MLT 1540 Light Table - Pre-Production Model
Ref. Test & Evaluation Report -1.540 Split-Format Light Table
Mod II (NPIC/R-4670)
1. Introduction
1.1 The first production model of the lMLT 1540 Light Table is scheduled 2 5X1
to arrive on or about 1 October 1970. This table is the culmination of
18 months of development, testing, and re-work. It is to be the standard
for the table procurement package of 389 tables. As stated in the
contract, "All instruments delivered under this Contract shall also meet or
exceed the requirements of this specification (i.e., Technical Requirements
for the Production of the 1540 Split-Format Light
Table and Mount for Various Micros ereoscopes or performance of the
accepted pre-production model."
1.2 It is important that this table be given a thorough testing,
especially in regard to those features which were unacceptable when last
tested (see reference). This will insure that the tables delivered will
meet the high expectations of the community for this equipment.
2. Performance Testing
2.1 Those features which were found unacceptable in the April testing
will be tested. individually to insure that they have been modified\\and are
in good order.
2.2 The testing of these features will be documented in.a report 'supple-
mentary to\that written on the April test series.
3. Operational Inspection
3.1 In order to further assure PI compatability with this item, the
operating divisions will be asked to participate in a very brief operational
inspection.'. By this method, the changes in the item which meet performance
specifications but are not operationally suitable can be corrected.
3.2 The operational components which participated in the April evaluation
of the prototype will be asked to participate. Each component will be given
4 hours with the unit in the individual component's area. It must be
understood at the outset that only 2 classes of changes can be' accomplished
at this time: 1) Changes without which the light tables cannot be effectively
used, or 2) Minor changes whi h can be accommodated without appreciable
delay of production schedule.

4.1 Equipment Performance Branch, ESD will be requested to as~ist T'B in
formulating Acceptance Test Procedures for use 9n all incoming produc ion
units. This work must be\accomplished prior to delivery. of the first nit.
!+. Acceptance Test Procedures
4.2 The ire-production unit will be used as a test bed for these procedures
to insure~efficiency of the testing and rapid delivery of the accepted
units to the operating components.
4.3 The pre-production model will be, a completely motorized unit, as
specified for ICG/NPIC. There are two other configurations which will be
delivered to NPIC for DIAAP-9 and SPAR. NPIC will perform acceptance
testing on these units, using the standard procedures (where applicable)
and the contractural specifications for these components which differ from
the pre-production configuration.
5. Scheduling
5.1 The attached schedule has been coordinated within TSG and with the
operating components. The actual delivery date is unknown at this time,
therefore elapsed time from arrival, and not dates, are used.
5.2 If deviations from the schedule are required, this should be
coordinated with TEB. All affected components will be notified in this
eventuality. ~

3.5.6.2 Welds, resistance, electrical interconnections.- Welds,
resistance, electrical interconnections shall be in accordance
with MIL-STD-454, Requirement 24.
3.6 Nomenclature, identification, marking and labels.
3.6.1 Nomenclature (item name and type designation).-
The
criteria for standardized nomenclature (item name and
type
designation) shall be in accordance with MIL-STD-454,
Require-
ment 34..
3.6.2 Identification marking.- The equipment and subsidiary
levels through parts shall be marked for identification purposes
in accordance with MIL-STD-130.
3.6.3 Reference designations.- Unless otherwise specified (see
6.2.u.) each part having electrical circuits or connections
shall be identified by an appropriate reference designation in
accordance with ASA Y32.16 1965. The reference designation
shall be marked on the chassis, or other mounting surface; but
if space is not available, the reference designation shall be
marked on the part itself, provided it is not a replaceable
part. The reference designations shall be the same as those
used for identifying parts on all type of data including,
drawings, diagrams, and spare parts lists prepared for the
equipment.
3.6.3.1 Fuses and lamps.- Reference designations shall not be
marked on fuses or lamps. The reference designation of the
fuse or lamp shall be marked adjacent to the fuse holder or
lamp socket. Where space is limited, as in the case of panel
mounted fuses and lamps, the reference designation of the fuse
holder or lamp socket may be omitted to provide space for
the reference designation and rating of the fuse or lamp.
3.6.3.2 Electron tubes, transistors, and crystal units.- Reference
designations shall not be marked on electron tubes, transistors,
or crystal units. The type number and reference designation
of each tube or crystal unit shall be marked adjacent to the
tube or crystal-unit socket, on the plug-in side of the chassis.
The reference designation for the socket shall be marked on the
reverse side of the chassis adjacent to the socket. When space
is not available for marking the required tube and crystal unit
reference designations and type numbers, a suitable label showing
location of the tubes and crystal units and the corresponding
reference designations shall be mounted inside the chassis, where)
it will be readily visible when viewing the tubes and crystal
units in place.
