Tensile testing, also known as tension testing, is a fundamental materials science test in which a sample is subjected to a controlled tension until failure.
UnitedTest systems are ideal for performing compression tests on a variety of products and materials including concrete, metal, cardboard and plastic packaging, ceramics. Most common measurement from a compression test is the compressive strength which is the maximum load a material can withstand before it yields or breaks.
Flexural strength, also known as modulus of rupture, is a material property, represents the highest stress experienced within the material at its moment of yield.
- Cycle fatigue
Fatigue is the weakening of a material caused by repeatedly applied loads. It is the progressive and localised structural damage that occurs when a material is subjected to cyclic loading.
Impact test, Test of the ability of a material to withstand impact, many materials fail suddenly under impact, at flaws, cracks, or notches. The most common impact tests use a swinging pendulum to strike a notched bar.
Torque, also called moment or moment of force, is the tendency of a force to rotate an object about an axis or pivot. Torque is rotational force. The amount of torque developed is proportional to the force applied and to how far from the center of the rotation the force is applied.
- Hardness Test
Hardness is defined as the resistance to indentation, and it is determined by measuring the permanent depth of the indentation.
- Peeling, tear
The peel strength determines the adhesive strength (also called the adhesive fracture toughness). Tear resistance is the measurement of a sample's ability to resist tearing.
- Melt flow index
The melt flow index (MFI) is a measure of the ease of flow of the melt of a thermoplastic polymer. include MFR/MVR test method. ISO 1133, ASTM D1238.
- Hydrostatic pressure
Pipeline hydrostatic pressure testing, internal pressure testing, long-term pressure holding testing. Check the strength and leakage. Test standard ISO 1167.
Heat deflection temperature (HDT) (ISO 75, ASTM D648)， Vicat softening temperature (VST) (ISO 306, ASTM D1525)
