  Ball and socket couplings of string insulator units test According to IEC60120-2020,ANSI/NEMA C29.2B-2013

  The tolerance for the gauges follows the connection standard. For the ball eye, ball clevis, and socket clevis, test gauge is a necessary way to control quality. The “GO” gauge should ask all parts pass through, and the “NO GO” gauge should ask all parts not pass through, only the two gauges both act well, the pars can pass the test gauge.

  Rockwell Hardness Test According to ASTM E18-2019 / Brinell Hardness Test According to ASTM E10-2018

  The application of hardness testing enables you to evaluate a material’s properties, such as strength, ductility and wear resistance, and so helps you determine whether a material or material treatment is suitable for the purpose you require,Especially after heat treatment, it can ensure the performance of the material after heat treatment.

  Magnetic particle test standard practice According to ASTM E1444/E1444M-2016

  The magnetic particle testing method is used to detect cracks, laps,seams,inclusions,and other discontinuities on or near the surface of ferromagnetic materials.Magnetic particle testing may be applied ti raw material ,billets,finished and semi-finished materials,welds,and in-service parts.Magnetic particle testing is not applicable to non-ferromagnetic metals and alloys such as austenitic stainless steel.
