2、COMPOUND ESB-M4D317-A - ELECTRICAL GRADE NOT TO BE USED FOR NEW DESIGN 1. SCOPE The material defined by this specification is a color pigmented polyvinyl chloride molding compound. This specification offers various durometer hardnesses and a range of physical properties. 2. APPLICATION This specific
3、ation was released originally for material used for molded grommets and insulators used in electrical applications. Colors are utilized for identification purposes only as this material is not intended for use in trim applications. This specification replaces and supersedes ESB-M4G69-A. When ESB-M4G
4、69-A is shown on other documents, the requirements of this specification apply. 3. REQUIREMENTS All tests shall be conducted on finished parts where possible; otherwise, tests shall be conducted on molded 150 x 150 x 1.90 + 0.13 mm slabs, made from production stocks. 3.1 PHYSICAL PROPERTIES Types I

ENGINEERING MATERIAL SPECIFICATION ESB-M4D317-A WP 3948-b Page 3 of 4 3.5 PAINT STAINING There shall be no visible stain produced on the painted panel beyond the boundaries of the test specimen. Test Method: Securely at
12、tach a test specimen 1.90 x 25 x 50 mm to a 75 x 75 mm painted panel. (The panel shall be painted with ESB-M32J100 quality light colored enamel per FLTM BI 3-2.) Expose the assembly in the fluorescent sunlamp cabinet as described in FLTM BO 15-1 for 48 h. Remove the test specimen from the panel and
13、re-expose the painted panel in the fluorescent sunlamp cabinet for 24 h. Remove panel and re-examine for staining. Where acrylic lacquer is employed as the color coat, same procedure is followed. Note: A raised welting of painted surfaces in direct contact with the test specimen resulting from this
14、test method is characteristic of plasticized vinyl compounds and shall not be cause for rejection. This test is applicable only when this material contacts visible painted surfaces. 3.6 STAINING The vinyl shall not stain trim materials which it may contact in assembly. There shall be no evidence of
15、stain on the face of material when tested as follows: Test Method: Place a 150 mm length of vinyl in intimate contact with the back of the trim material normally used in assembly* and expose for 7 days in a fluorescent sunlamp cabinet as specified in FLTM BV 7-2. *Note: For specific information rele
16、vant to the vinyl trim material to be used in this test, contact the design engineer. 3.7 FADE (FLTM BN 1-1) Shall not stain, exhibit color change or change in hue, in accordance with rating 2 of the AATCC Gray Scale for Evaluating Change in Color (10 step) after 80 SFH exposure. 3.8 ODOR Not disagr
17、eeable 3.9 OZONE RATING Must meet (FLTM BP 1-1) ESB-M9P1-A 3.10 H2S STAINING (FLTM AN 2-1) The material shall correspond to a rating of 5 minimum when compared to the AATCC chart for measuring the transference of color. 3.11 SUPPLIERS RESPONSIBILITY All materials supplied to this specification must
18、be equivalent in all characteristics to the material upon which approval was originally granted. ENGINEERING MATERIAL SPECIFICATION ESB-M4D317-A WP 3948-b Page 4 of 4 Prior to making any change in the properties, composition, construction, color, processing or labeling of the material originally app
19、roved under this specification, whether or not such changes affect the materials ability to meet the specification requirements, the Supplier shall notify Purchasing, Toxicology and the affected Materials Engineering activity of the proposed changes and obtain the written approval of the Materials E
20、ngineering activity. Test data, test samples and a new code identification are to be submitted with the request. Substance restrictions imposed by law, regulations or Ford, apply to the materials addressed by this document. The restrictions are defined in Engineering Material Specification WSS-M99P9
21、999-A1, unless a different suffix (e.g., A2 or A3) is specified on the engineering document for the application. 4. APPROVAL OF MATERIALS Materials defined by this specification must have prior approval by the responsible Materials Engineering activity. Suppliers desiring approval of their materials
22、 shall first obtain an expression of interest from the affected Purchasing, Design and Materials Engineering activity. Upon request, the Supplier shall submit to the affected Materials Engineering activity its own laboratory report to the specification (test results, not nominal values), the materia
23、l designation and code number, and test specimens for Ford evaluation. Upon approval, the material will be added to the Engineering Material Approved Source List. 5. GENERAL INFORMATION The information given below is provided for assistance and clarification and does not represent requirements to th
24、ese specifications. Specific part requirements such as compression set, joint strength, etc. shall be shown on the engineering drawing. 5.1 STAINING APPLICABILITY The staining requirements of this specification are applicable only when the material contacts visible surfaces such as paint, interior trim (vinyls or fabrics), etc.
