In this case the calculation for density is identical to the calculation in Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. Measurements per Dimension 1 2 Xstm calculation of the apparent overall density, cut a specimen that includes the forming skin. In this case, the test specimen is the entire sample.
Thus, the value of Wa is zero in the above calculation when the sample is at equilibrium with the air. Combining values from the two systems may result in non-conformance with the standard. Each test result was the average of? Number of Specimens 8. Last previous edition approved in as D – 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.
Density can be evaluated as the apparent overall density includes forming skins or by apparent core density forming skins removed. Users d6122 this test method should apply the principles outlined in Practice E to generate data speci? The values given in parentheses are for information only. For calculation of core density, remove the bottom layer and the top skin. Originally approved in Revised Average x1622 for Material 3 in Table 2.
For each material, all the samples were prepared at one source, but the individual specimens were prepared at the laboratories that tested them. If there are no relevant ASTM material specifications, then the default conditions in this method apply.
Density can be evaluated as the d16222 overall density includes forming skins or by apparent core density forming skins removed.
Highly open-celled materials are essentially air-?
A lesser number may be made when the following conditions apply: Precision and Bias4 ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard.
Any test specimen preparation, conditioning, dimensions, or testing parameters, or combination thereof, covered in x1622 relevant ASTM materials specification shall s1622 precedence over those mentioned in this test method. Spray equipment shall be adjusted to the best spray pattern and optimum performance. 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.
The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. 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. Spray apply a minimum 1. If there are no relevant ASTM material speci?
If the material does not have forming skins, the term overall density is not applicable. The principles of Any test specimen preparation, conditioning, dimensions, or testing parameters, or combination thereof, covered in the relevant ASTM materials speci? In general, three measurements shall be made of each dimension.

The specimens shall be taken from locations distributed throughout the sample. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?
Each laboratory obtained one test result for each d122. Revised Average value for Material 3 in Table 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.

After a minimum of 5 min, spray apply a second layer of 3. There are no recognized standards on which to base an estimate of bias for this test method.
NOTE 3—The air buoyancy effect will vary with time and depends on the open-cell content of the foam. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. Do not use a steel rule for dimensions less than 25 mm 1 in.
Users of this standard are expressly advised that determination of the validity of any such astn rights, and the risk of infringement of such rights, are entirely their own responsibility.
It is the responsibility of the user of this standard to establish appropriate safety astmm health practices and determine the applicability of regulatory limitations prior to use.
