Solothurn, Switzerland June 25, 2014 Recommendations for Insulation Radiant Panel AC Randy Smith, Associate Technical Fellow, Boeing Commercial Airplanes
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 AR • Susahn Bodeutsch – Flammability AR • Keith Couilliard – Flammability AR • Hank Lutz – Technical Principle, Flammability Lab • Steve Moffitt, Flammability Lab • Mary Pacher – Flammability AR • Randy Smith – Associate Technical Fellow, Insulation Design • Sara Walter – Boeing Research and Technology • Since the release of the AC in 2005, Boeing has gained considerable experience with certifying new insulation designs and conducting the radiant panel test
Recommendations for Insulation Radiant Panel AC • Boeing provided the recommendations to the FAA Technical Center at the following times: • During the ARAC activity • During the March 2014 materials group meeting (Savannah) • During a telephone conference in April 2014 • The FAA Technical Center incorporated a majority of the Boeing recommendations into AC and Workbook placeholder documents sent to task group members May 2014 • In 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 recommendations • To improve and clarify test methods • To harmonize acceptable means of compliance within Boeing for certification projects and to harmonize with Industry • Examples of Improvements and Clarifications • Clarify that data from incorrectly constructed samples can be thrown out • Introduce floating thickness range testing for foam (like large panels) • Hook and loop holding frame and specimen position changes • Move damping systems content to the “Test Sample Construction” section where other specialized test configuration information is found • Clarify duct insulation categories and requirements
Recommendations for Insulation Radiant Panel AC • Examples of Harmonizing Acceptable Means of Compliance • Testing for multiple layers of batting and batting density combinations • Passing materials that are sandwiched between batting layers do not have to be included in batting test • Testing quilted blankets acceptable means for showing thread complies • 1” Quilting pattern size acceptable for showing more course patterns comply • Test thinnest foam for bonded foam designs • Any thickness of foam for testing tape on foam • Testing double-sided tape (adhesive on both sides) • Passing auxiliary materials (e.g., felt and coated fabrics) materials on the surface of a blanket tested on standard blanket
