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. |
