GB/T 18674-2018General technical specifications for ropes for fisheries (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard replaces GB/T 18674-2002 "General technical conditions for fishing ropes". This standard is compared with GB/T 18674-2002 except In addition to editorial changes, the main technical changes are as follows.

--- Increased use of polypropylene ropes for fishing, high-strength polypropylene multifilament ropes, polyester ropes and UHMW-PE ropes (Chapter 1, 5.2.3, 5.2.4, 5.2.6, 5.2.7);

--- Replaced the original standard manufacturing and twist factor requirements with general requirements, and replaced the manufacturing and twist coefficient with GB/T 21328 Body content (5.1);

--- Modify the linear density and minimum breakage of polyamide fishing ropes, polyethylene fishing ropes, polypropylene-polyethylene mixed polyolefin ropes Requirements for strong indicators (5.2.1, 5.2.2, 5.2.5);

--- Removed pre-tension requirements in the original standard test method;

--- Removed moisture regain requirements for polyamide fishing ropes in the original standard inspection rules.
