If aztm are no relevant ASTM material specifications, then the default conditions in this method apply. If the material does not have forming skins, the term overall density is not applicable. Hold the pressure of the dial foot to 2. For calculation of the apparent overall density, cut a specimen that includes the forming skin.

Current edition approved April 1, Highly open-celled materials are essentially air-? 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. There are no recognized standards on which to base an estimate of bias for this test method.

The values given in parentheses are for information only. Combining values from the two systems may result in non-conformance with the standard. The principles of 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.

The specimens shall be taken from locations distributed throughout the sample. 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.

For each material, all the samples were prepared at one source, but the individual specimens were prepared at the laboratories that tested them. Do not use a steel rule for dimensions less than 25 mm 1 in. If there are no relevant ASTM material speci? Originally approved in Referenced Documents 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: However, freshly produced closed-cell materials are essentially air-void and will exhibit maximum buoyant effects of air. Last previous edition approved in as D – Historical Version s – view previous versions of standard. Work Item s – proposed revisions of this standard.

Each laboratory obtained one test result for each d16222. Revised Material 4 repeatability interval, Ir. Density can be evaluated as the apparent overall density includes forming skins or by apparent core density forming skins removed.

Spray equipment shall be adjusted to the best spray pattern and optimum performance. 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.

NOTE 3—The air buoyancy effect will vary with time and depends on the open-cell content of the foam. SR is the between-laboratories standard deviation of the average. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.

Any test specimen preparation, conditioning, dimensions, or testing parameters, or combination thereof, covered in the relevant ASTM materials speci? Note 1 — This test method is equivalent to ISO Spray apply a minimum 1.

Revised Average value for Material 3 in Table 1. VR is the between-laboratories coefficient of variation of the average. Thus, the value of Wa is zero in the above calculation when the sample is at equilibrium with the air. Measurements per Dimension 1 2 In this case, the test specimen is the entire sample. In these cases the pressure shall be reduced accordingly. April 1, 1 Added new 1. After a minimum of 5 min, spray apply a second layer of 3.

If the material does not have forming skins, the term overall density is not applicable. Measure all dimensions to a precision of This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?

Precision and Bias4 The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. 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.

For calculation of core density, remove sstm bottom layer and the top skin. This standard has been approved for use by agencies of the Department of Defense.
