ASTM D / DM – 14 Standard Test Method for Apparent Density of Rigid Cellular Plastics
If there are no relevant ASTM material speci? Measure all dimensions to a precision of Number of Specimens 8. This standard has been approved for use by agencies satm the Department of Defense.
SR is the between-laboratories standard deviation of the average. Density can be evaluated as the apparent overall density includes forming skins or by apparent core density forming skins removed.
ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard.
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. Measurements per Dimension 1 2 Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.
VR is the between-laboratories coefficient of variation of the average. If the material does 1d622 have forming skins, the term overall density is not applicable. Originally approved in Precision and Bias4 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.
Combining values d11622 the two systems may result in non-conformance with the standard.
ASTM D – 98 Standard Test Method for Apparent Density of Rigid Cellular Plastics
For calculation of core density, remove the bottom layer and the top skin. Current edition approved April 1, Revised Average value for Material 3 in Table 1.
After a minimum of ashm min, spray apply a second layer of 3. Each test result was the average of? Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm. If there are no relevant ASTM material specifications, then the default conditions in this method apply.
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. Hold the pressure of the dial foot to 2.
The principles of Density can be evaluated as the apparent overall density includes forming skins or by apparent core density forming skins removed. April 1, 1 Added new 1. In these cases the pressure shall be reduced accordingly.
Referenced R1622 purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. A lesser number may be made when the following conditions apply: Each laboratory obtained one test result for each material. In this case, the test specimen is the entire sample.
Active Risk Management
This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? A number in parentheses indicates the year of last reapproval. Spray apply a minimum 1. For each material, all the samples were prepared at one source, but the individual specimens were r1622 at the laboratories that tested them.
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. Last previous edition approved in as D – Users of this test method should apply the principles outlined in Practice E to generate data speci?

Standard Test Method for Apparent Density of Rigid Cellular Plastics
The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. There are no recognized standards on which to base an estimate of bias for this test method. However, freshly produced closed-cell materials are essentially air-void and will exhibit maximum buoyant effects of air.
