Standard

ISO 6892-1 Metallic materials - Tensile testing

ISO 6892 specifies the method for tensile testing of metallic materials and defines the mechanical properties which can be determined at room temperature.  Related standard ASTM E8 , JIS Z2241 Method of tensile test for metallic materials.

ASTM A1061, A416 Multi-Wire Steel Prestressing Strand Tensile Elongation Test

ASTM A1061 tensile test for breaking elongation stress relaxation on steel wire deals with the standard types and grade requirements of seven-wire, uncoated steel strands for use in the construction of pre-tensioned and post-tensioned pre-stressed concrete. 

The two types of strand specified by the ASTM A1061 specification are low-relaxation and stress-relieved (normal relaxation). The base metal shall be made of carbon steel and shall undergo stranding and continuous thermal and mechanical treatment. Final product requirements of ASTM A1061 shall be furnished on reels or in reelless packs for packaging and marked with two strong tags for identification. The requirements specified in ASTM A1061 shall also be applicable for pre-stressed ground anchor construction.

ASTM E290 Metal Bend testing of materials ductility

ASTM E290 Standard Test Methods for Bend Testing of Material for Ductility


ASTM E290  test methods cover bend testing for ductility of materials. Included in the procedures are four conditions of constraint on the bent portion of the specimen; a guided-bend test using a mandrel or plunger of defined dimensions to force the mid-length of the specimen between two supports separated by a defined space; a semi-guided bend test in which the specimen is bent, while in contact with a mandrel, through a specified angle of bend or to a specified inside radius of bend (r) measured while under the bending force; a free-bend test in which the ends of the specimen are brought toward each other, but in which no transverse force is applied to the bend itself and there is no contact of the concave inside surface of the bend with other material; a bend-and-flatten test, in which a transverse force is applied to the bend such that the legs make contact with each other over the length of the specimen.

ISO 7438 Metallic materials Bending test details

ISO 7438 is a standard that specifies a method for determining the ability of metallic materials to undergo plastic deformation in bending. It is used to evaluate the flexural strength and stiffness of a material , The bend test shall be carried out in testing machines equipped with a bending device with two supports and a former; bending device with a V-block and a former; bending device with a clamp. 

ISO 15630-3 Testing of Prestressing Steel Strands Relaxation, Fatigue, Tensile testing

ISO 15630-3 Steel for the reinforcement and prestressing of concrete — Test methods — Part 3: Prestressing steel

This standard specifies test methods applicable to prestressing steel (bar, wire or strand) for concrete.

ISO 15630-3, ASTM A416 and ASTM A1061 test standards offer guidelines for testing steel strands. Manufacturers of steel strands are required, through product standards, to test their products using both static and dynamic conditions.

ISO 527-4, ISO 527-5 Tensile Test on fibre-reinforced Composites

ISO 527-4 and ISO 527-5 are two key standards within the ISO 527 series for determining the tensile properties of fibre-reinforced plastic composites. 

ISO 527-4 covers the general principles and tests for isotropic and orthotropic materials. ISO 527-5 provides specific procedures for testing unidirectional fiber-reinforced composites.


These standards are critically important because they provide a unified, reliable method to measure fundamental mechanical properties (like tensile strength, modulus, and strain) which are essential for material selection, quality control, structural design, and R&D in aerospace, automotive, wind energy, and sports equipment industries.


ISO 15835 Steel Rebar Reinforcement couplers tensile test

ISO 15835-1:2009 specifies requirements for reinforcement couplers, hereafter called couplers, to be used for splicing of steel reinforcing bars. For couplers to be used for mechanical splices in reinforced concrete structures under predominantly static loads and additional requirements for couplers to be used in structures subject to high cycle elastic fatigue loading and/or to low cycle elastic-plastic reverse loading.

ISO 15835-1:2009 is intended to be applicable in relation to the various reinforced concrete design standards as well as in relation to the various standards for steel reinforcing bars. also provides directions for the evaluation of conformity of couplers.
