This standard is issued under the fixed designation C ; the number immediately 1 This test method is under the jurisdiction of ASTM Committee C- 16 on. ASTM C () Standard Test Method for Thermal Performance of Building Materials and Envelope Assemblies by Means of a Hot Box Apparatus. Annual. Our calibrated hot box is one of the largest in the country accepting test assemblies up to 9’x16′. Its design allows any orientation from fully vertical to fully .

The equipment performing these measurements requires calibration to ensure that the data are accurate. Detailed heat flow analysis shall precede the use of the hot box apparatus for large, complex structures. If the hot box apparatus has been designed, constructed and operated in the ideal manner, no further calibration or adjustment would be necessary. Some hot boxes are limited to planar or nearly planar specimens. Since this test method is used to determine the total heat flow through the test area demarcated by the metering box, it is possible to determine the heat flow through a building element smaller than the test area, such as a window or representative area of a panel unit, if the parallel heat flow through the remaining surrounding area is independently determined.
A need exists for accurate data on heat transfer through insulated structures at representative test conditions.

Detailed operating procedures, including design schematics and electrical drawings, shall be available for c13633 apparatus to ensure that tests are in accordance with this test method. In addition, there would be no temperature differences that would drive heat across the boundary of the metering chamber walls. We’d be happy to work with you to conduct custom thermal testing for your residential building system. Scientific Research An Academic Publisher.
If no applicable standard exists, sound engineering judgment that reflects accepted heat transfer principles must be used and documented. Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. You may delete a document from your Alert Profile at any time. Whatever the test orientation, the apparatus performance shall first be verified at that orientation with a specimen of known thermal resistance in place.
Additional characterization is required to insure that all aspects of the heat flow and storage are accounted for during the test. These panels, or representative sections of the asttm, have had their thermal performance measured on other devices that are directly traceable or have been favorably compared to a national standards laboratory.
This standard is also available to be included in Standards Subscriptions.
In addition, there would be no temperature differences that c136 drive heat across the boundary of the metering chamber walls. This benchmarking provides substantial astk that any extraneous heat flows can be eliminated or quantified with sufficient accuracy to be a minor factor of the overall uncertainty. By performing this benchmarking process, the hot box operator is able to develop the additional equations that predict the magnitude of the corrections to the net heat flow through the specimen that account for any hot box wall loss and flanking loss.
Large-Scale Hot Box
In this type of testing, bigger d1363 definitely better. If no applicable standard exists, sound engineering judgment that reflects accepted heat transfer principles must be used and documented. Through our network of over 43, people in 1, laboratories and offices in countries, Intertek provides quality and safety solutions to a wide range of industries around the world.
Detailed design of that type of apparatus is beyond the scope of this method. Note that the use of Test Method C or similar apparatus creates additional uncertainty since those devices are calibrated using transfer standards or axtm reference materials. Please enter a valid email address.
A Hot Box is a specially-calibrated instrument in the Home Innovation building product testing lab designed to measure heat flow for large building specimens. The Hot Box removes any concerns that modeling parameters and assumptions c11363 incorrect because the test is conducted on actual wall or ceiling specimens, allowing our building science experts to determine the answer with a high degree of confidence.
To gain this final confidence in the test result, it is necessary to benchmark the overall result of the hot box asym by performing measurements on specimens having known heat transfer values and comparing those results to the expected values. Inspection Validating the specifications, value and safety of your raw materials, products and assets.
This method is also used to measure the thermal performance of a building material at standardized test conditions such as those required in material Specifications CCC and Practice C Air infiltration or moisture migration can alter the net heat transfer. The hot box test method is more suitable for c3163 such data for large building elements, usually of a built-up or composite nature, which are exposed to temperature-controlled air on both sides.
Hybrid and Reflective Insulation Assemblies for Buildings. The same apparatus may be used in several orientations but may require special design capability to permit repositioning to each orientation.
When constructed to measure heat transfer in the vertical direction, the hot box astj used for testing roof, ceiling, floor, and other horizontal structures. Link to Active This link will always route to the current Active version of the standard. Any exterior wall or roof assembly, including steel stud wall systems, insulated concrete forms, tilt-up concrete walls, and insulated metal c163 Test Procedure: As 1c363, the hot box is considered a primary method and the uncertainty of the result is analyzed by direct evaluation of the component measurement uncertainties of the instrumentation used in making the measurements.
