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. Revised Average value for Material 3 in Table 1. For calculation of core density, remove the bottom layer and the top skin.
The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. NOTE 3—The air buoyancy effect will vary with time and depends on the open-cell content of the foam. Density can be evaluated as the apparent overall density includes forming skins or by apparent core density forming skins removed.

The specimens shall be taken from locations distributed throughout the sample. This standard has been approved for use by agencies of the Department of Defense.
Any test specimen preparation, conditioning, aztm, or testing parameters, or combination thereof, covered in the relevant ASTM materials specification shall take precedence over those mentioned in this test method. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?

If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below. Users of this test method should apply the principles outlined in Practice E d1622 generate data speci? VR is the between-laboratories coefficient of variation of the average.
Precision and Bias4 Note 1 — This test method is equivalent to ISO If the material does not have forming skins, the term overall density is not applicable.
ASTM D Densimeter for Plastic Measurement
Originally approved in In these cases the pressure shall be reduced accordingly. In general, three measurements shall be made of each dimension. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. Combining values from the two systems may result in non-conformance with the standard. April 1, 1 Added new 1. Current edition approved April 1, 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.
Measure all dimensions to a precision of Thus, the value of Wa is zero in the above calculation when the sample is at equilibrium with the air. Number of Specimens 8. A number in parentheses indicates the year of last reapproval. For each material, all the samples were prepared at one source, but the individual specimens were prepared at the laboratories that tested them.
Spray apply a minimum 1.
