MIL-DTL-43719D
Class 2 material. The specimens shall be those used for the printability test in 4.6.11. The
4.6.15.2
specimens shall be exposed to accelerated weathering according to ASTM D822 for 96 hours. The specimens
shall then be examined and tested according to the requirements of 3.7.8 and 3.7.12.2. The examination for
sharpness and legibility of the printed letters shall be made from a distance of 6 feet.
4.6.16
Hiding power. Hiding power of marking material shall be determined in accordance with
ASTM D2805, except that the material shall be applied to the black and white Carrara glass as specified in
4.5.3.
4.6.17
Storage stability. Marking material to be tested shall be stored at a temperature of 70° F to
90° F for the following number of months after manufacture:
Type I and II, class 1
- 24 months
Type I and II, class 2, and type III, class 1
- 12 months
The material shall then be tested for conformance to the requirements listed in table III, except for weathering
resistance and storage stability.
4.6.18
Positionability test (type II and III). The length of the test specimen shall be 8 inches. The
width shall be the full width of the tape up to 3 inches wide. Material over 3 inches wide shall be cut to 3
inches. One specimen shall be conditioned and tested at standard conditions (type II and III), and one
specimen shall be conditioned for 1 hour and tested at 100° ± 2° F (type II only). A 4 by 8 inch aluminum test
panel shall be conditioned with the specimens and the test shall be performed as follows: Crease one end of
the specimen sharply back against its face to form a tab ½ inch long. Completely remove the liner from the
specimen. Hold the tabbed end of the specimen and, with the test panel held securely, position the specimen
gently on the test panel with the long dimension of the specimen and panel parallel. Do not press specimen
against panel. After 10 seconds, hold the tab, slide the specimen slowly along the long dimension of the test
panel; if the specimen does not slide, lift the specimen off the panel. After the test, the specimen shall be
examined for any evidence of damage (e.g., distortion of tearing) to the specimen and for any removal of
adhesive from the specimen. Any damage or removal of adhesive constitutes failure.
5.
PACKAGING
5.1
Packaging. For acquisition purposes, the packaging requirements shall be as specified in the
contract or order (see 6.2). When packaging of material is to be performed by DoD or inhouse contractor
personnel, these personnel need to contact the responsible packaging activity to ascertain packaging
requirements. Packaging requirements are maintained by the Inventory Control Point's packaging activities
within the Military Services or Defense Agency, or within the military service's system commands. Packaging
data retrieval is available from the managing Military Department's or Defense Agency's automated packaging
files, CD-ROM products, or by contacting the responsible packaging activity.

NOTES
(This section contains information of a general or explanatory nature that may be helpful, but is not mandatory.)
6.1
Intended use. Class 1 marking material is used in the manufacture of markers that are
permanent in nature. The markers are then to be applied, by means of their adhesive layer, on exterior and
interior surfaces of automotive vehicles, aerospace and ground support equipment, on interior surfaces of
aircraft, and in other applications as required or permitted. Class 2 marking material is intended for use in
preparation of temporary identification and instruction markers in shipment and storage of supplies and
equipment as provided in MIL-STD-129. An important characteristic of class 2 material; e.g., in marking of
vehicles during shipment and storage, is that it is readily removable even after extended weathering. These
materials are not intended to be used on surfaces which become heated above 150° F. For exterior markers of
the United State Air Force aircraft, the applicable material is covered by A-A-59485.
