SCOPE This standard defines the material requirements for a polyester substrate with a polymeric adhesive laminating the substrate to an exterior aluminum foil. The polyester subs
3、trate is a combination of polyester monofilament and polyester multifilament. The final product can be either a sleeve version; or a flat tape with a hook and loop closure and a foil overlap to enclose the hook and loop closure. 2. APPLICATION This specification was released originally for material
4、used to provide thermal protection for engine wires used in high temperature applications. 3. REQUIREMENTS Material specification requirements are to be used for initial qualification of materials. 3.1 QUALITY SYSTEM REQUIREMENTS Material suppliers and part producers must conform to the Companys Qua
5、lity System Requirements. 3.2 INFRARED SPECTROPHOTOMETRY AND/OR THERMAL ANALYSIS IR spectra and thermograms established for initial approval shall constitute the reference standard and shall be kept on file at the designated material laboratory. All samples shall produce IR spectra and thermograms t
6、hat correspond to the reference standard when tested under the same conditions. 3.3 CONDITIONING AND TEST CONDITIONS All test values indicated herein are based on material conditioned in a controlled atmosphere of 23 +/- 2 C and 50 +/- 5 % relative humidity for not less than 24 h prior to testing an
7、d tested under the same conditions unless otherwise specified.

Each sample tested is subjected to one of the following fluids: distilled water, 3 % salt water sol
10、ution, 10W-40 motor oil or brake fluid. Samples (including the overlap of the wrappable version) must meet at least one of the following requirements: Achieve peel strength value of 175.13 N/m, min Adhesion to the fabric shall exceed the strength of the aluminum foil substrate. 3.6 LOW TEMPERATURE F
11、LEXIBILITY No sign of cracking or delamination of the foil laminate after the sleeve is held at - 40 C for 5 h, and then wrapped around a mandrel which is 2 times the nominal diameter of the sleeve. Sample length for the test is 304.8 mm. ENGINEERING MATERIAL SPECIFICATION WSS-M99G173-A Page 3 of 3
12、Copyright 2015, Ford Global Technologies, Inc. 3.7 THERMAL ENDURANCE No delamination of the foil from the fabric when the sleeve is held 30 mm above a 538 C radiant heat source for 6 h. Sleeve length to be 304.8 mm. Hose outside diameter to be 3.175 mm less than sleeve diameter. Radiant Heat Source:
13、 PMI heater with a 32 x 7.62 cm flat face black surface or equivalent. (Note: heater output is 1100 watts, 240 volts at maximum power. 537.78 C is not maximum power.) 3.8 SUPPLIERS RESPONSIBILITY All materials supplied to this specification must be equivalent in all characteristics to the material u
14、pon which approval was originally granted. Prior to making any changes to the material originally approved under this specification, whether or not such changes affect the materials ability to meet the specification requirements, the Supplier shall notify the affected Purchasing, and Materials Engin
15、eering activities (with reasons) of the proposed changes. Upon notification of the Company, further instructions will be provided. Note: Suppliers should be prepared to provide test data and samples demonstrating compliance to this specification, if requested. Substance restrictions imposed by regul
16、ations or Company direction applies to the materials addressed by this document. The restrictions are identified in Restricted Substance Management Standard WSS-M99P9999-A1. 4. APPROVAL OF MATERIALS Materials defined by this specification for direct supply to the Company must have prior approval. Ce
17、rtain materials subcontracted by part suppliers may also require prior approval. These include materials critical to the Companys business for regulatory, safety, environmental or compatibility requirements or contractual agreements. Suppliers desiring approval of their materials shall first obtain
18、an expression of interest from Purchasing, Design or Materials Engineering activity. Upon request, the Supplier shall 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 this specification.
