It is more stringent than MIL-F-15733 requiring 100% screening that includes thermal shock, voltage conditioning and x-ray. Periodic Group B testing is performed on units selected at random from production lots. Class B Test Sequence Summary Inspection Group I Class B X Voltage and temperature limits of capacitance X Insertion loss (at temperature) X Barometric pressure (reduced) X Temperature rise X Current overload X Terminal strength X Group II X Subgroup 1 X Life Subgroup 2 Resistance to soldering heat X Salt spray (corrosion) X Radiographic inspection X Subgroup 3 Group III “R” level screening is performed by Spectrum Control’s Hi-Rel Laboratory as detailed below. Customers requiring special tests may order to their own specifications or simply order to level R and then note additions or deviations. “R” level test sequence (100% testing unless otherwise specified) Thermal Shock: 5 cycles from -55°C to +125°C in accordance with MIL-STD-202, Method 107D, Condition A. ■ Burn-in: 100 hours at 1.4x rated DC voltage, 125°C. ■ Seal Test: MIL-STD-202, Method 112, Test Condition A. Hermetic seal parts only. ■ Capacitance and Dissipation Factor: MIL-STD-202, Method 305, frequency 1kHz. ■ Dielectric Withstanding Voltage: 2.5 times the rated DC voltage for 5 ± 1 second at 25°C, with 50 mA maximum charging current. ■ Insulation Resistance: MIL-STD-202, Method 302, 125°C at rated DC voltage and room temperature (25°C). The 125°C requirement shall be 10% of the specified catalog IR at 25°C. ■ DC Resistance: MIL-STD-202, Method 303. ■ Insertion Loss Test — Sample per MIL-F-15733. At full rated load in accordance with MIL-STD-220. The minimum insertion loss shall be defined in the filter catalog. ■ Visual and Mechanical: in accordance with MIL-F-15733. ■ Marking: All filters which have successfully completed the test sequence shall be marked with an “R” in the second part of the number. For example, a standard SCI-2130-004 becomes SCI-R2130-004 and 9051-1000000 becomes 9051-R100-0000, and 51-719-011 becomes 51-R719-011 after completion of the Hi-Rel Level “R” Test Sequence. ■ AC voltage drop (when applicable) Thermal shock and immersion “R” level testing Resistance to solvents X Shock (specified pulse) X Vibration (high frequency) X Moisture resistance X Seal (when applicable) X Radiographic inspection X API TECHNOLOGIES • 8061 Avonia Rd. • Fairview, PA 16415 • Ph: 814-474-1571 • Fax: 814-474-3110 • eis.apitech.com API TECHNOLOGIES’ SPECTRUM CONTROL GmbH • Hansastrasse 6 • 91126 Schwabach, Germany • Phone: (49)-9122-795-0 • Fax: (49)-9122-795-58 CF8
