3.11 Resistance temperature characteristic. When resistors are tested as specified in 4.6.9, the
resistance temperature characteristic shall meet the requirements in Table III.
3.12 Shock. When resistors are tested as specified in 4.6.10, there shall be no evidence of mechanical
damage, and the change in resistance shall not exceed the performance requirement in Table IV.
3.13 Vibration. When resistors are tested as specified in 4.6.11, there shall be no evidence of
mechanical damage, and the change in resistance shall not exceed the performance requirement in
Table IV.
3.14 Resistance to solvents. When resistors are tested as specified in 4.6.12, there shall be no evidence
of mechanical damage, and the marking shall remain legible.
3.15 Terminal strength. When resistors are tested as specified in 4.6.13, there shall be no evidence of
mechanical damage, and the change in resistance shall not exceed the performance requirement in
Table IV.
3.16 Solderability. When resistors are tested as specified in 4.6.14, the criteria for wire-lead terminal
evaluation that is contained in the referenced test method shall be met.
3.17 Marking. Each resistor shall be marked with the Goddard part number, source code,
manufacturer's name or symbol (optional), and date code. Date and source code shall be in
accordance with MIL-STD-1285. The location and number of lines shall be at the discretion of
the manufacturer. The following is an example of the complete marking:
Caddock -Manufacturer's name or symbol (optional)
19647 -Source code
G311P683 -Goddard designator
7501006D -Style, resistance value and tolerance
9626 -Date code
The date code shall be the date of the final assembly operation for the production lot, which for
purposes of this specification, is the same as the inspection lot (4.5.2). The common manufacturing
record shall include the same date code as that placed on parts covered by the record. When the
physical size of the resistor precludes the marking of all of the above information, the Goddard
designator may be abbreviated to P683. However, the complete part number must be marked on
the shipping container.
3.18 Workmanship. Resistors shall be processed in such a manner to be uniform in quality when
inspected in accordance with 4.6.1. Resistors shall also be free of any defects affecting life,
serviceability or performance.
4. QUALITY ASSURANCE PROVISIONS
4.1 Responsibility for inspection. The manufacturer is responsible for the performance of all inspection
requirements, as specified herein, using his own or any other suitable facility acceptable to Goddard
Space Flight Center unless specifically stated otherwise. In instances where the manufacturer does
not possess the necessary test equipment or facilities to perform a test, GSFC may elect to perform
the test. Upon receipt of product, Goddard reserves the right to perform any of the inspections set
forth in the specification where such inspections are deemed necessary to verify conformance to
prescribed requirements.
