ASTM E307, 72nd Edition – Standard Test Method for Normal Spectral Emittance at Elevated Temperatures

ASTM E307 test method describes a highly accurate technique for measuring the normal spectral emittance of electrically conducting materials or materials with electrically conducting substrates, in the temperature range from 600 to 1400 K, and at wavelengths from 1 to 35 μm.

The test method requires expensive equipment and rather elaborate precautions, but produces data that are accurate to within a few percent. It is suitable for research laboratories where the highest precision and accuracy are desired, but is not recommended for routine production or acceptance testing. However, because of its high accuracy this test method can be used as a referee method to be applied to production and acceptance testing in cases of dispute.

The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.

This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

These standards cover:

Space Simulation —specifications and practices cover contamination of cleanrooms and controlled environments, space simulation, and thermal protection.

Aerospace and Aircraft —standards deal with cleaning materials, flammability, contamination, hydrogen embrittlement, transparent enclosures, and materials.

Composite Materials—test methods assess properties of high modulus fibers, interlaminar properties, laminates, sandwich construction, and structural test methods.
