Forword
This document is drafted in accordance with the provisions of GB/T 1.1-2020 "Guidelines for standardization work: Part 1: Structure and drafting rules for standardization documents".
This document replaces FZ/T 63020-2013 "Mixed polyolefin fibre ropes", compared with FZ/T 63020-2013, except for editorial changes, the main technical changes are as follows:
--Modified "Scope" (see chapter 1, chapter 1 of the 2013 edition);
-Modification of the "Normative references" and "Identification" (see chapters 2, 4, 2 and 4 of the 2013 edition); -Addition of "Terms and definitions" (see chapter 2, 4 of the 2013 edition) -Addition of "Terms and definitions" (see Chapter 3);
--Minimum breaking strength is divided into indicators for both test methods with and without eyelets inserted at both ends (see Chapter 7, Chapter 5 of the 2013 edition);
--The "Informative Appendix" has been deleted.
This document has been amended to adopt ISO 10572:2009 "Mixed polyolefin ropes".
The following structural and editorial changes have been made to this document compared to ISO 10572:2009 "Mixed polyolefin ropes":
--To harmonise with existing standards, the scope of chapter 1 specifies the wire density and rope designation; --To harmonise with existing standards, the scope of chapter 1 specifies the wire density and rope designation
--The test methods in chapter 8 have been added for consistency with the structure of the existing standard! Chapter 9 on inspection rules and Chapter 10 on marking, packaging, transport and storage.

3 Terms and definitions
The terms and definitions defined in GB/T40273 are used in this document.
4 Marking
The marking of fibre ropes consists of the following elements:
--Fibre rope;
--The number of this document;
--Rope construction;
--Rope code
--Rope material.
Example: 3 strands of mixed polyolefin fibre rope, reference code 20 (type A), with a linear density corresponding approximately to 18l ktex Rope made of mixed polyolefin fibre.
Fibre ropes FZ/T 63020-A-20-PO
5 Materials
The raw material of the rope, should use the new by 15% ~ 50% of polyethylene and polypropylene melt blending spinning from the two-component fibres.
6 General technical requirements
6.1 Mixed polyethylene warp fibre ropes are divided into the following 4 structure types.
6.2 Structure type, twist pitch, manufacture, labelling, packaging, metering, length and deviation shall conform to the requirements of ISO 9554.
