ISO 6259 Determination of the Tensile Properties of Thermoplastics Pipes Tensile tests on specimens made of thermoplastics pipes are used for the characterization of the material behavior in the processing state. The ISO 6259 series specifies a procedure for determination of the tensile properties of thermoplastics pipes, including the following: Stress at yield and strain at […]

Why vibration is important for packaging? In the field of packaging and transportation, it is crucial to ensure that products can safely reach their destination. During transportation, packaging will experience various complex dynamic loads, among which vibration is a very common and significant one. In order to scientifically evaluate the bearing capacity of packaging under vibration environment,

Ring Stiffness, Ring Flexibility testing As to ISO 9969 or ASTM D2412, initial ring stiffness or ring stiffness characterizes the resistance of a pipe section to radial compressive forces. The measurement occurs at low deformations of 3%. As to ISO 13968, it describes the ability of a pipe to withstand deformation without undergoing structural damage. The test arrangement

What is Creep Test? Creep test is a material mechanical property test that measures the slow plastic deformation phenomenon of metal materials under long-term constant temperature and constant stress. The higher the temperature or stress, the more significant the creep phenomenon. Creep can occur under a single stress (tension, compression, or torsion) or under composite

ASTM D3410 is a test standard for determining the in-plane compressive properties of high-modulus fiber-reinforced polymer matrix composites. This test method is designed to generate compressive performance data for CFRP (carbon fiber reinforced polymer), primarily used in the aerospace industry for material specification, research and development, quality assurance, and structural design and analysis. Test Fixture

ASTM D6641 is currently the most widely used test method for compressive properties of composite materials in industry. This method can measure the compressive strength and stiffness of polymer-based composite materials. Compared to other methods, its application of extrusion and shear forces on the perpendicular surface has less impact on compressive strength, resulting in a

ASTM D648 for Deflection Temperature of Plastics The heat deflection temperature (HDT) describes the temperature at which a plastic material starts to deform under a predetermined load. This value is used in materials testing to evaluate the thermal resistance of a material. It is measured by subjecting a defined specimen to an increasing temperature under constant load

ASTM D3574 Standard Test Methods for Flexible Cellular Materials—Slab, Bonded, and Molded Urethane Foams ASTMD 3574 apply to slab, bonded, and molded flexible cellular products known as urethane foams. Urethane foam may be generally defined as an expanded cellular product produced by the interaction of active hydrogen compounds, water, and isocyanates. Summary of Test methods

ASTM D1894 coefficient of friction plastic films and sheeting This test method covers determination of the coefficients of starting and sliding friction of plastic film and sheeting when sliding over itself or other substances at specified test conditions. The procedure permits the use of a stationary sled with a moving plane,or a moving sled with a stationary plane. Both procedures yield the same coefficients of friction values for a given sample.

ASTM D882 Standard Test Method for Tensile Properties of Thin Plastic Sheeting ASTM D882 is a standard test method for determining the tensile properties of thin plastic films with a thickness of less than 1.0 mm (0.04 in) and is of great importance in the film packaging industry, both for quality control and research and development.
