Last previous edition D — Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. Some skiving machines can separate plies of rubber as in belts, hose, and tires see 7.
Current edition approved March 30, 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. Such pieces are used as a d3138 from which specimens are obtained for testing. An adjustable slow-feed mechanism is? Clamping devices should be available to secure the rubber.
This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? If a liquid is used, place the rubber so as to permit free evaporation of the liquid. In operation the depth of cut should not exceed approximately 0.
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.
The successive cuts should be progressively thinner to avoid over-heating. Attachments are available for splitting and cutting sections from cable sheathing and hose. NOTE 1—For production quality control, testing within 1 to 6 h after vulcanization may be necessary to monitor plant operation.
Preparation of Pieces 7.
ASTM D3183 – 10(2015)
Allow time for the complete evaporation of the liquid before the specimens are cut asmt tested. Uneveness of surface may result from contact with fabric components, cutting techniques, or other reasons.
The knife should be lubricated with a mild soap solution to ease the cutting operation. Provision should be made for continuous sharpening of the cutting edge. 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.

Do not carry out buffing beyond the point where unevenness of thickness has been eliminated. NOTE 2—Wheels of to mm 5 to 6-in. Your comments are invited either for revision of this standard f3183 for additional standards and should be addressed to ASTM Headquarters. 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.
Suitable means should be provided for securing the rubber to prevent excessive deformation and for controlled traversing of f3183 rubber pass the abrasive wheel Note 2.
Originally published as D — asym NOTE 3—Grit sizes of 0. The sheets shall have one of the following thicknesses unless another thickness is technically necessary: Procedures are given for preparing pieces suitable for preparing specimens of the product.
A superscript epsilon e indicates an editorial change since the last revision or reapproval. 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.
ASTM D e1. 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. This standard has been approved for use by agencies of the Department of Defense.
If this is not possible, use commercial isooctane. Adjustments should be available to vary the thickness of cut, and feed rollers should be provided to transport the material past the knife. For removal of greater thicknesses of rubber, use the cutting techniques indicated in 7.
The pieces shall be prepared in accordance with Section 7.
