This

has
been
produced
through
the
Environmental
Data
Standards
Council
(
EDSC).

The
Environmental
Data
Standards
Council
(
EDSC)
is
a
partnership
among
EPA,
States
and
Tribal
partners
to
develop
and
agree
upon
data
standards
for
environmental
information
collection
and
exchange.

Foreword
The
Environmental
Data
Standards
Council
identifies,
prioritizes
and
pursues
the
creation
of
data
standards
for
those
areas
where
information
exchange
standards
will
provide
the
most
value
in
achieving
environmental
results.
The
Council
involves
Tribes
and
Tribal
Nations,
state
and
federal
agencies
in
the
development
of
the
standards
and
then
provides
the
draft
materials
for
general
review.
Business
groups,
non­
governmental
organizations,
and
other
interested
parties
may
then
provide
input
and
comment
for
Council
consideration
and
standard
finalization.
Draft
and
final
standards

INTRODUCTION
This
Measure
Data
Standard
focuses
on
data
elements
used
to
identify
and
describe
recorded
measurements
or
analytical
results
that
are
being
exchanged
between
data
trading
partners.
There
are
many
categories
or
types
of
measurement
where
the
units
in
each
type
are
mutually
comparable.
For
example,
lengths,
diameters,
distances,
heights,
wavelengths
constitute
such
a
category.
Mutually
comparable
quantities
are
called
"
quantities
of
the
same
kind".
Each
category
of
measurement
has
an
allowed
set
of
units
of
measure.
Two
or
more
physical
quantities
cannot
be
compared
unless
they
belong
to
the
same
category
of
measurements.
Some
example
categories
of
measurements
include:
length,
mass,
time,
temperature,
amount
of
substance,
velocity,
force,
relative
density,
illuminance,
and
entropy.

1.1
Scope
This
data
standard
provides
and
describes
data
groupings
that
are
used
to
exchange
data
about
recorded
measurement
or
analytical
results.

1.3
Terms
and
Definitions
For
the
purposes
of
this
