Types III and IV materials shall be able to be applied directly to a clean, bare metal substrate without requiring a separate primer (other than a bond coat of the base material without aggregate) while still meeting all the performance requirements of this specification.

3.3 Resin based systems (Class 2 materials). The manufacturer is given their choice of ingredients used in the formation of the resin described in this document. For resin based systems, the allowed proportions for the ratio of resin component to hardener shall be limited to 4:1, 3:1, 2:1, or 1:1 by volume, where manufacturer’s instructions allow products to be mixed in the field by underlayment installers. When mixed and applied in accordance with the manufacturer’s instructions, the final underlayment system shall be in accordance with all requirements of this specification.

3.4 Application. The deck covering underlay materials shall adhere to the deck or structure on which applied without the use of clips or other devices welded to the deck, or other reinforcement not a part of the compound as mixed for application. Types I and II underlay materials shall be applied to clean steel surfaces which have been primed with Formula 150 in accordance with MIL-DTL-24441 and MIL-DTL-24441/20, MIL-DTL-24441/29 or an alternative primer (e.g. an approved primer under MIL-PRF-23236 or MIL-PRF-24647) if provided by the manufacturer as part of the underlay system. Types III and IV underlay materials shall be applied to a clean, unprimed metal surface, prepared in accordance with SSPC-SP 3 at a minimum.

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 III and shall be conducted at a laboratory satisfactory to the Naval Sea Systems Command (NAVSEA).

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, hardener, and resin if a resin based system) to create 7.6 liters (2 gallons) of the final mixed underlayment.

4.2.2 Formulation changes. Any change in basic ingredients or manufacturing processes (other than minor changes in pigment concentrations strictly to adjust final underlayment 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 underlayment 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 III.

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 sufficiently large enough to permit the performance of all conformance tests. At a minimum, two containers shall be selected from each lot of rubber latex or two containers of both resin and hardener, and from each lot of underlay powder. From each of the containers, enough material to provide for the application over a 0.8-square meter (9-square foot) area at a thickness of 6.4 millimeters (0.25 inch) (approximate) shall be taken. 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 underlay 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 underlayment system must be observed by a representative from the Defense Contracts Management Agency (DCMA).

MIL-PRF-3135H

4.3.3 Fire performance testing. A running total of material produced for batches shall be kept. Manufacturers’ records shall be used to determine quantities of material delivered. The fire performance tests of MIL-STD-1623 (see 3.5.11 and 4.5.11) shall be conducted as part of the lot acceptance tests once for every 45,359 kilograms (100,000 pounds) of unmixed material produced for delivery under one or more contracts or orders. If any sample fails any fire performance test, the tests of 4.5.11 shall be run on every subsequent batch until four successive batches have passed all required fire performance tests.

4.3.4 Small lots. Conformance tests shall not be required on any delivery of less than 4535 kilograms (10,000 pounds) of unmixed material. However, deliveries of such small quantities that have not been tested shall be so identified in the manufacturer’s records. Once the accumulated total of such untested deliveries reaches 4535 kilograms (10,000 pounds), sample material shall be selected and subjected to the required conformance tests identified in Table III.
