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 value of the test method lies in predicting the ranking of materials in a similar relative order of merit as would occur in an abrasive environment. The wear resistance of a material cannot be predicted reliably from simple properties such as bulk hardness, elastic modulus or tensile strength.

Both manually controlled and servo controlled pneumatic loading are available. The ASTM test pieces are relatively large and therefore expensive to prepare out of typical hard surfacing materials. You may delete a document from your Alert Profile at any time. In practice, abrasive materials will vary considerably in hardness, crushing strength and shape from the sand specified in the ASTM standards.

The absolute wear rate and relative ranking of materials are greatly influenced by the following parameters: Imbeni V Hutchings I. The feed rate is varied by adjusting the speed of the slotted drum. Load is applied by pneumatic bellows with a force transducer for load measurement.

ASTM G105 – 16

By having control of the drum speed, much lower abradant mass flow rates can be achieved than in the ASTM G 65 method. Test Configurations ASTM G 65 uses hopper fed sand through a defined nozzle and loads the test piece sideways on to the wheel. Proceed to Checkout Continue Shopping. Volume loss data obtained from test materials whose lives are unknown in a specific abrasive environment may, however, be compared with test data obtained from a material whose life is known in the same environment.

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.

We have no document history for this standard. Historical Version s – view previous versions of standard. A touch—screen digital controller provides the user interface. The alternative abradant feed system is designed to give a range of constant feed rates and produce an even monolayer of particles on the wheel in front of the contact.

There is therefore considerable interest in the design, development and use of cost effective wear resistant materials for such applications. In all cases the abrasive used is rounded quartz grain sand. Please first log in with a verified email before subscribing to alerts. Including precision abradant feed system and peristaltic pump for alternative horizontal loading configuration.

Background Abrasive wear of industrial materials handling plant e. Precision abradant feed system and peristaltic pump for alternative horizontal loading configuration. This standard is not included in any packages. The abradant is fed from a hopper to a rotating drum with a shallow groove on its surface. Abradant properties, namely hardness and crushing strength 6. The values given in parentheses are for information only. 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.

ASTM G – 02 Standard Test Method for Conducting Wet Sand/Rubber Wheel Abrasion Tests

We have no amendments or corrections for this standard. Download the Machine Leaflet. ASTM G 65 uses hopper fed sand through a defined nozzle and loads the test piece sideways on to the wheel. 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, gg105 speeds and sand feed rate.

Any abradant that does not pass through the contact may be collected separately and therefore the quantity of zstm actually passing the test block may be determined.

With variable speed drive motor, servo controlled pneumatic loading with force transducer feedback, friction force transducer, displacement transducer.

There is therefore a need for a reliable and convenient approach to the study of abrasive aztm properties. The values given in parentheses ast for information only. For wet tests, water is introduced on to the wheel surface, just behind the chute. 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. In this test method these conditions are standardized to develop a uniform condition of wear which astj been referred to as scratching abrasion 1 and 2.

Since the test method does not attempt to duplicate all of the process conditions abrasive size, shape, pressure, impact or corrosive elementsit should sstm be used to predict the exact resistance of a given material in a specific environment.

Already Subscribed asym this document. 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.

It is clear, therefore, that a single set of test conditions will not be sufficient for determining the wear resistance of diverse materials. 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 to scratching abrasion under a specified set of conditions.
