ASTM D – 08 Standard Test Method for Apparent Density of Rigid Cellular Plastics
Note 1 — This test method is equivalent to ISO Measure all dimensions to a precision of If there are no relevant ASTM material speci? Hold the pressure of the dial aztm to 2. 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.
For calculation of core density, remove the bottom layer and the top skin. A number in parentheses indicates the year of last reapproval. In general, three measurements shall be made of each dimension. Revised Average value for Material 3 in Table 2.
Revised Material 4 repeatability interval, Ir. When a sliding caliper gage is used, the proper setting shall be that point at which the measuring faces of the gage contact the surfaces of the specimen without compressing them. 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.
Each laboratory obtained one test result for each material. Last previous edition approved in as D – Do not use a steel rule for dimensions less than 25 mm 1 in. A lesser number may be made when the following conditions apply: ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard.
If the material does not have forming skins, the term overall density is not applicable.

This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? Spray apply a minimum 1.
D1262 specimens shall be taken from locations distributed throughout the sample. This standard has been approved for use by agencies of the Department of Defense. Combining values from the two systems may result in non-conformance with the standard.
Density can be evaluated as the apparent overall density includes forming skins or by apparent core density forming skins removed. For calculation of the apparent overall density, cut a specimen that includes the forming skin. Work Item s – proposed revisions of this standard.
If there are no relevant ASTM material specifications, then ast default conditions in this method apply.
