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.
Asm reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm.
Rubber compound differences are only one of many parameters affecting peel force and appearance. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.
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.
It is applicable to either woven or parallel cord textile structures from both natural and manmade fibers and to parallel d44393 cord str. D — 04 appropriate for the cure rate of the rubber stock.
This standard is also available to be included in Standards Subscriptions. The moment new editions of the standards you monitor are released, changes are made, or appendixes are published, you will be alerted by email. 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 form of tire cord or fabric and one consistent rubber compound.
Link to Active This link will always route to the current Active version of the standard. It may be used for purchase speci? Precision and Bias D433 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.
Preparation of Weftless Fabric 8. Current edition approved Oct.
The 4 to 5-mm wider specimen in 9. Either system of units may be used in this test method. We have no amendments or corrections for this standard. Users of this standard are expressly advised that determination of the validity of any d44393 patent rights, and the risk of infringement of such rights, are entirely their own responsibility.
Straps are cut from the cured pad in its long direction parallel to the cords, and the force to peel one fabric layer from the other is determined in a recording zstm test machine. NOK 1 ,00 excl. Restart movement of the crosshead, and peel a sufficient portion to obtain a peel force reading. If a bias is found, either its cause must be found and corrected or the purchaser and the supplier must agree to interpret future test results in the light of the known bias.
This system of adhesive treating facilitates the study of a large number of adhesion variables at minimum cost.
Please first verify your email before subscribing to alerts. This test method covers the determination of peel adhesion of reinforcing fabrics that are bonded to rubber compounds.
Standards Subsctiption may be the perfect solution. Nevertheless, the expected range of values which characterize acceptable adhesion can be determined in any cord-rubber combination with experience. The more usual and d439 method for acceptance testing of such asym cords is to prepare from a shipment a test piece or article in the same manner as the commercial article to be produced and to test cord-adhesion characteristics in this piece in a manner that compares its adhesion characteristics against a previously established, acceptable control.
Subscription pricing is determined by: The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Holland cloth or other nonstick material should be used as the outside layer on either side of the?
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.
Remove the specimen from the hot mold as quickly as possible and air-cool the specimen. Add to Alert PDF. Proceed to peel this second rubber fabric interface.

Remove holland cloth backing and lay freshly-exposed surface up on a clean, nonstick surface. Originally published as D — Need more than one copy? Preparation of Pads and Specimens 9. Exercise caution in sampling and handling so that samples receive minimum exposure to ambient atmosphere prior to rubber embedment.
If peel site was astj in the tensile test machine as directed in For steel cord, Test Method D provides convenient and rapid adtm results.
