Dear Mr. Lomash: This is in response to your letter of September 11, 1975, in which yo asked whether Standard No. 217 requires a minimum retention or force in pushing out an emergency exit window after activation of the release mechanism.; You should note that the force applications specified in S5.3.2 fo operation of the release mechanism and subsequent extension of the exit by an occupant are maximum requirements. Therefore, a push-out window which only requires enough force to lift the glass and subframe following operation of the release mechanism complies with the requirements of S5.3.2 and S5.4 as long as that force does not exceed the levels specified for the particular reach distance of the release mechanism.; The standard specifies no minimum force requirements for either th operation of the release mechanism or the extension of the exit following release.; Sincerely, Frank A. Berndt, Acting Chief Counsel
