This procedure measures the resistance to radiant heat flow of insulating materials in sleeve, tubing or tape (collectively referred to as “sleeve”) form. The sleeve’s effectiveness (SE) is determined by measuring the difference in surface temperature of a flat black, single-diameter ceramic cylinder with and without the standard diameter sleeve at the specified temperature, position, and distance from the radiant heat source.
Rationale
This standard is being revised to clarify the graphics for the test set-up, to clarify the dimensions of the radiant heat source, and to define a new ceramic cylinder to replace the previous one, which is no longer available.
SAE J2302 has been reaffirmed to comply with the SAE Five-Year Review policy.
The Harness Covering Committee is part of the Electrical Distribution Systems Standards Committee that reports to the Electrical Systems Group of the Motor Vehicle Council. The Committee is responsible for developing and maintaining SAE Standards, Recommended Practices, and Information Reports related to the technology that treats the physical protection of wiring harnesses and those components responsible for physical protection. Test methods and specifications associated with those components are included in the scope. Participants in the Harness Covering Committee include OEMs, suppliers, consulting firms, government, and other interested parties.
* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.

SAE MOBILUS® Search Tips
Please note: All terms not contained within quotes, will be evaluated using the OR operator. This means that your search results will contain all results that contain ANY of the entered terms.
AND, OR, NOT
SAE MOBILUS supports the use of the AND, OR and NOT BOOLEAN operators ONLY function with the Advanced Search.
Wild Cards
Using the asterisk, ( * ) allows you to search for a partial word. For example, entering a keyword search of aero* will search for any word beginning with aero.
Using the question mark, ( ? ) allows you to search for a word with a single character wildcard. For example, searching for t?re would match both tire and tyre
Using Quotes
Words in double quotes " " are treated as a phrase. Conducting a search for "heat model" will return all results in which the exact phrase "heat model" is found, while "heat modeling" would NOT be included.
A term combined with a phrase will be joined with an OR operator.
Searching for Standards
When searching for a standard please use the entire Document Number assigned, which includes the abbreviation. A space can be used, or omitted between the abbreviation and number.
