2、EFLECTIVE COVERING, FIBERGLASS WITH WSS-M99G172-A ALUMINUM FOIL THERMAL INSULATOR 1. SCOPE This standard defines the material requirements of a fiberglass textile substrate with aluminum foil laminated to the outer surface, and an acrylic pressure sensitive adhesive on the inner surface of the mater
3、ial. 2. APPLICATION This specification was released originally for material used to provide thermal protection for wire harnesses. 3. REQUIREMENTS Material specification requirements are to be used for initial qualification of materials. 3.1 APPROVED SOURCES This specification requires the use of ap
4、proved sources. Only the sources identified on the Ford Approved Source List (ASL) can be used when this specification is listed on the drawing, CAD file, or other documents. The list of approved sources is located within Ford at or available externally through a Ford Materials Engineer. 3.2 INFRAR

8、 3.7 MATERIAL WEIGHT 250 g/m2 min (ASTM D3776) 3.8 MATERIAL THICKNESS 0.2 mm min (ASTM D1777) 3.9 FLUID RESISTANCE Test Procedure: A 2 x 5 inch sample is applied to a stainless steel plate with the same dimensions. A second sample, 1.5 x 4.5 inches, is applied over the first sample. The entire test
9、piece is immersed into one of the automotive fluids until the sample is soaked. After 1 h, 24 h, 48 h, and 72 h, the sample is visually examined for flagging, peeling or any other sign of degradation. The material passes this test when exposed to any one of the following fluids: gasoline, diesel fue
10、l, brake fluid, windshield washer fluid, 10W-40 motor oil, automatic transmission fluid, engine cleaner, 50 % antifreeze, or battery acid. 3.10 FOGGING (SAE J1756, 3 h at 100 C heating, 21 C cooling plate, post test conditioning 1 h and 16 h) Fog Number 80 min Formation of clear film, droplets or cr

GENERAL INFORMATION The information given below is provided for clarification and assistance in meeting the requirements of th
13、is specification. Contact for questions concerning Engineering Material Specifications. 4.1 APPROVAL OF MATERIALS Suppliers desiring approval of their materials shall first obtain an expression of interest from Purchasing, Design or Product Development, and Materials Engineering. The supplier shall
14、 submit a completed copy of their laboratory test reports, signed by a qualified and authorized representative of the test facility, demonstrating full compliance with all the requirements of the Material Specification. Tested material samples must be available for review upon request and kept for a
15、 minimum of one year. Upon request, the supplier will review the associated quality control documents (Process Failure Mode and Effects Analysis, Control Plans, Certification testing) with Ford. 4.2 SUPPLIERS ONGOING RESPONSIBILITY All materials must be equivalent in all characteristics to the mater
16、ial upon which approval was originally granted. Prior to making any changes to the material originally approved, whether or not such changes affect the materials ability to meet the specification requirements, the supplier shall notify the affected Supplier Technical Assistance (STA), Purchasing, an
17、d Materials Engineering activities of the proposed changes (with reasons) by submission of a completed Suppliers Request for Engineering Approval, SREA. For parts and components using Ford Engineering Material Specifications, all samples tested to the specifications for Design Verification (DV), Pro
18、duction Verification (PV) and Production Part Approval Process (PPAP) sign off must be kept until Job 1. 4.3 RESTRICTED SUBSTANCE MANAGEMENT STANDARD Substance restrictions imposed by regulations or Company direction applies to the materials addressed by this document. The restrictions are identifie
19、d in the Restricted Substance Management Standard WSS-M99P9999-A1 which is updated yearly. It is the suppliers responsibility to comply with this standard on a continuing basis through IMDS and or GMAP reporting. 5.
