Information on the most widely used ASTM standards within the materials testing industry
plastic tube, wire tensile test
Plastic tube, wire bollard tensile test grips are used on a Universal Testing Machine to perform tensile tests on filament material such as string, thread, wire and yarn. The specimen is wrapped around a bollard or post and then secured with a vise grip mechanism. The term bollard comes from the maritime industry and is used to describe a thick, short post on a ship deck or dock which is used to wrap a rope around to anchor the vessel.
Product use: The wire winding tensile fixture is the most commonly used accessory for tensile testing, which can test the elongation and tensile strength of linear materials (such as metal wire, fiber rope, etc.). It consists of two grips, the upper and lower, and the two ends of the specimen can be wound in the middle of the upper and lower grips. Before the tensile test, we need to mount the wire winding fixture on the tensile testing rig and apply force in different directions to the upper and lower grips to stretch the linear material until it breaks.
General introduction
Plastic tube, wire bollard tensile test grips are used on a Universal Testing Machine to perform tensile tests on filament material such as string, thread, wire and yarn.

Product use: The wire winding tensile fixture is the most commonly used accessory for tensile testing, which can test the elongation and tensile strength of linear materials (such as metal wire, fiber rope, etc.). It consists of two grips, the upper and lower, and the two ends of the specimen can be wound in the middle of the upper and lower grips. Before the tensile test, we need to mount the wire winding fixture on the tensile testing rig and apply force in different directions to the upper and lower grips to stretch the linear material until it breaks.
This fixture is suitable for tensile test of rope, and it is necessary to ensure that the wire rope can be wound when doing wire rope test. This fixture adopts a winding structure, which is locked and fixed after winding 3-5 times on the winding wheel, which can effectively prevent the rope from slipping or damaging the specimen after blessing and causing fracture in the jaw. For thicker ropes, this is also the case, but a larger scale clamp is required.

Standard
ASTM D2256 is the standard test method for tensile properties of yarns by the single-strand method. It is the predominant standard used in North America and is technically very similar to ISO 2062. It quantifies breaking force, elongation at break, and derived properties (tenacity, modulus, toughness) under diverse conditions, serving as a benchmark for quality control, product development, and material specification.
ISO 2062 specifies the method for determining the breaking force and elongation at break of textile yarns (single, piled, or cabled) under a constant rate of extension (CRE). It is a fundamental tensile test for yarn quality control.
The test operates on the principle of applying a constant rate of elongation to a single yarn specimen until it breaks:
A single yarn is securely clamped between two grips at a fixed gauge length.
The lower grip moves downward at a constant speed, stretching the yarn at a rate of 100% per minute of the gauge length.
The machine continuously records the force (load) applied and the corresponding elongation.
The test ends when the yarn breaks. The maximum force recorded is the breaking force, and the stretch at that point is the elongation at break (expressed as a percentage).
ISO 3341:2000 Textile glass — Yarns — Determination of breaking force and breaking elongation
ISO 3341 specifies a method for the determination of the tensile breaking force and elongation at break of glass yarns taken from packages.
The method is applicable to various types of glass yarn (single, folded, cabled, strands, structures without twist, rovings, etc.). It is basically intended for single, folded and cabled glass yarns having a diameter of less than 2 mm, or a linear density lower than 2000 tex, taken from packages.
