Key Feature
During the experiment, the load should be increased steadily and without impact before reaching 75% of the specified failure load. Then, the load should be increased at a rate of 35% -100% of the specified bending failure load per minute until the test specimen fails (obvious failure phenomenon can be observed, or the load indication value of the testing machine no longer increases). At this time, the load value is the bending failure load of the test specimen.
For pillar insulators, the load should be steadily and without impact increased before 50% of the specified failure load. Then, the load should be increased at a rate of 35% -100% of the specified bending failure load per minute until the test specimen fails (obvious failure phenomenon can be observed, or the load indication value of the testing machine no longer increases). At this time, the load value is the failure load of the test specimen.
If only a withstand load test is required, the load shall be increased to the standard specified test load. If the test specimen does not damage under this load, this test shall be passed.
During the experiment, the load should be uniformly and without impact raised to the specified individual load values, and kept under this load for 10 seconds. The test sample should not be damaged, the adhesive should crack (excluding small gaps between the adhesive and metal accessories), or there should be obvious permanent deformation of the metal accessories, as well as obvious displacement phenomena between various parts.
When using a four-way (or multi-directional) load test, the load should be immediately removed (or the specific product standard residence time should be used) after the test load is added to the specified test load value. The test sample should not be damaged, the adhesive should not crack (excluding small gaps between the adhesive and metal accessories), or there should be obvious permanent deformation on the metal accessories and obvious displacement phenomena between various parts. For each direction of the experiment, the sample should be rotated 90 degrees. Angle (or angle calculated based on the number of test directions).

The complete post insulator is installed on a rigid support, and a bending load is applied to the free end of the test specimen. The offset at each load point is measured at 20%, 50%, and 70% of the mechanical failure load.
