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.

TE 65 MULTIPLEX SAND/WHEEL ABRASION TESTER
Already Subscribed v105 this document. For wet tests, water is introduced on to the wheel surface, just behind the chute. ASTM B uses a steel wheel, thus providing higher stress abrasion than the rubber wheel tests. Smaller quantities are desirable if non-standard abradants are to be used. The absolute wear rate and relative ranking of materials are greatly influenced by the following parameters:. Download the Machine Leaflet.

The ASTM test pieces are relatively large and therefore expensive to prepare out of axtm hard surfacing materials. The abradant aastm fed from a hopper to a rotating drum with a shallow groove on its surface.
ASTM G 65 uses hopper fed sand through a defined nozzle and loads the test piece sideways on to the wheel. 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.
ASTM G – Standard Test Method for Conducting Wet Sand/Rubber Wheel Abrasion Tests
Link to Active This link will always route to the current Active version of the standard. There is therefore considerable interest in the design, development and use of cost effective wear resistant materials for such applications. The TE 65 is designed to perform tests according to the conditions described in the following methods:.
Subscription pricing is determined by: Background Abrasive wear of industrial materials handling plant e. Materials of higher abrasion resistance will have a lower volume loss.
Need more than one copy? The specimen arm may also include a strain gauge transducer to measure the dynamic friction. The values given in parentheses are for information only.
Abrasive wear of industrial materials handling plant e. The consumption of sand is also high due to the large mass flow required. In practice, abrasive materials asttm 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 astj monolayer of particles on the wheel in front of the contact. If the document is revised or amended, you will be notified by email.

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. Proceed to Checkout Continue Shopping. The absolute wear rate and relative ranking of materials are greatly influenced by the following parameters: It is clear, therefore, that a single set of test conditions will not be sufficient for determining the wear resistance of diverse materials.
This is not possible in the ASTM configuration. Test Configurations ASTM G 65 uses hopper fed sand through aastm defined nozzle and loads the test piece sideways on to the wheel. In all cases the abrasive used is rounded quartz grain sand. 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.
Including precision abradant feed system and peristaltic ast for alternative horizontal loading configuration. Imbeni V Hutchings I. 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. Load is applied by pneumatic bellows with a force transducer for load measurement. Test rollers not included. This means that fully wet tests can be carried out, with the mass flow of abradant still controlled.
Standards Subsctiption may be the perfect solution. 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 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. Both manually controlled and servo controlled pneumatic loading are available. Particle speed or cutting speed 4. The other astmm have a fluid trough and the slurry is agitated by the wheel rotation. It is the intent of this procedure to provide data that will reproducibly rank asmt in their resistance to scratching abrasion under a specified set of conditions.
Your G1055 Profile lists the documents that will be monitored. 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. This standard is not included in any packages.
