Materials. It is encouraged that recycled material be used when practical as long as it meets the
3.2
requirements of the specification. The marking materials shall consist of pigmented type elastomeric sheeting
material with an adhesive applied on one side. The adhesive backing shall be protected by a removable liner.
When specified (see 6.2), the material shall be covered on the face side with a low tack, translucent transfer
sheet (see 6.1.4). Marking material in roll and sheet form (see 3.5.1) shall be not more than one year old as
measured from date of manufacture to date of delivery to the Government. Marking materials and markers
shall have the following minimum amounts of the material manufacturer's warranted shelf life remaining at the
time of delivery to the Government (see 4.4.2.4 and 6.4):
Rolls and Sheets:
12 months
All types and classes
Markers:
12 months
Type I and II, class 1
10 months
Type I and II, class 2
Type III, class 1
3.2.1 Liner. The liner shall be of such a material (e.g., paper) as to permit easy removal without
requiring water or other solvents for fast, distortion-free application of the marking materials. During removal,
the liner shall not break and shall not remove the adhesive from the marking material when tested as specified
in 4.4.2.5.
3.2.2 Translucent transfer sheet. When required (see 3.2 and 6.2), the transfer sheet to be applied
to the face side of marking material, to facilitate application or for other purposes, shall be translucent paper or
film, coated on one side with low-tack, pressure-sensitive adhesive. When the marking material is attached in
its final position, the transfer sheet shall be removable in one or a few large pieces, and without visible residue
of adhesive left on the marker face or on the application surface.
3.3
Color. The face colors of the marking materials shall be either inherent in the pigmented,
elastomeric materials, or coated on their surface. The colors shall be as specified (see 6.2) and conform to
FED-STD-595 when tested as specified in 4.4.2.5.
3.3.1 Gloss (class 1 only). When tested as specified in 4.4.2.5, the gloss of glossy, pigmented,
elastomeric, class 1 marking materials shall be 40 minimum, and the gloss of lusterless, class 1 marking
materials shall be 6 maximum.
Adhesive.
3.4
3.4.1 Type I. the adhesive backing shall be pressure sensitive and shall require no heat, solvent, or
other preparation for adhesion to smooth, clean surfaces.
3.4.2 Type II. The adhesive backing shall be positionable, pressure sensitive, and shall require no
heat, solvent, or other preparation for adhesion to smooth, clean surfaces. The marking material shall be
positionable at standard conditions and at 100° F without damage to the marking materials when tested as
specified in 4.4.2.5.
3.4.3 Type III. The adhesive backing shall be tack-free at standard conditions and shall be
activated by applying heat in excess of 175° F to the material. The adhesive shall be positionable at standard
conditions when tested as specified in 4.4.2.5.
3.5
Form.
3.5.1 Rolls and sheets. The marking materials shall be supplied in sheet or roll form, in sizes as
specified (see 6.2). Rolls shall be evenly and tightly wound with the liner side in, on a core of sufficient rigidity
to prevent distortion of the roll. Rolls shall contain not more than an average of two splices and no roll shall
contain more than four splices per 50 yards of length.
