Recommendations for Insulation Radiant Panel AC
Boeing personnel met numerous times to develop a list of recommended improvements to the AC document:Matt Anglin – Associate Technical Fellow, Flammability ARSusahn Bodeutsch – Flammability ARKeith Couilliard – Flammability ARHank Lutz – Technical Principle, Flammability LabSteve Moffitt, Flammability LabMary Pacher – Flammability ARRandy Smith – Associate Technical Fellow, Insulation DesignSara Walter – Boeing Research and TechnologySince the release of the AC in 2005, Boeing has gained considerable experience with certifying new insulation designs and conducting the radiant panel test
Boeing provided the recommendations to the FAA Technical Center at the following times:During the ARAC activityDuring the March 2014 materials group meeting (Savannah)During a telephone conference in April 2014The FAA Technical Center incorporated a majority of the Boeing recommendations into AC and Workbook placeholder documents sent to task group members May 2014In the placeholder documents, some of the content of the current AC was moved to the Workbook, so the Boeing recommendations moved with that content
Recommendations for Insulation Radiant Panel AC
Goals of recommendationsTo improve and clarify test methodsTo harmonize acceptable means of compliance within Boeing for certification projects and to harmonize with IndustryExamples ofImprovementsand ClarificationsClarify that data from incorrectly constructed samples can be thrown outIntroduce floating thickness range testing for foam (like large panels)Hook and loop holding frame and specimenposition changesMove damping systems contentto the “Test Sample Construction” section where other specialized test configuration information is foundClarify duct insulation categories andrequirements
Recommendations for Insulation Radiant Panel AC
Examples of Harmonizing Acceptable Means of ComplianceTesting for multiple layers of batting and batting density combinationsPassingmaterialsthatare sandwiched between batting layers do not have to be included in batting testTesting quilted blankets acceptable means for showing thread complies1” Quilting pattern size acceptable for showing more course patterns complyTestthinnest foam for bonded foam designsAny thickness of foam for testing tape on foamTestingdouble-sided tape (adhesive on both sides)Passingauxiliary materials (e.g., felt and coated fabrics) materials on the surface of a blanket tested on standard blanket
