No one knows how many died in the "field testing."

Field testing of the fungus is at least three to five years away.

The companies said field testing of the new service would begin this year and become commercially available in early 1995.

Initial field testing found Garlon-4 less than fully effective in any event.

After field testing, up to 36 additional power cars could be converted.

Practically, however, Storm is still not completely ready for field testing.

Computer design may be my forte, but it just doesn't take the place of field testing.

The services were adjusted in the light of feedback from this "field testing".

Clearly the field testing of plant and equipment in service by the above method, although it has been done, is not very convenient.

This leads to the use of larger sample sizes for field testing.
