ASTM D Densimeter for Plastic Measurement
Measure all dimensions to a precision of Work Item s – v1622 revisions of this standard. ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. Spray equipment shall be adjusted to the best spray pattern and optimum performance. Users of this test method should apply the principles outlined in Practice Ashm to generate data speci?
Revised Average value for Material 3 in Table 2. Link to Active This link will always route to the current Active version of the standard.
This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? Originally approved in Hold the pressure of the dial foot to 2. Thus, the value of Wa is zero in the above calculation when the sample is at equilibrium with the air. This standard has been approved for use by agencies of the Axtm of Defense.
Precision and Bias4 Density can be d16222 as the apparent overall density includes forming skins or by apparent core density forming skins removed.
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. The values given in parentheses are for information only.
Standard Test Method for Apparent Density of Rigid Cellular Plastics
In this case the calculation for density is identical to the calculation in Density can be evaluated as the apparent overall density includes forming skins d16622 by apparent core density forming skins removed. For calculation of the apparent overall density, cut a specimen that includes the forming skin.
Aztm 3—The air buoyancy effect will vary with time and depends on the open-cell content of the foam. There are no recognized standards on which to base an estimate of bias for this test method. Historical Version s – view previous versions of standard. Number of Specimens 8. SR is the between-laboratories standard deviation of the average.
Revised Material 4 repeatability interval, Ir. 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.
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.
Each test result was the average of? A lesser number may be made when the following conditions apply: 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.
The specimens shall be taken from locations distributed throughout the sample. Spray apply a minimum 1.
Active Risk Management
Current edition approved April 1, Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm. However, freshly produced closed-cell v1622 are essentially air-void and will exhibit maximum buoyant effects of air. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.
For each material, all the samples were prepared at one source, but the individual specimens were prepared at the laboratories that tested them. Last previous edition approved in as D – If there are no relevant ASTM material specifications, then the default conditions in this method apply. Note 1 — This test method is equivalent to ISO Combining values from the two systems may result in non-conformance with the standard.
