Thanks for Seidio for mentioning Cascade TEK in its product literature for the OBEX Waterproof case to withstand a battery of ingress protection testing.  The case has been tested to be waterproof, impact resistant and dust tight.

Introduction Shelf Life Validation Testing

Steve McKelvey was one of Cascade TEK’s great testing customers before retiring to Mexico.  So clearly, he’s a genius. 

Let me share his notes from his presentation “Introduction to Shelf Life Validation”.   Steve covers:

  • Developing a Shelf-Life Test Plan
  • Sample Size Justification
  • Device Shelf Life
  • Humidity vs. Laminated Films

Testing Things We Put Into Space

hi-vac bakeouts at Cascade TEK

Space hardware must be free of contamination and be able to withstand radiative behavior of temperature and the very thin atmosphere of space.   100Km straight up  is the Karman line.  This is where the atmosphere becomes too thin to support lift.  Satellites generally fly at about 300 Km above the earth, which for vacuum folks is about 10-6 torr.   Cascade TEK’s SVO hi-vac ovens can reach 10-6 and often into the 10-7 torr range.

UV light testing - how long in a chamber

Many of our customers who want to perform accelerated weathering tests ask us how long in a test chamber equates to 1 year outdoors.   Unfortunately, there is no direct correlation.   Cascade TEK's accelerated weathering webpage offers more detail, but don’t take our word for it.  Attached is an article from Q-Lab Corporation, one of the leading manufacturers of weathering/UV exposure chambers.

Cascade TEK is thrilled  to be testing for Tissue Genesis this week.  Their Bioculture System (pictured) will be growing cells on THE INTERNATIONAL SPACE STATION!   Thank you Tom Cannon who left the sultry, warm Honolulu tropics to test with Cascade TEK in Oregon. And a special hello to the ISS Expedition 38 Crew!
 

UV Exposure Testing - Bulb Types

UV exposure testing, accellerated weathering test

Here is a quick run-down on the types of bulbs used in UV, Accelerated weathering tests. 
 
There are many different spectral irradiances of UV bulbs.  Generally speaking: 
500 hours under UV-B bulbs = 1 year of South Florida exposure
1000 hours under UV-A bulbs = 1 year South Florida exposure
1000 hours under Xenon Arc = 1 year South Florida exposure
There are additional UV exposure categories for an Arizona climate.  (Dry, more intense UV & heat )
UV-A Bulbs:
