2、8.0 oz/yd2(0.271 kg/m2) ESB-M17H143-A3 NOT TO BE USED FOR NEW DESIGN 1. SCOPE The material defined by this specification is a blown 100% polyester fiber needled foundation pad of random fiber arrangement. 2. APPLICATION This material was released originally as a padding underlay for 1980 vinyl cover
3、ed exterior roof applications. 3. REQUIREMENTS Material specification requirements are to be used for initial qualification of materials. In addition to the requirements listed herein, the finished assembly must also meet the engineering requirements of ESB-M15P5-A. 3.0 STANDARD REQUIREMENTS FOR PRO
4、DUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). 3.2 APPEARANCE The padding may be colored by addition of a non staining or non bleeding pigmented dye for purpose of supplier identification. This dye
5、 shall not interfere with any of the other material requirements listed herein. 3.3 COMPOSITION Fiber 6 den (0.7 tex) (Polyester, 2 in (50 mm) Staple) 50 +/- 5% 15 den (1.7 tex) (Polyester, 2 in (50 mm) Staple) 50 +/- 5% Binder Thermoplastic Resin 100% 3.4 CONSTRUCTION The fibers shall be arranged i
6、n a random manner, and extend from the top surface to the bottom surface, so that delamination cannot occur at any plane within the thickness of the pad during handling and assembly operations.

Test Method . Take three 4 x 4 in (100 x 100 mm) samples (one from the center and one from
8、 each side, across the roll) and finely chop using a blender or equivalent method. . Place samples in a large tarred weighing bottle and oven dry at 102 +/- 3 C until a constant weight is obtained. Record final sample weight as W1. . Transfer sample to a beaker and add methyl isobutylketone. (Temper
9、ature 38 +/- 3 C). Use a minimum of 15 weights of solvent to one of padding. . Allow sample to stand for 24 h. Stir occasionally. . Filter solution twice through a No. 80 mesh screen filter or equivalent method. . Oven dry at 102 +/- 2 C to a constant weight. Record final fiber weight as W2. . % Bin
