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.

In practice, abrasive materials will vary considerably in hardness, crushing strength and shape from the sand specified in the ASTM standards.
Materials of higher abrasion resistance will have a lower volume loss.
Both manually controlled and servo controlled pneumatic loading are available. 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. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
ASTM B uses a steel wheel, thus providing higher stress abrasion than the rubber wheel tests.

Already Subscribed to this document. The other asmt have a fluid trough and the slurry is agitated by the wheel rotation. Particle loading may be controlled over a wide range by adjusting the mass flow and the normal load on the test block.
Lower flow rates are desirable if non-standard abradants are to be used, thus requiring smaller batches to be produced. The feed rate is varied by adjusting the speed of the slotted drum.
The specimen arm may also include a strain gauge transducer to measure the dynamic friction. To provide analogue voltage friction force signal for data logger or chart recorder input. Including precision abradant feed system and peristaltic pump for alternative horizontal loading configuration.

The absolute wear rate and relative ranking of materials are greatly influenced by the following parameters:. The machine is floor standing with test assemblies mounted on a back-plate and abradant discharged downwards into a hopper. Excluding zstm abradant feed system and peristaltic pump for alternative horizontal loading configuration. Standards Subsctiption may be the perfect solution. G1105 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.
Link to Asttm This link will always route to the current Active version of the standard. Particle loading, the nominal load carried by each particle of abradant 2. It is clear, therefore, that a single set of test conditions will not be sufficient for determining the wear resistance of diverse materials.
ASTM G105 – 16
It would be preferable to be able to run with smaller samples or even to run multiple tests on one sample, thus reducing the cost per test.
Precision abradant feed system and peristaltic pump for alternative horizontal loading configuration. There is therefore a need for a reliable and convenient approach to the study of abrasive wear properties. 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 adtm a specific environment.
Rubber Wheel Sand Abrasion machine tests
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.
These define tests under dry or slurry conditions with specified loads, f105 speeds and sand feed rate.

The comparison will provide a general indication of the worth of the unknown materials if abrasion is the predominant factor causing deterioration of the materials. The values given in parentheses are for information only. 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. It is the intent of this procedure to provide data that will reproducibly rank materials aatm their resistance to scratching abrasion under a specified set of conditions.
By having control of the drum speed, much lower abradant mass flow rates can be achieved than in the ASTM G 65 method. Load is applied by pneumatic bellows with a force transducer for load measurement. We have no document history for this standard. The ASTM test pieces are relatively large and therefore expensive to prepare out of typical hard surfacing materials.
The consumption of sand is also high due qstm the large mass flow required.
