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. |
NDBC Acquires Surface
Instrumentation Test Group
06-Mar-2002 |
As part 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. |
Changing climate for coatings
testing
|
The
worst-case 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. |
