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.

In operation the depth of cut should not exceed approximately 0. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM Headquarters. The successive cuts should be progressively thinner to avoid over-heating.

This standard has been approved for use by agencies of the Department of Defense. A superscript epsilon e indicates an editorial change since the last revision or reapproval. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? Procedures are given for preparing pieces suitable for preparing specimens of the product.

Uneveness of surface may result from contact with fabric components, cutting techniques, or other reasons. 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. For removal of greater thicknesses of rubber, use the cutting techniques indicated in 7.

ASTM D313 e1. 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.

Aztm 3—Grit sizes of 0. The machine consists of a motor- or hand-driven disk cutter of suitable diameter with a sstm cutting table that transports the sample to the cutting edge. 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.

The buffing may be either against the drum, against one of the pulleys, or against the taut band between the pulleys. Current edition approved March 30, 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.

Last previous edition D — Adjustments should be available to vary the thickness of cut, and feed rollers should be provided to transport the d31883 past the knife. It is important that the wheel should run true, without vibration, and that the abrasive surface based on aluminum oxide or silicon carbide is asrm and sharp.

NOTE 1—For production quality control, testing within 1 to 6 h after vulcanization may be necessary to monitor plant operation.

An adjustable slow-feed mechanism is? The abrasive bands should be of textile or paper, or a combination of the two, d3813 the abradant based on aluminum oxide or silicon carbide bonded to its surface with a resin unaffected by water. NOTE 2—Wheels of to mm 5 to 6-in.

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. The pieces shall be prepared in accordance with Section 7.

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 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.

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.

Do not carry out buffing beyond the point where unevenness of thickness has been eliminated. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.

Preparation of Pieces 7. If this is not possible, use commercial isooctane. The sheets shall have one of the following thicknesses unless another thickness is technically necessary:
