Abrasion and Wear Testing
Abrasion testing is used to test the abrasive resistance of metals, composites, ceramics and thick coatings. Abrasion test methods rank materials on their resistance to scratching abrasion under specific conditions.
Abrasion testing is performed to determine how materials will perform under sustained friction. Solid materials like metals, composites, ceramics and thick coatings are ranked based on their resistance to scratching under a specific set of conditions. Abrasion testing is generally performed to assist in material selection, ensure that materials are fit for purpose, or qualify parts to specific standards.
Some of the abrasion testing methods we offer include:
- Taber abrasion
- RCA abrasion
- Solder abrasion (pencil method)
- Rubber wheel abrasion
- Wyzenbeek abrasion
- Martindale abrasion
- Falling sand abrasion
Wear testing is performed when real-life conditions, such as temperature, fluids and direction of wear, must be replicated as closely as possible. Element can assist in setting up custom wear projects that can provide accurate predictions about how materials will react in use. In addition to testing metals, plastics and ceramics, Element also performs wear testing on medical devices and small components.
Some of our wear testing methods include:
- Pin-on-disc wear testing

Bend testing is a mechanical method used to measure the flexural strength of materials. It is widely used in metals and welds, as well as non-metallic and composite materials.
Bend testing is used to determine the ductility or strength of a material by flexing it over a given radius. It is particularly useful for components and materials that will are subject to folding or flexing, such as fasteners and welds. Element uses bend testing to ensure that metals, plastics, ceramics and more are fit for purpose in their intended applications.
Some of the bend testing methods we frequently offer include:
- API 1104

- ISO 7438
Compression testing uses crushing forces to determine a material's resistance to deformation. Element performs compression testing on metals, plastics, composites, and more.
Compression testing determines a material’s resistance to crushing loads. Sometimes thought of as the opposite of tensile testing, compression testing is performed by subjecting a material or product to a compressive force, and measuring how much it deflects.
Element can perform compression testing both statically and dynamically, depending on the test requirements. In addition to testing materials like metals, ceramics, plastics, foams and rubbers, we also perform testing on components and packaging.
Some of our most common compression testing methods include:
- ASTM D3039
- ASTM D395
- ASTM D6641
- ASTM D695
- ASTM E9
- ISO 815
- ISO 903
Our labs offer specialized mechanical and metallurgical testing methods for screws, bolts, nuts, and more.
Because of their crucial role in virtually every component type, fasteners are an integral part of any product, system or assembly. Our labs provide a variety of mechanical tests to ensure that these critical parts are fit for purpose, and can withstand the loads they encounter in service.
Some of the methods that we use for fastener testing include:
- Compression testing

Fracture Toughness Testing
Element offers a wide variety of fracture toughness methods to test the cracking resistance of metals, composites, plastics and more.
Fracture toughness is a value that measures a material’s resistance to cracking or fracturing. One of the most important properties of any material for virtually all design applications, fracture toughness, or K1c, is particularly important for environments and materials where brittle fracture is common. We frequently provide fracture toughness testing for clients in aerospace, oil and gas, medical device, and more.
Some of the methods Element most frequently tests include:
- API 1104
- ASTM B645
- ASTM D5528

- BS EN ISO 12737
Used to determine how materials will behave under cyclic loading, fatigue testing data is widely used in research and development plans, material characterization programs, and more.
Fatigue testing evaluates the effects of cyclic loading on materials over time. This method can be used to find the failure point of materials, investigate failures in the field, or simulate real-world conditions. We perform fatigue testing on metals, ceramics, plastics, and more, as well as medical devices and some components.
Fatigue testing is generally split into two main groups: high cycle fatigue (HCF) and low cycle fatigue (LCF). Element provides testing for both types, and can assist in choosing the most appropriate method for your material.
Some of our more popular fatigue testing standards include:
- BS 4449
- ASTM D3479
- ASTM D4482
- ASTM E466
- ASTM E606
- ASTM F1160

- ISO 1143
Hardness measures the resistance of a material to indentation by physical force, and is closely related to other material properties, such as tensile strength and compressive strength.
Due to its versatility and fast turn-around times, hardness testing is one of the most popular mechanical test methods we perform. Used in materials selection, lot verification testing, material processing, and more, hardness testing can be performed on multiple material types.
Element performs hardness testing to a wide range of scales, and is one of the only commercial labs in the world to offer hot hardness testing. Our hardness methods include:

Impact testing is used to measure how much energy a material an absorb under force. Element offers several methods for testing impact resistance, including Charpy impact testing and Izod impact testing.
Charpy and Izod impact testing are high-strain methods that determine the amount of energy absorbed during fracture. During testing, a pendulum strikes a pre-machined sample, and data about impact is collected.
Charpy is usually performed on metals, and Izod is generally a plastics test. Element can perform testing with both standard and sub-sized samples.
Some of the impact testing methods we use include:
- ASTM A370
- ASTM A923

Pressure testing uses air or water to test the pressure limits of materials in high-pressure applications.
Pressure testing uses water or air to pressurize components and vessels and check for leaks or defects. It can also be performed to provide pressure ratings for products, and predict how components will react in high-pressure environments.
The two main types of pressure testing we provide are hydrostatic testing (water/liquid pressure) and pneumatic testing (air pressure). Our labs can help you determine which method works best for your project.
Element can assist with custom test designs and set-ups for projects that require specialized procedures. For more information about the pressure testing methods we use, contact an expert today.
Shear testing is characterized by a sliding failure, and measures the strength of materials along parallel planes. Our labs can test single and double lap shear, in-plane shear, and more.
Shear testing measures a material's response to shear loading, a sliding failure along a plane parallel to the direction of force. Element performs testing on metals, plastics, composites and laminates, and more. Additionally, we provide shear testing programs for products that experience sliding stress, including bolts, rivets, pins, and other products.
Element offers a variety of shear testing methods to accommodate a variety of material and component types. Some of the tests we commonly perform include:

One of the most popular methods for almost every material testing program, tensile testing is a method that applies tension on a material until failure. A single tensile test can provide a variety of material properties, including yield, elongation, ultimate tensile strength (UTS), Poisson’s ratio, and more.
