Dear Mr. Morton: This is in reply to your letter of September 28, 1972, concerning th application of Paragraph S5.2.2 of Motor Vehicle Safety Standard No. 302, 'Flammability of Interior Materials.' You ask whether, in testing automotive interior fabrics, test specimens 'must be burned in warp and filling directions only, or does it also include testing in the face-down (inverted) positions?' As you point out, under the standard test specimens for each component are to be tested 'so as to provide the most adverse results.' This means that the relevant test result is the most adverse one achieved in any horizontal orientation, either upward- or downward-facing. How you determine which positioning of the test specimen produces the most adverse results is within your own discretion.; Yours truly, Richard B. Dyson, Assistant Chief Counsel
