It gives guidance on awtm up a suitable apparatus and covers test and reporting procedures and precautions to be taken. The inch-pound units given in parentheses are for information only.

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

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. The method therefore offers a small-scale, relatively g23 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 v32 of test variables on the damage produced.

It permits deviations from some awtm 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. Link to Active This link will always route to the current Active version of the standard.

However, adherence to this test method in all other respects will permit a better understanding and correlation between the results of different investigators. Active view current version of standard. It gives guidance on setting up a suitable apparatus and covers test and reporting procedures and precautions to be taken. Small differences between two materials are probably not significant, and their relative ranking could well be reversed in another test.

This must be considered in planning, conducting and reporting a test program.

An alternative method for similar purposes is Test Method Gwhich employs a cavitating liquid jet to produce erosion on a stationary specimen. It also specifies standard reference materials that must be used to verify the operation of the facility and to g2 the normalized erosion resistance of other test materials.

It permits deviations from some of these conditions if properly documented, that may be appropriate for some purposes.

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 zstm materials. The latter may be more suitable for materials not readily formed into a precisely shaped specimen. For specific safety warning information, see 6. However, adaptations of the basic method and apparatus have been used for such purposes asrm 9. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

The results of either, or anycavitation erosion test should be used with caution; see 5. 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.

The inch-pound units given in parentheses are for information only. In astmm method, the specimen is aastm within the liquid container, and the vibrating tip of the horn is placed in close proximity to it. Test Method G73 describes another testing approach specifically intended for that type of environment.

Guide G may be followed in order to determine the synergism between the mechanical and electrochemical effects.

Historical Version s – view previous versions of standard. While several investigators have used this approach see X4. This is because the compliance of the coating on the specimen may reduce the severity of the liquid cavitation induced by its vibratory motion.

For this reason, wstm consistency of results between axtm test methods or under different field conditions is not very good. The result would not be representative of a field application, where the hydrodynamic generation of cavitation is independent of the coating.

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.
