At Benkan Kiko, we can accommodate various types of "hardness tests."
Among the various tests associated with pipe fittings, there is a "mechanical test" that examines the mechanical properties of the product. One of these tests, the "hardness test," measures hardness by pressing a hard indenter (such as diamond) into the surface of a test piece or product with a constant load using a hardness testing machine. There are several types of "hardness tests," and Benkan Kiko is capable of accommodating each of them. The types of hardness tests include the following: ▻ Brinell hardness test (HBW) ▻ Vickers hardness test (HV) ▻ Rockwell hardness test (HRCW or HRBW, etc.) Benkan Kiko has extensive experience in mechanical testing, and we accept requests not only for tests associated with pipe fittings but also for mechanical tests alone. If you have any concerns, please feel free to consult us. Details of the tests are explained in detail on our company blog.
