Dear Mr. Nakajima: This is in reply to your letter of June 19, 1972, concerning th application of Standard No. 302, 'Flammability of Interior Materials,' to a pocket which is attached to a front seat back. You ask whether, under S4.2 of the standard, the upper portion of the sample will be tested as an assembly, as this is the manner in which it appears in the vehicle. The upper portion of the sample consists of one material folded over itself, with an adhesion process joining the folded segments at points approximately 3/4 inch apart, across the length of the material. An elastic band is inserted in the fold of the material. The configuration is actually representative of two materials, therefore, with an elastic between them.; Paragraph S4.2 of the standard provides that surface materials i assemblies such as this are tested separately, unless bonded, sewed, or mechanically attached to underlying material (S4.2(a)). The reference to 'bonded, sewed, or mechanically attached' is intended to refer to materials joined uniformly by these methods, at their adjoining surfaces. The adhesion process you have used does not join the materials in this fashion, as there is a significant amount of area where the materials are not joined at all. Consequently, we would not test the assembly in the manner in which it appears in the vehicle, but would treat the material as separate material.; Yours truly, Richard B. Dyson, Assistant Chief Counsel
