Remove the specimen s from the hot platens as quickly as possible after curing is completed, and cool the specimen at ambient temperature. The testing machine shall be equipped with astj autographic recorder rectilinear coordinates preferred and? As the voice of the U. Link to Active This link will always route to the current Active version of the standard.
A number in parentheses indicates the year of last reapproval. 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.
It is applicable to either woven or parallel cord textile structures from both natural and manmade fibers and to parallel steel cord structures. For steel cord, Test Method D provides convenient and rapid adhesion results. Combining values from the two systems may result in non-conformance with the standard. Separate straps are prepared for warp and across-warp direction except in special cases see 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.
Adhesion test compounds are usually replaced after six months; however, some may require replacement within a few weeks.
This test method provides a good comparison of variables on adhesion because it produces both an average numerical value of peel force over several linear centimetres of cord and provides convenient specimens for assessing appearance see 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.
Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. 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.

Note testing on CRT tester as a deviation, since separation rate and results will differ from those from a CRE tester. Read more about subscriptions.

Need more than one copy? Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. Subscription pricing is determined by: Consider shipping containers of cord and rolls of fabric to be the primary sampling units.
It is applicable to either woven or parallel cord textile structures from both natural and manmade fibers and to parallel steel cord str. Precision and Bias The more usual and convenient method for acceptance testing of such single 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.
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 tensile test machine. Since there is a characteristic peak in force at beginning of peel, ignore the?
The same basic test can be conveniently executed by the receiving customer for process control purposes by sampling rubberized fabric from that to be processed into? Formerly under the jurisdiction of Committee D13 on Textiles, this test method was withdrawn in February The inch-pound units in parentheses are provided in this test method are not necessarily exact equivalents of the SI units.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. If peel site was manipulated in the tensile test machine as directed in Remove holland cloth backing and place freshly-exposed surface against top of the? This system of adhesive treating facilitates the study of a large number of adhesion variables at minimum cost. Rubber moisture content less than 0.
It may be used for purchase speci? The recommended thickness gage of the skim stock varies from 0. Nevertheless, the expected range of values which characterize acceptable adhesion can be determined in any cord-rubber combination with experience. This standard is also available to be included in Standards Subscriptions.

The moment new editions d43933 the standards you monitor are released, changes are made, or appendixes are published, you will be alerted by email. Stay on Page Continue to Compass.
Exercise caution in sampling and handling so that samples receive minimum exposure to ambient atmosphere prior to rubber embedment. Set the recorder chart for approximately half the crosshead speed. Holland cloth or d44393 nonstick material should be used as the outside layer on either side of the? Add to Alert PDF.

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. It is applicable to either woven or parallel cord textile structures from both natural and manmade? Rubber compound differences are only one of many parameters affecting peel force and appearance.
Remove holland cloth backing and lay freshly-exposed surface up on a clean, nonstick surface. This standard is subject astmm revision at any time by the responsible technical committee and must be reviewed every? 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 awtm on the tensile test machine.
