FZ/T 54027-2022Ultra-high molecular weight polyethylene (UHMWPE) filament yarns (English PDF)

Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for Standardization Work Part 1: Structure and Drafting Rules for Standardization Documents" drafting.

This document replaces FZ/T 54027-2010 "Ultra High Molecular Weight Polyethylene Filament". Compared with FZ/T 54027-2010, except for editorial in addition to the modification, the main technical changes are as follows.

--- Expanded the scope of application of the document (see Chapter 1, Chapter 1 of the 2010 edition).

--- Deleted the definition of "ultra-high molecular weight polyethylene filament" (see Chapter 3, Chapter 3 of the 2010 edition).

---Classification and identification (see Chapter 4, Chapter 4 of the 2010 edition).

- Added five series of TM25, TM38, TM40, TM42, TM45;

- Canceled the classification of linear density by "low, medium, thick and high";

---Technical requirements (see Chapter 5, Chapter 5 of the 2010 edition).

- For product grading, the expression "lower than qualified products are substandard products" has been deleted;

- The numerical digits of the breaking strength index are changed from integer digits to one decimal place;

- The index value of elongation at break is adjusted from "<=4%" to "M1±0.5%, M1 is determined through negotiation between the supplier and the buyer, and M1<=5.0";

- Added 1 performance item and index. coefficient of variation of fracture strength;

- Added the performance index values of TM25, TM38, TM40, TM42, TM45 series products.

--- Appearance requirements, testing and evaluation (see Appendix A, Appendix A of the 2010 edition) - Appearance index grading, delete the expression "lower than qualified products are inferior products";

- Removed the "knot" indicator;

- Added 2 appearance indexes and index values. tripwire (cobweb thread), forming, and added its inspection steps;

- Adjusted the judgment rules.
