2、THANE FOAM, HIGH AND MEDIUM DENSITY ESB-M4D262-C NOT TO BE USED FOR NEW DESIGN 1. SCOPE The materials defined by this specification are high and medium density, filled or unfilled, flexible polyether urethane foams. 2. APPLICATION This specification was released originally for the following material
3、s: Type I Seat cushions: Molded and slab, high density foam normally used as the support padding for bench and bucket seat cushion constructions and when border or support wires are contained integrally within the foam. Type II Seat backs, Inserts and Center arm rests: Molded and slab, medium densit
4、y foam normally used as the support padding for bench and bucket seat constructions when a lower density, lower load bearing foam is desired and die cut parts for door panel and vacuum shaped seat inserts. 3. REQUIREMENTS 3.0 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part
5、 producers must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). Type I Type II Backs, Inserts 75% constant deflection, shall be computed on original deflection. All set values are obtained on specimens defined by para. 3.1 and 3.2 and the 1 in (25 mm) dimensi
6、on of the test specimen shall be obtained perpendicular to the part surface. For parts less than 1 in (25 mm) thick, two 1/2 in (12.7 mm) thick specimens may be plied up to 1 in (25 mm) thickness with 1/2 in (12.7 mm) dimension cut as above. Computed deflection shall be controlled to +/- 0.002 in (0
7、.05 mm). * Steam Autoclave Aged Test Method: Determine normal compression set on similar test specimens that are steam autoclave aged (as defined in FLTM BO 012-01) for 3 h at 2.8 +/- 1.5 psi (19 +/- 10 kPa) and/or 104 +/- 5 C; then dried 3 h at 70 +/- 1 C in a convection oven, followed by 24 h cond
8、itioning at 23 +/- 2 C and 50 +/- 5% relative humidity. 3.3 ASSEMBLY Type I Cushions: Parts or specimens submitted to BEO for source approval evaluation under this specification, or submitted at the request of the Body Materials Engineering Department must exhibit a 50 lb (222 N) IRGL value that is
9、50 +/- 8% of the 1 lb (4.4 N) IRGL, or as specified on the engineering drawing. Type II Seat backs only: Parts or specimens must exhibit 50 lb (222 N) IRGL of 42 +/- 8% of the 1 lb (4.4 N) IRGL, or as specified on the engineering drawing. 3.3.1 Load Indentation (SAE J 815, steps 1-4 only, parts test
10、ed with top skin, one side; and inserts tested with no skin or as specified on the engineering drawing.) Values as specified on the engineering drawing ENGINEERING MATERIAL SPECIFICATION ESB-M4D262-C Printed copies are uncontrolled Copyright 2006, Ford Global Technologies, LLC Page 3 of 5 3.3.2 Load
11、 Indentation (FLTM BN 015-06) Compression test areas (e.g., bolster and insert areas) and test values shall be as specified on the engineering drawing. 3.4 RESISTANCE TO DETERIORATION 3.4.1 Load Indentation, change from original, max 15% Test Method: Cut a test specimen 6 x 6 x 2 in (150 x 150 x 50
12、mm). Measure the 25 lb (111 N) and 50 lb (222 N) height according to SAE J 815. Expose sample 3 h in steam autoclave, remove and condition per FLTM BO 012-01. Determine heights at 25 lb (111 N) and 50 lb (222 N) after autoclave exposure. Calculate and report the percent height change. % Ht Change =
13、H1 - H2 - H1 H1 = Original height at 25 lb (111 N) or 50 lb (222 N) H2 = Autoclave exposed sample height at 25 lb (111 N) or 50 lb (222 N) 3.4.2 Flexibility No cracking or crumbling Test Method: A specimen 2 x 6 x 1 in (50 x 150 x 25 mm) shall be subjected to autoclave aging (FLTM BO 012-01) and sub
14、sequently bent 180 around a 1/4 in (6.4 mm) diameter mandrel. 3.5 LOW TEMPERATURE LOAD COMPRESSION, change, max 65% (ASTM D 1564, Suffix “D“, test specimen is 6 x 6 x 2 in (150 x 150 x 50 mm) Test Method: At room temperature, determine the initial thickness of the specimen under 1 lb (4.4 N) preload
15、, then the compression load at 25% deflection. Condition the specimen for 5 h at -34 C. Remove from the cold chamber and within 2 min obtain the load value at 25% deflection. Compute the change in compression load. C = E - D x 100 - D C = % change in compression load D = Compression load at room tem
