Wedge Test
The Wedge test for fasteners is a mechanical test method used to evaluate the tensile strength and integrity of fasteners, such as bolts, screws, or studs. It is primarily employed in quality control and material testing to ensure that fasteners meet specified standards and requirements.
In the wedge test, a specially designed wedge-shaped tool is used to apply an axial force to the fastener. The wedge is inserted into a slot or groove on the fastener, and a tensile load is gradually applied, pulling the fastener in the axial direction. The force is increased until the fastener fails or fractures.

Vickers Hardness Test
The Vickers hardness test is a method used to measure the hardness of a material. It involves pressing a pyramidal-shaped diamond indenter into the surface of the material and measuring the size of the resulting indentation.
The Vickers hardness test is widely used in quality control, material characterization, and research and development applications. It provides valuable information about a material’s resistance to plastic deformation, wear resistance, and strength, making it a valuable tool in various industries, including manufacturing, engineering, and metallurgy.
Examples of Standards/Certifications: AS 1817.1; ASTM E384; ISO 6507-1; ISO 6508-1.
Rockwell Hardness Test
The Rockwell hardness test is a widely used method for determining the hardness of a material. It measures the resistance of a material to permanent indentation or penetration by applying an external load using a diamond cone or a hardened steel ball.
The Rockwell hardness test involves two main scales: the Rockwell C scale (HRC) and the Rockwell B scale (HRB). The choice of scale depends on the specific material being tested.
The Rockwell hardness test is popular due to its simplicity, speed, and accuracy. It is suitable for a wide range of materials, including metals, plastics, and composites. The test provides a reliable measurement of hardness, which is important for assessing a material’s strength, wear resistance, and suitability for specific applications.

Charpy Impact Test
The Charpy impact test is a standardized method used to measure the toughness or impact strength of a material. It evaluates the material’s ability to absorb energy under high-strain-rate loading conditions, such as sudden impact or shock.
In the Charpy impact test, a notched or V-shaped specimen is supported at its ends and struck by a pendulum hammer. The pendulum swings downward, and its striking edge impacts the specimen at a specific point between the supports. The impact causes the specimen to fracture and break.
The Charpy impact test is conducted at various temperatures, allowing the evaluation of a material’s resistance to impact over a range of conditions. Testing at different temperatures is particularly important for assessing materials used in applications exposed to low temperatures, as their impact properties can significantly change.
The results of the Charpy impact test provide insights into a material’s behaviour under sudden impact or shock loading, its fracture toughness, and its ability to resist brittle fracture. It is widely used in quality control, material selection, and design assessment, especially in industries such as construction, automotive, aerospace, and structural engineering.
The Charpy impact test is standardized and governed by various international standards organizations, including ASTM International and ISO (International Organization for Standardization). The results of the Charpy impact test help ensure the safety and reliability of materials in applications subjected to sudden impact or dynamic loading.

Cold Flattening
Cold flattening, also known as cold flattening test or flattening test, is a mechanical test method used to evaluate the ductility and integrity of metallic tubes or pipes. It is commonly performed as part of quality control or material testing procedures to ensure that the tubes or pipes meet specific standards and requirements.
In the cold flattening test, a section of the tube or pipe is flattened using mechanical force without the application of heat. The test specimen is typically prepared by cutting a specific length of the tube or pipe and removing any internal supports or inserts.
The specific parameters and acceptance criteria for cold flattening tests may vary depending on the applicable standards, specifications, or industry requirements. The test results help ensure the reliability, safety, and suitability of metallic tubes or pipes for their intended applications, such as plumbing, structural components, or fluid transportation systems.

Pressure Testing
Pressure testing is a mechanical testing method used to assess the integrity, strength, and performance of components or systems that are designed to contain or withstand pressure. It involves subjecting the component or system to internal or external pressure to evaluate its ability to maintain structural integrity and prevent leakage under specified conditions.
In pressure testing, the component or system is pressurized using a fluid or gas, and the pressure is gradually increased to the desired level. The applied pressure is maintained for a specified duration to observe the behaviour and response of the component or system.
