SCOPE The material defined by this specification is plastisol compound that imparts sound barrier properties when applied to batt type insulation material. 2. APPLICATION T

3、his specification was released originally for material used on molded and flat dash insulator assemblies. 3. REQUIREMENTS Material specification requirements are to be used for initial qualification of materials. 3.0 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producer

4、s must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). 3.2 APPEARANCE The acoustical coating as received on the reclaimed underlay shall be uniformly smooth in appearance, without the presence of blisters or deep recesses. There shall be no breaks in the cont

6、re not desired and shall be reported along with numerical results but shall not be cause for rejection. 3.5 COLOR STABILITY 120 h (SAE J1885) No more evidence of fading than the master sample retained in BEPE. 3.6 FLEXIBILITY 3.6.1 No evidence of cracking of the acoustical coating when tested as rec

7、eived at 23 +/- 2 C. 3.6.2 No evidence of cracking of the acoustical coating when tested after conditioning the material for 16 h at -23 +/- 1 C. ENGINEERING MATERIAL SPECIFICATION ESB-M99G102-B Copyright 2012, Ford Global Technologies, LLC Page 2 of 3 3.6.3 No evidence of cracking of the acoustical

8、 coating when tested after aging for 72 h at 70 +/- 1 C and then conditioning for 16 h at -23 +/- 1 C. Test Method: Cut 50 x 150 mm samples from flat areas. Strip the acoustical coating from the underlay leaving as little underlay as possible. Bend the samples 180 around a 6.4 mm mandrel for all of

9、the above tests. 3.7 SOLVENT RESISTANCE Shall not become tacky or show any appreciable coating removal when lightly wiped with a white cloth wet with solvent, M-14J148 (light petroleum naphtha). 3.8 HUMIDITY RESISTANCE No evidence of crazing, cracking loss of adhesion nor objectionable odor produced

10、 when a sample of acoustical coating attached to the underlay material is exposed to 95 - 100% relative humidity and 38 +/- 1 C for 5 days. 3.9 HEAT RESISTANCE Shall not flow or show adhesion failure from the underlay material when exposed for 2 hours at 88 +/- 1 C. There shall be no tackiness devel

11、oped to the extent that any color is transferred to white paper toweling. 3.10 ODOR Not objectionable in the “as received“ condition or after the acoustical coating has been exposed in a closed glass container for 2 h at 102 +/- 3 C. The odor level shall not exceed that of the master sample retained

12、 by BEPE. 3.11 STAIN RESISTANCE TO PRODUCTION CARPET 3.11.1 No contact nor migration staining. Test Method: 50 x 50 mm sample of light colored carpet, pile side up, is placed in a Petri dish and saturated with water. Place a 50 x 50 mm sample of dash insulator with the acoustical coating against the

13、 carpet surface with weight over it. Allow the fixture to stand for 4 h and then examine carpet for staining. Repeat Steps 1, 2, and 3 using M-14J148 (petroleum naphtha) instead of water. 3.11.2 No contact nor migration staining Test Method: Place a 50 x 50 mm sample of dash insulator with acoustica

14、l coating against the surface of a 50 x 50 mm sample of light colored carpet, pile side up, in a Petri dish with a 0.45 kg weight over it. Allow fixture to stand in a mechanical convection oven maintained at 70 +/- 1 C for 72 h. Cool to 23 +/- 1 C and examine carpet for staining. 3.12 TENSILE STRENG
