Need more than one copy? This system of adhesive treating facilitates the study of a large number of adhesion variables at minimum cost. Summary of Test Method 4. 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.
Your Alert Profile lists the documents that will be monitored. Describe the products sampled and the method of sampling used.
Subscription – always available and updated A web subscription provides an easy and secure access to standards, and you are guaranteed to always have the latest edition. Apparatus and Materials 6.
Set the recorder chart for approximately half the crosshead speed. It is applicable to either woven or parallel cord textile structures from both natural and manmade fibers and to parallel steel cord structures. Note testing on CRT tester as a deviation, since separation rate and results will differ from those from a CRE tester.
For steel cord, it may be required to use a backing fabric in place of atsm additional rubber or portion thereof in order to maintain integrity of the specimen during peeling on the tensile test machine. 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.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. The test specimens should then be randomly assigned in equal numbers to each laboratory for testing.
Remove the specimen s from the hot platens as quickly as possible after curing is completed, and cool the specimen at ambient temperature. Adhesion test compounds are usually replaced after six months; however, some may require replacement within a few weeks. Since there is a characteristic peak in force at beginning of peel, ignore the?
It is the responsibility of the user of this standard to establish appropriate safety d44393 health practices and determine the applicability of regulatory limitations prior to use. The 4 to 5-mm wider specimen in 9. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. It is applicable to either woven or parallel cord textile structures from both natural and manmade fibers and to parallel steel cord str. NOK 1 ,00 excl. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.
The same basic test can be conveniently executed by the receiving d433 for process control purposes by sampling rubberized fabric from that to be processed into?
Exercise caution in sampling and handling so that samples receive minimum exposure to ambient atmosphere prior to rubber embedment. These pieces are assembled on a clean? This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?
Separate straps are prepared for warp and across-warp direction except in special cases see 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 Combining values from the two systems may result in non-conformance with the standard.
Current edition approved Oct. These two fabrics are laid one against the other, with cords in the same direction, to form the pad Fig. If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below. Determine adhesion force by one of the options in Last previous edition D — This standard is also available to be included in Standards Subscriptions.
This ensures that you are always up-to-date and saves you both time and money. A web subscription provides an easy and secure access to standards, and you are guaranteed to always have the latest edition.
The force to peel one fabric layer from the other is determined in a recording tensile testing machine. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.
This test method may be used to evaluate tire cord adhesives fabric dipmetallic usually brass coatings on xstm cord, and the process of adhesive reaction on the cord using one consistent form of tire cord or fabric and one consistent rubber compound. The long dimension of this fabric is in the warp direction.

As the voice of the U. This pad has a nonstick fabric, such as holland cloth, separating the two satm layers at one end for a sufficient distance to eventually permit adjacent ends of each 4 For referenced ASTM standards, e4393 the ASTM website, www. 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.
Remove the specimen from the hot mold as qstm 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.
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: Or, if tensile testing machine has such capability, average separation force may ast, read directly from the instrument display.
A number in parentheses indicates the year of last reapproval. It is applicable to either woven or parallel cord textile structures from both natural and manmade fibers and to parallel steel cord structures. Remove holland cloth backing and lay freshly-exposed surface up on a clean, nonstick surface.
