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.

ASTM G105 – 16
This is not possible in the ASTM configuration. Need more than one copy? The TE 65 includes the option of a second loading position that presses the specimen on to the top of the wheel, with g015 specimen horizontal.
Subscription ashm is determined by: The absolute wear rate and relative ranking of materials are aetm influenced by the following parameters: ASTM B uses a steel wheel, thus providing higher stress abrasion than the rubber wheel tests.
Download the Machine Leaflet. If the document is revised or amended, you will be notified by email. The abradant is fed from a hopper to a rotating drum with a shallow groove on its surface. The specimen arm may also include a strain gauge transducer to measure the dynamic friction. With variable speed drive motor and manually controlled pneumatic loading with precision regulator, force transducer and digital display. With variable speed drive motor, servo controlled pneumatic loading with force transducer feedback, friction force transducer, displacement transducer.
You can download and open this file to your own computer but DRM prevents opening this file on another g1005, including a networked server.
It is the responsibility of aastm user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Please first verify your email before subscribing to alerts. Link to Active This link will always route to the current Active version of the standard.
The values given in parentheses are for information only. 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. To provide analogue voltage friction force signal for data logger or chart recorder input. 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.
TE 65 MULTIPLEX SAND/WHEEL ABRASION TESTER
Lower flow rates are desirable if non-standard abradants are to be used, thus requiring smaller batches to be produced. There is therefore a need for a reliable and convenient approach to the study of abrasive wear properties.
Historical Version s – view previous versions of standard. Materials of higher abrasion resistance will have a lower volume loss. We have no document history for this standard. Both manually controlled and servo controlled pneumatic loading are available. This standard is not included in any packages. 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.
Including precision abradant feed system and peristaltic pump for alternative horizontal loading configuration. We have no amendments or corrections for this standard.
ASTM G – 16 Standard Test Method for Conducting Wet Sand/Rubber Wheel Abrasion Tests
Test rollers not included. 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 zstm in predicting the ranking of materials in a similar relative order of merit as would occur in an abrasive environment. Precision abradant feed system and peristaltic pump for alternative horizontal loading configuration. Already Subscribed to this document. Particle speed or cutting speed 4. You may delete a document from your Alert Profile at any time.
By having control of the drum speed, much lower abradant mass flow rates can be achieved than g15 the ASTM G 65 method. 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.
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. There is therefore considerable interest in the design, development and use of cost effective wear resistant materials for such applications. Standards Subscriptions from ANSI provides wstm money-saving, multi-user solution for accessing standards.
It is clear, therefore, that a single set of test conditions will not be sufficient for determining the wear resistance of diverse materials. The feed rate is varied by adjusting the speed of the slotted drum. For wet tests, water is introduced on to the wheel surface, just behind the chute.
Load is applied by pneumatic bellows with a force transducer for load measurement. Add to Alert PDF. It is the responsibility of the user of this standard to establish appropriate safety and health practices f105 determine the applicability of regulatory limitations prior to use. 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.
The consumption of sand is also high due to the large mass flow required. The ASTM test pieces are relatively large and therefore expensive to prepare out of typical hard surfacing materials.
