TITLE: BURNING BEHAVIOUR OF INTERIOR MATERIALS FOR MOTOR VEHICLES

ATTACHMT: ATTACHED TO LETTER DATED 5-9-75 TO MR. SICKS FROM RICHARD B. DYSON

TEXT: In March 1975 the ISO Central Secretariat has published DRAFT INTERNATIONAL STANDARD

ISO/DIS 3795 - Road vehicles - Determination of burning behaviour of interior materials for motor vehicles

Please find enclosed the English version of this Draft International Standard. As mentioned in our letter of September 3, 1974 Sub-Committee 16 decided to require in this Draft International Standard the presence of supporting wires in all cases in order to avoid subjective interpretations of sample behaviour by the test personnel. As it is essential that laboratories charged with flammability tests conduct these tests according to the same procedure, we ask you to take into consideration the specifications of ISO/DIS 3795. We would appreciate it very much, if you could modify MVSS 302 so that also this standard requires the presence of supporting wires in all tests. We look forward to receiving your reply.
