OCTOBER 2016 Page 2 of 7 4.0 GENERAL REQUIREMENTS Unless otherwise specified on the engineering drawing and/or purchase order, the manufacturing practice and bonding methods are optional. The supplier is responsible to select in
11、dividual components of the composite appropriate for the bonding method selected and so fabricate these as to insure that the finished composite is suitable for its intended use and meets all property and performance requirements specified herein. The following components of the composite may be con
12、sidered typical. Specific materials may be indicated on the engineering print. 4.1 Padding Shall be bondable urethane foam or non-woven padding (Fiberbond). The urethane foam shall meet the requirements of MPAPS L-6505. The non-woven padding (suitable for dielectric bonding only) shall meet the requ
13、irements of MPAPS D-7067. MPAPS L-6606 may be appropriate for some parts, but is not considered a bonded composite and would not be covered by this specification. Some parts may be specified without padding. 4.2 Face Materials Shall meet the requirements designated on the engineering drawing and/or
14、purchase order. Color and pattern shall match approved standards on file in the NAVISTAR Industrial Design Department. The following materials are considered suitable: Fabric: MPAPS D-7113 Carpet and carpet-like trim: MPAPS D-7126 Vinyl coated fabrics and leather: MPAPS D-7121 Rubber Mats: MPAPS L-6
