Mr. Katsuhiko Yokoi Assistant Manager - Tech. Dept. Toyoda Gosei Co., Ltd. 1, Nagahata, Ochiai, Haruhi-mura Nishikasugai-gun Aichi-pref., 452 JAPAN

Dear Mr. Yokoi:

The answers to the questions in your letter of January 20, 1982, are "yes" to both questions.

1. The "adjacent layers" referenced in Federal Motor Vehicle Safety Standard (FMVSS) No. 106, paragraphs S7.3.7, are (a) the inner tube and braided layer and (b) the braided layer and outer tube.

2. The adhesion requirements are met if both the tensile strengths measured between (a) the inner tube and braided layer and (b) that between the braided layer and the outer cover are equal to or greater than 8 lbs/inch as determined using the FMVSS No. 106 procedure. It should be noted that the 8 lbs/inch value is an absolute minimum value as indicated in paragraph S8.6.4(a) standard.

A copy of FMVSS No. 106 is included for your information.

Sincerely,

Vernon G. Bloom Safety Standards Engineer

Enclosure FMVSS No. 106
