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 all cases the abrasive used is rounded quartz grain sand.
The feed rate is varied by adjusting the speed of the slotted drum. Need more than one copy?
The specimen arm may also include a strain gauge transducer to measure y105 dynamic friction. 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.
A touch—screen digital controller provides the user interface. Historical Version s – view previous versions of standard.
ASTM G105 – 16
Including precision abradant feed system astn peristaltic pump for alternative horizontal loading configuration. Already Subscribed to this document. Please first verify your email before subscribing to alerts. As the voice of the U. 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.

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 comparison will provide a general indication of the worth of the h105 materials if abrasion is the predominant factor causing deterioration of the materials. The machine is floor standing with test assemblies mounted on a back-plate and abradant discharged downwards into a hopper.
However it is restricted to one type of sand and there are no facilities for adjusting the mass flow over a wide range. We have no amendments or corrections for this standard. To provide analogue voltage friction force signal for data logger or chart recorder input. 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.
Including power supply and strain gauge amplifier. You may delete a document from your Alert Profile at any time. Load is applied by pneumatic bellows with a astn transducer for load measurement.
We have no document history for this standard. Test Configurations ASTM G 65 uses hopper fed sand through a defined nozzle aatm loads the test piece sideways on to the wheel. Link to Active This link will always route to the current Active version of the standard. This means that fully wet tests can be carried out, with the mass flow of abradant still controlled.
These define tests under dry or slurry conditions with specified loads, wheel speeds and sand feed g15. Excluding precision abradant feed system and peristaltic pump for alternative xstm loading configuration. It is the intent of this procedure to provide data that will reproducibly rank materials in their resistance to scratching abrasion under a specified set of conditions.
The wet rubber and steel wheel tests use a large volume of slurry containing 1. There is therefore considerable interest in the design, development and use of cost effective wear resistant materials for such applications. If the document is revised or amended, you will be notified by email.
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. The absolute wear rate and relative ranking of materials are greatly influenced by the following parameters: Please first log in with a verified email before subscribing to alerts.
