2.4 Order of precedence. Unless otherwise noted herein or in the contract, in the event of a conflict between the text
of this document and the references cited herein (except for related specification sheets), the text of this document
take precedence. Nothing in this document, however, supersedes applicable laws and regulations unless a specific
exemption has been obtained.
3. REQUIREMENTS
3.1 Specification sheets. The individual item requirements shall be as specified herein and in accordance with the
applicable specification sheet. In the event of any conflict between requirements of this specification and the
specification sheets, the latter shall govern.
3.2 First article. When specified (see 6.3), a sample shall be subjected to first article inspection in accordance
with 4.4.
3.3 Materials. Materials shall be as specified herein and shall conform to all applicable specification sheets. When a
definite material is not specified, a material shall be used which will enable the pump to meet the requirements of this
specification. Acceptance or approval of any constituent material shall not be construed as a guarantee of
acceptance of the finished product.
3.3.1 Recycled, recovered, or environmentally preferable materials. Recycled, recovered, or environmentally
preferable materials shall be used to the maximum extent possible provided that the material meets or exceeds the
operational and maintenance requirements, and promotes economically advantageous life cycle costs.
3.3.2 Metals. All metals shall be compatible with the fluid and intended temperature, functional, service, and storage
conditions to which the components will be exposed. The metals shall possess adequate corrosion-resistant
characteristics or shall be suitably protected by the use of coatings equivalent to those listed in table I to resist
corrosion which may result from such conditions as dissimilar metal combinations, moisture, salt spray, and high
temperature deterioration, as applicable. Where not indicated, class or type is at the option of the manufacturer,
subject to approval by the procuring activity. Dissimilar metals are defined in MIL-STD-889.
3.3.2.1 Copper or aluminum alloys. All copper alloys shall be suitably protected with a coating specified in table I,
except that cadmium and zinc plating shall not be used in applications subject to abrasion. Other metallic coatings,
which shall have been demonstrated to be satisfactory to the Government, such as electroless nickel and
electrodeposited 85 percent tin, 15 percent cadmium alloy, may be used. All aluminum alloys shall be anodized in
accordance with MIL-A-8625, type II coating, except that in the absence of abrasive conditions the anodize may be
type I coating, where applicable, or may be a chemical film in accordance with MIL-DTL-5541.
