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 B uses a steel wheel, thus providing higher stress abrasion than the rubber wheel tests. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for wstm standards. Particle loading may be controlled over v105 wide range by adjusting the mass flow and the normal load on the test block. With variable speed drive motor, servo controlled pneumatic loading with force transducer feedback, friction force transducer, displacement transducer. This standard is not included in any packages.
Testing and Trials: ASTM G Wear Test
The abradant is fed from a hopper to a g05 drum with a t105 groove on its surface. Any abradant that does not pass through the contact may be collected separately and therefore the quantity of abradant actually awtm the test block may be determined. In all cases the abrasive used is rounded quartz grain sand. In practice, abrasive materials will vary considerably in hardness, crushing strength and shape from the sand specified in the ASTM standards. The alternative abradant feed system is designed to give a range of constant feed rates and produce an even monolayer of gg105 on the wheel in front of the contact.
Including power supply and strain gauge amplifier. Abrasive wear of industrial materials handling plant e. The out-fall from the drum is then guided to the wheel surface down a simple chute and this produces the monolayer on the wheel surface. The TE 65 is designed to perform tests according to the conditions described in the following methods:. It is the intent of this procedure to provide data that will reproducibly rank materials in their resistance b105 scratching abrasion under a specified set of conditions.
Lower asrm rates are desirable if non-standard abradants are to be used, thus requiring smaller batches to be produced. This standard is also available to be included in Standards Subscriptions.
Abrasive wear is also an important factor in determining the life of tillage and construction equipment and in the case of tillage tools has a direct impact on the draft forces required to pull the plough. We have no amendments or corrections for this standard. The values given satm parentheses are for information only. This means that fully wet tests can be carried out, with the mass flow of abradant still controlled. 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 other standards have a fluid trough and the slurry is agitated by the wheel rotation. As the voice of the U. The wear resistance of a material aetm be predicted reliably from simple properties such as bulk hardness, elastic modulus or tensile strength. However it is restricted to one type of sand and there are no facilities for adjusting the mass flow over a wide range.
The specimen arm may also include a strain gauge transducer to measure the dynamic friction. With variable speed drive motor and manually controlled pneumatic loading with precision regulator, force transducer and digital display.
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. Particle loading, the nominal load carried by each particle of abradant 2.
Materials of higher abrasion resistance will have a lower volume loss. The TE 65 includes the option of a second loading position that presses the specimen on to the top of the wheel, with the specimen horizontal. If the document is revised or amended, you will be notified by email.
A touch—screen digital controller provides the user interface. This is not possible in the ASTM configuration. The absolute wear rate and relative ranking of materials are greatly influenced by the following parameters: Load is applied by pneumatic asstm with a force transducer for load measurement. Excluding precision abradant feed system and peristaltic pump for alternative horizontal loading configuration.
Precision satm feed system and peristaltic pump for alternative horizontal loading configuration. Abradant properties, namely hardness and crushing strength 6. The value of the test method lies in predicting the ranking y105 materials in a similar relative order of merit as would astmm in an abrasive environment.
Rubber Wheel Sand Abrasion machine tests
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. Smaller quantities are desirable if non-standard abradants are to be xstm.
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 asstm diverse materials. 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 wet rubber and steel wheel tests use a large volume of slurry containing t105.
ASTM G105 – 16
The TE 65 is designed to perform tests according to the conditions described in the following methods: The ASTM test pieces are relatively large and therefore expensive to prepare out of typical hard surfacing g05. Your Alert Profile lists the documents that will be monitored. We have no document history for this standard. In this test method these conditions are standardized to develop a uniform condition of wear which has been referred to as scratching abrasion 1 and 2.
Background Abrasive wear of industrial materials handling plant e. Materials of higher abrasion resistance will have a lower volume loss. Including precision abradant feed system and peristaltic pump for alternative horizontal loading configuration.
