ASTM C177 FREE DOWNLOAD

This standard is not included in any packages. Annex A1 is referenced to the user, which addresses such issues as limitations of the apparatus, thickness measurement considerations and measurement uncertainties, all of which must be considered in the design and operation of the apparatus. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Test thickness, temperature range, temperature difference range, ambient conditions and other system parameters must also be selected during the design phase. The user should consult the standard practices on the single-sided mode of operation, Practice C , and on the line source apparatus, Practice C , for further details on these heater designs. It covers a wide variety of apparatus constructions, test conditions, and operating conditions. Standardization of this test method is not intended to restrict in any way the future development of new or improved apparatus or procedures.

If no applicable standard exists, sound engineering judgment that reflects accepted heat transfer principles must be used and documented. It is possible that any inhomogeneity or anisotropy astm c177 the specimen will require special experimental precautions to measure that flow of heat.

This standard does not purport to address all of the safety concerns, if any, associated with its use. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. Random and Systematic Error Components. Limitations Due to Specimen. We have no amendments or corrections for this standard. Work Item s – proposed revisions of this standard. As the voice of the U.

Both distributed and line source guarded heating plate designs are permitted. Standardization of this test method is not intended to restrict in any way the future development of new or improved apparatus or procedures. Many advances have been made in thermal technology, both in measurement techniques and in improved understanding of astm c177 principles of heat flow through materials. This test method is comparable, but not identical, to ISO Subscription pricing is determined by: For this reason, conformance with the test method requires that the user must estimate and aatm the uncertainty of the results under the reported test conditions.

Examples of analysis tools, concepts and procedures used in the design, construction, calibration and operation of a guarded-hot-plate apparatus are given in Refs Limitations Due to Temperature. Already Subscribed to this document. astm c177
