The American Society for Testing and Materials takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? Uneveness of surface may result from contact with fabric d33183, cutting techniques, or other reasons.
ASTM D e1. It is important that the wheel should run true, without vibration, and that the abrasive surface based on aluminum oxide or silicon carbide is true sstm sharp.
ASTM D3183 – 10(2015)
In operation the depth of cut should not exceed approximately 0. Such pieces are used as a source from which specimens are obtained for testing.
The grinder should be equipped with a slow-feed mechanism so that very light cuts may be made to avoid over-heating of the rubber.
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. Provision should be made for continuous sharpening of the cutting edge. If this is not possible, use commercial isooctane.
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. If a liquid is used, place the rubber so as to permit free evaporation of the liquid.
The sheets shall have one of the following thicknesses unless another thickness ashm technically necessary: Originally published as D — Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM Headquarters. In operation, cuts removing several tenths of a millimetre of rubber are practicable as the heat build up is much lower than with the method of 7.
Procedures are given for preparing pieces suitable for preparing specimens of the product. NOTE 2—Wheels of to mm 5 to 6-in.
Attachments are available for splitting and cutting sections from cable sheathing and hose.
Current edition approved March 30, Preparation of Pieces 7. The knife should be lubricated with a mild soap solution to ease the cutting operation. The machine consists of a motor- or hand-driven disk cutter of suitable diameter with a movable cutting table that transports the sample to the cutting edge.
NOTE 3—Grit sizes of 0.

Equipment should be provided for slow feeding of the material to the abrasive band and for securing the material without excessive deformation Note 3. Procedures in this section describe the preparation of pieces from vulcanizates that are too thick, have uneven surfaces, or contain textiles.
For removal of greater thicknesses of rubber, use the cutting techniques indicated in 7. The pieces shall be prepared in accordance with Section 7. Do not carry out buffing beyond the point where unevenness of thickness has been eliminated. A number in parentheses indicates the year of last reapproval. A superscript epsilon e indicates an editorial change since the last revision or reapproval.
Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. An adjustable slow-feed mechanism is? The abrasive bands should be of textile or paper, or a combination of the two, with the abradant based on aluminum oxide or silicon carbide bonded to its surface with a resin unaffected by water.
Clamping devices should be available to secure the rubber. Adjustments should be available to vary the thickness of cut, and feed rollers should be provided to transport the material past the knife.
ASTM D – 02 Standard Practice for Rubber—Preparation of Pieces for Test Purposes from Products
This standard has been approved for use by agencies of the Department of Defense. Take care to avoid excessive stretching of the rubber during the separation, by separating a little at a time while the rubber is gripped near the point of separation.
The buffing may be either against the drum, against one of the pulleys, or against the taut band between the pulleys. NOTE 1—For production quality control, testing within 1 to 6 h after vulcanization may be necessary to monitor plant operation.
Some skiving machines can separate plies of rubber as in belts, hose, and tires see 7. The successive cuts should be progressively thinner to avoid over-heating. Allow time for the complete evaporation of the liquid before the specimens x3183 cut and tested. Suitable means should be provided for securing the rubber to prevent excessive deformation and for controlled traversing of the rubber pass the abrasive wheel Note 2.
Last previous edition D — The sheets shall be vulcanized in accordance with Practice D and shall have an equivalent state of vulcanization judged from such properties as can be determined on the product.
