of chart F4 indicated in the ESA Generic Specification ESCC 4001. The testing to be performed and the sample size shall be as

stipulated in the purchase order. When procurement of more than one component type is involved from a family, range or series,

the selection of representative samples shall also be stipulated in the purchase order.

Lot validation testing will be composed of one LVT charges and LVT samples:



Lot validation test charges has to be ordered separately on purchase order.



Lot validation samples have to be ordered separately on purchase order.

FINAL INSPECTION

If requested by the orderer a final inspection can be performed on site.



Final inspection has to be stipulated separately on purchase order.

SPECIAL FEATURES

Resistance values can be different on a given network

(R max./R min. as high as 300). Tooling charges might

be required depending on the ohmic values in the

same network. Please, consult Vishay Sfernice for ohmic

values, tolerances and also temperature coefficient outside

the standard range.
