JAPAN TESTING LABORATORIES List of Products and Services

In recent years, the demands for product safety and reliability have become increasingly sophisticated. In particular, "durability" is recognized as a very important evaluation criterion related to product failure, and it is assessed at various stages from the research and development phase to the completion phase of the product. To meet these demands, our company offers contracted fatigue testing services. We not only evaluate the materials themselves but also accommodate special component shapes and product designs, including the creation of dedicated jigs and processing for the products. Please feel free to consult with us.

This service evaluates the "strength," a type of "mechanical property" necessary for assessing materials such as metals, plastics, and ceramics, as well as products and parts like die-cast items and resin-molded products, through tensile testing. The durability of materials varies depending on their type in response to externally applied forces such as tension, compression, and shear. These properties are referred to as "mechanical properties" and serve as important indicators for evaluating processing methods and the durability of processed products. We can accommodate tests in accordance with standards such as JIS, and even for non-standard testing methods or specimen shapes, we can provide flexible support by creating jigs and processing test specimens according to the specific requirements.

This service evaluates the "mechanical properties" (strength and deformation) related to the bending of materials through a bending test (flexural test) that applies a load to the center while supporting both ends of the specimen. It is mainly used to investigate the workability of materials. At JTL, we use a tensile and compression testing machine to evaluate the following parameters: - Maximum load - Maximum stress - Young's modulus, etc.

This service provides creep testing, which involves holding a specimen at a constant temperature and applying a constant load to measure the strain that changes over time (the change in material length or the time until fracture). This test is particularly conducted for evaluating materials used at high temperatures for extended periods. Creep curves, creep strength, and time-strain can be determined. When a constant load is applied to a material and it is left for a long time, the changes increase over time, and if the limit is exceeded, it ultimately leads to failure. Tensile creep testing is conducted to determine the creep rupture life. Additionally, the time until failure is measured by varying the stress (load) and plotting it on a graph. From this curve, the relationship between the stress that leads to failure and time can be determined. *At JTL, we offer creep testing services using a tensile compression testing machine. Please consult us as there may be some testing conditions that we cannot accommodate.*

Etching is a surface processing technique that utilizes the corrosive action of chemical reactions, such as those involving chemicals. The observation pre-treatment that employs this principle is the etching of metal structures. By etching the metal surface, differences in crystal orientation and composition create unevenness, allowing for the observation of the metal structure. The size of samples that can be etched is approximately 50mm square. For observation with a metal microscope, samples can be about 50mm square in size and can be observed at magnifications of up to 1,000 times. For observation with a scanning electron microscope (SEM), samples can be up to φ180mm × t70mm in size and can be observed at magnifications of about 20,000 times.

An ion milling device is a cross-section polishing apparatus that performs polishing and etching for observation and analysis by irradiating the surface of a sample with a very weak argon ion beam. In conventional mechanical polishing, soft materials such as copper and aluminum can suffer from surface flattening and sagging, while hard materials like ceramics and silicon can experience cracking and fractures. However, the ion milling device resolves these issues, allowing for a clean and undamaged observation surface. The ion milling device is suitable for sample preparation for high-magnification observation and analysis in micro-regions, enabling the production of cross-sectional samples for sub-micron order observation, EDX/WDX analysis, crystal state observation, and crystal orientation analysis (EBSD).
