Also, the item shall be capable of meeting functional requirement of 3 years storage life at various stages of spacecraft assembly and 5 years in controlled environmental condition. 1.3 The constituent material including epoxies used must be space qualified and procured from a qualified manufacturer normally associated with long life communication satellite hardware manufacturing. These materials shall have Total Mass Loss (TML) less than 1% and Collected Volatile Condensable Material (CVCM) of less than 0.1% when subjected to test condition of 1250C temperature, 10-6 torr pressure for 24 hours. Certificates in support for the material lots used for fabrication of connectors shall be supplied along with the test report of the connectors.

2.0 SCREENING :

Screening of the parts, shall be carried out, on 100% basis, as per Table-1 below. TABLE – 1 SCREENING TESTS (on 100%)

Sr. Test Applicable Specification Test condition No . 1 Thermal shock MIL-STD-202, Method 107G, -55ºC to +125 Condition `B’ ºC, 5 cycles 2 External Visual As per manufacturer’s datasheet inspection 3 Electrical MIL-STD-202, measurements Method 301 & (DWV & IR) Method 302 3.0 LOT ACCEPTANCE TESTS :

After successful completion of the Screening, 10% samples shall be randomly selected from the screened lot and subjected to Lot Acceptance Testing (LAT) as per Table-2 given below. For Subgroups 2, 3 & 4 , samples passed through subgroup 1 testing, shall be distributed among as mentioned in the Table-2.

TABLE – 2 LOT ACCEPTANCE TESTS (ON 10% SAMPLES)

Sr. Test Applicable specification & Test condition No. method Subgroup-1 ( on all sample pieces ) 1 Thermal shock MIL-STD-202, -55ºC to +125 Method 107G ºC, 50 cycles 2 External visual inspection As per manufacturer’s datasheet 3 Electrical measurements MIL-STD-202, (DWV & IR) Method 301 & 302 Subgroup-2 (on 20% of LAT samples) 4 Solderability MIL-STD-202, Method 208 Subgroup-3 (on 20% of LAT samples) 5 Terminal Strength MIL-STD-202, Condition `A’, (Pull test) Method 211 0.5lb Subgroup-4 (on 60% of LAT samples) 6 Seal MIL-STD-202, Condition `C’ Method 112 7 Humidity Storage Test MIL-STD-202, Condition `A’ Method 103

Visual inspection shall be carried out at 10X magnification minimum. Defects pertaining to Metallization, Surface finish, Discoloration, Oxidation and workmanship are not allowed. It is recommended to follow visual inspection requirements of MIL-STD-883, Method 2009. However, guidelines generated by qualifying agencies like ESCC, MIL, NASA-GSFC can also be followed for visual inspection and accept / reject criteria.

Alternate method for seal test, if being followed by manufacturer, may be proposed with its full technical details. Based on review, SAC may accept it in lieu of MIL-STD-202, Method 112C

Not a single failure is allowed during LAT. Any single failure shall call for rejection of the entire lot.

The sample piece qty. may be optimized from random selection of different pin variants of the headers. 4.0 The following details shall be supplied along with the deliverable components. 4.1 Certificate of Compliance (CoC) from Original Part Manufacturer. 4.2 Certificate of Compliance (CoC) from vendor/supplier 4.3 Screening test report 4.4 Lot acceptance test report 4.5 LAT samples

5.0 General requirements: 5.1 The parts supplied shall have a Single Lot Date Code not older than 2 years from the date shipment to SAC. 5.2 The parts shall be packed individually and packing/cushioning material shall be anti-corrosive. (Pink poly foam shall not be used)

6.0 Important Notes :

6.1 The offer by the manufacturer, having successful space heritage for either quoted or similar style parts , will be considered from QA aspects. In this case, the Space Flight History with details of Space program(s) and part nos. be supplied with the offer. 6.2 The manufacturer of the quoted part, shall preferably be Hi-rel / Space grade part manufacturer. 6.3 The Vendors/suppliers who are authorized, by the Original Part Manufacturer, to source/sell Space grade parts in India, will only be considered. Hence, the endorsed Certificate(s) issued by the Original Part Manufacturer must be enclosed with the offer. 6.4 The supplier/vendor is requested to study/examine the each point/requirement of this Annexure and must give the Compliance (or non-compliance or partial-compliance), to each requirement of this annexure, The necessary details/information substantiating the compliance shall also be provided in the quotation. FAILING WHICH THE OFFER SHALL BE REJECTED.
