MIL-PRF-23827C
6.3.1 Submission of samples. Prior to submitting samples for qualification testing,
manufacturers will request authorization from the qualification activity. Upon receipt of
authorization, the samples will be forwarded as directed. The qualifying activity will require the
manufacturer to submit for review and approval, two copies of the manufacturer's test report,
including the sample's Material Safety Data Sheet (MSDS) (see 6.5), the location and identity of
the plant which produced the sample, and the item composition report. The samples should be
plainly and durably marked with the following information:
Sample for qualification inspection.
GREASE, AIRCRAFT AND INSTRUMENT, GEAR AND ACTUATOR SCREW,
NATO CODE NUMBER G-354, METRIC
Name of manufacturer.
Product code number.
Batch number.
Date of manufacture.
Submitted by (name) (date) for qualification inspection in accordance with
MIL-PRF-23827C under authorization of (reference authorizing letter) (see 6.3).
6.3.2 Retention of qualification. In order to retain qualification of a product approved for
listing on the Qualified Products List (QPL), the Government will require the manufacturer to
verify by certification to the qualifying activity that the manufacturer's product complies with the
requirements of this specification. The time of periodic verification by certification will be in two
year intervals from the date of original qualification and will be initiated by the Government. The
Government reserves the right to re-examine the qualified product whenever deemed necessary to
ensure that the product continues to meet any or all of the specification requirements.
6.4 Lot and batch. A lot is the grease produced by one manufacturer at one plant from the
same materials and under essentially the same conditions, provided the operation is continuous
and does not exceed a 24-hour period. In the event the process is a batch operation, each batch
constitutes a lot. A batch is that quantity of material which has been manufactured by the same
unit chemical process and subjected to the same physical mixing operation intended to make the
final product substantially uniform.
6.5 Material safety data sheets (MSDSs). Contracting officers will identify those activities
requiring copies of completed Material Safety Data Sheets prepared in accordance with
FED-STD-313. The pertinent Government mailing addresses for submission of data are listed in
FED-STD-313; and 29 CFR 1910.1200 requires that the Material Safety Data Sheet for each
hazardous chemical used in an operation must be readily available to personnel using the material.
