MIL-PRF-24613A(SH)
3.5.14.2 Adhesive strength after aging. The adhesive strength of the deck covering system (including any
required primer and/or underlayment) after aging shall be not less than 70 percent of the initial adhesive strength.
3.5.14.3 Adhesive strength after exposure. The adhesive strength of the deck covering system (including any
required primer and/or underlayment) after exposure to moisture and temperature shall be not less than 70 percent of
the initial adhesive strength.
3.5.15 Slip resistance. When tested in accordance with ASTM C1028, the deck covering system [including any
required seal coat(s)] shall not be less than 0.70 dry and 0.60 wet.
3.5.16 Wear resistance. The material loss of the deck covering system [including any required seal coat(s)]
shall not exceed 30 milligrams.
3.5.17 Serviceability. The deck covering system [including any required primer, underlayment and/or seal
coat(s)] shall satisfactorily perform its function when examined during and after the minimum shipboard service
period specified. Types III, IV, V and VI deck covering systems shall not require any initial seal coat(s), and shall
not require any sanding or resealing throughout the specified in-service testing period for each Type.
3.5.18 Off-gassing (Grade A only). The deck covering system [including any required primer and/or bond
coat, underlayment and/or seal coat(s)] shall be tested for off-gassing in accordance with the Material Control
program of NAVSEA S9510-AB-ATM-010, and shall be certified for and assigned a usage category of either
"Limited" or "Permitted" (see 4.5.18 and 6.5).
4. VERIFICATION
4.1 Classification of tests. The inspection requirements specified herein are classified as follows:
a.
Qualification tests (see 4.2).
b.
Conformance tests (see 4.3).
4.2 Qualification tests. Qualification tests shall consist of all of the tests listed in Table IV.
4.2.1 Qualification sample. The qualification sample shall be drawn from a production batch and shall consist
of enough component materials (e.g., aggregate, base, hardener and sealer for a two-component Type I, Class 3
system) to create 2 gallons (~8 liters) of the final mixed deck covering.
4.2.2 Formulation changes. Any change in basic ingredients or manufacturing processes (other than minor
changes in pigment concentrations strictly to adjust final deck covering system color) that would affect compliance
with this specification must be reported to both the contracting activity and NAVSEA. The Government reserves
the right to require that all tests specified in this specification be re-performed on a production batch of the deck
covering produced under the new formulation or process before any shipment is accepted. Any formulation change
not disclosed to NAVSEA will result in immediate disqualification of the product.
4.3 Conformance tests. Conformance tests shall consist of specific tests identified in Table IV.
4.3.1 Lot. All unmixed material of the same type, but not more than a daily production run, offered for
delivery at one time, shall be considered a lot for purposes of conformance testing. The addition of any substance to
a batch shall constitute a new lot and full conformance testing is required.
4.3.2 Sampling for conformance testing. The contractor shall select a production sample of each component of
the deck covering system (e.g. resin base, hardener, aggregate, and seal coat for a Type I, Class 3 system)
sufficiently large enough to permit the performance of all conformance tests. If testing cannot be performed at the
manufacturer's facilities, two representative packaged samples shall be forwarded to an unaffiliated third party
laboratory for verification tests. If the deck covering material is to be applied to sample panels at the vendor's
facility and forwarded to an external laboratory for testing, preparation of the panels and application of the deck
covering system must be observed by a representative from the Defense Contracts Management Agency (DCMA).
