Kowalski, NA Controlled document at www.MATS Copyright 2017, Ford ; Global Technologies, LLC Page 1 of 3 TUBE, POLYAMIDE 12 (PA12) COVER, POLYAMIDE 9T (PA9T) TUBE, WSS-M98D33-A15 LOW PRESSURE, FUEL/ALCOHOL RESIS

2、TANT, NON-CONDUCTIVE, LOW PERMEATING 1. SCOPE This specification defines a multilayered tubing with a non-conductive inner layer. The construction has low permeation rates and good resistance to fuel/alcohol blends. 2. APPLICATIONS This specification was released originally for flexible fuel vapor l

3、ines requiring low permeation. The maximum working pressure should not exceed 104 kPa. Long term continuous operating temperature should not exceed 100 C and maximum intermittent temperature should not exceed 115 C. These lines will meet the requirements of the US market for both reformulated and fl

4、exible fuels. 2.1 LIMITATIONS The requirements listed in this specification represent values based on vehicle operating conditions that do not exceed 0.6 MPa fuel pressure. If the fuel system is expected to exceed this pressure this construction is not appropriate for these applications. 3. REQUIREM

5、ENTS 3.1 APPROVED SOURCES This specification requires the use of approved 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

6、 available externally through a Ford Materials Engineer. 3.2 CONDITIONING AND TEST CONDITIONS All test values are based on material conditioned for not less than 24 h prior to testing in a controlled environment of 23 +/- 2 C and 50 +/- 5% relative humidity. Testing of the material should occur in t

7、he conditioning environment or soon after removal. 3.3 INFRARED SPECTROPHOTOMETRY AND/OR THERMAL ANALYSIS IR spectra and thermograms from initial material approval shall constitute the reference standard and shall be kept on file at the designated material laboratory. The material supplier shall ens

8、ure that all future material supplied to the specification shall produce IR spectra and thermograms that correspond to the reference standard when tested under the same conditions. 3.4 INITIAL QUALIFICATION Suppliers seeking approval to this specification must meet the initial qualification processe

9、s that include evaluating materials and constructions according to the applicable Fuel System Design Specification (SDS) and individual Design Verification Methods (DVM).
