ASTM D3183 – 10(2015)

Preparation of Pieces 7. Procedures are given for preparing pieces suitable for preparing specimens of the product. 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. In operation the depth of cut should not exceed approximately 0. This standard has been approved for use by agencies of the Department of Defense. 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.

NOTE 3—Grit sizes of 0. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM Headquarters. If a liquid is used, place the rubber so as to permit free evaporation of the liquid. Current edition approved March 30, Adjustments should be available to vary the thickness of cut, and feed rollers should be provided to transport the material past the knife.

Allow time for the complete evaporation of the liquid before the specimens are cut and tested. A number in parentheses indicates the year of last reapproval. Uneveness of surface may result from contact with fabric components, cutting techniques, or other reasons.

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. 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. Provision should be made for continuous sharpening of the cutting edge. Clamping devices should be available to secure the rubber.

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.

If this is not possible, use commercial isooctane. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. 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 have one of the following thicknesses unless another thickness is technically d183 Do not carry out buffing beyond the point where unevenness of thickness has been eliminated.

An adjustable slow-feed mechanism is? For removal of greater thicknesses of rubber, use the cutting techniques indicated in 7.

The buffing may be either against the drum, against one of the pulleys, or against the taut band between the pulleys.

Equipment should be provided for slow feeding of the material to the abrasive band and for securing the material without excessive deformation Note 3. This standard is subject to revision at any time by astn responsible technical committee and must be reviewed every?

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

A superscript epsilon e indicates an editorial change since the last revision or reapproval.

The grinder should be equipped with a slow-feed mechanism so that very sstm cuts may be made to avoid over-heating of the rubber. Such pieces are used as a source from which specimens are obtained for testing.

ASTM D e1. Procedures in this section describe the preparation of pieces from vulcanizates that are too thick, have uneven surfaces, or contain textiles.
