|Choosing an Environmental Test Chamber
Nov 29, 2000
cabinets, controlled environment chambers, test chambers<\m>they
are called many things, but all of them control temperature
and/or humidity within a specific area. The laboratory manager’s
job is to determine how many chambers of a specific size are
sufficient for their current and future projects. While many
systems meet the International Conference on Harmonization
(ICH) guidelines, there are many different style chambers
available today. All have an assortment of features that can
be confusing. The following is a summary of what you will
find when shopping for an environmental chamber. “Bench” style
chambers can be up to 0.31 m3. While the name implies setting
these units on a counter, they can weigh over 136 kg depending
on the components.

of a National Weather Service (NWS) headquarters reorganization
that took effect in October of 2000, the National Data Buoy
Center (NDBC) was placed under the Office of Operational Systems.
The reorganization provided an opportunity to consolidate
NWS engineering and meteorological testing expertise, and
NDBC was given responsibility for managing surface instrumentation
test activities conducted at the Sterling Research and Development
Center (SR&DC) in Sterling, VA. This article provides
background on the newest member of the NDBC family.

scenario for an exterior paint coating is early failure when
at the mercy of demanding environmental conditions. Whilst
companies can test samples in challenging climates over the
long term, it is possible to approach the problem within a
shorter time scale by studying product behaviour under simulated
conditions in the laboratory.

called environmental chambers, but torture chambers might
be a more accurate name. Here, in these small, rectangular
boxes, products are subjected to extreme heat or cold. In
other chambers products are violently shaken or battered with
jets of water and sprays of salt and dust. Products are submerged,
suffocated, battered, twisted and eventually broken

power in telecom systems
of DC power systems take many precautions to ensure the reliable
delivery of power to the telecom system. The reliability of
the DC power systems is marketed by outlining the system features
that contribute to a continuous supply of DC power. The most
frequently cited are N+1 redundancy, load sharing, hot bus
plug-in and battery back-up.

that can mimic the environments of other planets. The chamber's
focus will be Mars, said Derek Sears, UA professor of chemistry.
The chamber is only one of two in the world used for academic
research. The other is at the German Space Agency in Cologne,
|Common Sense Approach For Good Testing
many pitfalls to avoid, especially for the entry level engineer,
when planning and conducting tests. Today’s turnkey test equipment
enables engineers and technicians, with limited testing experience,
to conduct tests relatively quickly and efficiently. However,
while computers and menu driven software have enabled testing
laboratories to become increasingly more efficient, as far
as testing productivity is concerned, a void has been created.
|Tame your environmental test projects
|| High heat.
Freezing cold. Torrential rain. Automobiles must be able to
withstand a range of extreme conditions, and the operating
environments for aircraft, especially spacecraft, are even
more severe. To effectively test complex automotive and aerospace
systems for widely varying environments, you must have the
right test procedures, the right equipment, and an effective
test process in place. The following tips will help you develop
and manage a successful environmental test project.
