However, adherence to this test method in all other respects will permit a better understanding and correlation between the results of different investigators. It gives guidance on setting up a suitable apparatus and covers test and reporting procedures and precautions to be taken. It asstm deviations from some of these conditions if properly documented, that may be appropriate for some purposes. While several investigators have used this approach see X4.

Link to Active This link will always route to the current Active version of the standard. 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. 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.

However, adaptations of the basic method and apparatus have been atsm for such purposes see 9. An alternative method for similar purposes is Test Method Gwhich employs a cavitating liquid jet to produce erosion on a stationary specimen. Link to Active This link will always route to the current Active version of the standard. This must be considered in planning, conducting and reporting a test program.

The inch-pound units given in parentheses are for information only. This is because the compliance of the coating on the specimen may reduce the severity of the liquid cavitation induced by its vibratory motion.

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

Test Method G73 describes another testing approach specifically intended for that type of environment. The result would not be representative of a field application, where the aatm generation of cavitation is independent of the coating.

The results of either, or anyg23 erosion test should be used with caution; see 5. 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. Guide G may be followed in order to determine the synergism between the mechanical and electrochemical effects.

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. Historical Version s – view previous versions of standard. 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. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

For this reason, the consistency of results between different test methods or under different zstm conditions is not very good. 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.

ASTM G32 – 16 Standard Test Method for Cavitation Erosion Using Vibratory Apparatus

The latter may be more suitable for materials not readily formed into a precisely shaped specimen. 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 axtm, as required for this test method see 7.

For specific astn warning information, see 6. It gives guidance on setting up a suitable apparatus and covers test and reporting procedures and precautions to be taken.

Erosion Testing

Active view current ast of standard. 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.

Small differences between two materials are probably not significant, and adtm relative ranking could well be reversed in another test. For aatm safety warning information, see 6. 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.
