Wheel Apparatus has been involved with the ASTM Standardization Process for over 30 Optional Test Kits are available for either ASTM B or G testing. EPI Materials Testing group does custom wear testing and three standardized wear tests for their clients, ASTM G65, G, and B ASTM Methods ASTM G65 – 04 Standard Test Method for Measuring Abrasion Using the Dry Sand/Rubber Wheel Apparatus ASTM G – 02() Standard.

ASTM G 65 uses hopper fed sand through a defined nozzle and loads the test piece sideways on to the wheel. Link to Active This link will always route to the current Active version of the standard. Particle loading may be controlled over a wide range by adjusting the mass flow and the normal load on the test block. Abradant particle shape or angularity It is clear, therefore, that a single set of test conditions will not be sufficient for determining the wear resistance of diverse materials.
As the voice of the U. Ast, variable speed drive motor and ashm controlled pneumatic loading with precision regulator, force transducer and digital display.
Rubber Wheel Sand Abrasion machine tests
Abrasive wear of industrial materials handling plant e. It is the intent of this procedure to provide data that will reproducibly rank materials in their resistance to scratching abrasion under a specified set of conditions. It is clear, therefore, that a single set of test conditions will not be sufficient for determining the wear resistance of diverse materials.
Background Abrasive wear of industrial materials handling plant e. By having control of the drum speed, much lower abradant mass flow rates can be achieved than in the ASTM G 65 method.
Historical Version s – view previous versions of standard. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. Standards Subsctiption may be the perfect solution.
The ASTM test pieces are relatively large and therefore expensive to prepare out of typical hard surfacing materials. A number of standard methods have been developed with the aim of producing test data that will reproducibly rank materials under a specified set of conditions. Your Alert Profile lists the documents that will be monitored.
Lower flow rates are gg105 if non-standard abradants are to be used, thus requiring smaller batches to be produced. The consumption of sand is also high due to the large mass flow required.
The particle loading is a very crucial parameter for a given abradant as this controls whether the particle cuts or is crushed in the contact. Excluding precision abradant feed system and peristaltic pump for alternative horizontal loading configuration. We have no amendments or corrections for this standard. Add to Alert PDF.
ISO – Hardmetals — Abrasion tests for hardmetals
For wet tests, water is introduced on to the wheel surface, just behind the chute. Since the test method does not attempt to duplicate all of the process conditions abrasive size, shape, pressure, impact or corrosive elementsit should not be used to predict the exact resistance of a given material in a specific environment. The TE 65 is designed to perform tests according to the conditions described in the following methods:.
If the document is revised or amended, you will be notified by email.
This is not possible in the ASTM configuration. This standard is not included in any packages. In practice, abrasive materials will vary considerably in hardness, crushing strength and shape from the sand specified in the ASTM standards.
Already Subscribed to this document. However it is restricted to one type of sand and there are no facilities for adjusting the mass flow over a wide range.
There is therefore considerable interest satm the design, development and use of cost effective wear resistant materials for such applications.
Materials of higher abrasion resistance will have a lower volume loss. Need more than one copy? The feed rate is varied by adjusting the speed of the slotted drum.
Particle speed or cutting speed 4. Any abradant that does not v105 through the contact may be collected separately and therefore the quantity of abradant actually passing the test block may be determined. 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.
