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.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. By having control of the drum speed, much lower abradant mass flow rates can be achieved than in the ASTM G h105 method. Please first log in with a verified email before subscribing to alerts. The Asrm 65 is designed to perform tests according to the conditions described in the following methods: Materials of higher abrasion resistance will have a lower volume loss.
The other standards have a fluid trough and astn slurry is agitated by the wheel rotation. Subscription pricing is determined by: The absolute wear rate and relative ranking of materials are greatly influenced by the following parameters: The ASTM test pieces are relatively large and therefore expensive to prepare out of typical hard surfacing materials. Abradant properties, namely hardness and crushing strength 6.
Both manually controlled and servo controlled pneumatic loading are available. The machine is floor standing with test assemblies mounted on a back-plate and abradant discharged downwards into a hopper. Smaller quantities are desirable if non-standard abradants are to be used. The feed rate is varied by adjusting the speed of the slotted drum.
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. 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.
This standard is also available to be included in Standards Subscriptions.
We have no amendments or corrections for this standard. Proceed to Checkout Continue Shopping. Particle loading may be controlled over a wide range by adjusting the mass flow and the normal load on the test block.
TE 65 MULTIPLEX SAND/WHEEL ABRASION TESTER
The wet rubber and steel wheel tests use a large volume of slurry containing 1. 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.
G15 provide analogue voltage friction force signal for data logger or chart recorder input. There is therefore considerable interest in the design, development and use of cost effective wear resistant materials for such applications.
A touch—screen digital controller provides the user interface. Materials of higher abrasion resistance will have a lower volume loss. It is clear, therefore, that a single set of test conditions will atsm be sufficient sstm determining the wear resistance of diverse materials. Precision abradant feed system and peristaltic pump for alternative horizontal loading configuration.
Lower flow rates are desirable if non-standard abradants are to be used, thus requiring smaller batches to be produced. The abradant is fed from a hopper to a rotating drum with a shallow groove on its surface.
Particle speed or cutting speed 4. It is the intent of this procedure to provide data that will reproducibly rank asm in g05 resistance to scratching abrasion under a specified set of conditions. This standard is not included in any packages.
In practice, abrasive materials will vary considerably in hardness, crushing strength and shape from the sand specified in the ASTM standards. ASTM B uses a steel wheel, thus providing higher stress abrasion than the rubber wheel tests. Abrasive wear is also an important factor in determining the life of tillage and construction equipment and in the case xstm tillage tools has a direct impact on the draft forces required to pull the plough.
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. Historical Version s – view previous versions of standard. In this test method these conditions are standardized to develop a uniform condition of wear which has been referred to as scratching abrasion ast, and 2.

Load is applied by pneumatic bellows with a force transducer for load measurement. The values given in parentheses are for information only. With variable speed drive motor and manually controlled pneumatic loading with precision regulator, force transducer and digital display.
ASTM G – 16 – Standard Test Method for Conducting Wet Sand/Rubber Wheel Abrasion Tests
Please first verify your email before subscribing to alerts. Particle loading, the nominal load carried by each particle of abradant 2. Standards Subsctiption may be the perfect solution.
