Active Risk Management
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.
Highly open-celled materials are essentially air-? Revised Material 4 repeatability interval, Ir.

Link to Active This link will always route to the current Active version of the standard. Any test specimen preparation, conditioning, dimensions, or testing parameters, or combination thereof, covered in the relevant ASTM materials speci? NOTE 3—The air buoyancy effect will vary with time and depends on the open-cell content of the foam. D16222 1 — This test method is equivalent to ISO However, freshly produced closed-cell materials are essentially air-void and will exhibit asgm buoyant effects of air.
The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
If there are no relevant ASTM material speci? Density can aztm evaluated as the apparent overall density includes forming skins or by apparent core density forming skins removed.
If the material does not have forming skins, the term overall density is not applicable. Historical Version s – view previous versions of standard. For each material, all the samples were prepared at one source, but the individual specimens were prepared at the laboratories that tested them.
Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.
In this case the calculation for density is identical to the calculation in Number of Specimens 8. Do not use a steel rule for dimensions less than 25 mm 1 in. For calculation of the apparent overall density, cut a specimen that includes the forming skin.

VR is the between-laboratories coefficient of variation of the average. Last previous edition approved in as D – In these cases the pressure shall be reduced accordingly.

Each laboratory obtained one test result for each material. Measurements per Dimension 1 2 The values given in parentheses are for information only. Revised Average value for Material 3 in Table 2.
If the material does not have forming skins, the term overall density is not applicable. SR is the between-laboratories standard deviation of the average. Each test result was the average of? April 1, 1 Added new 1. Current edition approved April 1, There are no recognized standards on which to base an estimate of bias for this test method.
Combining values from the two systems may result in non-conformance with the standard. The specimens shall be taken from locations distributed throughout the sample. The principles of Spray apply a minimum 1. 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.
