SCOPE The material defined by these specifications is needled, nonwoven glass fiber batt, with no resin or organic fibers added for bonding. 2. APPLICATION These specifications were released
3、originally for material used as a thermal insulator in load bearing areas for 1981 floor pans in the area of the thermactor thermal switch and over the catalytic converter. 3. REQUIREMENTS Material specification requirements are to be used for initial qualification of materials. 3.0 STANDARD REQUIRE
4、MENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). 3.3 CONSTRUCTION The fibers shall be mechanically opened and needled. The fibers used shall not be less than 1.0 in (25 mm) in length. Th
5、e fiber diameter shall be 0.00035 in (8.9 mm) average, with 85% under 0.00040 in (10.2 mm). 3.4 COMPOSITION 3.4.1 Fiber 97 - 99% glass fiber (Type “E“ or equivalent) 3.4.2 Organic Materials 1 - 3% organic weaving lubricant 3.5 THICKNESS Average of 5 readings (FLTM BN 023-02) A1/B1 0.42 +/- 0.06 in (

Apply a 12 x 12 in (305 x 305 mm) platen weighing 1/2 lb (0.23 kg) to the five plied samples. Measure the he
10、ight of the pile, at the center of the vertical skies. (The average of these readings is the initial thickness of the pile (T1). Apply a 5 lb (2.3 kg) load to the center of the pile and measure again for average thickness of the pile with load (T2). T1 - T2 % Compression = - x 100 T1 Remove the load
11、 and allow pile (with platen) to recover thickness for 30 min. Measure again for average thickness of the pile (T3).

12、ERIES FLAMMABILITY 3.10.1 In order to comply with Federal Motor Vehicle Safety Standard No. 302, the materials, portions of components, and composites shall not burn, or transmit a flame across its surface, at a rate of more than 4 in (101 mm) per min. To demonstrate compliance, the sample size and
13、method of testing shall be in accordance with FLTM BN 024-02. 3.10.2 Performance - Environmental Aging All materials, portions of components, and composites defined by this specification that have not been treated, modified or reformulated and exceed a max burn rate of 3.0 in (76 mm) per min as spec
14、ified by the Flammability Lot Sampling Plan of FLTM BN 024-02, must be evaluated for permanency of the materials flame retardant properties per ESB-M25P3-A according to the accelerated environmental aging requirements applicable to the basic material category of this particular specification. Any ma
15、terial, portions of components, and composites defined by this specification that have been treated, modified or reformulated to conform to Flammability Lot Sampling Plan of FLTM BN 024-02, regardless of max burn rate, must be evaluated for both permanency of materials flame retardant properties and
16、 changes in mechanical, chemical and physical properties per ESB-M25P3-A applicable to the basic materials category of this particular specification. 3.10.3 Flammability Test Program Materials, portions of components, and composites governed by this specification must also comply with the requiremen
17、ts of ES-D3AB-11014-AA. 3.11 ESB-M12G74-A SERIES FLAMMABILITY, max 4 in (101 mm)/min (FLTM BN 024-02, without the lot sampling plan) In addition, the test specimen shall not exhibit any flashing or sudden flaming on either surface in excess of the above maximum value. 3.12 DYNAMIC FLEX FATIGUE For I
18、nitial Qualification Only (FLTM BO 012-04, Method “B“*, 150 cycles) *A1/B1 Use 30 lb (133 N) load *A2/B2 Use 60 lb (267 N) load No separation or destruction by breakage of the glass fibers along the rubbing track of the simulated heel both before and after heat aging. Test Method: Prepare two, 10 x
19、10 in (250 x 250 mm) samples of the glass fiber batt. Heat age one sample for 2 h at 205 C and condition at 23 +/- 2 C for 4 h. Staple both samples adjacent to each other on a 10 x 20 in (250 x 500 mm) medium to lightweight pile carpet, (ESB-M3H20 or ESB-M3H30 type). Conduct the test as indicated ab
20、ove, making sure the simulated heel passes over both paddings in the same stroke.
