards Australia drafting rules, including dividing test methods into consistent subclauses (where appropriate) and the addition of the test report subclause where previously missing.

The terms “normative” and “informative” are used in Standards to define the application of the appendices or annexes to which they apply. A “normative” appendix or annex is an integral part of a Standard, whereas an “informative” appendix or annex is only for information and guidance.
