5、 5 3.10 ACOUSTIC OVERALL EFFICIENCY (FLTM BV 160-03) Minimum 10 dB for range 200 - 800 Hz. Note: The supplier is required to provide, together with the Initial Sample Report, specimens in dimensions as specified and of same material and equivalent manufacture used for the finished part. Samples for

6、control and routine checks shall be submitted as required by Quality Control. 3.10 AIR BORNE NOISE INSULATION (See Figure 1) Note: If the finished part does not allow the preparation of specimens in dimensions as necessary for this test, proceed according to 3.9, Note. 3.12 FINISHED PART REQUIREMENT

7、S 3.12.1 Dimensions As specified on Engineering drawing 3.12.2 Mass (kg) The tolerance in mass of the finished part for any one supplier shall be maximum +/- 10%, based on the recorded mass of his originally approved initial sample. 3.12.3 Heat Stability The part shall show no visible shrinkage or d

8、istortion, respectively it shall not warp to an extent that would affect its use in ultimate assembly. Furthermore, it shall show no change in appearance when compared with the original unaged part. Test Method: The finished part shall be subjected to a temperature of 90 +/- 2 C air temperature for

9、24 hours. Examine after cooling to room temperature. 3.12.4 Moisture Absorption, max 5% Test Method: 1) Weigh finished part nearest to 5 g. 2) Condition the part in suspended position at 98 +/- 2% relative humidity and 38 +/- 2 C for 24 hours. 3) After 1 hour at room temperature weigh the part neare

10、st to 5 g and determine increase of weight in percentage based on original weight.
