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.
RTCA is pleased to announce the exciting array of information packed sessions at the upcoming RTCA 2014 Annual Symposium. Industry leaders should plan to attend the Symposium at the Walter E. Washington Convention Center in Washington, DC on June 4th & 5th.
April 29-30 – Shock & Vibration – Test, Design & Design Assurance by Dr. Alec Feinberg - Cost: $1,195 Understanding of vibration and shock stress is important for the design of reliable products for diverse applications, ranging from consumer devices to safety critical equipment. This course starts by covering vibration and shock concepts, test methods and test equipment. Practical examples illustrate the concepts and attendees will perform calculations themselves to reinforce learning.
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!
With the legalization of marijuana across nation, vacuum drying has been getting a lot of attention lately. For cannabis extractors, BHO extraction uses vacuum drying to help remove impurities while making THC extractions. But the truth is medical device, food and aerospace industries have been capitalizing on the benefits of low temperature vacuum drying for decades.
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 )
Attention all Colorado EMC and Product Safety Customers! EMC Integrity will be co-hosting a free, 1-day seminar on January 28th to give clients an overview of EN 61326-1 as well as EN 61010. EMCI's co-host will be NSS Labs, based in Ft. Collins. NSS Labs specializes in product safety, and has recently joined EMCI as a Nemko partner-lab. As a result, the
Since 1952, the Constitution has been on display in the National Archives Building in Washington, DC. Currently, all four pages are displayed behind protective glass framed with titanium.
Most accelerated weathering test chambers are designed to test a sample or “coupon” of a product – meaning a sample of the paint, coating or portion of the product that will be exposed to UV, heat/humidity. But if you want the entire product to be exposed Cascade TEK's MacGyver-like Test Technicians have modified our accelerated weathering test chambers to accommodate products much larger than just a sample or coupon size.
