the contract or order (see 6.2). When actual packaging of materiel is to be performed by DoD
personnel, these personnel need to contact the responsible packaging activity to ascertain
requisite packaging requirements. Packaging requirements are maintained by the Inventory
Control Point's packaging activity within the Military Department or Defense Agency, or within
the Military Department's System Command. 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.
6. NOTES
(This section contains information of a general or explanatory nature that may be helpful, but
is not mandatory.)
6.1 Intended use. The elements are intended for use in military filter-separator vessels to
remove solid contaminants and coalesce water from diesel and jet fuels. The elements covered
by this performance specification are military unique since they must interface with the family of
military standard filter/separators.
6.2 Acquisition data. Acquisition documents should specify the following:
a. Title, number, and date of this specification.
b. Class of filter-coalescer element required by the Government (see 1.2).
c. Issue of DoDISS to be cited in the solicitation, and if required, the specific issue of
individual documents referenced (see 2.2).
d. If first article inspection is required (see 3.1 and 4.2), the total number of samples, and
number of elements per each FAT set (see 4.5).
e. Identification markings including NSN, contract or order number, lot number,
manufacturer's identification, date of manufacture, and fuel category compatibility (see
3.6.1).
f. When lot size other than as specified (see 4.3.1).
g. Number of samples per production lot that shall undergo conformance inspection (see
4.3.2).
h. Test data sheets as provided in API 1581, Table 6 Data Sheet for Single-Element Tests,
Type S Filters, and Table 7 Data Sheet for Full-Scale Tests, Type S Filters.
i. Selection of applicable packaging and packing requirements (see 5.1).
6.3 Disposition of test assemblies. Elements undergoing destructive tests should be indelibly
marked "DO NOT USE".

more, and a length of 100 microns or more.
6.4.2 Differential pressure across the element. The differential pressure across the element is
defined as the pressure drop across the filter/separator with the element installed measured from
