In this case the calculation for ast is identical to the calculation in A lesser number may be made when the following conditions apply: Any test specimen preparation, conditioning, dimensions, or testing parameters, or combination thereof, covered in the relevant ASTM materials speci?
The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
If the material does not have forming skins, the term overall density is not applicable. Current edition approved April 1, The specimens shall be taken from locations distributed throughout the sample.
Last previous edition approved in as D – Note 1 — This test method is equivalent to ISO 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.
Work Item s – proposed revisions of this standard. Any test specimen preparation, conditioning, dimensions, or testing parameters, or combination thereof, covered in the relevant ASTM materials specification shall take precedence over those mentioned in this test method. 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.
If there are no relevant ASTM material specifications, then the default conditions in this method apply.
Hold the pressure of the dial foot to 2. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.

For calculation of the apparent overall density, cut a specimen that includes the forming skin. Revised Average value for Material 3 in Table 2. It is the responsibility of the user of this standard to establish appropriate safety and d16222 practices and determine the applicability of regulatory limitations prior to use. SR is the between-laboratories standard deviation of the average.

In these cases the pressure shall be reduced accordingly. For each material, all the samples were prepared at one source, but the individual specimens were prepared at the laboratories that tested them. If the material does not have forming skins, the term overall density is not applicable.
