Sechan operates and maintains an environmental facility capable of performing Environmental Stress Screening (ESS) and many of the common MIL-STD-810, MIL-STD-781 and MIL-STD-167 environmental test sequences. This laboratory operates in an allocated floor space of 5,000 Sq. Ft. using chambers and equipment configured with microprocessors, chart recorders, and automatic data log features as well as product over-test prevention features. The equipment is maintained and calibrated consistent with the requirements of ISO 9001:2000/AS9100 and MIL-STD-45662.

EQUIPMENT	DESCRIPTION
Temperature Chambers	Twelve chambers with microprocessor controls, charts recorders, over-temperature product safety monitors. Up to 133 cubic feet capacity and as fast as 15°C/minute change with liquid nitrogen boost. Several of the chambers have AGREE capability (combined vibration and temperature cycling)
Temperature-Humidity Chambers	Two chambers with microprocessor controls, chart recorders, over-temperature product safety monitors
Temperature Shock Chamber	Single equipment with two separate chambers and mechanical shuttle, permitting a rate of change > 80oC/minute. 20-cubic feet capacity
High Air Pressure	3500psi air compressor
Altitude	Altitude chamber, 8-cubic feet capacity and 120,000' altitude capability
Drop Transportation	Drop shock package tester
Vibration/Shock	Mechanical shaker for transportation simulation, capacity of 275 lbs
Sine Shaker Table	Three tables with 300, 400 and 1000 force-pound capability
Vibration Test Systems	Three computer-controlled slip tables, drivers and software to develop sine, random and random-on-random environments. Shaker ratings are 4,000, 7,500 and 13,000 force pounds
Shock Test	Computer controlled with data acquisition instrumentation for MIL-STD-810 shaped shock pulses, up to 400-pound capacity. Shock testing using electro-dynamic shakers with capacity up to 24,000 force-pounds peak.
Immersion	Fiberglass tank for immersion testing at a depth of up to one meter
