Permissible core material forms include those with continuous bonding surfaces such as balsa wood and foams as well as those with discontinuous bonding surfaces such as honeycomb.

The values stated in each system may not be exact equivalents; therefore, each. Combining values from the two systems may result in non-conformance with the standard. It is the responsibility of the user of this standard to establish appro- priate safety and health practices and determine the applica- bility of regulatory limitations prior to use.

No further reproductions authorized. The mass of absorbed water may also affect the behavior of sandwich structures. It should be noted that in a sandwich panel the presence of facings bonded on two sides of the core may affect the amount of water absorbed by the core. Important aspects of sandwich core specimen preparation that contribute to data scatter include the existence of joints, voids or other core discontinuities, out-of-plane curvature, and surface roughness.

Cracks in the specimen and rough surfaces can increase the. Sampling and Test Specimens. Report the method of sampling. The recommended specimen size is Record and report the specimen cutting preparation method. Pre-Test Conditioning.

After weighing, immedi-. When reducing the vacuum level, ambient venting air should be passed through a calcium sulfate desiccant or suitable alternate in-line trap. The accuracy of these measurements shall be within 0. Measure the specimen length, width and thickness with an accuracy of 6 0. Immerse the specimens in a container horizontally under For materials that tend to collect water on the surfaces or trap water in corners, dip the specimen. Other temperatures, relative humidities, and lengths of time can be.

After conditioning, allow the specimens to cool to room temperature. For materials that tend to collect water on the surfaces or trap water in corners, dip the specimen in isopropyl alcohol, shake vigorously, allow the alcohol to evaporate, and immediately weigh and record the mass.

When surface water on the specimens presents such problems, determine the amount of surface water left on the specimens using the following procedure:. Retests shall be performed for any specimen on which values are not calcu- lated.
