This category encompasses specialized testing equipment for evaluating the strength, durability, and safety of building structures and mechanical components. It includes tensile, compression, and bending test machines for steel structures, compression strength testers for concrete structures, fatigue testing machines for welded joints, vibration test equipment for mechanical parts, and impact testing machines. Used for structural inspection in construction industry, component quality control in manufacturing, and material evaluation in R&D, these systems enable testing compliant with JIS and ISO standards. Distinguished from material testing machines by being large-scale testing facilities designed for actual structures and finished components, clearly differentiated from single-material property evaluation equipment.
