BS 4674 is a standard that covers breaking load and knot breaking load of netting yarns for fishing nets, enabling high strength and durability in fishing operations.
BS 4674 deals with the determination of breaking load and knot breaking load of netting yarns for fishing nets.
BS 4674 tests may be carried out in both the dry and wet state, but tests in the wet state on the knotted yarn are considered to be particularly appropriate in indicating the behaviour of the yarn in use.
BS 4674 on breaking load and knot breaking load of netting yarns for fishing nets applies to:
A fishing net is a net in which yarns are fused and knotted at their intersections. Knot breaking load is the breaking load, equal to the maximum load observed during a breaking test on netting yarn with a weaver’s knot. Breaking load is the maximum load observed during a breaking test.
BS 4674 provides users guidance on a method for determining breaking load and knot breaking load of netting yarns for fishing nets. BS 4674 also provides users with a step-by-step procedure for the method, enabling users to do the technique correctly.
BS 4674 provides users guidance on principle, apparatus, atmosphere for conditioning and testing, sampling, preparation of specimens, requirements for testing, number of tests, testing procedure, calculation, expression of results, and test report, enabling accuracy in determining breaking load and knot breaking load of netting yarns for fishing nets.
With obedience and compliance to BS 4674, users can determine the breaking load and knot breaking load of netting yarns, enabling the prevention of knot breaking load, strength and longevity in fishing nets.
