For removal of greater thicknesses of rubber, use the cutting techniques indicated in 7. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?

ASTM D3183 – 10(2015)

Allow time for the complete evaporation of the liquid before the specimens are cut and tested. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM Headquarters.

Some skiving machines can separate plies of rubber as in belts, hose, and tires see 7. The pieces shall be prepared in accordance with Section 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.

The sheets shall have one of the following thicknesses unless another thickness is technically necessary: NOTE 3—Grit sizes of 0. ASTM D e1.

Clamping devices should be available to secure the rubber. 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. Uneveness of surface may result from contact with fabric components, cutting techniques, or other reasons. The successive cuts should be progressively thinner to avoid over-heating. 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.

NOTE 2—Wheels of to mm 5 to 6-in. Preparation of Pieces 7. Users of this standard are expressly advised that determination of the validity of any such patent rights, and aetm risk of infringement of such rights, are entirely their own responsibility. Procedures in this section describe the preparation of pieces from vulcanizates that are too thick, have uneven surfaces, or contain textiles.

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 d183 7.

ASTM D – 02 Standard Practice for Rubber—Preparation of Pieces for Test Purposes from Products

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. Procedures are given for preparing pieces suitable for preparing specimens of the product. The machine consists of a motor- or hand-driven disk cutter of suitable diameter with a movable cutting table that transports the sample to r3183 cutting edge.

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. Equipment should be provided for slow feeding of the material to the abrasive band and for securing d3138 material without excessive deformation Note 3. Do not carry out buffing beyond the point where unevenness of thickness has been eliminated.

Originally published as D — The knife should be lubricated with a mild soap solution to ease the cutting operation.

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. This standard zstm been approved for use by agencies of the Department of Defense.

Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. 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. Adjustments should be available to vary the thickness asttm cut, and feed rollers should be provided to transport the material past the knife. Current edition approved March 30, A number in parentheses indicates the year of last reapproval.

Attachments are available for splitting and cutting sections from cable sheathing and hose. An adjustable slow-feed r3183 is? 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.
