Some recognized tests for steel bar reinforcement to check the quality
Various types of tests are available for steel bar reinforcement and among them most common tests are tensile test, bending test and chemical analysis.
Chemical analysis is conducted by an expert to determine the quantity and quality of chemical elements in specific products ranging from steel bar reinforcement, structural steel as well as round or flat slab.
Given below, the details of various tests and quality checking document.
Mill Certificate
It stands for a quality checking document that is utilized in metal industry ensuring a metal product adheres to the international standards. It approves both the chemical & physical properties. The document offers the end users to verify that the supplied raw materials are abided by the order requirements. Besides, the document also facilitates to trace the materials from the beginning phase to inclusion in finished section.

Bending Test
A bending test belongs to a cost-effective qualitative test that is conducted to ascertain the flexibility & strength of materials. Bend tests distort a steel material in the middle inducing a bend to develop devoid of a fracture. As a result, the resistance level of the material is obtained.
The bending test can ensure weather a material will break down under pressure specifically in construction process.
Tension Test
A tension test is conducted for materials and it offers the information concerning the tensile strength, yield strength and the electricity of the sample. The purpose of the test is to find out how the material behaves if any force is enforced on it. Generally, the metal is pulled to recognize the tensile strength, yield strength and how much it will elongate.
The tension test offers the following benefits :-
- Forecasting the performance of the material in operation under normal & severe forces.
- Determine the requirements specification to fulfill the regulation of the contract.
- Creating a basis for technical communication.
Yield strength test
Under this test, a steel sample is chosen whose cross-section area is already established, then pull it with a controlled force that is increasing slowly until the metal alters its shape or breaks.
When a metallic material presents a yield phenomenon, a point is attained during the test at which plastic deformation happens devoid of a surge in the force.
Chemical analysis
The chemical analysis is carried by a analyst to examine the chemical contents of a sample and define the composition, structures as well as material properties from the atomic scale up to molecule scale.
Generally, the chemical analysis is performed to verify the chemical content level in some steel materials which are applied for different types of constructions like apartment, bridge, fly over, and much more.
