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.

If the document is revised or amended, you will be notified by email. The out-fall from the drum is then guided to the b105 surface down a simple chute and this produces the monolayer on the wheel surface.
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. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of aastm limitations prior to use.
Particle loading, the nominal load carried by each particle of abradant 2. The values given in parentheses are for information only. Abrasive wear of industrial materials handling plant e. Particle loading may be controlled over a wide range by adjusting the mass flow and the normal load on the test block. Please first log in with a verified email before subscribing to alerts. Particle speed or cutting speed 4. The particle loading is a very crucial parameter for a given abradant as this asmt whether the particle cuts or is crushed in the contact.
You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server. Precision abradant feed system and peristaltic pump for alternative horizontal loading configuration.
Falex Tribology Testing and Technical Support
Any abradant that does not pass through the contact may be collected separately and therefore the quantity of abradant actually passing the test block may be determined. Both manually controlled and servo controlled pneumatic loading are available.
Test rollers not included. Add to Alert PDF.
Materials of higher abrasion resistance will have a lower volume loss. These define tests under dry or slurry conditions with specified loads, wheel speeds and sand feed rate.
A touch—screen digital controller provides the user interface. 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.
To provide analogue voltage friction force signal for asm logger or chart recorder input. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
This standard is also available to be included in Standards Subscriptions. Load is applied by pneumatic bellows with a force transducer for load measurement.
A number ast standard methods have been developed with the aim of producing test data that will reproducibly rank materials under a specified set of conditions.
With variable speed drive motor and manually controlled pneumatic loading with precision regulator, force transducer and digital display.
TE 65 MULTIPLEX SAND/WHEEL ABRASION TESTER
The consumption of sand is also high due to the large mass flow required. Background Abrasive wear of industrial materials handling plant e. This standard is not included in any packages. We have no amendments or sstm for this standard. Including precision abradant feed system and peristaltic pump for alternative horizontal loading configuration.
Test Configurations ASTM G 65 uses hopper fed sand through a defined nozzle and loads the test piece sideways on to the wheel. 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 of diverse materials.
By having control of the drum speed, much lower abradant mass flow rates can be achieved than in the ASTM G 65 method. In practice, abrasive materials will vary considerably in hardness, crushing strength and shape from the sand specified in the ASTM standards.
The abradant is fed from a hopper to a rotating drum with a shallow groove on its surface.
Rubber Wheel Sand Abrasion machine tests
The alternative abradant feed system is designed to give a range of constant feed rates and produce an even monolayer of f105 on the wheel in front of the contact. Abradant properties, namely hardness and crushing strength 6. In all cases the abrasive used is rounded quartz grain sand.
