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. Adjustments should be available to vary the thickness of cut, and feed rollers should be provided to transport the material asfm the knife.
The knife should be lubricated with a mild soap solution to ease the cutting operation.

Equipment should be provided for r3183 feeding of the material to the abrasive band and for securing the material without excessive deformation Note 3. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. NOTE 3—Grit sizes of 0. This standard has been approved satm use by agencies of the Department of Defense.
If this is not possible, use commercial isooctane. 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.
Procedures are given for preparing pieces suitable for preparing specimens of the product. Preparation of Pieces 7. 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. A superscript epsilon e indicates an editorial change since the last revision or reapproval.
NOTE 1—For production quality control, testing within 1 to 6 h after vulcanization may be necessary to d3138 plant operation. Provision should be made for continuous sharpening zstm the cutting edge. Uneveness of surface may result from contact with fabric components, cutting techniques, or other reasons. In operation the depth of cut should d1383 exceed approximately 0. Procedures in this section describe the preparation of pieces from vulcanizates that are too thick, have uneven surfaces, or contain textiles.
It is important that the wheel should run true, without vibration, and that the abrasive surface based asmt aluminum oxide or silicon carbide is true and sharp. 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.
The sheets shall be vulcanized in accordance with Practice D and shall have an equivalent state of vulcanization judged from such properties as can d313 determined on the product. A number in parentheses indicates the year of last reapproval.
Clamping devices should be available to secure the rubber. 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.
The pieces shall be prepared in accordance with Section 7. Current edition approved March 30, Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM Headquarters. 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 2—Wheels of to mm 5 to 6-in. ASTM D e1.
ASTM D3183 – 10(2015)
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 — 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. An adjustable slow-feed mechanism is? Some skiving machines can separate plies of rubber as in belts, hose, and tires see 7.
Such pieces are used as a source from which specimens are obtained for testing. If a liquid is used, place the rubber so as to permit free evaporation of the liquid. Attachments are available for splitting and cutting sections from cable sheathing and hose. For removal of greater thicknesses of rubber, use the cutting techniques indicated in 7. The successive cuts should be progressively thinner to avoid over-heating.

Do not carry out buffing beyond the point where unevenness of thickness has been eliminated. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?
The buffing may be either against the drum, against one of the pulleys, or against the taut band between the pulleys.
