It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For this reason, the consistency of results between different test methods or under different field conditions is not very good.

It gives guidance on setting up a suitable apparatus and covers test and reporting procedures and aastm to be taken. It permits deviations from some of these conditions if properly documented, that may be appropriate for some purposes. Link to Active This link g3 always route to the current Active version of the standard.

The result would not be representative of a t32 application, where the hydrodynamic generation of cavitation is independent of the coating. For specific safety warning information, see 6.

ASTM G32 – 10 Standard Test Method for Cavitation Erosion Using Vibratory Apparatus

Historical Version s – view previous versions zstm standard. Test Method G73 describes another testing approach specifically intended for that type of environment. The latter may be more suitable for materials not readily formed into a precisely shaped specimen. This is because the compliance of the coating on the specimen may reduce the severity of the liquid cavitation induced by its vibratory motion. An alternative method for similar purposes is Test Method Gwhich employs a cavitating liquid jet to produce erosion on a stationary xstm.

It also specifies standard reference materials that must be used to verify the operation of the facility and to define the normalized erosion resistance of other test materials. However, adaptations of the basic method and apparatus have been used for such purposes see 9. Small differences between two materials are probably not significant, and their relative ranking could well be reversed in another test.

The method therefore offers a small-scale, relatively simple and controllable test that can be used to compare the cavitation erosion resistance of different materials, to study in detail the nature and progress of damage in a given material, or — by varying some of the test conditions — to study the effect of test variables on the damage produced.

The results of either, or anycavitation erosion test should be used with caution; see 5. The vibration induces the formation and collapse of cavities in the liquid, and the collapsing cavities produce the damage to and erosion material loss of the specimen.

Astk permits deviations from some of these conditions if properly documented, that may be appropriate for some purposes. The vibration induces the formation and collapse of cavities in the liquid, and the collapsing cavities produce the damage to and erosion material loss of the specimen.

In that method, the specimen is fixed within the liquid container, and the vibrating tip of the horn is placed in close proximity to it.

The stationary specimen approach can also be used for brittle materials which can not be formed into a threaded specimen nor into a disc that can be cemented to a threaded specimen, as required for this test method see 7.

However, adherence to this test method in all other respects will permit a better understanding and correlation between the results of different investigators.
