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 this test method these conditions are standardized to develop a uniform condition of wear which has been referred to as scratching abrasion 1 and ashm.
Rubber Wheel Sand Abrasion machine tests
The TE 65 is designed to asmt tests according to the conditions described in the following methods:. The other standards have a fluid trough and the slurry is agitated by the wheel rotation.
Particle speed or cutting speed 4. With variable speed drive motor and manually controlled pneumatic loading with precision regulator, force transducer and digital display.
Lower flow rates are desirable if non-standard abradants are to be used, thus requiring smaller batches to be produced. Standards Subsctiption may be the perfect solution.
In all cases the abrasive used is rounded quartz grain sand. Download the Machine Leaflet.
ASTM G – 02 Standard Test Method for Conducting Wet Sand/Rubber Wheel Abrasion Tests
We have no amendments or corrections for this standard. Both manually controlled and servo controlled pneumatic loading are available.
Excluding precision abradant feed system and peristaltic pump for alternative horizontal loading configuration.
It ast, 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. Please first verify your email before subscribing to alerts. 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. Materials of higher abrasion resistance will have a lower volume loss.
The absolute wear rate and relative ranking of materials are greatly influenced by the following parameters:. A number of standard methods have been asttm with the aim of producing test data that will reproducibly rank materials under a specified set of conditions.
Subscription pricing is determined by: ASTM G 65 uses hopper fed sand through a defined nozzle and loads the test piece sideways on to the wheel. 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. As the voice of gg105 U. To provide analogue voltage friction force signal for data logger or chart recorder input.
Imbeni V Hutchings I. The abradant is fed from a hopper to a rotating drum with a shallow groove on its surface. Particle loading, the nominal load carried by each particle of abradant 2. However it is restricted to one type of sand and there are no facilities for adjusting zstm mass asym over a wide range. Precision abradant feed system and peristaltic pump for alternative gg105 loading configuration. 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 accessing standards. The consumption of sand is also high due to the large mass flow required.
Including power supply and strain gauge amplifier. The values given in parentheses are for information only.

The feed rate is varied by adjusting the speed of the slotted drum. In practice, abrasive materials will vary considerably in hardness, crushing strength and shape from the sand specified in g15 ASTM standards.
