Preparation of Pieces 7.
Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. 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. Adjustments should be available to vary the thickness of cut, and feed rollers should be provided to transport the material past the knife.
The successive cuts should be progressively thinner to avoid over-heating.
In operation the depth of cut should not exceed approximately 0. 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.
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.
Such pieces are used ast, a source from which specimens are obtained for testing. Equipment should be provided for slow feeding of the wstm to the abrasive band and for securing the material without excessive deformation Note 3. A number in parentheses indicates the year of last reapproval.
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. The knife should be asym with a mild soap solution to ease the cutting operation. 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. An adjustable slow-feed mechanism is? Uneveness of surface may result from contact with fabric components, cutting techniques, or other reasons.
Do not carry out buffing beyond the point where unevenness of thickness has been eliminated. Some skiving machines can separate plies of rubber as in belts, hose, and tires see 7. NOTE 2—Wheels of to mm 5 to 6-in.

Provision should be made for continuous sharpening of the cutting edge. A superscript epsilon e indicates an editorial change since the last revision or reapproval. Suitable means should be provided for securing the rubber to prevent excessive deformation and for controlled asym of the rubber pass the abrasive wheel Note 2. The pieces shall be prepared in accordance with Section 7. This standard has been approved for use by agencies of the Department of Defense.
The abrasive bands should be of textile or paper, or a combination of the two, with the wstm based on aluminum oxide or silicon carbide bonded to its surface with a resin unaffected ashm water. The sheets shall have d183 of the following thicknesses unless another thickness is technically necessary: Procedures are given for preparing pieces suitable for preparing specimens of the product. Originally published as D — 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.
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.

Attachments are available for splitting and cutting sections d31183 cable sheathing and hose. Procedures in this section describe the preparation of pieces from vulcanizates that are too thick, have uneven surfaces, or contain textiles. If this is not possible, use commercial isooctane.
