PROCEDURE.

6.1

The manufacturer of the material shall submit the Preliminary Product Material
Evaluation Form (Appendix A) for each model and type of external time clock,
which the manufacturer is requesting to be added to the listing.

6.2

The manufacturer of the material shall submit with the Evaluation Form the
following:

6.2.1

An invoice showing an initial zero dollar amount ($0.00) for the use of the
evaluation sample material during the evaluation. The invoice shall also
list the deferred cost of the material the Department would pay if the
material is purchased instead of returned upon the successful completion
of the evaluation.

6.2.2

Operation and maintenance manual(s) which includes theory of operation,
schematics and component parts listing

6.2.3

Three randomly selected production run time clocks for bench and field
testing

6.2.4

List of required software and any other additional items required to realize
the full potential of the product

7.0

SUBMITTAL REVIEW. The documentation, including the environmental testing, will
be reviewed for usability of the external time clock. The manufacturers recommended
schedule and extent of maintenance will be reviewed for acceptability.

8.0

BENCH TESTING. The external time clock will be bench tested for required
functionality and full manufacturers claimed optional functionality.

9.0

FIELD TESTING.

9.1

The field testing of the external time clock will consist of installing the external
time clock in actual traffic for a period of up to 12 months to monitor the
following:

9.1.1

Any failures for the external time clock

9.1.2

The relative ease of use for the field personnel

9.1.3

Overall build quality and expected lifecycle of the external time clock.
This requirement shall be comparable with existing approved external
time clocks. ITM 935-08P

10.0

REPORT. A final report will include the notations and findings from the electronic
bench test and field testing results and documentation.

11.0

APPROVAL LIST.

11.1

Approval of external time clock. The external time clock model may be placed
on the approval list when the following conditions are met:

11.1.1

A potential net benefit to the Department is realized by inclusion of the
item on the list.

11.1.2

The required documentation is submitted.

11.1.3

The bench and field testing are completed with satisfactory results.

11.1.4

No excessive amount of routine or periodic maintenance is required.

11.1.5

The external time clock shall include all manuals, documents, and
software to realize the full potential of the external time clock.

11.1.6

Only minimal maintenance operations were necessary during the field
testing.

11.2

Maintaining Approval.

11.2.1

The Highway Operations Division Evaluations Section shall be notified
each time any update or revision of the firmware or software is made, and
the changes and benefits of the change shall be submitted for approval.
The Department will determine if and to what extent a revision is to be
placed into field operation and may fully re-evaluate the time clock with
the revision.

11.2.2

If the manufacturer makes any changes to an approved model to correct a
safety issue, the Department shall be notified immediately. The
manufacturer shall correct all existing equipment purchased by the
Department either directly, by contract, or through agreement prior to the
change being incorporated at the manufacturers production level.

11.2.3

A design change to an approved model shall require a submittal of
documented changes. At the discretion of the Department, resubmission of
the model for testing and evaluation may be required. Permanent addition
or removals of component parts or wires, printed circuit board
modifications or revisions to memory or processor software, are examples
of items that are considered to be design changes. ITM 935-08P

11.3

Removal from Approval List. The external time clock will be removed from an
approval list for, but not limited to, the following reasons:

11.3.1

Changes in the external time clock components or production process that
fail testing and/or evaluation

11.3.2

If three consecutive years elapse without furnishing the external time
clock

11.3.3

Performance of the external time clock no longer meets the intended
purpose

11.3.4

Recurring similar product failures indicative of a manufactures defect
