1:2:3 (a) The ISO 14000 family of standards play an 1 10
important role in supporting GE. 2

These standards guide corporate entities 1
in key areas of their operations so they 1
meet the requirements so as to be 1
environmentally responsible. 2
1
These standards allow similar processes
in different organizations to be compared 1
with each other.

This in turn allows for easy integration
of processes or utilization of material.

The ASTM standards play an important role
in ensuring that materials, equipment and
testing procedures are to the required
technical specifications of the process.

These test standards ensure that all
testing procedures are done in the
identical manner regardless of which
organization the testing is done at.

This allows the empirical comparison of
materials and makes their use in
different processes more acceptable.

1:2:5 (b) (i) Balance industrial inputs and 2 6
outputs to natural levels and
capacity means that there should 1
not be any output which demands 1
more than any of the complementing
input processes.

Also, these inputs should not
demand more than can be supplied by
the natural environment.

This supply should not have any
negative impact on the health of
the environment.
