New
refrigerators no longer use chlorofluorocarbons which
deplete Earth's ozone layer. NIST provided data on ecologically
sound refrigerants for replacing CFCs.
NIST
prepares more than 35 different food Standard Reference
Materials, which are homogenized samples of real foods
or plants. Food processing companies analyze the SRMs
and, if necessary, adjust their equipment to match the
values provided.
Yellow
stickers on every new refrigerator tell how much energy
it will use. NIST and the Department of Energy developed
the standards for these ratings.
