An adjustable slow-feed mechanism is? 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. Some skiving machines can separate plies of rubber as in belts, hose, and tires see 7.
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 d318 a resin unaffected by water.
ASTM D3183 – 10(2015)
Suitable means should be provided for securing the rubber to prevent ast deformation and for controlled traversing of the rubber pass the abrasive wheel Note 2. 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.
ASTM D e1. Allow time for the complete evaporation of the liquid before the specimens are cut and tested.
Uneveness of surface may result from contact with fabric components, cutting techniques, or other reasons. Procedures are given for preparing pieces suitable for preparing specimens of the product.
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.
This standard has been approved for use by agencies of the Department of Defense. Clamping devices should be available to secure the rubber. Attachments are available for splitting and cutting sections from cable sheathing and hose. In operation the depth of cut should not exceed approximately 0.
Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. Originally published as D — Provision should be made for continuous sharpening of the cutting edge.
Equipment should be provided for slow feeding of the material to the abrasive band and for securing the material without excessive deformation Note 3. The knife should be lubricated with a mild soap solution to ease the cutting operation.

For removal of greater thicknesses of astmm, use the cutting techniques indicated in 7. If this is not possible, use commercial isooctane. Do not carry out buffing beyond the point where unevenness of thickness has been eliminated. A superscript epsilon e indicates an editorial change since the last revision or reapproval.
NOTE 2—Wheels of to mm 5 to 6-in. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of asm of such rights, are entirely their own responsibility.
ASTM D – 02 Standard Practice for Rubber—Preparation of Pieces for Test Purposes from Products
Such pieces are used as a source from which specimens are obtained for testing. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? 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.
Last previous edition D — The sheets shall have one of the following thicknesses unless another thickness is technically necessary: NOTE 3—Grit sizes of 0. NOTE 1—For production quality control, testing within 1 to 6 h after vulcanization may be necessary to monitor plant operation. The pieces shall be prepared in accordance with Section 7. 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.
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.
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. 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 and sharp. The successive cuts should be progressively thinner to avoid over-heating.
Adjustments should be available to vary the thickness of cut, and feed rollers should be provided to transport the material past the knife. Procedures in this section describe the preparation of pieces from vulcanizates that are too thick, have uneven surfaces, or contain textiles. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM Headquarters. Preparation of Pieces 7. The buffing may be either against the drum, against one of the pulleys, or against the taut band between the pulleys.
A number in parentheses indicates the year of last reapproval. If a liquid is used, place the rubber so as to permit free evaporation of the liquid.
