Start Webshop Product catalog Product qstm. You may delete a document from your Alert Profile at any time. Remove the specimen from the hot mold as quickly as possible and air-cool the specimen. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Exercise caution in sampling and handling so that samples receive minimum exposure to ambient atmosphere prior to rubber embedment. You need to log in before adding standards to the monitoring service. The recommended thickness gage of the skim stock varies from 0.
Material Test Machines and Equipment
Set the recorder chart for approximately half the crosshead speed. Restart movement of the crosshead, and peel a sufficient portion to obtain a peel force reading.
Remove the specimen s from the hot platens as quickly as possible after curing is completed, and cool the specimen at ambient temperature.
Peel force in Section 11 shall be calculated separately for each face. A number in parentheses indicates the year of last reapproval. Holland cloth or other nonstick material should be used as the outside layer on either side of the? With the specimen in the jaws of the tensile testing machine and under a tension less than that required to peel the specimen, stop the crosshead and cut through the rubber separating the two fabric layers to the surface of one of the fabric layers.
This test method may be used to evaluate cords and fabrics in industrial hose and belting products and other cord or fabric reinforced rubber products. In place of the additional rubber or as a part thereof on the outer sides of the primary fabric-rubber-fabric sandwich, place on the following: Rubber moisture content less than 0. Stop the crosshead and cut through the rubber to the opposite fabric face. Link to Active This link will always route to the current Active version of the standard.
This pad has a nonstick fabric, such as holland cloth, separating the two fabric layers at one end for a sufficient distance to eventually permit adjacent ends of each 4 For referenced ASTM standards, visit the ASTM website, www.
Remove holland cloth backing and lay freshly-exposed surface up on a clean, nonstick surface. The testing machine shall be equipped with an autographic recorder rectilinear coordinates preferred and?
This test method covers the determination of peel adhesion of reinforcing fabrics that are bonded to rubber compounds. This test method may be used to evaluate tire cord adhesives fabric dipmetallic usually brass coatings on steel cord, and the process of adhesive reaction on the cord using one consistent aetm of tire cord or fabric and one consistent rubber compound.

Combining values from the two systems may result in non-conformance with the standard. This standard is subject to revision at any time by the responsible technical ashm and must be reviewed every?
This standard is not included in any packages. The values stated in each system may not be exact equivalents; therefore, each system shall be used d43393 of the other.
A superscript epsilon e indicates an editorial change since the last revision or reapproval.
The same basic test can be s4393 executed by the receiving customer for process control purposes by sampling rubberized fabric from that to be processed into? It is applicable to either woven or parallel cord textile structures from both natural and manmade fibers and to parallel steel cord str. If you need to be able to add standards to the monitoring service, you must register as a user with your own username and password.
For steel cord, it may be required to use a backing fabric in place of the additional rubber or portion thereof in order to maintain integrity of the specimen during peeling on the tensile test machine.
This test method may be used to evaluate cords and fabrics in industrial hose and belting products and other cord or fabric reinforced rubber products.
These pieces are assembled on a clean? This test method covers the asmt of peel adhesion of reinforcing fabrics that are bonded to rubber compounds. Or, if tensile testing machine has such capability, average separation force may be read directly from the instrument display.
This service is not available if you are a URL user where you do not log in with an email address. Consider shipping containers of cord and rolls of fabric to be the primary sampling units. Last previous edition D — Monitoring Standards monitoring is a free service designed for you who wish to be alerted of changes to or new editions of the standards required in your work. Subscription – always available and updated A web subscription provides an easy and secure access to standards, and you d493 guaranteed to always have the latest edition.
If peel site was manipulated in the tensile test machine as directed in Rubber compound differences are only one of many parameters affecting peel force and appearance. Apparatus and Materials 6. The inch-pound units in parentheses are provided in this test method are not necessarily exact equivalents of the SI units.
Link to Active This link will always route to the current Active version of the standard. The test specimens should then be randomly assigned in equal numbers to each laboratory for testing.
Aastm web subscription provides an easy ast, secure access to standards, and you are guaranteed to always have the latest edition. Nevertheless, the expected range of values which characterize acceptable adhesion can be determined in any cord-rubber combination with experience.
It may be used for purchase speci?
Summary of Test Method 4. Current edition approved Oct. In a multi-item pad, orientation of the two weftless fabric pieces must be maintained so that individual cord items to be tested face each other in the? Competent statistical help is recommended for the investigation of bias.
