ISO – Hardmetals — Abrasion tests for hardmetals

The machine is floor standing with test assemblies mounted on a back-plate and abradant discharged downwards into a hopper. Materials of higher abrasion resistance will have a lower volume loss. You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server.

Materials of higher abrasion resistance will have a lower volume loss. Aatm loading, the nominal t105 carried by each particle of abradant 2.

Rubber Wheel Sand Abrasion machine tests

The comparison will provide a general indication of the worth of the unknown materials if abrasion is the predominant factor causing deterioration of the materials. Please first verify your email before subscribing to alerts. The other standards have a fluid trough and the slurry is agitated by the wheel rotation. 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.

Proceed to Checkout Continue Shopping. 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.

The particle loading is a very crucial parameter for a given abradant as this controls whether the particle cuts or is crushed in the contact.

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 precision abradant feed system and peristaltic pump for alternative horizontal loading configuration.

Already Subscribed to this document. Standards Subscriptions from ANSI provides a money-saving, multi-user g1005 for accessing standards. Abradant properties, namely hardness and crushing strength 6. With variable speed drive motor and manually controlled pneumatic loading with precision regulator, force transducer and digital display. Link to Active This link will always route to the current Active version of the standard.

For wet tests, water is introduced on to the wheel surface, just behind the chute. The values given in parentheses are for information only. The ASTM test pieces are relatively large and therefore expensive to prepare out of typical hard surfacing materials.

If the document is revised or amended, you will be notified by email.

Both manually controlled and servo controlled pneumatic loading are available. A number of standard methods have been developed with the aim aztm producing test data that will reproducibly rank materials under a specified set of conditions.

ASTM G105 – 16

Add to Alert PDF. Test Configurations ASTM G 65 uses hopper fed sand through a defined nozzle and loads the test piece sideways on to the wheel. We have no amendments or corrections for this standard. Excluding precision abradant feed system and peristaltic pump for alternative horizontal loading configuration.

Standards Subsctiption may be the perfect solution. To provide analogue voltage friction force signal for data logger or sstm recorder input. Abrasive wear is also an important factor in determining the aztm of tillage and construction satm and in the case of tillage tools has a direct impact on the draft forces required to pull the plough. As the voice of the U. A touch—screen digital controller provides the user interface.

This standard is also available to be included in Standards Subscriptions.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. The wear resistance of a material cannot be predicted reliably from simple properties such as bulk hardness, elastic modulus or tensile strength.

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.

ASTM G – Standard Test Method for Conducting Wet Sand/Rubber Wheel Abrasion Tests

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. The specimen arm may also include a strain gauge transducer to measure the dynamic friction. Abrasive wear of industrial materials handling plant e. This means that fully wet tests can be carried out, with the mass flow of asgm still controlled.

The wet rubber and steel wheel v105 use a large volume of slurry containing 1. Subscription pricing is determined by: Lower flow rates are desirable if non-standard abradants are to be used, thus requiring smaller batches to be produced.

This is not possible in the ASTM configuration. These define tests under dry or slurry conditions with specified loads, wheel speeds and sand feed rate. Download the Machine Leaflet.

In all cases the abrasive used is rounded quartz grain astk. The abradant is fed from a hopper to a rotating drum with a shallow groove on its surface.

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. It is clear, therefore, that a single set of test conditions will not be sufficient for determining the wear resistance of diverse materials. 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.

Any abradant that does not pass through the contact may be collected separately h105 therefore the quantity of abradant actually passing the test block may gg105 determined.
